Abstract
As presently defined, the tapeworm genus Andrya Railliet, 1895 (Cyclophyllidea: Anoplocephalidae sensu stricto) includes the type species A. rhopalocephala (Riehm, 1881) in hares of the genus Lepus Linnaeus (Leporidae) in western Eurasia and four species in cricetid (Neotominae, Sigmodontinae) and octodontid rodents in North and South America. The host range of Andrya is puzzling, because it is the only genus of anoplocephalid (s. s.) cestodes parasitising both rodents and lagomorphs. The present morphological analysis shows that the American species of Andrya share multiple consistent features, in which they differ from those of A. rhopalocephala and the morphologically related Neandrya cuniculi (Blanchard, 1891). The main differences concern the position of the uterus with respect to the longitudinal osmoregulatory canals and testes. Consequently, a new genus Andryoides gen. n. is proposed for the American species, resulting in the following combinations: Andryoides neotomae (Voge, 1946) comb. n. (type species), Andryoides octodonensis (Babero et Cattan, 1975) comb. n., Andryoides vesicula (Haverkost et Gardner, 2010) comb. n. and Andryoides boliviensis (Haverkost et Gardner, 2010) comb. n. However, A. boliviensis is regarded here as a junior synonym of A. vesicula (new synonymy). The present study also defines the morphological key features for all the valid genera of cestodes of the family Anoplocephalidae (s. s.), and discusses the phylogenetic affinities and historical biogeography of Andryoides and other endemic American anoplocephalid cestodes.
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.
