MATERIAL EXAMINED: Infesting Birulia kishinouyei, 1 ♀ (CIEHI 401001), 1 ♂ (CIEHI 401002), Yellow Sea, Stn, 4010, 123 ° 30′E, 33 ° 30′N, 60 m, 6 December 1959, coll. Jieshan Xu and Mu Chen.
DESCRIPTION: Female (CIEHI401001): Length 8.38 mm, maximal width 7.30 mm, head length 1.92 mm, head width 2.17 mm, pleon length 2.60 mm, distorted 19 °. All body segments distinct (fig. 7A, B). Head oval, frontal lamina extending beyond head, anterior edge shallowly bilobate, posterior edge curved, eyes absent (fig. 7A). Maxilliped (fig. 7C) with short setose palp and obscure spur. Barbula (fig. 7D) with two pairs of long falcate lateral projections on each side, outer one more slender.
Pereon broadest across third pereomere (fig. 11A). Coxal plates rudimentary on both sides. Brood pouch completely open (fig. 11B). Oostegite 1 (fig. 11E, F) with two equally long articles, nearly smooth internal ridge bearing one large and two or three small projections, posterolateral point directed laterally. Pereopods larger posteriorly (fig. 11G, H), with blunt and small dactyli. Pleon of six pleomeres, lateral plates lacking. Four pairs of small tubercular uniramous pleopods, uropods lacking.

Head a flattened ellipse, posterior edge curved (fig. 11I), black eyes in posterolateral corners (fig. 11I). Antennule of two articles, antenna of four articles, terminally setose (fig. 11K). Pereomeres subequal in width, lacking midventral projections (fig. 11J). Pereopods of subequal size and structure (fig. 11L). Pleon completely fused, without pleopods or uropods, obscure segment demarcations visible in ventral view (fig. 11J).

REMARKS: Bopyroides hippolytes has been described many times in detail (see Markham, 1985a, for a more complete synonymy and discussion). The synonymy list provided here includes only select references published after Markham (1985a). All hosts are in Hippolytidae and Pandalidae. Boyko (2004) recorded this species from Chinese waters infesting Lebbeus cf. spinirostris (Kobjakova) off Taiwan. The present specimens conform well to previous descriptions of this species, but the host and locality are new records. Birulia kishinouyei has not previously been reported as hosting any bopyrid.
