Notes

Identification to species level follows Eigenmann and Eigenmann (1890) based on the following characters: two rows of maxillary teeth (posterior row very small and hidden within the skin folds) and one row of dentary teeth; first dorsal and pectoral rays not spinous; adipose fin long; barbels flattened; upper jaw slightly prognathous; and dark spots on flanks and adipose fin.

Five individuals were caught after being attracted to the boat by suspending a dead-fish bait in the water (sampling site NH12). An example of a live specimen is pictured in Fig. 29.
