Etymology: Otocinclus: Greek, ous, oto = ear + Latin, cinclus = latticework; in allusion to the holes of the head in the ears (Ref. 45335); mimulus: Specific name derived from a Latin word, mimulus, diminutive of minus, meaning actor, given with reference to the mimicry in color pattern with Corydoras diphyes..

脊椎骨: 22 - 23. Presence of an iris diverticulum; elevated, enlarged odontodes at posterior supraoccipital tip; lateral series 24-25; lateral line canals only on first 4-6 anterior plates in median series; lateral trunk coloration variable, including either row of 4-6 distinct dark blotches or distinct dark stripe extending from pterotic posterior process to base of caudal fin, or diffuse mixture of those two color patterns; premaxillary teeth 14-18 (commonly 15-16); mandibular teeth 12-16 (commonly 14); caudal vertebrae 15-17, modally 17; triangular pigment mark at anterior dorsal- fin base occasionally faint or absent (Ref. 52874).
出现虹膜 diverticulum; 在在后部的上枕骨顶端的升高又增大的齿; 侧线列 24-25; 只有在最先的 4-6 个上的侧线管在中央的系列中的前面碟; 侧面的躯干颜色可变的, 4-6个明显的黑色斑块的包括或列或明显的从 pterotic 在后部突起到尾鳍基底延伸的深色的斑纹 , 或那些二个彩色斑纹的扩散混合; 上颌骨前的齿 14-18;(通常 15-16) 下颚齿 12-16;(通常 14) 尾部的脊椎骨 15-17, 典型地 17; 在前面的背鳍基底的三角形的有颜色标志偶然模糊或不存在.(参考文獻 52874)
Facultative air-breathing in the genus (Ref. 126274); Found in stream with dark, slightly turbid water, flowing through a landscape of mixed low forest and pasture (Ref. 52874). Collected at the margin of an open field, but the stream flowed through dense low forest left along its bank and providing shadow (Ref. 52874). Usually occurs in areas with sandy bottom, bank vegetation entering water or with marginal aquatic plants, dark, clear or slightly turbid water and limited associated fauna (Ref. 52874). Mimics Corydoras diphyes (Ref. 52874). Mimicry is unusual because the two species occupy different microhabitats and it is hypothesized to operate with a primarily visual predator moving between the microhabitats, tentatively identified as the cichlid Crenicichla lepidota (Ref. 52874).
发现于了水流有深色的, 些微混浊的水, 流经混合低的森林与牧场的一片风景.(参考文献 52874) 在开放野外采集的边缘采集到了, 但是经过沿着它的浅堆被留下的密集的低森林的水流而且提供影像.(参考文献 52874) 通常出现于区域中且底部为沙地的地方, 河岸植被进入水或具有边缘的水生植物, 深色的﹐清澈的或些微混浊的水与有限制的相连动物相.(参考文献 52874) 拟态 Corydoras diphyes 。 (参考文献 52874) 因为两者种占领不同的小环境，而且它被假定操作，所以擬態是罕見的具有一個被暫時地鑑定為麗魚科的 Crenicichla lepidota 的在小環境之間移動的主要視覺的掠食者.(參考文獻 52874)
