50ABE2C90B9C59B789E7DB39ABF4C497.taxon	description	Description. Morphology of the holotype is a thick-walled funnel attached to rock substratum by a wide basal disc (Fig. 2 B). Both dermal and atrial surfaces have a very dense, bushy, cover of prostal diactins (Fig. 2 C, E, F). The single terminal osculum is the widest body part and the margin is abruptly sharpened; it has no marginalia (Fig. 2 D). Dimensions of the holotype are ~ 17.2 cm high and 12.8 cm wide; the measurements are only approximate as only one of the two laser points could be certainly found on the in-situ images. Wall thickness is 10.7 cm, excluding the 1 - 2.5 cm thick prostal cover layers on each side. Texture is soft, compressible, and resilient, neither hard nor fragile. Surfaces of both the inner and outer walls are hairy to the naked eye, and when inspected at low magnification of a dissecting microscope, both are covered with a bushy layer of prostal diactins. Colour in life is pale beige, and pale brown when preserved in ethanol. Skeleton. Choanosomal skeleton consists of a loose network of thin choanosomal diactins amongst the thicker proximal ends of prostal diactins, and proximal rays of hypodermal pentactins. No choanosomal hexactins are present. There is no evidence of fusion between any spicules. Microscleres are scattered evenly throughout the choanosome. Ectosomal skeleton of the dermal side consists of abundant prostal diactins passing through the distal tangential parts of hypodermal pentactins and dermalia, which are mostly stauractins (62 % of 126 assessed), pentactins (29 %) and hexactins (10 %). The atrial ectosome lacks hypoatrial pentactins but has atrialia in the form of hexactins (89 % of 126 assessed), pentactins (8 %), stauractins, and triactins (1.5 % each). Microscleres are present as in the choanosome. Spicules. Megascleres (Fig. 3; Table 1) are prostal diactins, hypodermal pentactins, choanosomal diactins, dermalia mostly as stauractins, and atrialia mostly as hexactins. Prostal diactins (Fig. 3 A) are long bow-shaped spicules, smooth except for patches of subterminal spines; the smooth tips are rounded or parabolic; the spicule centre is not swollen. Hypodermal pentactins (Fig. 3 B) are regular and crucial in form with very long proximal rays, averaging 3.4 x tangential ray length, and fine spines evenly scattered over the entire surface. All five rays have subterminal patches of larger spines and smooth round tips. Choanosomal diactins (Fig. 3 C) are straight, bent or more commonly sinuous in shape. Most are broken so few intact spicules are measurable for length. They are smooth except for subterminal inflated rough patches; the tip is smooth and abruptly tapered to a point. The spicule centre is moderately swollen. Dermalia (Fig. 3 D) are mainly crucial stauractins completely covered with short, rounded knobs or spines; rays are tapered to a round tip. Atrialia (Fig. 3 E) are mostly hexactins ca. half of which are pinular with one ray longer than the others. Like dermalia, these are entirely covered with short, rounded knobs or spines but longer than those of the dermalia; ray tips are rounded. Microscleres (Fig. 3; Table 1) are all oxyhexasters and their variants with hemioxyhexasters being the most common. Oxyhexasters (Fig. 3 F, G) have short smooth primary rays and long straight secondary rays; the secondary rays are entirely ornamented with reclined spines that increase in size from the ray tip to its proximal end. Secondary rays on each primary ray vary from 2 - 5. Hemioxyhexasters (Fig. 3 H) are similar to oxyhexasters but at least one of the six primary rays bear only a single secondary ray. Other rare variants include oxyhexactins, oxypentasters, and oxystaurasters (Fig. 3 I).	en	Reiswig, Henry M., Dohrmann, Martin, Kelly, Michelle, Mills, Sadie, Schupp, Peter J., Woerheide, Gert (2021): Rossellid glass sponges (Porifera, Hexactinellida) from New Zealand waters, with description of one new genus and six new species.

