Comments: The type locality is a small headwater stream with width of 1-1.5 m, depth of 0.3-1.0 m, moderate current and bottom composed of sand-silt and pebbles in some stretches.  Collected near submerged logs, and caught by overturning a log with the hand-net positioned immediately below.  Occurs syntopically with <i>Knodus cf. savannensis</i> (Characidae), two species of <i>Phenacorhamdia</i> (Heptapteridae), and <i>Melanorivulus cf. zygonectes</i> (Rivulidae) (Ref. 114786).
