In this study, we use low-coverage shotgun sequencing of genomic DNA, commonly referred to as genome skimming, to investigate the phylogenetic relationships of the fungus gnat genus Allodia Winnertz (Mycetophilidae, Mycetophilinae, Exechiini). Nineteen specimens, representing 16 in-group and three outgroup taxa, were successfully sequenced and molecular markers of both mitochondrial and nuclear origin were retrieved. The phylogenetic analyses of 13 protein-coding mitochondrial genes, two ribosomal mitochondrial genes and the nuclear ribosomal 18S and 28S strongly support the monophyly of its two subgenera Allodia s.s. and Brachycampta. Complete mitochondrial genomes of 15 species were assembled, which enables further comparisons with the mitochondrial genomes of other Diptera. Overall, the methodology used in this study proved successful and promising for other dipteran groups. In addition to the phylogenetic reconstruction, the morphological characters previously used to separate the two subgenera were evaluated and re-examined. Together with the composite structure of the male genitalia, we consider details of the scutal bristles appropriate for separating the two groups. Based on the achieved results, we reinstate Brachycampta stat. rev. as a separate genus.

An extensive collection of fungus gnats from Nepal and Bhutan, deposited at Kyushu University Museum in Japan, has been examined and revealed nine species of Allodia Winnertz, 1864 new to science: Allodia caligata Magnussen, sp. n., A. dibolia Magnussen, sp. n., A. shimai Magnussen, sp. n., A. spathulata Magnussen, sp. n., A. horologia Magnussen, sp. n., A. himalayensis Magnussen, sp. n., A. nepalensis Magnussen, sp. n., A. thudamensis Magnussen, sp. n., and A. scalprata Magnussen, sp. n. All specimens were collected at high altitudes in the central and eastern Himalayas. The species all belong to the subgenus Allodia s. str. and constitute the first records of the genus Allodia in Nepal and Bhutan. Brevicornu nigrofasciatum (Brunetti, 1912) comb. n., originally described from northern India, is transferred from Allodia based on the original description. A key for the identification of the new species is provided.

Only one species of the genus Allodia has been previously recorded from the Afrotropical region, Allodia (Brachycampta) flavorufa Matile, 1978. Six new species are described here, all representing the nominotypical subgenus, Allodia s.s. The new species are described from material collected in different mountainous areas in south and east Africa; A. jaschhofi sp. nov., A. karkloofensis sp. nov., A. drakensbergensis sp. nov., A. nyeriensis sp. nov., A. mazumbaiensis sp. nov. and A. keurbosensis sp. nov. The species are morphologically very similar, and can only be separated based on minor differences in wing venation and characters of the male terminalia. The genetic differences between the species in the DNA barcode region (CO1), however, support delimitation. The origin and distribution of these Afrotropical taxa, in relation to each other and to their Holarctic relatives, is discussed.
