Bopyrinae Rafinesque, 1815

DIAGNOSIS: Female: Head usually fused with first pereomere, frontal lamina absent. Pereomeres often distinct, coxal plates and dorsolateral bosses reduced. Brood pouch often partly or widely open. Pleomeres distinct or fused at least on one side, without lateral plates or uropods. Pleopods smooth, biramous or uniramous.

Male: Head often fused with first pereomere, other pereomeres distinct. Pleon usually fused into single piece, pleopods and uropods often reduced.

REMARKS: Bopyrinae contains 27 genera and 122 species ( Boyko, 2014; herein). All are branchial parasites of caridean shrimps.
