Pseudoloricella Ashby, 1925: 198; Componochiton Milne, 1963: 25; Sinolorica Xu, 1990: 376. Genus distribution. Sagami Bay and Omurodashi Bank (Japan), South of East China Sea, north of South China Sea, Indonesia, New Guinea, Solomon Islands, Tonga Islands, New Caledonia, South and East Australia, Tasmania and New Zealand, intertidal – 772 m. Miocene – Recent. The inclusion of the genus Squamophora Nierstrasz, 1905 as a junior synonym of the genus Loricella (Van Belle 1978, 1983) led to a confusion of generic characters of Loricella. The restoration of the genus Squamophora (Sirenko 2021) makes an emendation of the diagnosis of the genus Loricella necessary:	en	Sirenko, Boris (2021): Composition of the genus Loricella (Mollusca: Polyplacophora: Loricidae) and the description of two new species.

82770F72FF9428792BE1FAA0746C8D34.taxon	diagnosis	Diagnosis. Small to large sized, ovoid and broadened anteriorly; head valve large about more than twice as wide as tail valve, intermediate valves short and wide, tail valve with sinus and usually several indistinct slits, mucro terminal. Tegmentum of all species except for old specimens of L. angasi has numerous pits, which are arranged mainly in radial rows on the head valve and lateral areas and in longitudinal rows on central areas. There is a row of larger and deeper pits on each diagonal between central and lateral areas of the tegmentum in deep-water species. Pores of aesthetes are numerous on surface of tegmentum between the pits. The jugal plate is usually well developed and often separated from the apophyses by a notch, on the intermediate valves it is wide, and on the tale valve it is narrow, tooth-shaped. Slit formula 8 – 20 / 1 – (rare 2) / sinus + 2 – 8 obsolete. Narrow mantle fold and wide head. Posterior slit in girdle is present or absent. Girdle, dorsally covered with small scales with tubular hollow and rare tufts of bristles. The tufts are located on the perinotum closer to the outer margin. There are rare single scattered bristles. The hyponotum scales are elongate, rectangular and smooth. There are 14 – 27 gills on each side arranged from valve II or III to valve VII or VIII. Radula 1.6 – 4.1 mm long with 28 – 45 transverse rows of mature teeth in chitons of BL 9.0 – 26.0 mm. Central tooth of radula short, bulbous, first lateral tooth slender, with small cusp at top, head of major lateral tooth bicuspid, major uncinal tooth with rather wide blade.	en	Sirenko, Boris (2021): Composition of the genus Loricella (Mollusca: Polyplacophora: Loricidae) and the description of two new species.

82770F72FF9A28692BE1FA50746A8EF8.taxon	description	Description. Holotype with BL 16.0 mm long. Valves thin, carinated, moderately elevated (dorsal elevation in valve V 0.36), hardly beaked. Lateral areas distinctly raised, side slope slightly convex. Color of tegmentum yellowish with pale brown spots. Head valve semicircular, much wider than tail valve, anterior margin distinctly lobate, posterior margin widely V-shaped, sculptured with 12 elevated slightly nodulose radial ribs. Intermediate valves broadly rectangular, with front margin concave at both sides of a anteriorly produced (especially in valve II), almost semicircular jugal part, lateral areas slightly raised, separated from central area by nodulose radial rib. Tail valve small, triangular, without caudal notch, and with very short, tucked down postmucronal area, antemucronal area straight, mucro terminal. Tegmentum of head valve, lateral areas and postmucronal area with numerous small pits arranged in a random manner. Central area of intermediate valves and antemucronal area of tail valve with numerous pits arranged partly in a random manner, partly in short longitudinal rows. Articulamentum white, apophyses very wide, rather short, connected across the narrow sinus by a short, concave jugal plate notched at the sides. Jugal plates with 5 teeth in valve II, and bilobed in other intermediate valves, insertion plates short, slit formula 10 / 1 (rare 2) / sinus + 2 obsolete, valve IV with two slits in right side, other intermediate valves with one slit per side, slit rays distinctly visible as rows of minute transverse grooves, teeth sharp, strongly pectinated, eaves narrow, finely porous. Girdle yellowish white with light brown transverse bands, relatively narrow, slightly broadening anteriorly, covered dorsally with small, short, imbricating, bent scales 110 – 140 x 75 – 105 μm, ornamented with small granules or sometimes grooves on top. Atiny canal penetrates the body of each scale from top to base. Opposite the sutures and around the head valve are a row of rare (1 – 2) horny bristles up to 800 µm long, some of which still bear a minute, calcareous, sharp-pointed, terminal spicule, 90 – 100 μm long. There is a narrow, deep median slit in the girdle, just behind the sinus in the tail valve. Marginal spicules are of two types: long, narrow spicules 100 x 15 μm with feather-like ribs and flattened, sharply pointed spicules 34 – 51 x 10 μm.

