| Remarks |
The holotype (MZUSP 31096) was reported to have been collected in an acidic, slow-flowing, blackwater igarape within the flooded rainforest. Habitat information is lacking for most of the other examined specimens; however, several of the paratype lots (USNM 269994, USNM 269995, USNM 27008) were captured in still rain forest backwaters or in shallow rain forest streams with sandy bottoms and barely perceptible water flow; characterized by blackwaters and numerous submerged logs and branches. Specimens collected in the lower Rio Ucayali basin in northeastern Peru and the region of the Rio japura in Amazonas, Brazil, but not examined in this study, were similarly associated with submerged logs (Ref. 56964). |
