Introduction
The two species placed in this genus are very similar in appearance and are most readily separated by the pattern and number of accessory mental barbels. See Mees (1977) for a key to species. This genus occurs from the Orinoco delta, through the Guianas, to the Amazon delta.
Characteristics
