The specific epithet leopardi is the genitive form of leopardus and relates to the type-host.[1]
The leopard coral grouper Plectropomus leopardus is the type-host of Echinoplectanum leopardi. 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. leopardi, E. pudicum and E. rarum.[1]
