Table 14 in A taxonomic revision of the Neotropical electric fish genus Brachyhypopomus (Ostariophysi: Gymnotiformes: Hypopomidae), with descriptions of 15 new species

Table 14. Morphometrics for Brachyhypopomus gauderio. HT, holotype; SD, standard deviation. Data for holotype (Rio Grande do Sul, Brazil) are from Giora & Malabarba (2009). Range for the type region refers to non-type specimens from the lagoa dos Patos and Uruguay drainages in Brazil and Uruguay (holotype data excluded). Specimens from the Paraguay drainage refer to non-type specimens from the río Paraguay of Paraguay.
