Coralliomyzontidae, Fam. n. (Copepoda: Siphonostomatoida), associated with Scleractinian corals in Madagascar

Coralliomyzon tenens, gen. n., sp. n., associated with the coral Turbinaria peltata gen. n., sp. n., associated with the coral (Esper) in Madagascar, is placed in a new siphonostomatoid family, the Coralliomyzontidae, along with Cholomyzon Stock & Humes, 1969. The new family, close to the Asterocheridae, is characterized chiefly by the maxilliped having 2 basal segments and 2 distal segments forming together a clawlike part, the absence of an inner seta on the first and second segments of the exopod of leg 1, leg 4 reduced to a minute process with 1 or 2 setae, and leg 5 reduced to 2 setae.
