O. mimulus is most similar to and can be confused with O. arnoldi. O. mimulus is distinguished from O. arnoldi by having an elevated patch of enlarged odontodes on the postero-dorsal parieto-supraoccipital tip (vs. having a patch of enlarged odontodes on the parietosupraoccipital, and the patch is not elevated).|
|Sexing||Females are larger and broader especially when viewed from above.|
|General Remarks||Mimics Corydoras diphyes. However this 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.|
