Abstract

The taxonomic revision of the Eustathiidae is presented. External morpholpgy, host-parasite associations, diagnoses of the family and five new subgenera, and illustrations of species are included. Nine named genera and thirteen named species are recognized. Five new genera and five new subgenera are established. Twenty-nine new species are established and described. The new genera are: Chaeteustathia type species Chaeteustathia chapmani, n. sp., Exileustathia, type species Exileustathia strangulata, n. sp., Fusceustathia, type species Fusceustathia virgata, n. sp., Mimeustathia, type species Mimeustathia -nautii, n. sp., and Lamineustathia, type species Lamineustathia (Lamineustathia) modesta, n. sp. The new subgenera are: Eustathia, Elaphocaulus, Cerceustathia, Lamineustathia, and Phoceustathia. The new species and type hosts are: Eustathia (Eustathia) grandidieri, from Chaetura gra.ndidieri (Apodidae); Eustathia (Eustathia) phoenicobii, from Tachornis phoenicobia (Apodidae); Eustathia (Eustathia) corrugata, from Chaetura cinereiventris (Apodidae); Eustathia (Eustathia) barbati, from Apus barbatus (Apodidae); Eustathia (Eustathia) squamata, from Tachornis squamata (Apodidae); Eusta.thia (Ela.phocaulus) collocali, from Collocalia spodiopygia (Apodidae); Eustathia (Cerceusta.thia) cosmeto, from Chaetura leucop;ygialis (Apodidae); Chaeteustathia chapma.ni, from Cha.etura pelagica (Apodidae); Alleustathia longidiscus, from Chaetura novaeguineae (Apodidae); Fusceustathia -virgata, from Chaetura sabini (Apodidae); Fusceustathia bohmii, from Chaetura bohmi (Apodidae); Fusceustathia cassinii, from Chaetura cassini (Apodidae); Chauliacia crescentica, from Aeronautes andecolus (Apodidae); Chauliacia microlamella, from Aeronautes andecolus (Apodidae); Chauliacia willsii, from Apus melba (Apodidae); Neochauliacia globosa, from Cypseloides zonaris (Apodidae); Neochauliacia attenuata, from Cypseloides zonaris (Apodidae); Neochauliacia transversa, from Czyseloides fumigatus (Apodidae); Neochauliacia triangulata, from Cypseloides rutilus (Apodidae); Neochauliacia ornamenta, from Chaetura pelagica (Apodidae); Neochaulia-longulata, from CoiUocalia leucophaea (Apodidae); Exileustathia strangulata, from Apus melba (Apodidae); Lamineustathia (Lamineustathia modesta, from Hemiprocne mystacea (Hemiprocnidae); Lamineustathia (Phoceustathia) natans, from Chaetura novaeguineae (Apodidae); Lamineustathia (Phoceustathia) hirundii, from Chaetura. gigantea (Apodidae); Leptolichus disimilis, from Chaetura. grandidieri (Apodidae); Leptolichus malaccarensis, from Chaetura gigantea (Apodidae); Mimeustathia -nautii, from Aeronautes saxatilis (Apodidae); Mimeustathia angoli, from Chaetura bohmi (Apodidae).
