A revision of the genus Cantabrogeus Salgado, 2000, with description of three new hypogean species endemic to the Cantabrian mountains (Coleoptera, Leiodidae, Cholevinae, Leptodirini)

Main Article Content
The two previously known species of the genus Cantabrogeus (Coleoptera, Leiodidae, Cholevinae, Leptodirini) are redescribed, and three
new species are described: Cantabrogeus antimachus n. sp., C. cultellus n. sp. and C. fresnedai n. sp. One of these (C. antimachus n. sp.) is tripliod (3n = 33) and the first known parthenogenetic species of Leiodidae. The relationships between the different taxa are discussed based on external morphological characters and the structure of male and female genitalia, as well as the distribution of the species in the different areas in the Cantabrian mountains (NW Iberia). Analyses of molecular data (fragments of seven mitochondrial and nuclear genes) confirms the monophyly of Cantabrogeus and its sister–group relationship with Fresnedaella, as well as its inclusion within the paraphyletic series Quaestus. The parthenogenetic species (C. antimachus n. sp.) has a derived position within Cantabrogeus, which, according to previous estimates of the molecular rate, probably diversified during the Pliocene–Pleistocene in the Cantabrian karst areas, of a high tectonic complexity.
