Short description
पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स
पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 11 - 13; ऐनल सौफट रेज़: 9 - 10; जानवरों की रीड़ का जोड़: 36 - 39. Oval premaxilla smaller than the maxilla. Pelvic fins with associated pelvic girdle. Branched dorsal fin rays 7-8. Ribs 15-17. Caudal peduncle compressed. The region anteroventral to the dorsal fin origin unpigmented. Head and body lack the very thick, rugose layer of fatty tissue. Lacks extensive perforation on the skin's surface by ampullary organs (Ref. 43677).
Collected from a small, clear water stream, at approximately 3,500 m elevation and 0.5 m deep, running over a sandy bottom and with marginal vegetation limited to grasses. Stomach contents include dipteran larvae (Chironomidae and Simuliidae), coleopterans (Elmidae), trichopterans, and plecopterans (Perlidae) (Ref. 43677).
