Fannidae), dung flies (F. Scathophagidae) and root maggot flies (F. Anthomyiidae). It is comprised of approximately 7000 described species. The monophyly of the Muscoidea and the precise relationships of muscoids to the closest superfamily the Oestroidea (blow flies, flesh flies etc)e ar both unresolved. Until now mitochondrial (mt) genomes were available for only two of the four muscoid families precluding a thorough test of phylogenetic relationships using this data source. Here we present the first two mt genomes for the families Fanniidae (Euryomma sp.) (family Fanniidae) and Anthomyiidae (Delia platura (Meigen, 1826)). We also conducted phylogenetic analyses containing of these newly sequenced mt genomes plus 15 other species representative of dipteran diversity to address the internal relationship of Muscoidea and its systematic position. Both maximum-likelihood and Bayesian analyses suggested that Muscoidea was not a monophyletic group with the relationship: (Fanniidae + Muscidae) + ((Anthomyiidae + Scathophagidae) + (Calliphoridae + Sarcophagidae)), supported by the majority of analysed datasets. This also infers that Oestroidea was paraphyletic in the majority of analyses. Divergence time estimation suggested that the earliest split within the Calyptratae, separating (Tachinidae + Oestridae) from the remaining families, occurred in the Early Eocene. The main divergence within the paraphyletic muscoidea grade was between Fanniidae + Muscidae and the lineage ((Anthomyiidae + Scathophagidae) + (Calliphoridae + Sarcophagidae)) which occurred in the Late Eocene.

Most muscoid flies are sapropha- that no competing interests exist. gous, coprophagous or necrophagous as larvae, but some species are parasitic, predatory or phytophagous. Besides these ‘positive’ roles in the ecosystem, some species such as houseflies carry various pathogenic microorganisms (e.g. Escherichia coli, Shigella spp., Salmonella spp.) [2]. Although muscoid flies have economic and medical importance, with high ecological signif- icance, their phylogenetic relationships are still controversial. Numerous phylogenetic studies have been carried out with morphological and molecular data to reconstruct relationships either within Muscoidea or more broadly across the Calyptratae [1, 3–5]. McAlpine (1989) recovered Muscoidea as a monophyletic group based on a combination of morphological char- acter states [3], while Michelsen (1991) pointed out that Muscoidea was considered as ‘‘the Calyptratae less the Hippoboscoidea and Oestroidea” [6]. Based on four mitochondrial and four nuclear genes from 127 exemplar species of Muscoidea, Kutty et al. (2008) found that Muscoidea was paraphyletic, with the clade (Anthomyiidae + Scathophagidae) sister to a monophyletic Oestroidea. This set of relationships was subsequently also found by Kutty et al. (2010) and Wiegmann et al. (2011) in molecular analyses utilizing different taxon and gene combinations from thosed used in Kutty et al. (2008). On the other hand, in the most compre- hensive morphological phylogenetic analysis of flies ever conducted, Lambkin et al. (2013) recovered the clade Scathophagidae + (Anthomyiidae + (Muscidae + Oestroidea)) [7]; Fannii- dae was not included in this analysis. The evolutionary age of the Muscoidea has also never been directly assessed by phylogenetic means. Wiegmann et al. (2003) [8] suggested that the Calyptratae (represented by a muscid) diverged from the acalyptrates
