Abstract
Anoplodium hymanae sp. n., a symbiont of the holothurian Stichopus californicus, is described from specimens collected near San Juan Island, Washington, U.S.A. Worms of this species have a single median ovary. This characteristic distinguishes them from other members of the genus except A. mediate. Anoplodium hymanae differs most significantly from A. mediale in the form of the vitellaria and the connections of the ducts of the female reproductive tract. Many of the specimens studied had ingested large numbers of cells identified as host coelomocytes; the species is therefore considered to be parasitic.
