<paragraphid="B5AA253ADBE05DF53C977C45A8FA2C45"pageId="20"pageNumber="65">Disk circular to pentagonal (dd = 3.06 to 16.68 mm). Uniformly covered by small granules (Fig. 11a), which are smaller in central region than in marginal region. These granules occupy a v-shaped area on the ventral interradius (Fig. 11b). In the areas without granules there are large and imbricating scales. Bursal slits enlarged, with well developed genital scales in margins (Fig. 11b). Oral shields large and rectangular, proximal margin slightly rounded (Fig. 11c). Adoral shields small, almost totally covered by oral shield. Four oral papillae on each side of jaw angle (Fig. 11c). Two proximal papillae slightly cylindrical and subequal, two distal papillae longer and broader. Cluster of well developed dental papillae on apex of jaw (Fig. 11c). Dorsal arm plate longer than wide, fan-shaped (Fig. 11d). Ventral arm plate longer than wide, octogonal, with distal margin slightly convex (Fig. 11e). Two tentacle scales, internal one slightly larger than external one. Three or four arm spines alternating on arm segments. Dorsal spine longer and broader (bottle-shaped) (Fig. 11d), median ones of equal size and ventral one smaller and slightly flattened.</paragraph>
