Proceedings of the United States National Museum SMITHSONIAN INSTITUTION • WASHINGTON, D.C. Volume 122 1967 Number 3600 Genus Gloiopotes and a New Species With Notes on Host Specificity And Intraspecific Variation (Copepoda: Caligoida) By Roger F. Cressey Associate Curator, Division of Crustacea Examination of 94 recent collections of the genus Gloiopotes have made possible a reevaliiation of the species and certain conclusions regarding host specificity and intraspecific variation. In 19G4 Hewitt published an account of Gloiopotes huttoni with notes on the other species. In his paper he placed G. watsoni in synonymy with G. huttoni and attributed the difi"erences to variation within the species. I have been able to show that the two are actually distinct and should be considered separate species. In addition a new species from the Gulf of Mexico is described below. I am indebted to the following persons who generously donated material to me for inclusion in this study: Dr. Bruce CoUette, Bureau of Commercial Fisheries; Dr. Robert Gibbs, Smithsonian Institution; Dr. Richard Gooding, University of Singapore; and Dr. Alan Lewis, University of British Columbia. A portion of the field work was supported by the National Science Foundation, U.S. Program in Biology. All drawings were made with the aid of a camera lucida. All material has been desposited in the Museum of Natural History, Smithsonian Institution. 1
