Abstract

Pseudocrangonyx shikokunis Akatsuka and Komai, 1922, a poorly known subterranean amphipod, is redescribed and illustrated in detail based on the syntypes from Tokushima Prefecture and four additional specimens from Hyogo Prefecture, Japan. Newly found diagnostic features and morphological variation of the species are discussed.
