Bopyrella Bonnier, 1900

DIAGNOSIS: Female: Body outline elliptical, asymmetrical. Head fused completely or at least medially with first pereomere. Maxilliped with setose palp. Coxal plates very reduced; dorsolateral bosses usually on first four pereomeres. Barbula with two pairs of projections on each side. Brood pouch widely open. All pereomeres fused, segments indicated laterally or dorsally. Four or five biramous flaplike pleopods. Uropods absent.

Male: Head and first pereomere usually fused, juncture indicated by lateral indentations. Pleon much wider than pereon, especially first pleomere. Pleopods and uropods lacking.

TYPE SPECIES: Bopyrella thomsoni Bonnier, 1900 , by original designation.

OTHER SPECIES: Bopyrella articulata , n. sp., B. calmani (Richardson, 1905) , B. harmopleon Bowman, 1956 , B. malensis Bourdon, 1980a , B. moluccensis Bourdon, 1983 , B. tanytelson Markham, 1985 .

REMARKS: Bonnier (1900) erected this genus for Bopyrella thomsoni infesting Alpheus strenuus Dana, 1852 , from “îles des Amis” (= Tonga). Besides the type species, Bonnier (1900) questionably included three other species in Bopyrella : Bopyrus palaemonis Risso, 1816 (nomen dubium), Bopyrina nitescens Giard and Bonnier, 1890 (nomen nudum), and Bopyrus alphei Giard and Bonnier, 1890 (nomen nudum; = Bopyrus alphei Richardson, 1900 = Capitetragonia alphei ( Richardson, 1900) , n. comb., herein). Bourdon (1980a) reviewed Bopyrella and divided it into three groups according to the degree of fusion of the female pleon. Markham (1985a) concluded that the degree of fusion of the female pleon was important at the generic level and transferred 30 species in Bopy ‐ rella to other genera (e.g., Probopyria [= Capitetragonia ], Parabopyrella , Probopyrinella , and Synsynella ). He retained only five species in Bopyrella , all parasitizing alpheid hosts: B. thomsoni , B. malensis Bourdon, 1980a , from the Maldives, B. macginitiei Shiino, 1964 , from California, B. harmopleon Bowman, 1956 , from Venezuela, and B. calmani (Richardson, 1905) , from California. Sassaman et al. (1984) regarded B. macginitiei as a synonym of B. calmani . Bourdon (1983) described B. moluccensis as a new species from the Moluccas and Markham (1985b) described B. tanytelson from Thailand. Therefore, the genus Bopyrella currently includes six well-described species ( Boyko, 2014) plus the poorly known B. palaemonis . An eighth species is described herein.
