Bopyridae

Dorsal (left) and ventral (centre) views of female and dorsal view of male (right) of Parabopyrella richardsonae, from Marilyn Schotte.

Belongs within: Epicaridea.

The Bopyridae are a group of isopods parasitic as adults on decapod crustaceans, while larvae (where known) are parasites of calanoid copepods (Markham 1985).

Characters (from Markham 1985): Female distinctly segmented, slightly to greatly asymmetrical, depressed. Head occasionally fused with first pereomere, sometimes enclosed by frontal lamina; antenna rudimentary; maxilliped of two segments, often with anteromedial palp; posteroventral border of head usually with one or two lateral projections on each side. All seven pereomeres usually distinct; pereopods reduced, usually of seven pairs, though up to six occasionally absent from one side; pereopods prehensile, dorsal to lateral, isomorphic; oostegites of five (rarely seven) pairs often produced into lateral plates resembling pleopodal rami; pleopods generally present on all but final pleomere; pleopods rudimentary or modified for respiration, uniramous or biramous, isomorphic; uropods, when present, terminal, uniramous or biramous, often of same form as pleopods or lateral plates. Male much smaller than female, at least twice as long as wide, symmetrical, distinctly segmented. Head rounded anteriorly, occasionally fused with first pereomere; antennae often prominent. Pereon of seven distinct pereomeres; pair of ventral prehensile pereopods on each pereomere, usually isomorphic except first and sometimes second rarely conspicuously larger than others. Pleon of one to six pleomeres; if unsegmented, usually lacking appendages; if multisegmented, often with sessile to flaplike uniramous or biramous pleopods on each pleomere but last; uropods, if present, uniramous or biramous and terminal.
