A recent taxonomic revision of the Neotropical catfish genus Rhamdia (Pisces: Siluriformes: Heptapteridae) reduced a number described species to synonymy, especially under broadly circumscribed R. quelen. Evidence is presented here from DNA sequence data, external morphology, and morphometrics that argues for recognition guatemalensis in Central northern South America saijaensis cinerascens Pacific drainages Colombia Ecuador, respectively. The data indicate all trans-Andean samples form...
This study describes Chrysobrycon calamar , a new stevardiine fish from the upper Río Vaupés basin in Colombia.

Iotabrycon praecox (Characidae: Stevardiinae) has been reported as endemic to the Guayas River drainage in Western Ecuador since its description 1973. We collected one specimen of I. Santa Rosa River, drainage, El Oro Province, approximately 144 km south significantly expanding known geographic distribution species. Given severe anthropomorphic pressures impacting fishes Southwestern Ecuador, there is an urgent need evaluate present status region.
We report collections of several specimens Sicydium in 2013 and 2014 from the Jubones Santa Rosa Rivers southwestern Ecuador. These substantially expand known range genus southward. The are tentatively identified as cf. rosenbergii based on their morphology. Small differences morphology among two rivers noted, discrepancies with type description. A museum database search uncovered additional records south previously recognized including one record northwestern Peru.
