The species of the tribe blondeliini of North and Central America and the west Indies (including Trinidad) are grouped into 55 genera. Included is an illustrated key to thje genera, a diagnosis of each genus, a list of all generic synonyms, and a taxonomic catalogue of all species recorded from these regions, including their new World synonyms. Type status, type locality, and depository of primary type material is given for each nominal species. One hundred and seventy-seven new generic-level synonyms, 67 new species-level synonyms, and 321 new combinations are proposed. Didyma fuliginipennis Wulp, belonging to the tribe Eryciini, was assigned to the genus ametadoria (see under lectotype designation of didyma volucris Wulp). Three new species are described: ligeria latigena n. sp. from Yukon; Policheta crassisetosa n. sp., from Oregon; and Steleoneura novemmaculata n. sp. from Yukon, Banks Island, and Vitoria Island. Lectotypes are designated for 39 nomial species.
The present volume presents a detailed account of the taxonomy, biology and distribution of the European species of Siphonini. This group of tachinid Diptera totals 58 species in Europe of which 6 are here described as new to science. In most species, the immatures live as endoparasitolds of lepidopterous larvae, but a few species even attack tipulid larvae. Several species of Siphonini are of great economic interest as agents for the control of lepidopterous and tipulid pests in agriculture and forestry. An analysis and proposal on the systematic position of the Siphonini is given together with a key to larger taxonomic entities of Tachinidae. The generic classification is also critically emphasized. A separate chapter summarizes aspects of the group's natural history: life-cycles, mating behaviour, oviposition strategies, etc. The taxonomic part contains identification keys to genera and species, and for each species a diagnosis, a description and accounts on the nomenclature, biology and distribution is given. A separate catalogue details the provincial distribution of the 47 species occurring in Fennoscandia and Danmark. No less than 275 line drawings and 15 colour illustrations accompany the text.
While volume 1 includes several introductory chapters and treats 42 families of flies in the Lower Diptera, volume 2 covers the remaining 64 families of flies that make up the Higher Diptera (or Cyclorrhapha). These include families of house flies, fruit flies, bot flies, flower flies and many other lesser-known groups. The text is accompanies by over 1660 line drawings and photographs.
Manual providing an up-to-date, well-illustrated, easily interpretable means for identifying the families and genera of two-winged flies of America north of Mexico. It is also designed to be a basic reference to a wide spectrum of biosystematic information on Diptera. Vol. I includes morphology and terminology of the adult and larval stages, and keys to the families of the order based on both adults and larvae. It also contains the treatments of the 24 families of the Nematocera and the 19 families of the orthorrhaphous Brachycera.
