Description
Table 15. Morphometrics for Brachyhypopomus janeiroensis, Brachyhypopomus jureiae, and Brachyhypopomus menezesi. HT, holotype; SD, standard deviation. Data for holotype of Brachyhypopomus janeiroensis (Rio de Janeiro, Brazil) are from Costa & Campos-da-Paz (1992). Data for holotype of Brachyhypopomus jureiae (São Paulo, Brazil) are from Triques & Khamis (2003). Ranges for Brachyhypopomus janeiroensis and Brachyhypopomus jureiae refer to non-type specimens from the type region (holotype data not included except for caudal filament length as % TL and LEA in B. jureiae). Ranges for Brachyhypopomus menezesi refer to the holotype and to paratypes from the type region.
