Nine hundred eighty species belonging to 182 genera of 15 subfamilies of the family Dolichopodidae were investigated to study antennal morphology. Length measurements of scape, pedicel, postpedicel and arista and height measurements of postpedicel bases were performed, and 4 ratios were selected. Use of morphometric characteristics of Dolichopodidae antennae allows meaningful distinctions betwe...

The genus Liancalus Loew is revised for the Nearctic Region. Seven species are documented from this region including two new species: Liancalusgenualis Loew, Liancalushydrophilus Aldrich, Liancaluslimbatus Van Duzee, Liancaluspterodactyl sp. n., Liancalusquerulus Osten Sacken, Liancalussimilis Aldrich, and Liancalussonorus sp. n. Lectotypes are designated for the following species: Liancalusgen...

Eighteen species of long-legged flies (Dolichopodidae) are reported as new to Finland. A further species, Microphorellapraecox (Loew), is confirmed as a Finnish species. The status of Hydrophoruscallosoma Frey, 1915 is re-evaluated and a lectotype is designated for the species. Hydrophorusalbosignatus Ringdahl, 1919 is found to be a junior synonym of Hydrophoruscallosoma (syn. n.). Characters f...

Chrysotus weii Zhou, nom. n., the new replacement name is proposed for the species Chrysotus infirmus Wei, Zhang & Zhou, 2014 (Diptera: Brachycera: Dolichopodidae: Diaphorinae), which was preoccupied by Chrysotus infirmus Parent, 1933.

An updated checklist of the Atelestidae, Brachystomatidae, Dolichopodidae, Empididae and Hybotidae (Diptera) recorded from Finland is presented. The genera with uncertain placement within superfamily Empidoidea (= the Iteaphila group) are also included in this paper.

Sinosciapus liuaesp. n. is newly described from Taiwan. The genus Sinosciapus is discussed and a key to the three known Oriental species is provided.

Previously only one species of the genus Diostracus was known to occur in Tibet. Here the following two new species are added to the fauna of Tibet: Diostracusacutatus sp. n. and Diostracustibetensis sp. n. Their relationships with similar species are discussed. A key to the species of Diostracus from the Himalayas is presented.

The family Dolichopodidae forms two of the four largest evolutionary radiations in the Hawaiian Islands across all flies: Campsicnemus (183 spp) and the Eurynogaster complex (66 spp). They also include a small radiation of Conchopus (6 spp). A handful of other dolichopodid species are native to the islands in singleton lineages or small radiations. This study provides a phylogenetic perspective...

Abstract This contribution fills the Diptera biodiversity knowledge gap of two National Nature Reserves in east Slovakia. In total, 53 flies species from 24 families were confirmed NNR Dreveník and Sivá Brada. Among them tree new records Dolichopodidae for fauna Slovakia: Campsicnemus magius (Loew, 1845), Chrysotus palustris Verrall, 1876, Ephydridae: Notiphila ( Agrolimna ) uliginosa Haliday, ...

A review of the species of the genus Chrysotimus from Tibet is provided. The following four species are described as new to science: C. motuoensis sp. n., C. tibetensis sp. n., C. xuankuni sp. n., C. zhui sp. n. A key to the eight Tibetan species is presented.
