Manter Laboratory, University of Nebraska State Museum, and School of Biological Sciences, University of Nebraska, Lincoln, Nebraska 68588-0514 ABSTRACT: Five species of Monogenea are reported from fishes of the eastern Pacific Ocean along the coast of California, U.S.A., and Baja California, Mexico. Nudaciraxine cabosanlucensis sp. n. (Axinidae: Axinoidinae) from gills of Ablennes sp. (Belonidae) from south of Cabo San Lucas, Baja California Sur, Mexico, differs from N. gracilis in clamp width, outer marginal hook size and shape, testes number and arrangement, and vaginal pore location. Zeuxapta taylori sp. n. (Heteraxinidae: Heteraxininae) from gills of Thunnus albacares (Scom- bridae) from southwest of San Diego, California, U.S.A., differs from Z. kahala in mouth structure, cirrus shape, esophageal diverticula, and host family. Allencotyla pricei (Heteraxinidae: Heteraxininae) is reported from new hosts, Embiotica jacksoni (Embiotocidae) and Phanerodon atripes (Embiotocidae), and the geographic distri- bution is extended southward from the waters off Redondo Beach, California, to La Jolla, California, and northward to Morrow Bay, California. Leuresthicola robersoni sp. n. (Heteraxinidae: Monaxininae) from gills of Atherinops affinis (Atherinidae) from off La Jolla, California, differs from L. olsoni in clamp number, size and structure, testes number, genital atrium spine size, and host genus. Cynoscionicola powersi (Heteraxinidae: Cynoscionicolinae) from gills of Seriphuspolitus (Sciaenidae), Menticirrhus undulatus (Sciaenidae), and Vmbrina roncador (Sciaenidae) from off La Jolla, California, differs from C. srivastavai in haptor shape, anterolateral atrial pouch trirooted spines, and host species.
