Pseudecheneis sulcata ( McClelland, 1842)

Glyptosternon sulcatus McClelland, 1842: 587, Pl. 6 Figs. 1–3 (type locality: Kasyah [Khasi] Hills, Meghalaya, India)

Pseudecheneis sulcatus – Blyth, 1860: 154; Wu et al, 1981: 75– 76 (Motuo and Chayu of Tibet); Wu & Wu, 1992: 534–536, fig. 147 (Motuo of Tibet); Zhang et al, 1995: 131–132 (Chayu of Tibet).

Pseudecheneis sulcata – Ng, 2006a: 47–51 View Cited Treatment , Fig. 1; Thomson & Page, 2006: 61 (Brahmaputra drainage).

Diagnosis. – Pseudecheneis sulcata is distinguished from congeners except P. paviei , P. sulcatoides , and P. sympelvica in lacking a prominent bony spur on the anterodorsal surface of the first dorsal-fin pterygiophore (vs. spur present; Fig. 2 View Fig ). Pseudecheneis sulcata can be distinguished from P. paviei and P. sympelvica in having an elongate body with 36–39 vertebrae (vs. short body with 33–35 vertebrae) and 12–14 (vs. 8–12) transverse laminae on the thoracic adhesive apparatus, and further differs from P. sympelvica in having separate (vs. fused) pelvic fins. It differs from P. sulcatoides in having a longer caudal peduncle (25.0–28.3% SL vs. 22.5– 23.7), a first dorsal-fin element (vs. element absent), and bifid (vs. non-bifid) neural spines on the complex vertebra. Pseudecheneis sulcata can be further distinguished from P. crassicauda in having a more slender caudal peduncle (4.0– 5.2% SL vs. 6.0–6.6) and larger eye (8.8–10.6% HL vs. 7.5– 8.3), from P. eddsi in having a longer pelvic fin (21.2–28.7% SL vs. 18.0–20.9), from P. immaculata in having (vs. lacking) pale colored patches on the body and shorter adipose-fin base (17.8–22.7% SL vs. 27.7), and from P. serracula in having a shorter adipose-fin base (17.8–22.7% SL vs. 26.8–30.4) and the neural spines of the last 2–3 preanal and first 6–7 postanal vertebrae gradually increasing in height (vs. corresponding neural spines strongly elevated). It further differs from P. stenura in having a shorter caudal peduncle (25.0–28.3% SL vs. 30.3–34.5) and pectoral fin (121.6– 156.3% HL vs. 160.4–196.9), and from P. tchangi in having fewer transverse lamellae (12–14 vs. 21) on the thoracic adhesive apparatus. Vertebrae 18+19=37. Diagnosis and data from Ng (2006a).

Distribution. – This species is found in the Brahmaputra drainage ( Fig. 11 View Fig ).
