A new species of Duvalius from world’s deepest cave (Coleoptera: Carabidae)

ANA SOFIA P. S. REBOLEIRA, VICENTE M. ORTUÑO

Abstract


The new hypogean ground beetle, Duvalius abyssimus n. sp., from Krubera-Voronja, world’s deepest cave (Arabika massif, Western Caucasus) is described and illustrated. Diagnostic morphological characters of the imago, male and female genitalia are provided. Its relations with other Duvalius Delarouzée species from the Western Caucasus geographic area are discussed. An updated overview of the biocoenosis of its peculiar habitat is made.


Keywords
