description

Description. Morphometric and meristic data of 281 specimens of P. normani given in Tables 3 and 4. Body moderately deep; dorsal profile rising gently from tip of snout to origin of dorsal fin, sloping gently ventrally from origin of dorsal fin to end of caudal peduncle. Body depth approximately 3.1 times in SL; caudal peduncle slender and moderately long, about 1.5 – 1.8 times longer than deep. Dorsal-fin origin above or posterior to vertical through pelvic-fin insertion. Distance between pelvic-fin and pectoral-fin insertions slightly greater than distance between pelvic-fin insertion and anal-fin origin. Pelvic fin shorter than pectoral fin length, about 1.3 times in HL. Head moderately compressed, snout slightly pointed, longer than eye diameter. Prenostril length about 4.8 times in HL. Tip of snout with 2 – 3 irregular transverse rows of tubercles. Mouth subterminal, lower lips always covered with yellowish horny sheath and post-labial groove always interrupted. Rostral and maxillary barbels almost equal in length, both longer than eye diameter. Dorsal-fin rays iv, 8 and last branched ray always split at base; anal-fin rays iii, 5 last branched ray always split to base; pelvic

diagnosis

Diagnosis. Poropuntius normani is distinguished from all other species of Poropuntius except for P. deauratus and P. laoensis by having a bright lemon yellow caudal fin, with bold submarginal dark stripes on the upper and lower lobes. Poropuntius normani is distinguished from P. deauratus by having its last simple dorsal-fin ray robust and strongly serrated along its posterior margin (vs. slender and very weakly serrated). Poropuntius normani can be distinguished from P. laoensis by having 22 to 31 (mode = 26) pored lateral-line scales (vs. 32 to 36 [mode = 33] for P. laoensis).

discussion

Remarks. Usually in P. normani, the size of tubercles on the tips and sides of the snout are larger and more prominent in males (Figs. 5 A and B). Sometimes during the breeding season, (from November to January), which coincides with the wet season in Peninsular Malaysia, the males show extensive breeding tuberculation on the snout, dorsum of the head, posterior half of the body, and the anal fin (Fig. 5 C). This character is also observed in other species of Poropuntius (Roberts 1998). Note: Asterisk (*) mark indicates specimens collected from similar drainage of type locality.
