Table 10. Morphometrics for Brachyhypopomus brevirostris. LT, lectotype; SD, standard deviation. Ranges for the type region refer to the lectotype (rio Guaporé) and to non-type specimens from the rio Guaporé in Brazil and río Beni and Mamoré in Bolivia. Ranges for the other populations refer to non-type specimens from the vicinity of Tefé, Amazonas, Brazil (Central Amazonas basin), the río Orinoco drainage in Venezuela (Orinoco drainage), and the upper rio Paraguay drainage in Brazil (upper Paraguay drainage).
