Silken-fungus beetles (Cryptophagidae, Coleoptera) of the Ukrainian Carpathians
Abstract
The results of the revision of taxonomy and species richness of silken-fungus beetles of the Ukrainian Carpathians are presented. In the scope of work, all taxonomic and faunistic summaries of the group from 1820 to current studies are included. Three groups of sources are chosen as basis: the author's original research, analysis of collections of natural history museums, and analysis of literature. Considerable attention is paid to taxonomic changes due to which a variety of synonymic names appeared. A short annotation on species richness and on the most important changes in recent taxonomy is given for genera and subgenera, as well as brief information for each species on actual collected specimens. Estimations of species abundance and key biotopes or altitudinal zones, statuses of presence and possible rarity are given. The indices of actual and expected richness of silken-fungus beetles are specified by systematic groups, which showed the highest richness for two genera — Atomaria (50 species belonging to the two subgenera — Atomaria and Agathengis) and Cryptophagus (44 species). On the other hand, 4 genera are monotypic, of which Spavius, Pteryngium, Paramecosoma, and Ootypus are monotypic worldwide, whereas Sternodea is represented only by one species in the Carpathian region (S. baudii). Of the total number of species (116) indicated by different literature sources and actual records for Ukraine, the presence of 78 species is confirmed by the author’s original records and results of analysis of zoological collections. The remaining 38 species are indicated by ambiguous records in the literature (including adjacent countries) and they are not confirmed by descriptions or collection specimens. Eight species representing the genera Antherophagus (1), Atomaria (2), and Cryptophagus (5) are given for the region’s fauna for the first time. It is shown that the largest number of species and genera is common for forsted piedmont areas, and less so for high elevations. An increase in the number of species is expected in case of further research in Bukovina and, in general, in the north-eastern macroslopes of the Carpathians.
