Abstract

A new species of Acanthocephala is described based on specimens found parasitising the intestine of the gafftopsail pompano Trachinotus rhodopus Gill in the State of Oaxaca, off the Pacific coast of Mexico. Rhadinorhynchus villalobosi sp. n. differs from the other 25 species of the genus known from the Pacific Ocean by a combination of morphological traits, such as the fewer number of rows of hooks along the proboscis, the distribution of spines of the trunk forming two fields, the position of genital pore, subterminal in both sexes, a shorter neck and cement glands, among others. The phylogenetic analyses based on sequences of the nuclear 18S and 28S rRNA genes, as well as the mitochondrial cox1, all agree that R. villalobosi sp. n. is part of the genus, and closely related to Rhadinorhynchus trachinoti Grano-Maldonado, Sereno-Uribe, Hernández-Payán, Pérez-Ponce de León et García-Varela, 2025, a recently described Mexican species, despite the marked morphological differences between the two and being distributed in different areas.

期刊介绍： FOLIA PARASITOLOGICA, issued in online versions, is an international journal that covers the whole field of general, systematic, ecological and experimental parasitology. It publishes original research papers, research notes and review articles. Contributions from all branches of animal parasitology, such as morphology, taxonomy, biology, biochemistry, physiology, immunology, molecular biology and evolution of parasites, and host-parasite relationships, are eligible. Novelty and importance in the international (not local or regional) context are required. New geographical records of parasites, records of new hosts, regional parasite and/or host surveys (if they constitute the principal substance of manuscript), local/regional prevalence surveys of diseases, local/regional studies on epidemiology of well known diseases and of parasite impact on human/animal health, case reports, routine clinical studies and testing of established diagnostic or treatment procedures, will not be considered. One species description will also not be considered unless they include more general information, such as new diagnostic characters, host-parasite associations, phylogenetic implications, etc. Manuscripts found suitable on submission will be reviewed by at least two reviewers.
