背的软条 (总数) : 6 - 7; 臀鳍软条: 9 - 10; 脊椎骨: 29 - 30. Similar to Rivulus amanapira, R. atratus, R. ornatus, R. rectocaudatus, R. romeri, R. tecminae and R. uakti and differs from all other species of the genus by having a frontal squamation pattern consisting of one scale with all margins exposed just posterior to snout (vs. scale with all margins exposed near the center of median portion of frontal region) and an oblique infraorbital dark gray bar through chin (vs. never a similar color pattern). Also similar to R. atratus, R. ornatus and R. romeri and distinguished from the remaining congeners by possessing fewer anal-fin rays (8-10, vs. 11-19). Differs from R. atratus, R. ornatus and R. romeri by having a marginal dark reddish brown stripe on the caudal fin in males (vs. dark marginal stripes absent). Differs further from R. atratus and R. ornatus by the absence of dermosphenotic (vs. presence), absence of preopercular canal (vs. conspicuous short canal), and frontal scales arranged transversally (vs. circularly). Distinguished from R. romeri by having short anal fin, its tip reaching vertical through caudal peduncle (vs. long anal fin in males, tip reaching vertical through caudal-fin base), 32 scales on the longitudinal series (vs. 29-30), 16 scale rows around caudal peduncle (vs. 12) and six branchiostegal rays vs. five (Ref. 54752).
类似 Rivulus amanapira, R. atratus, R. ornatus, R. rectocaudatus, R. romeri, R. tecminae 与 R. uakti 而且藉由有一个有别于所有其他种本属包含一个鳞片的前鳞片的排列图案用正好被暴露的所有边缘经过下巴在吻 (vs. 鳞片以所有的边缘暴露出来在前区域的中央部分的中心附近) 与一条斜的眶下深灰色横带后面.(vs. 从不一个相似的彩色斑紋) 也類似 R. atratus ， R. ornatus 與 R. romeri 而且與剩餘同類區分藉由持有較少的臀鰭棘條.(8-10, vs.11-19) 在雄性中的尾鰭上藉由有一個有別於 R. atratus ， R. ornatus 與 R. romeri 邊緣的紅黑色的褐色斑紋。 (vs. 深色的邊緣斑紋不存在) 進一步不同於 R. atratus 與 R. ornatus 藉由缺少皮蝶骨的 (vs. 出現), 缺乏前鰓蓋骨管 (vs. 顯著的短管), 與橫向地被安排的前鱗片.(vs. 圓地) 與 R. romeri 藉著具有短的臀鰭, 它的頂端達到區分了垂直的經過尾柄 (vs. 長的臀鰭，在雄性中，頂端達到垂直的經過尾鰭基底), 32個鱗片在縱向的系列 (vs.29-30) 上, 16 鱗片列尾柄 (vs.12) 與六個鰓條骨的周圍 vs. 五.(參考文獻 54752)
