Olophrinus parastriatus is most similar to O . striatus in sharing the head, pronotum, and elytra with microsculpture consisting of transverse waves, and the right paramere of the aedeagus much broader than the left one. The new species may be separated by the much deeper emargination of male sternite VI, and the relatively much shorter parameres of the aedeagus without a preapical denticle on the ventral surface.
