Cataphryxus zapoteca sp. nov. (Isopoda, Bopyridae) and new hosts and records of bopyrid isopods from the Mexican Eastern Pacific

Abstract

Based on the examination of diverse crustacean taxa collected along the Mexican Pacific and deposited in the Colección Nacional de Crustáceos of the Instituto de Biología, UNAM, six species of bopyrid isopods were detected. New hosts and localities are reported for Munidion pleuroncodis Markham, 1975, Probopyrus pacificensis Román-Contreras, 1993, Probopyrus markhami Román-Contreras, 1996, Progebiophilus bruscai Salazar-Vallejo & Leija-Tristán, 1990 and Schizobopyrina striata (Nierstrasz & Brender à Brandis, 1929). Cataphryxus zapoteca sp. nov., is described as abdominal parasite of the shrimp Lysmata galapagensis Schmitt; this bopyrid is the second species described in the genus Cataphryxus Shiino, 1936 and the first registered on the American continent. Taxonomic characters, distribution and some reproductive data for five of the six species examined are provided in order to update the knowledge of this parasite group in this Eastern Pacific region.
