Zhengang Fan ; 1 ♀ ( CIEHI606601 ), South China Sea , Stn. 6066, 113 ° 30′E , 20 ° 30′N , 88 m , 9 April 1960 , coll. Zhican Tang ; 2 ♀♀ ( CIEHI405402 ), East China Sea , Stn. 4054, 123 ° 30′E , 29 ° 30′N , 75 m , 7 April 1959 , coll. Yulin Liao and Ming‐ shou Li . DESCRIPTION: Holotype female (CIEHI790 502a): Length 4.41 mm , maximal width 2.94 mm , head length 0.76 mm , head width 1.24 mm , slightly distorted (fig. 19A, B). Head an inverted trapezoid, lateral margin distinct, posterior margin fused and embed‐ ded in first pereomere. Head with large frontal lamina, boundary between head and frontal lamina obscure; without eyes (fig. 19A). Antennule and antenna of two and three articles, respectively, terminally without setae (fig. 19C). Maxilliped (fig. 19D) without palp, first article cube shaped, short and with blunt spur. Barbula (fig. 19E) with pair of falcate lateral projections on each side and pair of triangular tubercles medially. Pereon broadest across third and fourth pereomeres (fig. 19A). Dorsolateral bosses only on first pereomeres (fig. 19A). Brood pouch widely open (fig. 19B), with seven pairs of oostegites. Oostegite 1 of left side and right side asymmetrical: oostegite 1 of left side (fig. 19F, G) with broad posterolateral point, of right side (fig. 15H, I) with trianglar posterolateral point. Oostegite 1 with smooth internal ridge; oostegites 2, 3 larger than others, oostegite 7 smallest. Pereopods of similar size and structure (fig. 19J, K). Pleon of five pleomeres, first four narrow with obscure sutures. Fifth pleomeres broad and terminally extended into two small tubercles. Five pairs of uniramous flaplike pleopods, uropods lacking (fig. 19B). DESCRIPTION: Allotype male (CIEHI790 502b): Length 1.50 mm , maximal width (across pereomere 2) 0.45 mm , head width 0.31 mm , head length 0.17 mm , pereon length 0.95 mm (fig. 19L, M). Head elliptical, fused with first pereomere but separated by lateral notch between head and pereon (fig. 19L). Black eyes in lateral corners (fig. 19L). Antennule of two articles, antenna of three articles, terminally nonsetose. Pereomeres distinct, lacking midventral projections (fig. 19M). Pereopods with similar structure, but posteriorly smaller (fig. 19M). Pleon with first three segments distinct, last three segments fused but indicated by lateral indentations and ventral sutures. Pleopods and uropods lacking (fig. 19I). VARIATION: One female from CIEHI790501 is different from the other female specimen in the lot as well as all other material as it has very reduced oostegites. ETYMOLOGY: The specific name tozeumaophila refers to the generic name of the host shrimp. HOST AND LOCALITIES: Infesting Tozeuma lanceolatum Stimpson, 1860 (Hippolytidae) , Beibu Gulf, South China Sea, East China Sea, 23– 88 m . REMARKS: The present specimens represent a new genus and species related to Bopyrina and Schizobopyrina . Tozeuma lanceolatum is first recorded here as a host for parasitic isopods. Other species of bopyrids known to parasitize Tozeuma hosts are Parabopyrella thomasi (Nierstrasz and Brender à Brandis, 1929) (infesting T . carolinense Kingsley, 1878 , in St. Thomas) and Schizobopy ‐ rina lobata ( Bourdon and Bruce, 1983 ) (infesting Tozeuma sp. in Queensland , Australia ).
