Description
Table 19. Morphometrics for Brachyhypopomus sullivani. HT, holotype; SD, standard deviation; dr., drainage. Ranges for the type region refer to the holotype and to paratype specimens (and also non-types for caudal filament length as % of TL). Ranges for the other populations refer to non-type specimens from the lower río Beni of Bolivia, and the upper río Orinoco of Venezuela, respectively.
