New finds of rare ground beetle species (Coleoptera, Carabidae) in western regions of Ukraine

Some results of about twenty-year investigations upon the Carabidae fauna in the western regions of Ukraine, such as West Polissia, western Volyn-Podillya and Ukrainian Carpathians, are presented. There are 6 Carabidae species found certainly (confirmed) for the first time in Ukraine: Trechus rivularis, Bembidion transsylvanicum, Agonum hypocrita, A. scitulum, Amara pulpani, Cymindis vaporariorum. Another 5 ones are found for the first time in the western regions: Tachys fulvicollis, Pogonus luridipennis, Laemostenus venustus, Platynus longiventris, Badister collaris. The finds of remainder 33 species are interesting in biogeographical or ecological senses as well as it has to complement data concerning distribution and habitats of these mostly rare or local taxa in the investigated area: Leistus baenningeri, Nebria livida, Calosoma sycophanta, Carabus clathratus, C. menetriesi, C. nemoralis, C. intricatus, Dyschirius thoracicus, Miscodera arctica, Duvalius roubali, D. ruthenus, Trechus amplicollis, Bembidion latiplaga, B. bruxellense, B. humerale, B. schueppelii, Agonum antennarium, Olisthopus sturmii, Amara makolskii, A. quenseli, Harpalus solitaris, Ophonus rupicola, O. subsinuatus, Parophonus maculicornis, Callistus lunatus, Chlaenius kindermanni, Oodes gracilis, Licinus cassideus, Masoreus wetterhallii, Lebia marginata, Philorhizus quadrisignatus, Lionychus quadrillum, Brachinus explodens. Of them, there are unexpected finds of taxa in the remoted from its main distribution range locations or in improper habitats, both with second finds of very rare species after the long time interval in the same or adjacent locations where they were known 100-150 years ago, deverse special attention. Also some new finds are conditioned by previously insufficient data because of taxonomical discussions or difficult identification: Laemostenus tichyi, Agonum hypocrita, Amara makolskii, Chlaenius kindermanni. In general, the results show that even in such relatively well-known faunistically area, as western Ukraine, there are new entomological finds becoming regularly, and these finds often fallout from conventional biogeographical or ecological context. This is an evidence for possibilities of further research as well as requirements of complex ecosystem-biogeographical approaches to research insect diversity.