82770F72FF9A28692BE1FA50746A8EF8.taxon	discussion	Remarks. Loricella neoguinensis n. sp. is similar to L. vanbellei in its ribs on the head valve and dorsal scales and marginal spicules, but differs from the latter in having pits arranged in a random manner on the head valve and lateral areas (vs pits arranged in radial rows in L. vanbellei), insertion plates are strongly pectinated (vs smooth in L. vanbellei), a sharpened hind margin of the tail valve (vs obtusely angular in L. vanbellei), a very short postmucronal area, and the ratio of the length of the antemucronal area to the length of the postmucronal area of 6.6 (vs 2.3 – 3.6 in Loricella vanbellei). The new species has similar pectinated insertion plates like the shallow water species L. angasi but differs from other deep-sea species of Loricella by having strongly pectinated insertion plates and pits that are arranged in a random manner on the head valve and lateral areas.	en	Sirenko, Boris (2021): Composition of the genus Loricella (Mollusca: Polyplacophora: Loricidae) and the description of two new species.

82770F72FF86286D2BE1FA6374388FD0.taxon	description	Description. Chiton of medium size, body length of holotype 28 mm and width 19 mm, ovoid, depressed (dorsal elevation about 0.25), valves carinate, easily broken. Tegmentum white with thin dirty brown deposits. Head valve wide, semicircular, without radial ribs. Intermediate valve rectangular, not beaked, anterior margin convex, posterior margin straight, lateral areas slightly raised, separated from central area by a flattened radial rib. Tail valve small, narrower than head valve, antemucronal slope slightly concave, mucro terminal, postmucronal area short (ratio of length of antemucronal area to length of postmucronal area 3.1). Tegmentum of head valve, lateral areas of intermediate valves and postmucronal area of head valve with numerous small pits arranged in a random manner. Central area of intermediate valves and antemucronal area of tail valve with numerous pits arranged mainly in a longitudinal rows but partly in a random manner. There are several slightly pronounced growth lines in all areas. Articulamentum white, thin, apophyses very wide, rather short with short jugal plate bilobed in intermediate valves, insertion plates short, slightly pectinated, slit formula c. 12 / 1 / sinus + 6 obsolete, eaves narrow, finely porous. Girdle dirty brown because of deposits, narrow, about 2.0 mm in width near valve VI, covered dorsally with small, short, imbricating, bent scales 80 – 90 x 100 – 64 μm, ornamented with small granules on top. Atiny canal penetrates the body of each scale from top to base. Opposite the sutures and around the head valve is a row of horny bristles up to 250 µm long, some of which bear a minute, calcareous, sharp-pointed, terminal spicule, 50 x 14 μm. Marginal spicules 72 x 16 μm slightly curved, sharply pointed and with three indistinct riblets on upper half. Ventrally, the girdle is covered with several rows of rectangular, obtusely pointed scales (60 x 31 μm) near the margin and longer rectangular, obtusely pointed scales (100 x 17 μm) in the middle of hyponotum. Central tooth of radula short with a narrow, convex blade. First lateral tooth slender, the base excavated, distally abruptly broadening to knobby outgrowths on both sides, major lateral tooth with wide bicuspid head. The holotype has 20 gills on each side extending from valve III to valve VII, nephridiopore and gonopore arranged between 4 – 5 and 5 – 6 gills accordingly counted from the last one.	en	Sirenko, Boris (2021): Composition of the genus Loricella (Mollusca: Polyplacophora: Loricidae) and the description of two new species.

82770F72FF86286D2BE1FA6374388FD0.taxon	discussion	Remarks. Loricella solomonensis n. sp. differs from other members of the genus by having granules on the dorsal scales, and the pits on the tegmentum of the head valve and lateral areas of intermediate valves arranged in a random manner (vs pits arranged in radial rows in all other species except for L. neoguinensis n. sp.). L. solomonensis n. sp. differs from L. neoguinensis n. sp. by the absence of radial ribs on the head valve (vs radial ribs on the head valve in L. neoguinensis n. sp.), a longer postmucronal area (vs very short postmucronal area in L. neoguinensis n. sp.) and a small caudal notch (vs caudal notch is absent in L. neoguinensis n. sp.). The new species differs from L. scissurata by having the characters mentioned above and by having small caudal notch (vs wide caudal notch in L. scissurata) and longer antemucronal area of the tail valve.	en	Sirenko, Boris (2021): Composition of the genus Loricella (Mollusca: Polyplacophora: Loricidae) and the description of two new species.
