First record of parasitism in soldier flies by tachinids: Lixophaga stratiophaga Gudin, sp. nov. (Diptera: Tachinidae), reared from Ptecticus testaceus (Fabricius) (Diptera: Stratiomyidae) in Amazon rainforest and updated catalogue of dipteran hosts of Tachinidae

Although tachinids parasitise a wide variety of insects, two‐winged flies are not commonly recorded as hosts. Of the host records from Diptera, most are from larvae of Tabanidae and Tipulidae, with a few occasional records in other families. We present here the first record of parasitism in soldier flies by tachinids and the first record of a dipteran host in the Neotropical Region. Lixophaga stratiophaga Gudin, sp. nov. (Diptera: Tachinidae: Blondeliini) is described and illustrated from pupae of Ptecticus testaceus (Fabricius) (Diptera: Stratiomyidae: Sarginae), collected in fallen fruit of Casearia combaymensis Tul. (Salicaceae) in a reserve of Amazon rainforest in Manaus, state of Amazonas, Brazil. We include notes about its host and discuss the most relevant diagnostic characters for New World species of Lixophaga. An updated and annotated catalogue of dipteran hosts of Tachinidae is also provided, with an overview of host use and oviposition strategies of their respective parasitoids.
