Rhynchactis leptonema is a species of marine ray-finned fish belonging to the family Gigantactinidae, the whipnose anglers. This species is known from widely scattered locations in the Atlantic and Pacific Oceans.
Rhynchactis leptonema was first formally described in 1925 by the English ichthyologist Charles Tate Regan with its type locality given as the western central Atlantic at 8°19'N, 44°35'W from a depth of around 1,500 m (4,900 ft).[2] When Regan described this species, he proposed a new monospecific genus Rhynchactis, so this species is the type species of that genus by monotypy.[3] The genus Rhynchactis is one of two genera in the family Gigantactinidae that the 5th edition of Fishes of the World classifies within the suborder Ceratioidei, the deep sea anglerfishes of the order Lophiiformes, the anglerfishes.[4]
Etymology
Rhynchactis leptonema is a member of the genus Rhynchactis, the name of which is a combination of rhynchos, meaning "snout", with actis, which means "ray", an allusion to the illicium originating at the tip of the snout. The specific name, leptonema, means "slender thread", a reference to the long and thin illicium.[5]
