... Machimus atricapillus is treated as Tolmerus atricapillus (Fallén, 1814) by Lehr (1988) and most subsequent authorities, e.g. (Astakhov et al., 2019;Ghahari et al., 2014;Kahanpää et al., 2014;Larsen & Meier, 2004). However, this generic placement has not been accepted by UK authorities with both Stubbs and Drake (2014) and the UK Diptera checklist (Chandler, 2022) retaining the species in Machimus. ...
We present a genome assembly from an individual male Machimus atricapillus (the Kite-tailed Robberfly; Arthropoda; Insecta; Diptera; Asilidae). The genome sequence is 268.6 megabases in span. Most of the assembly is scaffolded into six chromosomal pseudomolecules, including the X and Y sex chromosomes. The mitochondrial genome has also been assembled and is 16.3 kilobases in length. Gene annotation of this assembly on Ensembl identified 10,978 protein coding genes.

Gall midges in region Odsherred (NWZ) of Denmark-five years systematic local faunistic survey A systematic survey was undertaken of the fauna of phytophagous gall midges (Diptera: Cecidomyiidae: Cecidomyiinae) in a restricted area around Fårevejle in NW Zealand. Plant species occurring in the area were scrutinized for galling and non-galling gall midges based on knowledge of associated host plants. The study area is a typical eastern Danish landscape, i.e. coastal plain dominated by arable farming and having scattered forests, except three distinguishing features: it has tracts much hillier than average, semi-natural grassland is unusually prevalent and appreciable areas are semi-urban with summer cottages. One such cottage lot with natural vegetation has made up the geographical center of gravity of the investigation. During 114 days, a total of 114 species of gall midges have been found. Of these, 91 species were hitherto unknow to the faunistic district, including seven new to the country and one presumably undescribed species. The species accumulation curve has only begun to level off, so probably more species occur in the area. Among habitat types investigated, old unimproved grasslands turned out to harbour most species of gall midges and, notably, a greater share of nationally rare species. In contrast , more man-influenced habitats, such as oldfields, had a more species-poor fauna.

The robber fly Choerades igneus new to the Netherlands (Diptera: Asilidae)
A new species of Asilidae of the subfamily Laphrinae is reported to the Dutch fauna: Choerades
igneus (Meigen, 1820) (fig. 1). It is very similar to the black and red Choerades gilvus (fig. 2).
Several authors treat this taxon as a synonym of C. gilvus (Jaennicke 1867, Lehr 1991), which
was followed by Dutch authors (Van der Goot 1985, Van Veen 1984, 1996). Other authors treat
it as a separate and valid species (Larsen & Meier 2004, Weinberg & Bächli 1995). We have
examined the dna barcodes of both species and conclude that they should be treated as separate
and valid species (fig. 3). It can be separated from C. gilvus by the yellow bristles on the face
(fig. 5) and thorax and the dusted first sternite (fig. 7). Choerades igneus is a recent arrival in
the Netherlands, with the first specimens dating from 1993 and 1995. Since then it has spread
rapidly (fig. 8). Why it is expanding so rapidly is unclear as suitable habitat has been present for
at least a century.
... Their distinctive appearance and relatively large size make robber flies one of the few dipteran groups with potential for targeting by nonspecialist collectors, making it possible to obtain adequate sample sizes over large geographic areas. Robber flies thus have potential importance as subjects of conservation research (Larsen and Meier, 2004). ...
Robber flies (Diptera: Asilidae) represent a diverse family of predatory insects of potential importance to conservation biology. Diversity and vertical distribution of forest robber flies were studied at Western Illinois University's Ira and Reatha T. Post Wildlife Sanctuary from May to October 2008. Canopy traps were used to collect robber flies in the lower and upper understory. Leptogaster flavipes Loew was the most abundant robber fly collected, comprising 43.5% of total captures. Overall, robber flies were significantly more abundant in the lower traps, but diversity and species composition/relative abundance were similar in lower and upper traps. Robber flies were most abundant in June, due primarily to the abundance of L. flavipes during that month. These results indicate that L. flavipes is a substantial component of the robber fly fauna at Post Wildlife Sanctuary. Robber flies are present and active in the upper understory, but the upper understory does not harbor a robber fly fauna distinct from the lower understory.

Trois saisons se sont écoulées depuis la parution de la première liste des asiles de la Manche sous la plume d'Alain Livory (L'Argiope 50, 2005). L'attention portée à ces diptères depuis lors s'est concrétisée par la découverte de 8 nouveaux taxons dont 2 ne sont nommés avec certitude qu'au niveau du genre, portant notre faune départementale à 24 espèces.
Although dipteran communities play a fundamental role in the ecosystem, little is known about their diversity, richness and abundance in different environments. In spite of the importance of Natural Protected Areas (NPAs) as reservoirs of biological diversity, information about community parameters of most insects, including Diptera, are practically unknown in these areas. In this study, we described and compared the composition and structure of Dipteran communities (considering Tabanidae, Asilidae and Syrphidae families) within six (NPAs) of Yucatan, Southeast Mexico, comprising four main vegetation types: seasonally flooded forest, tropical deciduous forest, semi-deciduous tropical forest and coastal dune. We used Malaise-traps to collect samples during a period of two days, twice a month, for one year (2006–2007) within each NPAs. A total of 6 910 specimens belonging to 33 genera and 78 species/morphospecies were recorded. Our results show that the four vegetation types host a vast diversity of dipterans. However, species richness, abundance, diversity and similarity were higher in the communities of tropical deciduous forests compared with those from semi-deciduous forests and coastal dune vegetation, probably as a result of microhabitat differences between sites. We highlight the role of tropical deciduous forests as a refuge for Diptera species and the importance of these forests for conservation of dipteran communities.
Currently, only two species of Andrenosoma are listed from Spain: A. albibarbe (Meigen) and A. atrum (Linnaeus). Here we add three additional species to Spanish list. A. bayardi Séguy, A. cyrtoxys Séguy and A. biacuminatum n.sp. The new species is described and identification key to the Andrenosoma species of Spain is given, as well as new information on the biology and distribution of the genus in Spain.

ew problems in the biological sciences are older than the crisis in taxonomy. The dipterist Willi Hennig already bemoaned the status of affairs in the 1930s in a high school essay that he wrote at the age of 18 (Schlee 1978). He diagnosed that the main problem was the lack of perceived and/or actual scientific rigour in the field. Fortunately, he was able to help reversing the trend with regard to higher-level systematics (Meier 2005) by introducing scientific rigor through the redefinition of ‘phylogenetic relationship’ and ‘monophyly’ and by insisting that only apomorphic character states can demonstrate monophyly. His work started the revival of phylogenetics, which is now a very productive and highly regarded field (Craft et al. 2002). The same has not happened to taxonomy (Wheeler 2004). It is generally acknowledged that taxonomy is important and that our declining skill base for identifying and describing new species is a major problem for science and society (Godfray 2002). However, few solutions are in sight given the scale of the problem and the manpower costs for solving it using the traditional tools.
