714BE3B3DC635B99A07A482FC7B33BAE.taxon	description	Description. The shape of the species is elongate oval, usually with an angular frontal margin. There is a central dorsal hump and a broad mantle skirt. The black markings are smooth, loosely paired in a series of four or five polygons, with a larger central one just in front of the gills. Each rhinophore and the gills are located within a polygon (Plates 15 - 18). The rhinophores are long, translucent white at the base and the lamellate clavus is black with a distinct squared tip that is angled. In three photographs of two living individuals, there are 17 lamellae in each of the four rhinophores that can be counted. The gill pocket is large when the gills are extended, with an upstanding pink rim; its margin appears irregular. The six tripinnate gills are translucent white and the edges appear denser white (Plates 16, 17). The pink areas are granular and covered in white tubercles that are also granular. An enlarged detail from one photograph shows that the granules vary in both size and density (Fig. 9 A, from Plate 18). The five preserved specimens (in alcohol or in formaldehyde) are all pale pink with approximately paired, rounded, polygonal, black markings (Fig. 9 C). The black rhinophores are retracted but just visible in most of the material. The white gills were only extended in two preserved specimens, the holotype SMF 360586 and SMF 360587, and the large gill cavity with its thin rim is clearly visible (Fig. 9 B). All preserved specimens are curled ventrally to a greater or lesser extent except the holotype SMF 360586. The black lines remain on the dorsum and are visible through the hyponotum in the holotype SMF 360586 (Fig. 9 D). The foot is narrower than the dorsum, more than 1 / 2 to 2 / 3 the width of the dorsum in the less curled specimens (SMF 360586, SMF 360589). The penis is extruded in specimen A of SMF 360589 (Fig. 9 E). The foot is rounded anteriorly and tapered posteriorly. The anterior margin is bilabiate and both edges appear to be clearly notched in specimen B of SMF 360589 (Fig. 9 F) but this is an artefact of preservation. The oral tentacles are indistinct in all preserved specimens, certainly not as obvious as those of P. liturata or, in fact, most dorids. None of the photographs are helpful in showing them, although the bilabiate margins are just visible in Fig. 9 E. The jaws are formed of three plates (Fig. 10 A). The rodlets are slightly curved, each with a tapered rounded tip; the more worn rodlets have a rounder tip, and some are broken off (Fig. 10 B). The radula is asymmetrical and there are more teeth per row on the left side than the right side. The general shape of the radula is distinctive for the two Phyllidiella mimics, P. liturata and P. hypocrita: long and narrow, rounded at the old end, and with two long tails of sharp teeth at the new end (Fig. 11). The radular formula of Paradoris hypocrita sp. nov. (n = 2) is 53 - 55 x 14 - 16 (left). 0.8 - 11 (right). There is no rachidian, but a narrow space is present down the middle of the radula in its place (Fig. 12 B, C). The hooks of the lateral teeth are grooved, which is very difficult to see (Fig. 12 A, arrowed).	en	Yonow, Nathalie (2020): Red Sea Opisthobranchia 6: Phyllidiidae and their paradorid mimic: new species and new records (Heterobranchia, Nudibranchia, Doridina).

