An enigma no more: an integrated taxonomic revision of Aenigmetopia Malloch reveals novel phylogenetic placement and four new species (Diptera : Sarcophagidae : Miltogramminae).

Aenigmetopia Malloch is the only endemic genus of miltogrammine flesh flies (Diptera : Sarcophagidae) in Australia and, until now it has been known from a single species, A. fergusoni Malloch. This study constitutes the first comprehensive taxonomic revision of Aenigmetopia. Four new species, Aenigmetopia amissa , sp. nov., A. corona , sp. nov., A. kryptos , sp. nov. and A. pagoni , sp. nov., are described through the integration of molecular and morphological data and characters for genus- and species-level diagnoses are given. Aenigmetopia is included in a molecular phylogenetic analysis for the first time and the genus emerges as the sister taxon to Metopia Meigen, in agreement with morphological evidence. Aenigmetopia is the only Australian endemic genus of the flesh fly subfamily Miltogramminae. This genus was previously known from a single species and specimens had been neither collected nor studied since the early 1900s. This study utilises integrative systematics to describe four new species of genus Aenigmetopia and explores its phylogenetic placement among the miltogrammines for the first time, resolving a novel sister-group relationship between this genus and Metopia.
