Discovery of a new blind ground beetle in western French Pyrenees, and its relevance to the phylogeny of Pyrenean hypogean Trechini.

Phylogenetic relationships of Western Mediterranean subterranean Trechini groundbeetles (Coleoptera: Carabidae) ARNAUD FAILLE*, ACHILLE CASALE & IGNACIO RIBERA Phylogeny of Mediterranean hypogean Trechini

A new hypogean Trechus Clairville (Coleoptera, Carabidae, Trechini) discovered in a non-calcareous Superficial Subterranean Habitat of the Iberian System (Central Spain).

A new hypogean species of Trechus Clairville, Trechus arrecheai sp. nov., is described from the Iberian Peninsula. It was captured by subterranean pitfall traps in a non-calcareous Superficial Subterranean Habitat from the Moncayo Massif (Zaragoza, Spain). Data on the accompanying fauna are provided and the biogeographical implications of this discovery are discussed. A synthesis of the data ab...

Altitudinal Barrier to the Spread of an Invasive Species: Could the Pyrenean Chain Slow the Natural Spread of the Pinewood Nematode?

Mountain ranges may delimit the distribution of native species as well as constitute potential barriers to the spread of invasive species. The invasive pinewood nematode, Bursaphelenchus xylophilus, is a severe forest pest inducing pine wilt disease. It is vectored in Europe by a native long-horned beetle, Monochamus galloprovincialis. This study explored the potential of the Pyrenean chain to ...

Status of the Brown Bear in the Pyrenees

The population size of the Pyrenean brown bear (Ursus arctos L.) has declined from about 200 animals to 20 or even less during the past 40 years. Distribution covered the Pyrenean slopes from the Atlantic to the Mediterranean Sea but is now restricted to an area of about 800 km2 in the western French Pyrenees. This area includes a national park, which, however, covers only a small portion of th...

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

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 bio...
