- Helogenes castaneus (Dahl, 1960)
- Helogenes gouldingi Vari & H. Ortega, 1986
- Helogenes marmoratus Günther, 1863
- Helogenes uruyensis Fernández-Yépez, 1967
Distribution
Helogenes species occur through much of the Amazon River basin, the southern portions of the Orinoco River basin, the coastal rivers of the Guianas, and at least the lower portions of the Tocantins River.[5]
Description
In Helogenes, the dorsal fin base is short, the anal fin base is elongate, the dorsal and pectoral fins lack spines, the adipose fin is usually present, but is reduced or absent in one population of one species.[6][5] Helogenes species grow to about 4.3–7.3 centimetres (1.7–2.9 in) SL.[7]
