soft rays: 6. Characterized by having escal bulb with two short distally bifurcating papillae on anterior midline, each devoid of pigment and lying very close together; absence of bilaterally placed papillae on dorsal surface of escal bulb; compressed posterior appendage less than length of escal bulb in specimens 33 mm and smaller, more than three times length of escal bulb in 89 mm specimen; unpigmented swollen basal part of posterior appendage in specimens 33mm and smaller, lightly pigmented in 89 mm specimen; absence of connecting membrane between anterior and posterior filaments of posterior escal appendage in specimens 19.5 mm and larger (Ref. 86949).
Also mesopelagic (Ref. 10524).
