Revision of the Metadilepididae (Cestoda: Cyclophyllidea) from Caprimulgiformes (Aves)

Abstract

The type series of Metadilepis globacantha from Caprimulgus europaeus in Sweden and M. caprimulgorum from Chordeiles minor in Brazil are redescribed. The occurrence of the latter cestode species in Hydropsalis climacocerca (as mentioned by Fuhrmann, 1908b, 1932) is questioned. Two new species of Metadilepis from Paraguay are described: Metadilepis kornyushini sp. n. from Nyctibius griseus and M. spasskiorum sp. n. from Setopagis parvula. Metadilepis caprimulgina from Caprimulgus europaeus in Central Russia is considered a species inquirenda. The diagnosis of Metadilepis is amended in order to conform it to the characteristics of M. kornyushini and M. spasskiorum. An identification key to the species of Metadilepis is proposed. Proparuterina aruensis from Podargus papuensis, Aru Island (Indonesia), the type species of Proparuterina, is redescribed. The genus Proparuterina is recognised as monotypic. Proparuterina lali from Passer domesticus in India is considered a species incertae sedis. Mariauxilepis gen. n. with type species M. paraguayensis sp. n. from Nyctidromus albicollis (type host) and Setopagis parvula from Paraguay is erected. Urutaulepis gen. n. is proposed as a monotypic genus for Dilepis pifanoi from Nyctibius griseus in Venezuela. The type species is redescribed on the basis of a paratype specimen and transferred from the Dilepididae to the Metadilepididae as Urutaulepis pifanoi comb. n.
