Bagous nodulosus
16. B. nodulosus group Diagnosis. Penis body elongate with sides convergent from base to apex, with ventrobasal margin truncate; dorsal process very high and composed of a pair of very elongate sclerotized pieces, in dorsal view sinuate and joined at base with two small V-shaped vertical orificial s...
