Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 2; Μαλακές ραχιαίες ακτίνες (συνολικά) : 7; Εδρικές άκανθες: 1; Μαλακές εδρικές ακτίνες: 5. Hisonotus leucophrys differs from its congeners, except Hisonotus montanus, by having comparatively broader light stripes on dorsolateral surface of head, from snout tip to posterior end of compound pterotic (wider than pupil diameter) vs. narrow light stripes on dorsal surface of head extended from snout tip to posterior end of compound pterotic, or no longitudinal stripes in that region. Hisonotus leucophrys differs from Hisonotus montanus by having the snout covered with odontodes, without an odontode-free band vs. anterior portion of snout with an odontode-free band; and by having an infraorbital canal entering the infraorbital series via the sphenotic vs. infraorbital canal entering the infraorbital series via the compound pterotic (Ref. 80996).
Facultative air-breathing in the genus (Ref. 126274); This species inhabits median to fast flowing watercourses of clear water, with stones and sand on the bottom, and are found in aquatic, partially submersed, vegetation islands composed by grass (Ref. 80996).
