03D63555CC0F0D4751BEFE12BAC86165.taxon	diagnosis	Modified diagnosis Scalpellomorphs that possess a maximum of 14 plates (carina, rostrum, paired scuta, terga, upper latera, carinolatera, rostrolatera, and inferior median latera), rarely 13, by secondary loss of the rostrum. Remarks This definition works effectively for all known living and fossil forms, with the exception of the highly derived Scalpellopsis striatociliata Broch, 1922. The record of a subcarina in the Cretaceous species Diotascalpellum fossula (Darwin, 1851 b) by Hébert (1855) and Withers (1935) is not substantiated by a re-examination of the material. The family appears in the Aptian (Early Cretaceous, about 120 Mya), and is represented by abundant fossil and living forms. In the Cretaceous and the Palaeogene, species were common in shallow and deep marine environments, with palaeodepths of as little as 20 – 30 m. Neogene and present-day records are almost exclusively from the deep sea. The present study identifies two groups, which are taken as subfamilies.	en	Gale, Andrew Scott (2016): Phylogeny of the deep-sea cirripede family Scalpellidae (Crustacea, Thoracica) based on shell capitular plate morphology.

03D63555CC0F0D4651A0FB7EBE34645E.taxon	discussion	Remarks This definition of Scalpellinae differs in major respects from that of Zevina (1978 a), for whom the family was characterized by the subapical carinal umbo, the inflexed carina, and the subapical umbones of the upper and inframedian latus; however, the group as thus defined is polyphyletic (see above), and these features evolved independently a number of times within the Scalpellidae. The subfamily is therefore rediagnosed to include the basal group of scalpellids shown in Figure 14, which are technically paraphyletic, but can be readily identified.	en	Gale, Andrew Scott (2016): Phylogeny of the deep-sea cirripede family Scalpellidae (Crustacea, Thoracica) based on shell capitular plate morphology.

03D63555CC310D7952DAFBD8BB776301.taxon	discussion	Remarks Foster (1980: 526) established Graviscalpellum to include ‘ Arcoscalpellids that are hermaphroditic, attain relatively large size and have lower latera about one tenth the height of the capitulum’. Subsequently, the genus was treated as a junior synonym of Anguloscalpellum Zevina, 1978 b, because Zevina (1981) had included S. pedunculatum in that genus (e. g. Young, 2007); however, the type species of Anguloscalpellum, Scalpellum angulare Nilsson-Cantell, 1930, falls within the genus Weltnerium as redefined in this paper (trapezoidal scutum; deep, transversely elongated receptacle for dwarf male; rostrum with broad triangular external surface), and is evidently not related closely to S. pedunculatum. Therefore, Graviscalpellum is resurrected from synonomy to include both the extant G. regina (Pilsbry, 1907) and a number of fossil species from the Oligocene – Miocene of New Zealand (Buckeridge, 1983). The molecular phylogeny of Lin et al. (2015: fig. 3) shows G. regina and G. pedunculatum as closly related taxa.	en	Gale, Andrew Scott (2016): Phylogeny of the deep-sea cirripede family Scalpellidae (Crustacea, Thoracica) based on shell capitular plate morphology.

03D63555CC310D7851B6F9E5BDD766FD.taxon	discussion	Remarks The name Arcoscalpellum was formerly applied to most living and many fossil scalpellids (Withers, 1935, 1953; Newman et al., 1969). After the revisions of Zevina (1978 a, b, 1981), the genus was used in a restricted sense and identified by the ‘ inframedian latus triangular, reaching upper latus, umbo apical’ (Shalaeva & Boxshall, 2014: 21). This condition is shown here to be plesiomorphic for scalpellids, and the genus is therefore redefined with reference to the morphology of the type species, Arcoscalpellum michelottianum. It encompasses a small group of more derived Scalpellinae (e. g. Fig. 2 C, D) in which the carinolatus is in possession of a carinal margin and an upper latus surface (Fig. 10 L, M). It ranges from the Eocene to the present day. AMIGDOSCALPELLINAE SUBFAM.

The distinctive radial sculpture is also present, albeit in a weaker and more restrict- ed form, on some fully grown individuals of a few species of Catherinum (e. g. Ca. australicum, Ca. recurvitergum, and Ca. striolatum; see Young, 1998). These can, however, always be distinguished on the basis of the morphology of the inframedian latus and the overlap of the scutum by the upper latus. Note that the genus as here defined also includes some taxa traditionally referred to Arcoscalpellum (such as Arcoscalpellum truncatum), which fall naturally in Amigdoscalpellum.	en	Gale, Andrew Scott (2016): Phylogeny of the deep-sea cirripede family Scalpellidae (Crustacea, Thoracica) based on shell capitular plate morphology.

