Keilbachia apprima resembles K. nepalensis Mohrig and K. acerspina Mohrig by having the short mesial megaseta of the gonostylus not longer than the mesial width of the gonostylus. Keilbachia apprima differs from K. nepalensis by lacking the sensory pit of the maxillary palp and by having the normal legs and antennae, not strongly elongated, and the gonocoxites without an apicomesial lobe. Keilbachia apprima differs from K. acerspina by having two subapical megasetae and the comparatively large basal body of the mesial megaseta of the gonostylus and by having the normal tegmen without apicolateral teeth.
