A new cryptic species of Aphaenops (Coleoptera: Carabidae: Trechinae) from a French Pyrenean cave: Congruence between morphometrical and geographical data confirm species isolation

Abstract

A new species of cave-dwelling beetle from the pyrenean massif, Aphaenops (Cerbaphaenops) jauzionin. sp. (Coleoptera: Carabidae), is described. Geometric morphometric analyses based on five morphological structures and comparisons with two populations of the closely related species Aphaenops (Cerbaphaenops) cerberus Dieck 1869 support the uniqueness of the new species. The specific status of the new taxon is also confirmed by the male genitalia structures. A putative scenario of population isolation is proposed. © 2007 Taylor & Francis Group, LLC.