07CBE7530CA4568993E2515A627881FA.taxon	description	Description. This description refers to New Zealand specimens only. Body forms a solitary mushroom cap-shaped upper body on a long, kinked, somewhat crooked, flattened, hollow stalk (Fig. 12 B, E). Surfaces of the upper body are smooth (Fig. 12 C, D) with a slight blunt eminence on the outer atrial face opposite the stalk insertion, but there is no indication of an osculum. The upper dermal surface lacks any visual indication of a lattice. The lower dermal surface of the specimen is divided by ridges into six depressions not seen in the smaller specimen. The stalks of both are flattened and that of the smaller bears a cylindrical central canal (Fig. 12 F). SEM views of the dried surfaces show pores in the dermal body surface membrane (Fig. 12 G), apparently contracted pores in the atrial body surface involving the atrial pinules (Fig. 12 H), and no indication of pores on the dermal stalk surface (Fig. 12 I). Dimensions of the smaller specimen upper body is ~ 12.5 x 10.6 cm in diameter; stalk is 15.9 x 9.0 mm in diameter and stalk canal is 4.1 x 3.3 mm in diameter. Length of the stalk could not be approximated. The larger specimen upper body is 25.0 x 15.9 cm in diameter while the flattened stalk is 5.9 cm wide. Measurable ostia of the smaller specimen (Fig. 12 G) are 70 and 99 µm in diameter. Texture of the body is firm but compressible; the stalk is hard. Surface of all parts are smooth, consisting of tight palisades of pinular rays of dermalia and atralia supported on hypodermal and hypoatrial pentactins. There are no projecting prostalia. Colour in life is pale pinkish brown as are the specimens preserved in ethanol. Skeleton. Choanosomal skeleton of the body consists of a tight network of choanosomal hexactins and diactins. There is no evidence of fusion between any spicules within the body. Microscleres are scattered evenly throughout the choanosome. The stalk internal skeleton is composed of large diactins oriented longitudinally and fused by synapticula. Ectosomal skeleton of the dermal and atrial sides consists of tightly packed pinular hexactins and very few pinular pentactins (1.6 % of 623 assessed). These are supported on, respectively, hypodermal and hypoatrial pentactins which are never raised above the surfaces. Microscleres are present as in the choanosome. Spicules. Megascleres (Fig. 13; Table 6) are hypodermal pentactins, choanosomal hexactins and diactins, and pinular hexactins and a few pentactins. Hypodermal pentactins of the body (Fig. 13 A) are regular and usually smooth except for spined ray ends; 8 % have indistinct spines on the proximal part of the proximal ray. The proximal rays are longer, averaging 1.24 x the length of tangential rays. Hypoatrial pentactins of the body (Fig. 13 B) are regular and spined on both ray-ends and 61 % of them on the proximal part of the proximal rays. The proximal ray is longer, averaging 1.62 x the length of tangential rays. Hypodermal pentactins of the stalk (Fig. 13 C) are regular in shape but significantly smaller than those of the body; they are spined only on ray ends. Tangential and proximal rays are approximately equal in length. Choanosomal hexactins (Fig. 13 D) are restricted to the body; rays are smooth, and spines are restricted to the ray ends except where the ray is exceptionally short. These hexactins occur in two forms, one with a short spiny ray (upper figure) and the other with all rays approximately equal in length (lower figure). Choanosomal diactins (Fig. 13 E) are straight or slightly curved and are smooth except for ends on which they have small but detectable central swellings. Dermal pinular hexactins of the body (Fig. 13 F) have bushy, nearly cylindrical pinular rays with a short, thick, rounded apical tip. Tangential and proximal rays are entirely spined and approximately similar in size and shape. Very rarely, these and pinules of other body surfaces are pentactine with only a round nub in place of the proximal ray. Atrial pinular hexactins of the body (Fig. 13 G) have pinular rays that taper in length of scales at both ray ends, resulting in fusiform shape. The pinular ray has a thick and rounded tip. Tangential and proximal rays are entirely spined and similar in size and shape. Stalk pinular hexactins (Fig. 12 H) have a pinular ray that is squat and slightly wider than those of the body spicules. Scale lengths taper basally and apically and again the apex of the pinule is a blunt, thick cap. Tangential and proximal rays are entirely spined and similar in size and shape. Microscleres (Fig. 13; Table 6) are discohexactins (43 % of 221 assessed), hemidiscohexactins (54.7 %), and discohexasters (2.3 %); all are thick-rayed forms. Discohexactins (Fig. 13 I) have rays ornamented with large, reclined spines and a terminal disc with 5 (4 - 7) marginal teeth. Hemidiscohexasters (Fig. 13 J) are similar with at least one ray being branched and at least one ray being unbranched; the total number of rays is 9.4 (7 - 13). Terminal discs are similar to discohexactins. Discohexasters (Fig. 13 K) have all primary rays branched varying from 2 - 6 terminal rays on each primary ray. Terminal discs have 3 - 8 marginal teeth.	en	Reiswig, Henry M., Dohrmann, Martin, Kelly, Michelle, Mills, Sadie, Schupp, Peter J., Woerheide, Gert (2021): Rossellid glass sponges (Porifera, Hexactinellida) from New Zealand waters, with description of one new genus and six new species.

