Two new species from two genera of the family Ampeliscidae Krøyer, 1842 (Crustacea, Amphipoda) from the Clarion-Clipperton Zone, Pacific Ocean

Ampeliscidae is a species-diverse family that inhabits oceans around the world at depths from the intertidal to the hadal zone of 6500 m. During a series of collection expeditions to the Clarion-Clipperton Zone, a number of specimens of the family Ampeliscidae were sampled from depths ranging from 4097 m to 4275 m. Included in these samples were two species unknown to science, Byblis hortonae sp. nov . and Byblisoides jazdzewskae sp. nov . Molecular and morphological examination provides descriptions of these species and keys to the deep water Byblis species and the world Byblisoides species.
