Diagnosis: Parapsilorhynchus odishaensis can be distinguished from its congeners by a following combination of characters: poorly developed callous pad behind lower lip, which is not sharply delimited posteriorly; many prominent horny tubercles on the snout; deep head (depth at occiput 57.2– 75.0% HL); stout and deep body (depth at dorsal fin origin 19.6–25.0 % SL); narrow mouth (23.5–28.6% HL); eye visible from ventral side of head; rounded lower lip; 3-4 simple pectoral fin rays and 33–35 lateral line scales.

Parapsilorhynchus odishaensis , a new cyprinid fish (Teleostei: Cyprinidae ) from Odisha , India Figure 3. Map showing type locality of Parasilorhynchus odishaensis sp. nov. Description: Morphometric data are given on Table 1 . Body small, elongated, somewhat cylindrical, ventral surface flattened. Head depressed with a prominent snout. Snout slightly rounded with many horny tubercles of which two are larger, more prominent, located at anterior sides of snout. Mouth small, inferior, crescent-shaped. Upper lip concealed by a prominent rostral fold, fringed and papillated. A groove present around the corners of the mouth, continuous anteriorly round the outer margin of the rostral fold. Lower lip finely papillated, rounded with a poorly developed callous pad behind it. Callous pad not sharply delimited posteriorly ( Figure 2a ). Eyes moderate size, visible from ventral surface, its diameter smaller than inter orbital space. Barbels one rostral pair, shorter than eye diameter. Dorsal fin inserted slightly in advance of pelvic fin with 3 simple and 7 branched rays, shorter than head length, its origin slightly nearer caudal fin base than tip of snout. Pectoral fin with 3 to 4 simple and 9–11 branched rays, equal or slightly longer than head, not reaching pelvic fin origin. Pelvic fin with one simple and 6–7 branched rays, shorter than pectoral, not reaching anal opening. Anal fin base short, with 1–2 simple and 5 branch rays, not reaching base of caudal fin. Caudal fin forked with rounded lobes. Lateral line complete with 33–35 scales. Scales in lateral transverse rows above lateral line 5 and below lateral line from pelvic fin origin 4. Predorsal scales 17–20, scales arranged irregularly. The air-bladder well developed and distinctly divided into two parts. Colour: Body dark grey with white ventral surface. A black horizontal bar or spot may be present on the caudal peduncle. Dorsal fin with a distinct black oblique bar near its free margin. Pectoral, pelvic and anal fins whitish. Caudal fin dusky with a distinct vertical black bar at its base. Etymology: Named after the Odisha state from where the type specimens were collected. Distribution: Presently known from the tributaries of Mahendra Tanaya River in Rayagada district and Rushikulya River in Ganjam district of Odisha , India ( Figure 3 ).
