Echinoplectanum pudicum is a species of diplectanid monogenean parasitic on the gills of the leopard coralgrouper, Plectropomus leopardus. It has been described in 2006.[1] This species was distinguished from all other species of the genus Echinoplectanum by the shape and small size of its male copulatory organ, and the apparent absence of a sclerotised vagina.
The epithet pudicum (Latin for bashful, chaste) refers to the low level of development of the reproductive organs.[1]
The leopard coral grouper Plectropomus leopardus is the type-host of Echinoplectanum pudicum. The type-locality is the coral reef off Nouméa, New Caledonia.[1] In New Caledonia, this fish harbours three species of the genus Echinoplectanum, namely E. pudicum, E. rarum and E. leopardi.[1]
