First dorsal spine variable in length, often elongate in adults, extending to caudal peduncle in some individuals. Male genital papilla not fimbriate, flattened and relatively elongate with fringe of tiny papillae along distal edge, its maximum length extending slightly beyond origin of anal fin; female papilla short, bulbous, with several finger-like projections, extending to anal-fin spine.

Etymology
