A new siphonostomatoid copepod associated with the West Indian sea urchin, Diadema antillarum
The adult female and male of Onychocheres alatus new genus, new species (Copepoda Siphonostomatoidea, family Asterocheridae) are described. These and the later copepodites (at least the stages IV and V) live on the spines (and in the interspinal space) of the tropical shallow-water echinoid, Diadema antillarum Philippi. Although the host is widely distributed in the Atlantic, the copepod appears to be restricted to the mid- and western Caribbean Sea and the Gulf of Mexico. It is probably host-specific, since it was not found on other sea urchins in the same biotope.