CAA72752CEEB5252962661AFC687BFC1.taxon	description	Description. Morphology of the holotype is a compound mass of a thin, convoluted stalk-part, with at least one small mushroom-shaped body branching from it (Fig. 16 D, E), and a longer, thicker, upright stalk-part bearing a larger terminal mushroom-shaped body (Fig. 16 B, C). The larger upright stalk has six lateral knobs just below the larger body on its stalk (Fig. 16 C) whose nature and function are unknown, possibly sites for attachment to a hard substratum, or are new buds. The lower convoluted stalk part branches into many attachment points, at least eight within a 27 mm length (Fig. 16 D). The smaller of the two bodies attached to this stalk system has a felt-like cover of long pinular pentactins on the outer surface (Fig. 16 E); we have had no opportunity to examine the larger body. The stalk in all parts is hollow (Fig. 16 F). Overall dimension of the larger body in the in-situ image is 45.5 mm in diameter with the stalk having a diameter of 5.9 mm at a point 5 mm below the attachment. The smaller specimen is 5.3 mm in diameter and 3.6 mm in height. Stalk diameter varies from 1.0 mm at the short branch joining the small specimen to the convoluted stalk which is mostly ca 1.8 mm thick. The connection of the convoluted part of the stalk to the thicker upright stalk part was not available for assessment. Surfaces of the small body are covered by a villous plush of long pinular pentactins, but there are no special prostalia present. The lower convoluted stalk surfaces appear devoid of any visible surface spicules, but spicule preparations of this apparently " barren " stalk still show that typical stalk spicules are present. Thus, spicules obtained from stalks may derive from other locations on the specimen and should be considered as possibly from other original sources. Surfaces of the upper straight stalk and the terminal larger body are known only from fresh seawater-wet lab photos; they are covered by a thick spiny layer of brown tissue (Fig. 16 C). Colour of the body in life is translucent white; when preserved in ethanol it is pale brown. Skeleton. Choanosomal skeleton of the body is a network of diactins and hexactins. There is no evidence of fusion between any spicules within the body. Spicule fusion is restricted to the choanosomal diactins of the hollow stalks where the diactins are joined by fusion at spot contacts and by relatively long synapticula forming ladders. Microscleres are scattered evenly throughout the choanosome. Ectosomal skeleton of the dermal and atrial sides of the body consists of tightly packed pinular pentactins; no pinular hexactins are present. These are supported on, respectively, hypodermal and hypoatrial pentactins, which are never raised above the surfaces. Microscleres are present as in the choanosome. Spicules. Megascleres (Fig. 17; Table 9) are hypodermal and hypoatrial pentactins, choanosomal hexactins and diactins, and pinular pentactins. Hypodermal pentactins of the body (Fig. 17 A) are regular and smooth except for spined ray ends. The proximal rays are longer, averaging 1.26 x the length of tangential rays. Hypoatrial pentactins of the body (Fig. 17 B) are also regular and smooth except for spined areas on both tangential and proximal ray ends. The proximal ray is longer, averaging 1.41 x the length of tangential rays. Hypodermal pentactins of the stalk (not figured) are regular in shape but significantly smaller than those of the body. Choanosomal hexactins (Fig. 17 C) are restricted to the body; rays are smooth and spines are present only on ray ends. Macrospines are never found in the central part of these spicules. Choanosomal diactins (Fig. 17 D) are straight or slightly curved and are smooth except for the ends; they have small but detectable central swellings. Dermal pinular pentactins of the body (Fig. 17 E) have narrow pinular rays topped with a short, blunt apical spine. Their basal rays are entirely spined and end in abruptly rounded tips. Atrial pinular pentactins of the body (Fig. 17 F) have narrow pinular rays like the dermal pinules, but with a longer pinular ray (on average 1.25 x); however, presence of an apical spine was not determined since all of these examined in SEM had broken tips. Basal rays are like those of the dermal pinules. Stalk pinular pentactins (not figured) are morphologically similar to the dermal body pentactins. Microscleres (Fig. 17; Table 9) are thick-rayed discohexactins and rare hemidiscohexasters and thin-rayed stellate discohexasters. Discohexactins (Fig. 17 G) are the most abundant microscleres; they have rays ornamented with large, reclined spines and a terminal disc with 5 - 8 marginal teeth. Rare hemidiscohexasters (Fig. 17 H) are similar to the discohexactins. Thin-rayed stellate discohexasters (Fig. 17 I) have long, smooth primary rays supporting a narrow shorter brush of 3 - 9 straight, rough, terminal rays ending in small discs.	en	Reiswig, Henry M., Dohrmann, Martin, Kelly, Michelle, Mills, Sadie, Schupp, Peter J., Woerheide, Gert (2021): Rossellid glass sponges (Porifera, Hexactinellida) from New Zealand waters, with description of one new genus and six new species.

Dermalia and atrialia are pinular hexactins and / or pinular pentactins. Hypodermalia and hypoatrialia are pentactins. Microscleres are represented chiefly by spicules with discoidal terminations. They usually can be divided into two categories. The first are spicules with thick rays covered with dense spines: usually discohexactins but also discohexasters, hemidiscohexasters, and rarely discasters. The second are discohexasters with thin, smooth, or rough secondary rays usually in the form of lophodiscohexasters but sometimes calycocomes and spherical discohexasters are present among them (emended from Tabachnick 2002).	en	Reiswig, Henry M., Dohrmann, Martin, Kelly, Michelle, Mills, Sadie, Schupp, Peter J., Woerheide, Gert (2021): Rossellid glass sponges (Porifera, Hexactinellida) from New Zealand waters, with description of one new genus and six new species.

