Habitat comments: "a tropical climate with the rainy season during summer... Most of the original riparian vegetation has been replaced by banana plantations, and some segments of the water course are frequently altered by dredging. . In the surveyed segment no riffles were observed, only small, shallow runs (Fig. 1b). The substrate was predominantly composed of fine gravel and mud, and the aquatic vegetation was dominated by Eichhornia crassipes (Mart.), Potamogeton sp., Lemna gibba L., Pistia stratiotes (L.), and Typha latifolia L."
