Hypopygus ortegai generates a tetraphasic EOD ranging in duration from 1.17 to 2.11 ms (mean 1.73, N = 7), and with a PPF ranging from 1.408 to 1.869 kHz (mean 1.661, N = 7). Mean pulse rate during the day ranges from 44.7 to 56.8 Hz (mean 50.3, mean CV 0.91, N = 8), and during the night from 59.2 to 65.5 Hz (mean 62.1, mean CV 2.87, N = 8) (Ref. 88778). de Santana, C.D. and W.G.R.

Stomach contents (N = 5) included a variety of autochthonous aquatic invertebrates – mostly larvae of Chironomidae, Trichoptera, Coleoptera, and Ephemeroptera, and some remains of small shrimps. Hypopygus ortegai occurs syntopically with H. lepturus. Whereas H. lepturus is found in groups of up to several dozen individuals, H. ortegai is usually only found in groups of no more than three or four individuals. Additionally, whereas H. lepturus is found in streams both under rainforest canopy and in open areas (e.g. cleared farmland), H. ortegai is restricted to streams under dense forest canopy (Ref. 88778). de Santana, C.D. and W.G.R.
