Halieutopsis taiwanea was first formally described in 2021 by the Taiwanese ichthyologist Ho "Hans" Hsuan-Ching with its type locality given as off Yilan, northeastern Taiwan 24°16'12"N, 122°11'24"E from a depth of between 2,246 and 2,356 m (7,369 and 7,730 ft).

[1] In 2007 the specimens that were used to describe this species were thought to be of H. ingerorum but in 2021 Ho recognised that these Taiwanese specimens had different proportions to and were caught in deeper water than the Western Indian Ocean H. ingerorum and described this new species.

[3] 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.

[5] Halieutopsis taiwanea is separable from other species in the genus Halieutopsus by having a face that is strongly upturned with a very short, upwardly-directed rostrum over a small mouth and jaw.

[2] Halieutopsis taiwanea is known only from the three specimens collected off northeastern Taiwan at depths between2,246 and 2,356 m (7,369 and 7,730 ft).
