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

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