41FDA3B1CD165A9E99E551C773AA8A4C.taxon	description	Description. The single large (32 mm) preserved specimen is mostly black, which forms deep scallops around the mantle sides with three elongations on the left and four irregular ones on the right, almost reaching the mantle margin, and a small one on the posterior margin (Plate 9). These semi-circular areas formed by the black scalloped pattern are white but contain some black patches and bright yellow tips on both the large and small tubercles. The white areas are almost translucent and full of white granules; even the tiniest tubercles have granulated white pigmentation. The large tubercles in each area are white, topped with yellow, and the bases of the pigmented tubercles are more opaque white as well as more granular than the others, which makes them appear ocellated (Fig. 7 B). These white semi-circles are pustulate, as are the yellow parts of the largest tubercles in these areas and elsewhere on the dorsum. There is no coloured edge remaining on the margin in this specimen, but all photographs of living animals show orange spots and / or lines on the mantle margin (Plates 9 - 14) and three display almost complete yellow margins (Plates 12 - 14). The central black area in life bears a few barely discernible pustules, visible only at great magnification. The four large central tubercles are pustulose and irregular. There is one large tubercle just behind the rhinophores followed by two more. These three tubercles are the largest and rugose, with the basal pustules faintly tipped in yellow pigment which deepens towards tips. The white anal papilla is located just behind the third dorsal tubercle and located in a white area; the anal opening is surrounded by tiny black spots. There is one smaller white and yellow pustulose tubercle behind the anal papilla (far right on Plates 9, 11, 13). The deep yellow rhinophores are almost parallel sided with a short tip (Plates 9, 11, 14). They are each set in a tapering white patch with a yellow rhino-tubercle just behind and slightly displaced laterally. The rhinophores have 16 - 20 lamellae (counted from photographs). The preserved specimen is black and white (Fig. 7 A). Both the black and white areas are pimpled with small pustules, which are more obvious on the white areas. The tubercles are very unusual for species of Phyllidia and in preservative resemble the tubercles of Dendrodoris tuberculosa (Quoy & Gaimard, 1832). They are composed of ridges and incomplete rings of smaller pustules, some even tipped with yellow pigment, and very clearly visible in a large living animal (Plates 9, 14). The rhinophores are retracted and the anus is a puckered hole placed after the third tubercle and clearly visible. Ventrally, the spicules of the hyponotum are arranged in a distinctly hatched pattern, and the black pigment shows through from the dorsal side, darkest around the margin (Fig. 7 C-E). The gill leaflets are grey. The uniformly grey foot sole is oval with no black midline and notched anteriorly (Fig. 7 D, E) in the preserved specimen but not in the living specimen (Fig. 7 C). The anterior margin is rounded, the ' lips' are prominent, and the retracted oral tentacles are conical structures with an obvious deep groove on each side, similar to those depicted in the photograph of the living holotype (Fig. 7 C, courtesy of M Schroedl). A dorsal incision to remove the very thick notum revealed a digestive system (Fig. 8) similar of that of other species of the genus excluding the Dendrodoris multituberculata Boettger, 1918 complex [e. g., P. varicosa, P. alyta (Yonow, 1996: figs 7 - 9), P. coelestis Bergh, 1905 (Yonow 2011: figs 14, 15), P. koehleri Perrone, 2000 (Yonow 2012: fig 19)] and matches the drawing by Fahrner and Schroedl (2000 b: fig. 2). The pharyngeal bulb is creamy yellow and bears an upside-down U-shaped concavity on the dorso-posterior side; this is where the retractor muscles attachments and the small pharynx originate. The creamy-white blood gland lies in or over this concavity. The bursa copulatrix (left sphere) is a solid yellowish colour.	en	Yonow, Nathalie (2020): Red Sea Opisthobranchia 6: Phyllidiidae and their paradorid mimic: new species and new records (Heterobranchia, Nudibranchia, Doridina).

