Table 2. Anal-fin ray counts for 28 species of Brachyhypopomus. Regions: type regions are preceded by an asterisk. Countries: BO = Bolivia, BR = Brazil, CO = Colombia, CR = Costa Rica, EC = Ecuador, FG = French Guiana, PN = Panama, PR = Paraguay, PE = Peru, VE = Venezuela. States/Departments: Brazil: Am = Amazonas, Ba = Bahia, Mg = Minas Gerais, Mt = Mato Grosso, Ms = Mato Grosso do Sul, Rj = Rio de Janeiro, Rs = Rio Grande do Sul, Sp = São Paulo; Paraguay: CE = Central, PH = Presidente Hayes; Peru: Lo = Loreto. For B. occidentalis: Pacific coast drainages (Colombia) = r. Baudó, r. San Juan; lago Maracaibo drainages = r. El Quebradón, r. Motatán, r. San Juan; eastern Atlantic drainages of Panama = r. Cartí, r. Chucubti, and r. Mandinga in the Cuna Yala region from ca. 077°25’W to 079°06’W; western Atlantic drainages of Panama = r. Cricamola from ca. 81°17’W to 081°49’W; eastern Pacific drainages of Panama = r. Bayano, r. Cristal, r. Mamoni, r. Pacora from ca. 079°03’W to 079°44’W. Numbers of examined specimens (N), with T = types, NT = non-types. Counts are recorded in bin intervals of ten, from 140 to 299. Median value shown in bold. Counts reported in original species description but not in the materials examined during this study are marked “^” to show full known range for each species. Missing count values intermediate between reported values are filled with “0” to better illustrate the species ranges. 1º Type = number of anal-fin rays for name-bearing type (parentheses denote count from original description; data for B. occidentalis refers to largest syntype specimen).? = unavailable, D = damaged. Description = range from original description.