Morphology of the holotype a rhizome-like, hard, hollow, thin stem that creeps across the sediment seabed, attaching to rubble here and there, in places forming a tangled mass, from which arises the main mushroom-shaped body on a zigzag stem (Fig. 14 B, C), and two tiny, mushroom-shaped bodies (Fig. 14 D). Overall dimension of the holotype, spreading across the seabed, is 64 cm. Dimension of the larger body (Fig. 14 B) is 22.2 mm in diameter and 11.2 mm in height; its associated stalk is 3.6 (2 - 6 - 4.3) (n = 12) mm in diameter. The associated stalk measures 3.3 (2.7 - 4.0) (n = 29) mm in diameter, the length, measured in conformation from the body to the stalk tangle, is 167 mm. The smaller bodies (Fig. 14 D) are 7.2 x 5.4 and 5.2 x 4.3 mm in diameter and height, respectively; the stalk of the larger one is 1.1 (1.0 - 1.3) (n = 12) mm in diameter. The piece of thick stalk received from NIWA is 72 mm long and 3.0 (2.8 - 3.3) (n = 12) mm in diameter, approximately the same gauge as the convoluted stalk shown in the in situ and deck images. Surfaces of the body are a bit lumpy and fuzzy (Fig. 14 D); that of the thin attached stalks is also fuzzy. There are no projecting prostal spicules. Colour of the body in life is white, and the stem pale brown; when preserved in ethanol it is very pale brown, almost white. Skeleton. Choanosomal skeleton of the body is a network of diactins and hexactins. There is no evidence of fusion between any spicules within the body. Spicule fusion is restricted to the choanosomal diactins of the hollow stalks where the diactins are joined by synapticula and points of spot contacts between spicules. Microscleres are scattered evenly throughout the choanosome. Ectosomal skeleton of the dermal and atrial sides of the body and living stalks consists of tightly packed pinular pentactins and very few pinular hexactins (1.3 % of 374 assessed). These are supported on, respectively, hypodermal and hypoatrial pentactins which are never raised above the surfaces. Microscleres are present as in the choanosome. Spicules. Megascleres (Fig. 15; Table 8) are hypodermal and hypoatrial pentactins, choanosomal hexactins and diactins, and pinular pentactins and a few pinular hexactins. Hypodermal pentactins of the body (Fig. 15 A) are regular and usually smooth except for spined ray ends; 31 % have macrospines on the central part of the proximal ray. The proximal rays are longer, averaging 1.21 x the length of tangential rays. Hypoatrial pentactins of the body (Fig. 15 B) are regular and spined on both tangential and proximal ray ends; macrospines are present on the central part of most (60 %) proximal rays but all tangential rays lack macrospines. The proximal ray is longer, on average 1.86 x the length of tangential rays. Hypodermal pentactins of the stalk (Fig. 15 C) are regular in shape but significantly smaller than those of the body; they are spined on ray ends but macrospines are uncommon (12 %) on the central part of only the proximal rays. Proximal rays are generally longer, on average 1.49 x tangential ray length. Choanosomal hexactins (Fig. 15 D) are restricted to the body; rays are smooth, and spines are restricted to the ray ends. Macrospines are never found in the central part of these spicules. Choanosomal diactins (Fig. 15 E) are straight or slightly curved and are smooth except for ends; they have small but detectable central swellings. Dermal pinular pentactins of the body (Fig. 15 F) have narrow pinular rays topped with a short, sharp apical spine. Their basal rays are entirely spined and end in abruptly pointed tips. Approximately 10 % of the dermal pinules are hexactine forms. Atrial pinular pentactins of the body (Fig. 15 G) have narrow pinular rays like the dermal pinules but with a longer pinular ray (on average 2.1 x) and longer apical spine; basal rays are like those of the dermal pinules. Stalk pinular hexactins (Fig. 15 H) have a pinular ray that is narrow in its basal half but curves to one side and swells in width apically, assuming an overt club-shape. It has no atrial spine since the apex is enfolded by the apical scales. Basal rays are like those of the dermal and atrial pinules. Microscleres (Fig. 15; Table 8) are discohexactins, thick-ray discohexasters and thin-ray discohexasters. Discohexactins (Fig. 15 I) are the most abundant microscleres; they have rays ornamented with large, reclined spines and a terminal disc with 5 - 8 marginal teeth. Thick-ray discohexasters (Fig. 15 J) are the least abundant microsclere; they are spherical, have 6 - 9 thorned terminal rays on each smooth primary ray, and terminal discs have 4 - 8 marginal teeth. Thin-ray discohexasters (Fig. 15 J, K) are among the most numerous microscleres, but comparing their abundance with discohexactins is not possible since detection of the two spicule types requires different microscope arrangements. They are semi-stellate with each smooth primary ray supporting 16 (8 - 28) (n = 16) thorned terminal rays ending in discs with 3 - 7 marginal teeth.	en	Reiswig, Henry M., Dohrmann, Martin, Kelly, Michelle, Mills, Sadie, Schupp, Peter J., Woerheide, Gert (2021): Rossellid glass sponges (Porifera, Hexactinellida) from New Zealand waters, with description of one new genus and six new species.

