The genus Othius Steph. (Coleoptera: Staphylinidae). A key of all Canarian spp. is given, viz. O. brachypterus Woll., O. neglectus n.sp., O. microphthalmus Coiff., O. philonthoides Woll., O. intermedius Korge, and O. coiffaiti Lohse. Several of the species are very similar to eachother; the size and structure of the eyes, the microsculpture of the elytron, and the shape of the male genitalia are found to be the best characters for their separation.
