A new genus and species of flower flies (Diptera: Syrphidae: Syrphinae: Syrphini) are described from central Africa (Kenya & Uganda), Afrostoma quadripunctatum. A key to the Afrotropical genera of the subfamily Syrphinae is given. A review of the melanostomine [Bacchini] genera and subgenera is provided along with a key to them. Phylogenetic placement of Afrostoma is included based on mitochond...

In the present paper, the genus Spazigasteroides gen. nov. (Diptera, Syrphidae), with Spazigasteroides caeruleus sp. nov. as type species, is described from China. The new genus bears the following characters: Head strongly concave posteriorly and closely appressed to thorax so that the bare postpronota are entirely hidden. Face black in ground colour. Antennae short, with basoflagellomeres sli...

Flower flies (Diptera: Syrphidae) are one of the most species-rich dipteran families and provide important ecosystem services such as pollination, biological control pests, recycling organic matter redistributions essential nutrients. fly adults generally feed on pollen nectar, but their larval feeding habits strikingly diverse. In present study, high-throughput sequencing was used to capture e...
