Morphology, systematics and distribution of species of the subgenus Eucarabus (Insecta: Coleoptera, Carabidae) in Croatia

Abstract

U Hrvatskoj postoje četiri vrste podroda Eucarabus: Carabus (Eucarabus) arvensis, Carabus (Eucarabus) catenulatus, Carabus (Eucarabus) parreyssi i Carabus (Eucarabus) ulrichi. Utvrđena je rasprostranjenost ovih vrsta u Hrvatskoj i prema tome su izrađene karte rasprostranjenosti. Vrste Carabus (Eucarabus) catenulatus i Carabus (Eucarabus) parreyssi su endemi alpsko-dinarskog područja. Mjerenjem morfoloških značajki tijela pokazano je kako se one mjenjaju s promjenom visine unutar vrsta Carabus (Eucarabus) catenulatus i Carabus (Eucarabus) parreyssi. Prema mjerenim značajkama ukazano je na morfološke razlike između ove dvije endemske vrste. Rezultatima mjerenja napravljen je ključ za razlikovanje i određivanje ovih morfološki vrlo sličnih vrsta, čime bi se nadopunili opisi u postojećim europskim ključevima za trčkeThere are four species of the subgenus Eucarabus in Croatia: Carabus (Eucarabus) arvensis, Carabus (Eucarabus) catenulatus, Carabus (Eucarabus) parreyssi and Carabus (Eucarabus) ulrichi. The distribution of these species in Croatia is presented and accordingly made in to the distribution maps. Species Carabus (Eucarabus) catenulatus and Carabus (Eucarabus) parreyssi are endemic to Alpine-Dinaric area. By measuring the characteristics of the body it was shown how they are changing with the change of altitude within species Carabus (Eucarabus) catenulatus and Carabus (Eucarabus) parreyssi. According to the measured characteristics it was pointed out to the morphological differences between these two endemic species. According to the results of the measured body characteristics a key was made to distinguish and determine these morphologically very similar species, which would supplement the descriptions in the existing European keys for Carabidae
