It differs also from all congeners, except H. filamentosus Zarske, by having elongated anteriormost portions of the dorsal, pelvic, and anal fins in mature males (Ref. 96858).Description: dorsal-fin rays ii,9-10; anal- fin rays iv-vi, 20-24; pectoral-fin rays i,10-12; pelvic-fin rays i,7 (Ref. 96858).
