? “parasit bopyrid” Wardiatno, 2004: 81–84 (Japan, infesting N. japonica; see Remarks).
Material examined. Japan: Ovigerous female (10.5 mm, right 1/3 of body sacrificed for molecular work), mature male (2.8 mm), ex left branchial chamber of Nihonotrypaea japonica (7 mm CL, lacking gonopores), Stn 4, 32°47'N 130°36'E, Shirakawa River, Kumamoto, coll. A. Tamaki, 5 Apr 2004 (ULLZ 5471); ovigerous female (8.5 mm, left ½ sacrificed for molecular work), mature male (2.7 mm), ex right branchial chamber of Nihonotrypaea cf. petalura (10.6 mm CL, lacking gonopores), Sample #14, Ariakemachi, coll. A. Tamaki (ULLZ 11653).
Distribution. Japan; Hong Kong; Shandong, Fujian, and Hainan Provinces, China.
Hosts. Nihonotrypaea harmondi (Bouvier, 1901, N. japonica (Ortmann, 1891) (type species), N. petalura (Stimpson, 1860), and Paratrypaea bouvieri (Nobili, 1904).
Remarks. This species belongs to Pseudione sensu stricto (as defined by the resolution of the identity of the type species herein). An et al. (2009) included Saito & Kinoshita (2004: 1–7, figs. 3, 4) in their synonymy list for P. longicauda; however, Saito & Kinoshita (2004) correctly identified their material as Ione cornuta Bate, 1864. Both of the females discussed herein were used to generate 18S rDNA data for the phylogenetic analysis of Boyko et al. (2013) but were erroneously reported in the Supplemental File as being from the same lot.
The specimens studied by Wardiatno (2004) were never named or figured; they are likely either this species or I. cornuta, as these are the only species known from Nihonotrypaea japonica.
