Mravenci (Hymenoptera: Formicidae) Dolního Povltaví

Abstract: The ant fauna of the Dolní Povltaví region (Central Bohemia, Czech Republic) was studied intensively between April 2016 and September 2017. We also used our older data gathered from 1974 onwards. Ants were collected from 71 localities spread throughout the region. We identified there at least 54 ant species, i. e. 61% of the 88 species known to occur in Bohemia. The most interesting habitat was the remnants of natural rocky steppes scattered along the Vltava River and the Zákolanský potok River, where we found 24 species. The rarest species recorded was Lasius myops Forel, 1894, so far known from only a few Czech localities. The relatively frequent occurrence of Colobopsis truncata (Spinola, 1808), along the Vltava River from the outskirts of Prague until its confluence with the Labe River, was also surprising. Other species recorded that are only rarely found in Bohemia include Camponotus aethiops (Latreille, 1798), Myrmica curvithorax Bondroit, 1920, M. gallienii Bondroit, 1920, Aphaenogaster subterranea (Latreille, 1798) and Lasius jensi Seifert, 1982. We conclude that the ant fauna of the Dolní Povltaví region is fairly rich, and is comparable to those known from the other warmest regions of Bohemia.