2804D83296EF5122B2E31DAB054E9B70.taxon	diagnosis	Diagnosis. The body is usually cup-like basiphytose or lophophytose; in the pedunculate forms the body can be mushroom-like. Prostalia lateralia, when present, are formed with diactins or outwardly protruding hypodermal pentactins; prostalia basalia, when present, are outwardly protruding hypodermal pentactins which are usually specialised (anchorate). Choanosomal skeleton consists of diactins, sometimes together with less frequent hexactins. Hypodermal pentactins often present, usually they protrude from the dermal surface serving as prostalia. Hypoatrial pentactins are rarely found or absent in some taxa. Dermalia are combinations of various spicules usually pentactins; stauractins and diactins, rarely hexactins. Atrialia are usually hexactins but other holactinoidal spicules can be also found there. Microscleres are various: holactinoidal, asterous and asters; they usually have discoidal or oxyoidal terminations but sometimes floricoidal, onychoidal, or sigmoidal ones (after Tabachnick 2002).	en	Reiswig, Henry M., Dohrmann, Martin, Kelly, Michelle, Mills, Sadie, Schupp, Peter J., Woerheide, Gert (2021): Rossellid glass sponges (Porifera, Hexactinellida) from New Zealand waters, with description of one new genus and six new species.

BD8B043A48B9551BAEB1EEE18E9F7785.taxon	description	Description. Morphology of the holotype body is a thick-walled tubular sponge, attached to hard substratum, by a moderately long, narrow stalk (Fig. 6 B, C). A moderately sized, round osculum is terminal and opens into a deep atrial cavity. The margin is blunt, bordered by a band of diactine marginalia (Fig. 6 D, F). The dermal surface has a dense covering of raised, prostal, hypodermal pentactins (Fig. 6 D, E), projecting up to 7 mm from the surface proper. Some of the deck images indicate long diactins projecting sparsely, up to 14 mm, from the dermal surface, but these may be foreign in origin; we have not found such large diactins in the material available for examination. Dimensions of the holotype are ~ 6 cm in total length, including the stalk of 1.8 cm length (Fig. 6 G), and 3.5 cm in width; the maximum body wall thickness is 13.9 mm. The osculum is 12.3 by 16.9 mm diameter in situ. Texture is soft, compressible, and resilient, neither hard nor fragile. Surface of the dermal side below the layer of projecting hypodermal pentactins is supported by an intact tight lattice of dermalia (Fig. 6 H). The atrial surface (Fig. 6 I), in contrast, is torn apart by removal from supporting fluids and the atrial lattice remains only as dismembered patches attached to underlying diactins. Colour in life is pale brown as is the specimen preserved in ethanol. Skeleton. Choanosomal skeleton consists of a loose, vacuolar network of thin choanosomal diactins, large choanosomal hexactins and the thicker proximal rays of the hypodermal pentactins. There is no evidence of fusion between any spicules. Microscleres are scattered evenly throughout the choanosome. Ectosomal skeleton of the dermal side consists of abundant prostal pentactins providing good support for the sturdy lattice of stauractine (60.0 % of 315 assessed), pentactine (38.4 %), and rare hexactine (1.64 %) dermalia. The atrial ectosome lacks hypoatrial pentactins but has bands of diactins that provide poor support for the atrial lattice of mainly hexactins (86.4 % of 118 assessed), pentactins (7.5 %), and stauractins (5.1 %). Microscleres are present as in the choanosome. Spicules. Megascleres (Fig. 7; Table 3) are prostal hypodermal pentactins, marginal diactins, choanosomal diactins of the body, choanosomal diactins of the stalk, dermalia and atrialia. Prostal hypodermal pentactins (Fig. 7 A) are large, raised orthotropal forms with long straight tangential rays. Tangential rays are ca. one half the length of the longer straight proximal rays. The spicules are smooth except for the rough sharp or round tips. Marginalia (Fig. 7 B) are long, slightly curved diactins; no intact tips were found in SEM surveys but an exhaustive survey with LM indicates tips taper to nearly invisible thinness and are quite distinct from the thick roughened tips of choanosomal diactins. Choanosomal diactins (Fig. 7 C) are straight or slightly curved with undetectable central swellings; they are smooth except for the rough, slightly inflated tips. Stalk diactins (Fig. 7 D) are longer and thicker than the choanosomal diactins, but otherwise similar. Dermalia (Fig. 7 E) are mainly entirely rough stauractins and pentactins with rounded ray tips. Atrialia (Fig. 7 F) are entirely rough hexactins with equal length rays and more acute ray tips. Microscleres (Fig. 7; Table 3) are oxyhexasters, hemioxyhexasters, and anisodiscohexasters. Oxyhexasters (Fig. 7 G) and hemioxyhexasters have very short, sparsely spined or smooth, thick primary rays, ending in swollen hemispheres; 1 - 7, usually 3 - 4, rough, straight, terminal rays tapering to pointed tips emanate from the margins and occasionally from the centre of the hemisphere. Short to very short spur-like terminal rays are common. Anisodiscohexasters (Fig. 7 H) have smooth primary rays ending in ovoid strobila. Each strobilum supports ca. 20 - 30 rough, curved terminal rays that end in discs with 4 - 7 marginal discs. The tuft of terminal rays from each primary ray varies in length of rays, and with ray length the diameter of terminal discs, in a pattern that is not yet clear, but the whole spicule resembles a radially symmetrical starburst.	en	Reiswig, Henry M., Dohrmann, Martin, Kelly, Michelle, Mills, Sadie, Schupp, Peter J., Woerheide, Gert (2021): Rossellid glass sponges (Porifera, Hexactinellida) from New Zealand waters, with description of one new genus and six new species.

