Short Description
Original Diagnosis of WALOVICH, EBERT & KEMPER, 2017 [25062]: Hydrolagus erithacus is a large species at maturity (765–945 mm BDL) distinguished from all other congeners based on the following combination of characters: head bulky, large followed by stocky body, height similar from about pectoral fin origins to pelvic fin origins remaining consistent in height until the insertion of the pelvic fins, tall dorsal spine greater in height than first dorsal fin. Second dorsal fin up to 81% of total body length, uniform in height, and equal to dorsal caudal fin height. Paired claspers trifurcate, forked for approximately 20% of total length with fleshy, bulbous tips. Prepelvic tenaculae with five to seven medial spines and thick frontal tenaculum, nearly uniform in width. Coloration after preservation uniform black with no distinct markings. Comparison of mitochondrial NADH2 gene sequences with other related species suggests a distinct lineage.
