A key to the world genera and a checklist of the world species for the family Polleniidae, including distributions, are provided. The following taxonomic and nomenclatural changes are proposed: Nitellia
hermoniella Lehrer, 2007 = Pollenia mediterranea Grunin, 1966, syn. nov., Pollenia bentalia Lehrer, 2007 = Pollenia semicinerea Villeneuve, 1911, syn. nov., Dasypoda angustifrons Jacentkovský, 1941 =

Calyptrates are a megadiverse, actively radiating, group of dipterans, which are widely spread and abundant in nearly all terrestrial environments. Despite huge diversity and economic importance, their phylogeny is far from resolved. Recent attempts employing few taxa seem converging in retrieving monophyly for most of the families and subfamilies, but deep relationships among these, especially for those of the oestroid clade (blow flies and relatives), are labile when not changing.

The genus Stylogaster Macquart (Diptera: Conopidae) is sister to the remainder of the Conopidae. While all other Conopidae are endoparasitoids of aculeate Hymenoptera, species of Stylogaster appear to be endoparasitoids of ‘orthopteroids’, as the only confirmed rearing records are from crickets and cockroaches. Many calyptrate flies have been observed with Stylogaster eggs attached, but since no Stylogaster have been reared from any dipterans, it is still unknown if these flies are hosts, results of accidental oviposition or carry the eggs to the actual hosts.

The world Rhinophoridae are catalogued, recognising 33 genera and 177 species. Nomenclatural information is provided for all genus-group and species-group names, including lists of synonyms and namebearing type data. Species distributions are recorded by country. A key to the world genera is presented.
