A new genus and species of the subfamily Tachiniscinae (Diptera, Tephritidae) from Australia

Abstract

A parasitic fly Aliasntra anstralica new genus and species is described, and the subfamily Tachiniscinae is recorded from Australia for the first time. The new species superficially resembles pyrgotid flies by lacking frontal setae and wing pattern, and by having numerous proepisternal setae and brownish yellow body. It possesses a unique structure of female terminalia, which is a synapomorphy of the Tachiniscinae, and the incomplete costal vein, long tubular phallus and elongate spermathecae, which are considered synapomorphies of the tribe Tachiniscini, and is placed in that tribe. © The Author, 2012.
