Amphoterus Bezzi, 1915 is a genus of rarely collected Afrotropical hover flies (Diptera, Syrphidae). We present the first description female A. braunsi van Doesburg, 1956, redescribe males 1956 and cribratus 1915, describe new species, londti sp. nov. also provide colour photographs two DNA barcodes for key to identify species.

the species, pharhelophilus versicolor (fabricius), was collected during the study of the syrphid flies (dip.: syrphidae) fauna in sangachin and shijan, guilan province. further confirmation was made by menno reemer. the genus and species is newly recorded from iran.

Three species of genus Cheilosia (Diptera, Syrphidae: Eristalinae) from China are described as new to science, Cheilosia bullabucca Barkalov & Ståhls sp. n., C. lamproptera Barkalov & Ståhls sp. n. and C. yunnanensis Barkalov & Ståhls sp. n. We provide species descriptions and keys for their identification. The phylogenetic placements of the taxa was estimated based on their morphological chara...

Xylota danieli Mutin & Ichige spec. nov. is proposed as the new name for Xylota amamiensis Shiraki sensu Mutin & Gilbert (1999), from the Russian Far East and Japan, which is described and figured. New synonymy is proposed for Xylota coquilletti Hervé-Bazin, 1914 (= X. coquilletti amamiensis Shiraki, 1968 syn. nov.; = X. vulgaris Yang & Cheng in Cheng & Yang, 1993 syn. nov.). 

As part of an ongoing research project on the pollination networks in European heathlands, the objective of this study was to assess the insect visitor guild on Calluna vulgaris (L.) Hull (Ericaceae). We focused the study on a region renowned for its largely well-preserved heathlands, the Cévennes National Park, Southern France. In 2013, flower visitors were observed over 3 d per site, in four ...

Copestylum alberlena, sp. nov. (Diptera: Syrphidae) was reared from larvae collected in decaying platyclades of Opuntia Mill. (Cactaceae) in the state of Veracruz (México). The thirdinstar larva, puparium, and adult morphology are described. Preliminary data about its life cycle and breeding behavior are included. This species is close to Copestylum tamaulipanum (Townsend), also breeding in Cac...
