Bopyrinella Nierstrasz and Brender à Brandis, 1925

DIAGNOSIS: Female Body long and moderately distorted. Head fused with first pereomere at least medially. Maxilliped without palp, or with setose palp. Narrow coxal plates and obscure dorsolateral bosses on long side. Five or seven pairs of oostegites, only oostegite 1 well developed, right and left oostegites not symmetrical, other oostegites reduced. Pleon of six segments laterally distinct but fused dorsally and sometimes ventrally. Five pairs of flaplike uniramous pleopods. Uropods absent.

Male: Body much longer than wide. Head fused with first pereomere on posterior margin. Pereomeres distinct on dorsal and lateral sides, midventral tubercles lacking. Pleon of six segments, fused at least on ventral surface. Pleopods reduced, no uropods.

TYPE SPECIES: Bopyrinella antillensis Nierstrasz and Brender à Brandis, 1925 (= Bopy ‐ rina thorii Richardson, 1904 ), by monotypy.

OTHER SPECIES: Bopyrinella albida Shiino, 1958 , B. nipponica Shiino, 1936 , B. parameces , n. sp., B. stricticauda Monod, 1933 .

REMARKS: Nierstrasz and Brender à Brandis (1925) erected Bopyrinella with the type species B. antillensis parasitizing Thor floridanus Kingsley, 1878 , from Curaçao. Markham (1985a) regarded B. antillensis as a junior synonym of Bopyrina thorii Richardson, 1904 , known from the same host in Florida; he then removed B. thorii from Bopyrina , making the correct name for the type species Bopyrinella thorii . Monod (1933) described “ Bopyrinella (?) stricticauda ” from an unidentified alpheid in the Gulf of Suez, but while Markham (1985a) thought it did not belong to Bopyrinella , he did not specify what characters indicated that it was not in the correct genus nor did he state where it should be placed. Based on the description and illustrations of Monod (1933), the species may be correctly placed in Bopyrinella , but some characters (particularly those of the mouthparts) are not well described. Shiino (1936) described Bopyrinella antilensis var. nipponica infesting Spirontocaris rectirostris (= Heptacarpus rectirostris (Stimpson, 1860)) from Japan and Markham (1985a) raised it to a full species as B. nipponica . Shiino (1958) described B. albida infesting Athanas kominatoensis Kubo, 1942 (= Arete indicus Coutière, 1903 ), from Japan. Therefore, there are currently four species in Bopyrinella , two on hosts in Hippolytidae and two from hosts in Alpheidae . A new species from a new host species and family, Ogyrididae , is described herein.
