Parabopyrella perplexa Markham, 1990: 556– 559 View in CoL , fig. 2 [ Hong Kong, China; infesting “unidentified (caridean?) shrimp”]. — Morton, 2003: 43 (list). — Li, 2003: 140 (list).

Ovobopyrus dentatus An, 2006: 89–90 , fig. 42 (unavailable name).

MATERIAL EXAMINED: Infesting Alpheus digitalis De Haan, 1844 , 1 ♀ ( CIEAL 603301), 2 ♂♂ ( CIEAL 603302), South China Sea, Stn. 6033, 115 ° 00′E, 22 ° 30′N, 11 December 1959, coll. Jinzhao Zhu. 1 ♀, 1 ♂ ( CIEAL 920301), Sanya, Hainan Province, 109 ° 30′E, 18 ° 20′N, 23 March 1992.

DESCRIPTION: Female (CIEAL603301): Length 5.93 mm, maximal width 4.19 mm, head length 1.11 mm, head width 1.54 mm, distorted 26 ° (fig. 17A, B).

Head an inverted trapezoid, without frontal lamina, fused with first pereomere on posterior margin; eyes absent (fig. 17A). Antennule of two articles, antenna of four articles, both nonsetose (fig. 17C). Maxilliped triangular with straight palp, fringed with setae on inner margin (fig. 17D, E). Barbula with two pairs of falcate lateral projections on each side and one pair of rounded projections near median (fig. 17F).

Pereomeres distinct; pereon broadest across third pereomere (fig. 17A). Coxal plates and dorsolateral bosses on first three pereomeres on both sides, but larger on longer side. Brood pouch completely open (fig. 17B), oostegite 1 visible in ventral view, second to fourth oostegite small, fifth oostegite longer than others. Oostegite 1 (fig. 17G, H) with two articles nearly equal in length, internal ridge smooth, posterolateral point directed backward, posterior margin setose. Bases of first four pereopods smaller than those of other three pereopods (fig. 17B). Pleon of six pleomeres, first two pleomeres indicated by dorsal sutures and lateral notches, other pleomeres only distinguished by deep lateral notches. Male inserted in median of five pairs of flaplike biramous pleopods (fig. 17B); uropods absent (fig. 17B).

DESCRIPTION: Male (CIEAL603302): Length 1.77 mm, maximal width (across pereomere 3) 0.65 mm, head width 0.47 mm, head length 0.16 mm, pleonal length 0.42 mm (fig. 17I, J). Head elliptical, fusion with first pereomere indicated by lateral notch between head and first pereomere (fig. 17I); eyes absent (fig. 17I). Antennule of three articles, antenna lacking, nonsetose (fig. 17J). Pereomeres subequal in width, without midventral projections (fig. 17J). Dactyli of first three pereopods larger than those of last four pereopods (fig. 17J). Pleon fused and ovate, segments indicated by lateral indentations. Three midventral projections on median of pleon, pleopods and uropods lacking, two clusters of setae on terminal margin of pleon (fig. 17J).

HOSTS AND LOCALITIES: Infesting Alpheus digitalis De Haan, 1844 (Alpheidae) , and unidentified (caridean?) shrimp, Hong Kong and South China Sea.

REMARKS: Markham (1990) described this species from Hong Kong, but with the host and male both unknown, so the present records are the first with identified hosts and with males. The present females conform well to the holotype female, with only some minor differences: the lateral plates and dorsolateral bosses of the present specimens are on the first three pereomeres but on the first four pereomeres of the holotype ; the posterior margin of oostegite 1 of the present specimens is fringed with setae, but that of the holotype is smooth.
