Copepoda Associated with Crinoid Echinoderms in the Western Pacific

Abstract

Ten species of copepods are reported from crinoids in the Philippines, the Moluccas, and northern Australia. Siphonostomatoida (Asterocheridae) include seven new species of Collocheres: comanthiphilus, titillator, serrulatus, in.fiatiseta, parvus, thysanotus, and marginatus, and two new species of a new genus, Glyptocheres: extrusus and comanthinae. Glyptocheres may be recognized by the conspicuous posterolateral processes on the genital segment of the female and on the first postgenital segment of the male. Poecilostomatoida (Pseudanthessiidae) are represented by Pseudanthessius comanthi Humes, 1972. Crinoids (Comasteridae) serving as hosts are: Comanthus bennetti, Comanthus samoanus, Comanthus parvicirrus, Comanthus briareus, and Comanthus sp.; Comaster gracilis and Comaster multibrachiatus; Comantheria rotula; and Comanthina variabilis and Comanthina schlegeli.
