Only <i>O. nareuda</i> from the rio Madeira basin has a similarly long anal-fin base length (31.3-32.8% SL), but differs from <i>O. pulchra</i> in number of anal-fin rays (24-26 <i>vs</i> 17-24, usually 19-22 in <i>O. pulchra</i>). Furthermore, mature males of <i>O. pulchra</i> differ from <i>O. fugitiva, O. ecuadorensis</i>, <i>O. dierythrura</i>, <i>O. parecis</i>, <i>O. paraguayensis</i>, and <i>O. microcephala</i>, and the two new species from the rio Orinoco, <i>O. splendida</i>, and <i>O. pao</i>, by the presence of hooks on the 1 st to 22 nd anal-fin branched rays of males, practically on all branched anal-fin rays (<i>vs</i> 1 st to 9 th, mostly 6 th- 7 th, anal-fin branched rays of males with hooks); the anal-fin’s distal border slightly concave to almost straight in mature males (<i>vs</i>, distal border concave); the longer pectoral fin passing a vertical through pelvic-fin origin (<i>vs</i> shorter pectoral fin reaching but not trespassing to vertical through pelvic-fin origin, <i>e.g. vs O. fugitiva</i> in Fig. 3), almost absence of elongation of the 2 nd unbranched dorsal-fin ray (<i>vs</i> noticeably elongate 2 nd unbranched dorsal-fin ray). Additionally, the longer upper jaw in males, females and unsexed specimens differ <i>O. pulchra</i> (26.8-32.5% HL) from <i>O. fugitiva</i> (23.4-30.0% HL) (Fig. 4). Among other characters formerly cited, snout length in males distinghishes <i>O. pulchra</i> (18.0-26.0% HL, mean 21.8% HL) from the sympatric <i>O. splendida</i> (24.1-26.9% HL, mean 25.2% HL), and <i>O. pao</i> (26.7-30.6, mean 28.6% HL) (Fig. 5). <b>Description.</b> Morphometric data given in Table 1. Largest male 32.7 mm SL, largest female 36.9 mm SL. Body elongate and compressed. Greatest body depth at dorsal-fin origin. Snout short, more blunt in males. Head profile gently convex to straight from snout to posterior tip of supraoccipital bone. Predorsal profile slightly convex between posterior tip of supraoccipital bone and dorsal-fin origin, then straight from dorsal-fin origin to caudal peduncle. Ventral profile convex from mouth to anal-fin origin. Anal-fin base straight. Caudal peduncle slightly longer than deep. Head relatively small. Posterior margin of opercle sinusoidal with upper portion concave and lower portion convex. Mouth terminal. Maxilla obliquely positioned ending at vertical through anterior border of eye, and practically at horizontal through inferior border of eye. Premaxillary teeth 5, bearing 7- 10 cusps; central cusp longest (Fig. 6). Maxilla with 2-3 (mainly 2) teeth bearing 6-10 cusps, cusp number decreasing to posterior tip of maxilla. Dentary teeth 7-9 bearing 1-7 cusps, gradually decreasing in size; first 5-6
