Sciomyzidae is a family of acalyptrate flies with 546 species in 61 genera that is among the most extensively studied groups of higher Diptera. Most of the known larvae are obligate enemies of Gastropoda. Hundreds of studies published over the past 50 years have resulted in detailed information concerning morphology of adults and immature stages, biology, development, behaviour, phenology and distribution...
Coenosia bohemica sp. n. is described from the Bohemian Forest in the Czech Republic. Its relationships to similar species are discussed and its diagnostic characters are illustrated.
Today’s knowledge of worldwide species diversity of 19 families of aquatic Diptera in Continental Waters is presented. Nevertheless, we have to face for certain in most groups a restricted knowledge about distribution, ecology and systematic, particularly in the tropical environments. At the same time we realize a dramatically decline or even lack of specialists being able, having the time or the...
Two species of Spilogona, S. angustigena sp. n. and S. tatrica sp. n., are described from the Czech Republic and Slovakia, respectively. Both species are characterised by a gynaecomorphic shape of the male head, i.e., by a broad frons and the presence of a pair of orbital setae.