As noted by Young (2007), Catherinum fall into several distinct morphological groups. Although not dealt with here, many of the taxa assigned to Annandaleum (e. g. with strikingly reduced plates, such as Annandaleum japonicum Hoek, 1883), have an hourglass-shaped inferior median latus, at least in the juvenile stages, and are likely to be derived from species of Catherinum by plate reduction. Planoscalpellum Zevina, 1978 b is a Catherinum- like form in which the upper latus umbo is unusually low on the scutum.	en	Gale, Andrew Scott (2016): Phylogeny of the deep-sea cirripede family Scalpellidae (Crustacea, Thoracica) based on shell capitular plate morphology.

03D63555CC320D7A5324FD25BA79602A.taxon	description	FIGURE 19 C – K, N – Q, T, V Diagnosis Catherinum in which the occludent margin of the tergum is straight, and the external surface adjacent to this carries three ribs that diverge from the umbo. The upper part of the upper latus margin of the scutum is embayed. The carinolatus has a very broad upper latus margin. Derivation of name After East Anglia, in which the type material was collected. Material Fifty valves, including carinae, scuta, terga, and carinolatera, from the upper Campanian, Belemnitella mucronata zone chalk of Keswick and Cringleford Newfound Farm pits, Norwich, Norfolk, UK. The scutum illustrated is the holotype (Figure 19 O), and the other illustrated valves are paratypes. Description The carina (Fig. 19 E, I, P, T, V) is gently incurved towards the tergum, and the parietes are of even width; intraparietes are not developed. The tectal ridges are robust and broad (Fig. 19 E, T), and the tectal surface between these is slightly convex. The tergum (Fig. 19 Q) is elongated and triangular, and the carinal margin is slightly convex. Three radial ridges run from the umbo, subparallel with the occludent margin. The scuta (Fig. 19 J, K, N, O) are concavo – convex, trapezoidal, and the umbo is pointed and incurved; the upper latus margin has a distinctive concavity just beneath the tergal – upper latus angle. A narrow groove runs parallel with the occludent margin. On the interior of the valve, a deep, oval dwarf male receptacle lies between the apex and the scutal adductor scar. The carinolatus (Fig. 19 C, D, F – H) has a low, incurved umbo, and a tall carinal margin. The long, straight upper latus and inframedian latus margins are set at right angles. The plate is very typical of Catherinum of the Ca. hispidum (Fig. 19 A, B) and Ca. striolatum (Fig. 7 P, Q) type. Remarks Catherinum anglicum sp. nov. is perhaps closest to the extant Ca. hispidum from the Norwegian Sea. The carinae are very similar indeed, both carrying very broad, robust tectal ridges (Fig. 19 I, S, T), and with shallow short grooves for articulation with the carinolatus in the interior (Fig. 19 U, V). The terga are similar in shape, but the scutal margin is convex in Ca. hispidum and straight in Ca. anglicum sp. nov. Three divergent ribs run from the umbo, adjacent to the occludent margin in Ca. anglicum sp. nov., but these are absent in the living species (Fig. 19 Q, R). The scuta both possess an incurved umbo, and a large, deep pit for dwarf males (Fig. 19 J – O), which is directed slightly more transversely in Ca. hispidum. The carinolatera are similar in shape (Fig. 19 A – D, F – H), but the tergal margin is longer in Ca. anglicum sp. nov. It can be distinguished from small carinae of Diotascalpellum fossula by the absence of intraparietes. A further undescribed species of Catherinum is present in the Norwich chalk assemblage; this will be named subsequently. This is a very small species: the scuta have a maximum height of 2 mm, and the total height of the individuals was probably not more than 5 mm. It was possibly attached to living crustaceans or pycnogonids, by analogy with the small extant species Weltnerium nymphocola (Hoek, 1883) and Verum brachiumcancri Weltner (see Buhl-Mortensen & Høeg, 2012).	en	Gale, Andrew Scott (2016): Phylogeny of the deep-sea cirripede family Scalpellidae (Crustacea, Thoracica) based on shell capitular plate morphology.
