 In the other species, transformed males have stiff, ossified maxillary barbels, an elongated dorsal-fin spine, ventrally-directed pectoral-fin spine hooks, very elongated pelvic-fin unbranched rays, and a rotated anal-fin base.The four different "Entomocorus" species are not easily distinguished by differences in meristics or morphometrics; however, they are can easily be distinguished by pigmentation, especially in caudal fin markings.In "E. benjamini", the distal half of dorsal caudal fin lobe and the edge of the ventral lobe is pigmented.
