Catops cavicis n. sp. from the Krubera-Voronya cave (Abkhazia, Caucasus), an interesting species of the C. alpinus group (sensu Perreau, 2000) (Coleptera, Cholevidae)

Abstract: Catops cavicis n. sp. from the Krubera-Voronya cave (Orto Balagán, Arabika Mts, Abkhazia Rep., Caucasus) is described. This new species, belonging to the group of C. alpinus (sensu Perreau, 2000), is closely related to C. cavazzutii Giachino, 1988, of the eastern Pontic Alps, and constitutes its northern vicariant. The author provides ecological and chorological
data on the new species and discusses the zoogeographic hypotheses on the origin of the phenomena of differentiation in the
south-western species of this group.
