Several small specimens, ranging in length from 30 to 115 millimeters, were 
taken in the Rio Lempa. One small specimen was seined at Suchitoto, and all 
the others were taken at San Marcos, where the species appears to be common in 
the quiet, shallow, or disconnected pools of the river. No large individuals were 
seen. 
This fish inhabits Pacific-slope streams from Lower California to Peru. The 
specimens in the present collection are from the Rio Lempa at Suchitoto and San 
Marcos.
