Eremitione lata (Shiino, 1958) n. comb. = Parapseudione lata Shiino, 1958 Distribution: Japanese and Russian sides of the Sea of Japan (Shiino 1958; Kornienko et al. 2018). Hosts: Pagurus brachiomastus (Thallwitz, 1891), P. middendorfii Brandt, 1851, P. minutus Hess, 1865, P. ochotensis Brandt, 1851 (Shiino 1958; Kornienko et al. 2018) Remarks: Parapseudione lata cannot remain in Parapseudione as that genus is synonymized with Pleurocrypta in the present work (see below). Aside from the female having four pairs of biramous pleopods and one pair of uniramous pleopods, all the characters of the females and males indicate that this species belongs to Eremitione, and we transfer it to that genus herein. Markham (1986) and Boyko & Williams (2004) suggested that P. lata might be a synonym of Pseudione hyndmanni (Spence Bate & Westwood, 1867). However, given the geographic distance between Japan and Europe, as well as several morphological differences (e.g., smooth oostegite 1 internal ridge in E. lata vs. digitate in P. hyndmanni; male without pleopods in E. lata vs. with pleopods in P. hydmanni; see Bourdon 1968), we retain E. lata as a distinct species.
