Metacestodes of the family Dilepididae (Cestoda: Cyclophyllidea) parasitising fishes in Mexico

摘要

A survey of metacestodes of dilepidid tapeworms (Cyclophyllidea) occurring in fish from Mexico is presented. They belong to the following species (those first reported from Mexico marked with an asterisk): Cyclustera capito (Rudolphi, 1819); * Cyclustera cf. ralli (Underwood & Dronen, 1986); Dendrouterina pilherodiae Mahon, 1956; * Glossocercus auritus (Rudolphi, 1819); * G. caribaensis (Rysavy & Macko, 1973); * Paradilepis caballeroi Rysavy & Macko, 1973; * Paradilepis cf. urceus (Wedl, 1855); * Paradilepis sp.; Parvitaenia cochlearii Coil, 1955; * Parvitaenia macropeos (Wedl, 1855); * Valipora campylancristrota (Wedl, 1855); * V. mutabilis Linton, 1927; and * V. minuta (Coil, 1950). Metacestodes of Dendrouterina papillifera (Fuhrmann, 1908), previously reported from the gall-bladder of the pimelodid catfish Rhamdia guatemalensis from Mexico by Scholz et al. (1996), belong actually to V. minuta. Data on the morphology of metacestodes, their fish hosts and rate of infection, site and distribution in Mexico are provided.
