Introduction
I am dipterist with particular interest in some families of Acalyptratae. Anthomyzidae (world) and Sphaeroceridae (Palaearctic) are my preferred families (studied by me in many aspects); marginally I also study systematics, relationships, biology and distribution of a few other groups.

In the second part of the monograph of Palaearctic Anthomyzidae, supplements to adult morphology and, particularly, to taxonomy, classification, nomenclature, preimaginal stages and distribution of species occurring in the Palaearctic Region are presented. Two new genera are established on the basis of phylogenetic analyses: Arganthomyza gen.n. (ty...
Examination of inclusions of Anthomyzidae (Diptera) in Baltic (and Bitterfeld) amber (Tertiary: Eocene) resulted in the finding of 10 new species, eight belonging to Protanthomyza Hennig, 1965 (fossil Protanthomyzinae) and two to Lacrimyza gen. nov. (Anthomyzinae). Protanthomyza and Protanthomyzinae are rediagnosed on the basis of nine species, P....
The Palaearctic taxa of Anthomyzidae are monographed.

Simple Summary
The first finding of a schizophoran fly in Oise amber (France) proved to belong to an extinct genus Hemilauxania Hennig, 1965 (Acalyptratae: Lauxaniidae), known previously only from Baltic amber (ca 48–34 Ma). It is described as a new species, H. parvula, and because it originates from the lower Eocene (about 53 Ma) it is apparently...

Associations of insects that live in nests and burrows of small mammals are relatively poorly explored. This work therefore tries to expand the knowledge about Diptera communities (Psychodidae and Sphaeroceridae) of two small mammals, namely Micromys minutus (Pallas, 1771) and Muscardinus avellanarius (Linnaeus, 1758). In nests of Eurasian harvest...

A total of 31 insect species (Coleoptera 3 spp.,
Diptera 27 spp...
The only preserved (damaged, sex unknown) type specimen of Periscelis (Periscelis) winnertzii Egger, 1862 has been revised and designated as a lectotype. Its revision revealed that P. winnertzii has recently been misinterpreted and is in fact identical with P. (P.) fugax Roháček & Andrade, 2017, syn. nov. Therefore, true P. winnertzii is re-diagnos...
The first data about Sphaeroceridae occurring on eight montane and foothill peat bogs of various types in the North Caucasus (Russia) are presented.

A new Periscelididae species, Periscelis (Myodris) haennii sp. nov. , is described from Losone near Locarno, Canton Ticino (Southern Switzerland). It has been found during a biodiversity survey using attractant traps in a Querco-Castagnetum forest. This new species is closely related and very similar to P. (M.) annulata (Fallén, 1813) occurring syn...
The available keys for European Hippoboscidae are outdated and do not cover all species currently known from Europe. Therefore, identification keys to the eleven genera and 31 species of the European hippo-boscids are provided here. Ornithomya comosa (Austen, 1930) (Diptera: Hippoboscidae) is recorded for the first time from the territory of Slovak...

Two species are dependent o...
Species of the family Anthomyzidae (Diptera: Acalyptrata) occurring in Taiwan are reviewed. Eleven species have been recognized, 8 of them new to science.

Despite more than 250 years of taxonomic research, we still have only a vague idea about the true size and composition of the faunas and floras of the planet. Many biodiversity inventories provide limited insight because they focus on a small taxonomic subsample or a tiny geographic area. Here, we report on the size and composition of the Swedish i...

Despite more than 250 years of taxonomic research, we still have only a vague idea about the true size and composition of the faunas and floras of the planet. Many biodiversity inventories provide limited insight because they focus on a small taxonomic subsample or a tiny geographic area. Here, we report on the size and composition of the Swedish i...
1. Terrestrial snail shells can be considered partial resources for insects, and as such, the expansion of numerous snail species to anthropogenic habitats makes them increasingly available.
2. Here, we address for the first time a complete profile of insects that use empty terrestrial snail shells during the winter period in Central Europe.
3. T...