D0CFA768826F5F16B8404AB1356975B9.taxon	description	Description. Morphology of the holotype and paratype a thick-walled, tubular sponge, attached to hard substratum by a narrow base (Fig. 4 B). A round osculum of moderate size is terminal and opens into a deep atrial cavity. The margin is sharp and there are indications of sparse diactin marginalia in deck images, but we have been unable to verify them in the material at hand. The dermal surface has a dense covering of raised, prostal, hypodermal pentactins (Fig. 4 C, D, I) projecting up to 1 cm from the surface proper. There is indication in some of the deck images of long diactins projecting sparsely up to 6 cm from the dermal surface, especially basally, but these may be choanosomal diactins pulled out during collection; we have not found such large diactins in the material we had for examination. Dimensions of the holotype are ~ 13.3 cm high, 7.0 cm wide, and 10.8 (9.2 - 13.3) (n = 9) mm in body wall thickness; the osculum is 2.2 cm in diameter in situ. The paratype is 19.5 cm high, 13.4 cm wide, and body wall is 7.4 (5.5 - 9.3) (n = 11) mm in thickness. The osculum is 4.2 cm in diameter in situ. Texture is soft, compressible, and resilient, neither hard nor fragile. Surface of the dermal side is covered by a thick layer of projecting hypodermal pentactins (Fig. 4 E). The dermal lattice is torn apart, and dermalia reside in preserved specimens as attached flakes on the hypodermalia (Fig. 4 G). The atrial layer retains the atrial lattice covering smaller apertures (Fig. 4 F, H); no large megascleres project into the atrium. Colour in life is transparent white, preserved in ethanol is medium brown (Fig. 4 C). Skeleton. Choanosomal skeleton consists of a loose, vacuolar network of thin choanosomal diactins, large choanosomal hexactins, and the thicker proximal rays of the hypodermal pentactins. There is no evidence of fusion between any spicules. Microscleres are scattered evenly throughout the choanosome. Ectosomal skeleton of the dermal side consists of abundant prostal pentactins supporting a delicate lattice of hexactine, pentactine, and stauractine dermalia. The atrial ectosome lacks hypoatrial pentactins but has bands of diactins that support the atrial lattice of hexactins, providing greater support than available to the dermal lattice. Microscleres are present as in the choanosome. Spicules. Megascleres (Fig. 5; Table 2) are prostal hypodermal pentactins, choanosomal diactins, choanosomal hexactins, dermalia, and atrialia. Prostal hypodermal pentactins (Fig. 5 A) are mostly large, raised paratropal forms (90 % of 68 scored) with long, very curved tangential rays, but some regular, crucial forms occur (10 %) in smaller forms especially near the margin. Tangential rays are 1.7 x the shorter, straighter proximal rays. The spicules are smooth except for the rough sharp tips. Choanosomal diactins (Fig. 5 B) are straight or strongly curved, usually with undetectable central swellings; they are smooth except for the rough, slightly inflated tips. Choanosomal hexactins (Fig. 5 C) are large forms with strongly curved or nearly straight, nearly equal length rays, which are otherwise similar to those of the hypodermalia. Dermalia (Fig. 5 D) are entirely spined and consist of stauractins (31 % of 387 scored) and similar forms with reduced fifth ray (subpentactins) or both fifth and sixth rays in one axis (subhexactins) (64 %) with a few (1 - 2 %) as tauactins, diactins and paratetractins. It was not possible to differentiate the subpentactins and subhexactins either wet in dishes or mounted spicule microscope slides. Tips are either rounded or more often sharp. Atrialia (Fig. 5 E) are entirely spined and mostly subhexactins (71 % of 125 scored) with one ray reduced or hexactins (26 %) with all rays of nearly equal length; a few (1 - 2 %) are stauractins and tauactins. Ray tips are sharp-pointed. Microscleres (Fig. 5; Table 2) are oxyhexasters and their variants, with hemioxyhexasters being the most common, and anisodiscohexasters. Oxyhexasters and hemioxyhexasters (Fig. 5 F, G) have very short smooth primary rays and long straight secondary rays entirely ornamented with small, reclined spines. Secondary rays on each primary ray vary from 1 - 4. Anisodiscohexasters (Fig. 5 H) are spherical with stellate discs with 4 - 6 marginal claws on the ends of terminal rays. Primary rays are smooth and end in strobiloid discs with a short central projecting knob. Each primary strobilum supports 30 - 40 terminal rays with undulating, probably helically coiled, finely rough shafts of unequal lengths. Terminal discs vary in diameter with shaft length, the longer shafts carrying the larger discs, e. g., a series 1.7, 2.5, 3.1, 3.4, 3.6, 5.4, 6.9 µm diameter for shafts 15.0, 20.5, 23.5, 27.3, 32.0. 33.4, 37.1 µm in length. These spicules look very different in LM (lower image) and SEM (upper image) due to collapse of the rays during drying for SEM and support of them by balsam in LM.	en	Reiswig, Henry M., Dohrmann, Martin, Kelly, Michelle, Mills, Sadie, Schupp, Peter J., Woerheide, Gert (2021): Rossellid glass sponges (Porifera, Hexactinellida) from New Zealand waters, with description of one new genus and six new species.

