Short Description
Original diagnosis of STEHMANN & WEIGMANN, 2016 [24629]: A small species of the genus Sinobatis distinguished by the cranial feature of having very elongated and extremely narrow fontanelle at its anterior two thirds, but mainly by characters of its clasper. Disc broadly inverse heart-shaped with slightly convex anterior margins and broadly rounded outer and inner pectoral corners; width 64% of TL, length 63% of TL. Head (dorsal length 27% of TL, ventral length 34% of TL) and snout (preorbital length 22% of TL, preoral length 23% of TL, prenasal length 21% of TL) moderately long; snout without rostral filament and angled at 75°. Tail cord-like, hardly tapering towards its tip, and slightly shorter than body. No dorsal fins, caudal fin rather well developed, base lengths of its upper and lower lobes 8% of TL and 6% of TL, respectively. Upper side largely plain medium greyish-brown, underside generally lighter than upper surface, beige with darker outer and posterior areas. Clasper glans with narrow shield, long and distinct pent, slender and smooth-edged distal sentinel and spike but no other cartilage-supported components on outer or inner terminal lobes; clasper skeleton lacking dorsal terminal 1 but with elongated dorsal terminals 2 and 3, narrow twisted ventral terminal with long and curved proximal process, and long, slender, pointed accessory terminals 1 and 2 inserting side by side at inner distal edge of ventral marginal. The combination of colouration, several morphometrics and meristics, as well as few external clasper components and terminal skeletal cartilages distinguishes the species from congeners.