E8DA8F4A93C15F1A9C85A23EE4C76E34.taxon	description	Description. The photograph of the living specimen depicts an animal which vaguely resembles a smudged Phyllidiella ' Phyllidiella pustulosa ' with yellow pigment on the top of its crests, which are loosely arranged in groups with black lines around them (Plate 1). These tuberculate areas comprise a large white area and the tubercles arise very sharply as crests or cones, both pale yellow. These crests are low, and those around the margin are either low cones or rounded on top. There are six of these elongated crests forming a ridge along the midline, grouped into three polygonal areas with two single ones situated behind the anus. The rhinophores are located on the anterior sides of the first cluster, and issue from raised sheaths which are faintly yellow; the rhinophores are associated with rhino-tubercles. The visible part of the right rhinophore in the photograph is black and densely lamellated, rounded at the tip. The individual marginal tubercles are very small and nipple-like with a large creamy white base. They are present as a single series along the submargin and the margin is smooth and pale. The preserved specimen is curved ventrally but everything is clearly visible (Fig. 1 A). The dorsal crests and cones are still present in the specimen and appear ' dirty' where they were coloured yellow. The anus is located on the posterior edge of the third tubercular cluster. The right rhinophore was removed and bears 17 lamellae, the lowest four of which are white, and a rounded distal tip. Ventrally, there is no black showing through the hyponotum, nor are there any black markings on the gill leaflets or oral tentacles in the preserved specimen. The foot sole has no black line. The oral tentacles, gill leaflets, and gonopore are all flesh-coloured (Fig. 1 B, C). The oral tentacles are trilobed with a median ridge: the right one (specimen viewed ventrally) is upstanding and the left one is folded over (Fig. 1 C, D). The foot is folded longitudinally (Fig. 1 B, C, D). Anatomically, the dissection of the single specimen confirms placement in the genus Phyllidiella (see Fig. 2). The internal organs were covered by a dark visceral envelope and beneath this was a smaller envelope anteriorly covering the pharynx, pharyngeal bulb, oral glands, and nervous system. When this was removed, a large mass of large leaf-like oral glands covered the pharynx and pharyngeal bulb. The first is long and muscular, forming a large loop. Two strong muscles attach the elongated and bent pharyngeal bulb to the body wall. The bursa copulatrix is a solid sphere with a reddish patch on the ventral-most side.	en	Yonow, Nathalie (2020): Red Sea Opisthobranchia 6: Phyllidiidae and their paradorid mimic: new species and new records (Heterobranchia, Nudibranchia, Doridina).

EECE00D4184D507A997F53908658F1EE.taxon	description	Description. These five specimens and the additional photographs all bear a single dorsal black band enclosing both the rhinophores and the anal orifice (Plates 4 - 8, Figs 3 A- 6 A); it is not quite complete in one specimen and bears a transverse mark in three specimens (Plates 4, 5, Figs 3 A, 4 A). Critically, in all five specimens, the anterior section of this black band is squared, a feature unique to this species. All specimens bear a second thin black line submarginally and faint black markings within the central black ring. The individual tubercles in the central black ' square' and the multiple tubercles in the wide marginal pink band are as described previously: the pink areas are tuberculate with some faint or distinct black markings between them. Between the two black rings is a double or triple row of tubercles, which appears to be another diagnostic character of P. zeylanica. The thin mantle margin is pink. The rhinophores are long and straight in all photographs, black with a white stalk and few white lower lamellae. Photographs of three individuals are also similar and clearly identifiable; the one with slightly higher and more defined tubercles is probably larger than the others (Plate 8), virtually identical to the specimen illustrated from the Maldives (Yonow 2012: pl. 73) that measured 38 mm in length. None of the preserved specimens were relaxed before preservation, but they are moderately flat with the margins slightly curled (as reported previously for preserved specimens) and their rhinophores are all retracted. Of the photographic series of living specimens, SK # 13 has a few that are focused on the rhinophores, and there are 12 - 14 lamellae on each clavus with the lower three or four lamellae being white. This lower white portion is visible on all photographs of all animals even if they are not sharp enough to count the individual lamellae. Ventrally, the foot sole has no black line nor are there any other markings on it or on the hyponotum (Figs 3 B, 4 B, 5 B, 6 B). In four specimens the anterior foot margin is notched and the margin and ' lips' are separated with the triangular oral tentacles set at an angle. In one less relaxed specimen, the ' lips' and margin are contracted around the mouth. In three specimens (Figs 3 B, 4 B, 5 B), black pigment is visible on the oral tentacles.	en	Yonow, Nathalie (2020): Red Sea Opisthobranchia 6: Phyllidiidae and their paradorid mimic: new species and new records (Heterobranchia, Nudibranchia, Doridina).
