For a stream near Leticia from where the species was found and observed, the Caño Pichuna has pH 6.83, conductivity 18 μS/cm, and temperatrure (at 12:50 p.m.) of 26.5°C. Recorded food items include larvae of aquatic Diptera, Hymenoptera (presumably ants), Homoptera, Ephemeroptera, aquatic Coleoptera, and larvae of terrestrial Diptera (Phoridae). Reported fecundity of 136 oocytes for mature females were collected in November (Ref. 109742). Lima, F.C.T., V. Correa and R.P.

In that group: the second humeral blotch larger and considerably darker than the first humeral blotch (vs. first humeral blotch larger and considerably more conspicuous than the second humeral blotch, which is vertically elongated and narrow), except H. yinyang to which it differs by the presence of a caudal peduncle blotch (vs. caudal peduncle blotch absent).
