Redescription of T eredicola typica C. B. Wilson (Crustacea: Copepoda)

SINCE 1942 Teredicola typica has been known to be associated with shipworms in the Hawaiian Islands, but neither the genus nor species has been reported in literature from any other locality, or from any other host group. Dr. C. H. Edmondson of the Bernice P. Bishop Museum, who made the original collections of this interesting copepod, has stated in personal correspondence that he has inquired about the occurrence of copepods in shipworms around the world, but has not yet found anyone who has encountered this parasite. Recently, another copepod parasite has been discovered in Teredo petiti from "lagoons of western Africa" by Rancurel (1954). This copepod, for which a new genus Teredophilus has been proposed, does not seem on the basis of the description to bear any close relationship to Teredicola (see Discussion). The original description of Teredicola typica was made by Dr. Charles B. Wilson in a posthumous paper (1942) and was repeated without emendation in 1944. Records of occurrence of the copepod in the Hawaiian Islands, and observations on its habits and early development are given in papers by Edmondson (1942, 1945). Some corrections and additions to the original description have been made by M. S. Wilson and Illg (1955) in a paper outlining the history and interpretations of the family Clausiidae to which Teredicola is referred. The purpose of the present paper is to place on record a revised and amplified description with illustrations of all
