Etymology: Cynolebias: Greek, kyon = dog + Greek, odous = teeth + Greek, lebias = a kind of small fish (Ref. 45335); oticus: From the Greek adjective oticus, meaning relative to ear, in reference to the continuous otic and post-otic series of neuromasts, which is diagnostic for this species.

簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 15 - 18; 臀鰭軟條: 18 - 21; 脊椎骨: 35 - 36. Cynolebias oticus can be diagnosed from all species of the C. perforatus group by having the otic and post-otic series of neuromasts often united, in close proximity when not united (vs. separated by interspace) and dorsal profile of the head always concave (vs. not concave at least in larger males above 7 cm SL (Ref. 97357).
Body shape (shape guide): fusiform / normal.
Occurs in temporary pools of the Verde river drainage, near the village of Pindaí. The region has been highly deforested in recent years, resulting to the extinction of some seasonal killifishes (Cynolebias gilbertoi, C. leptocephalus, Hypsolebias fulminantis) previously inhabiting the area. C. oticus can still be easily found in the area even under such condition (Ref. 97357).
