Parabopyrella Markham, 1982

DIAGNOSIS: Female: Head fused with first pereomere except at anterolateral corners; maxilliped with setose palp; barbula with one or two pairs of lateral projections on each side; oostegite 1 with unadorned or sparsely digitate internal ridge; dorsolateral bosses usually on first four pereomeres; pleon of six segments indicated by lateral indentations; pleotelson rounded or produced into posterolateral points; five pairs of flaplike biramous pleopods; uropods absent.

Male: Head usually fused with first pereomere ; eyes present or absent; pereopods subequal in size and shape; pleon variously fused; first pleomere as broad as seventh pereomere or much broader; pleopods tuberculate if present; uropods usually absent.

TYPE SPECIES: Bopyrella mortenseni Nierstrasz and Brender à Brandis, 1929, by original designation.

REMARKS: Although Markham (1985a) purported to erect this genus and restricted the definition of Bopyrella , transfering four western Atlantic species and 20 Indo-West Pacific species to Parabopyrella , in fact the genus name is available from Markham (1982) where it was cited as “in press” but with a type species, Bopyrella mortenseni , designated (the same species was “designated” as the type species in Markham, 1985a). Only one other taxon, Bopyrella deformans indica Chopra, 1923 , was listed as included in the genus when it was introduced by Markham (1982). Markham (1985a) erroneously referred to the 1982 usage of the name as a nomen nudum.

Parabopyrella can be distinguished from Bopyrella in that females of Parabopyrella have lateral indentations that indicate the pleomeres on both sides while the pleomeres of females in Bopyrella are completely fused. Previously, this genus included 26 species, all known from hosts in Alpheidae and Hippolytidae . Two new species are described herein.

According to the shape of the distal margin of the pleotelson of the female, species of Parabopyrella can be divided into three groups (after Bourdon, 1980a). “A” group has the pleotelson tip entire, truncate, or convex and produced into a point in the median and includes six species ( P. angulosa , P. choprai , P. crenulata , P. delagoae , P. perplexa , P. symmetros , n. sp.). “B” group has the pleotelson tip entire, but convex and produced into a rounded distal region and includes eight species ( P. angusta , P. essingtoni , P. mortenseni , P. nierstraszi , P. richardsonae , P. saronae , P. setoensis , P. tanyensis ). “C” group has the pleotelson incised medially, with divergent posterolateral lobes. Within the “C” group, there are four types: “C1” group with the medial incision shallow and the distal ends of the lobes quadrate, and includes five species ( P. australiensis , P. barnardi , P. cuspidata , n. sp., P. elongata , P. pacifica ), “C2” group with the medial incision shallow, but distal ends of the lobes rounded, and includes three species ( P. distincta , P. intermedia , P. thomasi ), “C3” group with the medial incision deep and the distal ends of lobes pointed and long, and includes two species ( P. lata , P. megatelson ), “C4” group with the medial incision shallow but produced into two small points, and includes four species ( P. bonnieri , P. hodgarti , P. incisa , P. indica ).
