Halieutichthys is a genus of marine ray-finned fishes belonging to the family Ogcocephalidae, the deep-sea batfishes or sea bats.

Haleutichthys was first proposed as a monospecific genus in 1863 by the Cuban zoologist Felipe Poey when he described Halieutichthys reticulatus,[1] the type locality was given as off Cuba.

[4] The family Ogcocephalidae is classified in the monotypic suborder Ogcocephaloidei within the order Lophiiformes, the anglerfishes in the 5th edition of Fishes of the World.

The mouth is very small, as is the illicial cavity on the snout which is covered by puffy, membranous folds.

[8] These are relatively small anglerfishes with the largest being H. aculeatus with a maximum published total length of 10 cm (3.9 in).
