Revision of Chaetophthalmus Brauer & Bergenstamm and the Australian Species of Linnaemya Robineau-Desvoidy (Diptera: Tachinidae).

Abstract

This paper represents a revision of the tribe Linnaemyini in Australia but also includes the description oftwo new species of Chaetophthalmus Brauer & Bergenstamm from Papua New Guinea, being the first species of this genus to be described from outside Australia. Apalpus Malloch is regarded as a synonym of Chaetophthalmus and a key is provided to separate Chaetophthalmus from Linnaemya Robineau- Desvoidy. Keys are also provided to species of Chaetophthalmus (21 species) and Linnaemya (five species). Three new synonymies are proposed in Chaetophthalmus: C. biseriatus Malloch = C. dorsalis (Malloch); C, nudistylum (Macquart) = C. bicolor (Macquart); and C, pallipes (Curran) = C. bicolor (Macquart). Eleven new species are described in Chaetophthalmus: alienus; collessi; flavocaudus; flavopilosus; formosioides; fullerae; innotatus; longimentum; occlusus; setosus; tonnoiri. Three new species are described in Linnaemya: metocha; sarcophagoides; setulosa; L. vulpinoides (Baranov) is recorded from Australia for the first time. Descriptions of the first-instar larva of some species of both Chaetopthalmus and Linnaemya are provided.
