Down arrow Species Information
Size 96mm or 3.8" SL. Find near, nearer or same sized spp.
Identification Pareiorhaphis species are primarily diagnosed from remaining neoplecostomines by having the canal plate firmly articulated to the preopercle, and by a series of sexually-dimorphic features of hypertrophied odontodes of adult males, giving the fish a hispid appearance.

Distinguished from other Hemipsilichthys species by the exposed lateral process of cleithrum above pectoral fin insertion very reduced in size, never passing the origin of the pectoral fin spine; and by the arrangement of the hypertrophied odontodes on the lateral margin of head, which are longer posteriorly and slightly turned backwards.