44B4A7D7A3735F1C8A3E1ABDD7800305.taxon	description	Description. Body form is a heavy-looking, thick-walled, club-shaped, pendant sponge with a narrow basal attachment, widening gradually to a hemispherical rounded terminal end (Fig. 8 B, C) where a large osculum is centrally located. The osculum opens into a deep atrial cavity (Fig. 8 D). The margin is sharp-edged with indication of sparse marginalia that do not differ from prostal diactins of the lower body. The external surface of the upper body is fairly smooth, without prostalia, but the lower half is conspicuously conulose with long prostal diactins projecting in small groups from conules (Fig. 8 E). We did not have access to the basal attachment so we cannot comment on the basidictyonalia. Dimensions of the specimen are 27.6 cm in height, 11.7 cm in maximum width, 5.7 - 10.9 cm in diameters of the osculum, 10.0 mm in maximum wall thickness, 8.3 mm in length of projecting part of prostal diactins. Texture is firm but compressible and resilient, neither soft nor fragile. Surface of the dermal side is covered by an intact lattice of dermalia (Fig. 8 G) consisting mostly of pentactins (98 % of 302 assayed), and a few stauractins and diactins (1 % each). The upper body surface is fairly smooth, but the lower body is covered with conspicuous conules up to 3.2 mm high, from which prostal diactins project in small groups of one to four. One large pentactin was found but it was broken and assumed to be foreign. The atrial surface is covered by a felt-like layer of disarranged atrialia (Fig. 8 H) composed of hexactins (57 % of 168 assayed), pentactins (20 %), paratetractins (8 %), diactins (6 %), stauractins (5 %), and triactins (3 %). Colour in life is very pale brown, preserved in ethanol is medium brown. Skeleton. Choanosomal skeleton consists of a tight series of macroscopic partitions of inhalant and exhalant channels running perpendicular to the body surfaces (Fig. 8 F). They consist of networks of choanosomal diactins and microscleres and in the lower body the proximal ends of the prostal diactins. A few small patches of fused choanosomal diactins occur but these are too rare to provide significant support to the body. Ectosomal skeleton of the dermal side consists of the robust lattice of pentactine dermalia and in the lower body the projecting prostal diactins. The atrial ectosomal skeleton consists of the felt-like lattice of atrialia and the supporting layer of hypoatrial diactins. Spicules. Megascleres (Fig. 9; Table 4) are prostal diactins, choanosomal diactins, dermalia, and atrialia. Prostal diactins (Fig. 9 A) are large, curved, and smooth spicules with rounded proximal tips either smooth or bearing very low suggestions of obsolete spines. They have neither an axial cross nor central swellings. Distal tips are invariably broken off. Choanosomal diactins (Fig. 9 B) come in three distinct forms. The larger ones over 2 mm long are straight or slightly curved or sinuous and are smooth except for the patches of spines at the rounded or abruptly pointed tips. Those between 1 and 2 mm long have sharp tips and longer spines on the tip patches. The shortest, less than 1 mm long, are entirely spined with sharp tips and often with a central tyle or four knobs. Dermalia (Fig. 9 C) are thick stubby pentactins, entirely profusely spined without a knob of a sixth ray. Atralia (Fig. 9 D) are highly diverse; the most common hexactins have thinner and less densely spined rays than the dermalia. Pentactin atrialia are very similar to the dermal pentactins but have a knob in place of the sixth ray. Paratropal atrialia have rays similar to the hexactine atrialia. Spheres (Fig. 9 E) are common and here considered megascleres. Microscleres (Fig. 9; Table 4) are two types of discohexasters and one type of oxyhexaster and its variants, rare hemioxyhexasters and oxyhexactins. Discohexasters 1 (Fig. 9 F) are spherical with very short smooth primary rays, each supporting 3.5 (2 - 5) thick secondary rays ornamented with reclined spines. Terminal discs invariably have six stout marginal teeth. Discohexasters 2 (Fig. 9 G) are smaller spherical forms with each smooth primary ray supporting 6.3 (5 - 8) thinner terminal rays; the terminal discs also invariably have 6 marginal teeth. Oxyhexasters (Fig. 9 H) are stout spherical forms with each short smooth primary ray supporting 3.2 (3 - 5) fully developed secondary rays ornamented with dense reclined spines and ending in sharp tips. Each oxyhexaster also has 2 - 12 poorly developed secondary rays only a few micrometres in length. Only one hemioxyhexaster and three oxyhexactins, all of a similar size and ray characters as the oxyhexaster, were discovered in microsclere surveys.	en	Reiswig, Henry M., Dohrmann, Martin, Kelly, Michelle, Mills, Sadie, Schupp, Peter J., Woerheide, Gert (2021): Rossellid glass sponges (Porifera, Hexactinellida) from New Zealand waters, with description of one new genus and six new species.

