Short description
पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स
पृष्ठीय रीढ़ (सम्पूर्ण) : 0; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 9; ऐनल सौफट रेज़: 7 - 8; जानवरों की रीड़ का जोड़: 40. Distinguished from most of its congeners, except Ituglanis macunaima and Ituglanis parahybae, by having a pectoral fin ray count of I,4. Differs also from all its congeners, excluding Ituglanis parahybae, by the coloration pattern with longitudinal rows of coalescing blotches. Can be differentiated from Ituglanis parahybae by the supraorbital laterosensory canal branch with pores s3 and s6 present.
Found in brown waters with moderate flowing current and sandy or gravel bottom. Feeds on insect larvae, nymphs and organic matter (Ref. 57703).
