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).
出現虹膜 diverticulum; 在在後部的上枕骨頂端的升高又增大的齒; 側線列 24-25; 只有在最先的 4-6 個上的側線管在中央的系列中的前面碟; 側面的軀幹顏色可變的,4-6個明顯的黑色斑塊的包括或列或明顯的從 pterotic 在後部突起到尾鰭基底延伸的深色的斑紋 , 或那些二個彩色斑紋的擴散混合; 上頜骨前的齒 14-18;(通常 15-16) 下顎齒 12-16;(通常 14) 尾部的脊椎骨 15-17, 典型地 17; 在前面的背鰭基底的三角形的有顏色標誌偶然模糊或不存在.(參考文獻 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).
發現於了水流有深色的, 些微混濁的水, 流經混合低的森林與牧場的一片風景.(參考文獻 52874) 在開放野外採集的邊緣採集到了, 但是經過沿著它的淺堆被留下的密集的低森林的水流而且提供影像.(參考文獻 52874) 通常出現於區域中且底部為沙地的地方, 河岸植被進入水或具有邊緣的水生植物, 深色的﹐清澈的或些微混濁的水與有限制的相連動物相.(參考文獻 52874) 擬態 Corydoras diphyes 。 (參考文獻 52874) 因為兩者種佔領不同的小環境，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)
