Table 8. Morphometrics for Brachyhypopomus bennetti, Brachyhypopomus bullocki, and Brachyhypopomus cunia. HT, holotype; SD, standard deviation. Data for holotype of B. bennetti (near Manaus, Amazonas, Brazil) are from Sullivan et al. (2013). Data for holotype of B. bullocki (Meta, Colombia) are from Sullivan & Hopkins (2009). Ranges for B. bennetti refer to non-type specimens from the vicinity of Tefé, Amazonas, Brazil. Ranges for B. bullocki refer to non-type specimens from the Orinoco drainage of Venezuela and exclude holotype. Ranges for B. cunia refer to holotype, paratype and non-type specimens from the type region.