0984F0D27E075AFAA164DCFAC8FF3BB2.taxon	description	Description. Morphology of the holotype and paratype is a thick-walled, club-shaped sponge with a narrow basal attachment, widening gradually to a hemispherical rounded terminal end where a large osculum is centrally located (Fig. 10 B-E). The osculum opens into a deep atrial cavity. The margin is sharp-edged with indication of sparse marginalia that do not differ from prostal diactins of the general body wall. The external surface of the entire body is clean and conulose, with prostal diactins and hypodermal pentactins emanating from conules in small groups of 1 - 10. Dimensions of the holotype and paratype are, respectively, length 16.5 and 15.8 cm, width 9.5 and, excluding the lateral bulge, 9.5 cm, diameter of the osculum 6.4 and 6.6 cm, wall thickness 11.1 and 10.0 mm. Texture is soft, compressible, and resilient, but not fragile. Surface of the dermal side is conulose and bears a layer of prostal diactins projecting 12.5 (6.5 - 19.3) (n = 9) mm above the dermal surface, intermingled with a veil of prostal, hypodermal, thorned, paratropal pentactins (Fig. 10 F, G) projecting 8.6 (7.2 - 10.0) (n = 9) mm above the surface. On the surface below is a lattice of overlapping dermalia of mostly pentactins (94 % and 82 % of 160 and 101 assessed) (Fig. 10 H). The atrial surface bears a poorly preserved atrial lattice of mostly hexactins (94.7 % and 94 % of 133 and 131 assessed) (Fig. 10 I) forming a cover over the exhalant apertures. Colour in life and preserved is very pale brown. Skeleton. Choanosomal skeleton is composed of choanosomal diactins without detectable macroscopic or microscopic organisation. No evidence of spicule fusion was noted in either specimen. Microscleres are scattered throughout the choanosome. Ectosomal skeleton of the dermal side consists of the prostal diactins and projecting veil of thorned pentactins. The dermal surface is covered by a robust lattice of mostly pentactine dermalia. The atrial ectosome consists of the felt-like disorganised lattice of mostly hexactine atrialia and the supporting layer of hypoatrial diactins. Spicules. Megascleres (Fig. 11; Table 5) are prostal diactins, prostal hypodermal pentactins, choanosomal diactins, dermalia, and atrialia. Prostal diactins (Fig. 11 A) are large, curved, and smooth spicules with rough subterminal patches and round tips. They have neither axial crosses nor central swellings. Prostal hypodermal pentactins (Fig. 11 B) are large spicules with proximal rays ~ 1.4 times the length of tangential rays; the tangential rays are mainly paratropal, occasionally orthotropal. Both tangential and proximal rays have smooth rounded tips, but only tangential rays bear large thorns on the middle halves of the rays. Choanosomal diactins (Fig. 11 C) occur in two distinct forms. Large ones> 2 mm in length are straight, slightly curved or sinuous, and are smooth except for rough subterminal areas; tips are rounded or abruptly pointed. Small forms <2 mm in length are entirely spined, have sharp tips and often four central knobs or a single tyle. Dermalia (Fig. 11 D) are thick stubby pentactins, entirely and profusely spined without a knob of a sixth ray. Atralia (Fig. 11 D) are most commonly hexactins, with rays longer, thinner, and less profusely spined than those of dermalia. Microscleres (Fig. 11; Table 5) are three types of discohexasters and two types of oxyhexasters and their variants, rare hemioxyhexasters and oxyhexactins. The centrum in all categories tends to be varyingly swollen to the extent that the spicules approach asteroid forms. The oxyhexasters are extremely difficult to separate into types due to presence of intermediates. Discohexasters 1 (Fig. 11 F) are semi-stellate with very short smooth primary rays, each supporting 4 - 8 gently curved secondary rays ornamented with reclined spines; terminal discs invariably have eight stout marginal teeth. Discohexasters 2 (Fig. 11 G) are very slightly smaller spherical forms with each smooth primary ray supporting 2 - 4 straight thick terminal rays ornamented with reclined spines; the terminal discs have 5 - 9 marginal teeth. Discohexasters 3 (Fig. 11 H) are small semi-stellate forms like discohexasters 1, with very short, smooth primary rays, each supporting 7 - 11 thin, curved, rough secondary rays, each ending in a terminal disc with 4 - 9 marginal teeth. Oxyhexasters 1, including hemioxyhexasters (Fig. 11 H), are stout spherical forms with each short smooth primary ray supporting 1 - 3 secondary rays ornamented with dense reclined spines and ending in sharp tips. Oxyhexasters 2 (no SEM image available) are forms with very thin secondary rays and often broken; they have diverse characters but are not considered immature forms of oxyhexasters 1. The centres are very small or swollen to globular form and the distal ends of the primary rays are either very thin or globular, each primary end supports two or three thin secondary rays that appear totally smooth. We are not confident in recognising this as a spicule category since the only practical character in defining it is the thinness of the secondary rays and size. Oxyhexactins (no SEM available) are rare: only four have been verified in spicule surveys. They have characteristics of oxyhexasters 1 in the stoutness and ornamentation of their rays.	en	Reiswig, Henry M., Dohrmann, Martin, Kelly, Michelle, Mills, Sadie, Schupp, Peter J., Woerheide, Gert (2021): Rossellid glass sponges (Porifera, Hexactinellida) from New Zealand waters, with description of one new genus and six new species.
