We present a study of the eastern group of species of the genus Geotrechus (Coleoptera, Carabidae, Trechini), combining molecular and morphological approaches. Four new species are described from caves of the Pyrenees of Catalonia, Spain. Two of the new species belong to the Geotrechus ubachi group sensu novo, like all the species previously known. A new group, the Geotrechus delioti group, is proposed for two new species merged until now with Geotrechus seijasi Español. The molecular study is based on a combination of fragments of four mitochondrial and two nuclear genes. We discuss the distribution of the group and provide a potential scenario of diversification, favouring the hypothesis of allopatric speciation for this old and speciose group of Pyrenean microendemic biota. © 2015 Senckenberg Gesellschaft für Naturforschung.

A molecular phylogeny of the species from the Frechus brucki clade (previously F. uhagoni group) based on fragments of four mitochondrial genes and one nuclear gene is given. We describe Frechus {Frechus} bouilloni sp. n. from the western pre-Pyrenees: Sierras de Urbasa-Andia, Navarra, Spain. The species was collected in mesovoid shallow substratum (mss), a subterranean environment. Molecular as well as morphological evidences demonstrate that the new species belongs to the Frechus brucki clade. A narrow endemic species of high altitude in western French Pyrenees merged with F. brucki Fairmaire, 1862a, F. bruckoides sp. n., is described. A lectotype is designated for F. brucki and F. planiusculus Fairmaire, 1862b (junior synonym of F. brucki). The species group is redefined based on molecular and morphological characters, and renamed as the brucki group, as F. brucki was the first described species of the clade. A unique synapomorphy of the male genitalia, a characteristic secondary sclerotization of the sperm duct, which is shared by all the species of the brucki group sensu novo, is described and illustrated. The T. brucki group sensu novo is composed of Trechus beusti (Schaufuss, 1863), T. bouilloni sp. n., T. brucki, T. bruckoides sp. n., T. grenieri Pandellé, 1867, T. uhagoni uhagoni Crotch, 1869, T. uhagoni ruteri Colas, 1935 and T. pieltaini Jeannel, 1920. We discuss the taxonomy of the group and provide illustrations of structures showing the differences between the species, along with distribution data and biogeographical comments.

In this paper a new Iberian species of Leiodes Latreille, 1797 from Cabeza la Vaca (Sierra de Tudía, Badajoz, Extremadura) is described. Leiodes tudiensis n. sp. shares with some species of the genus the low mesoventral keel, elytral surface with grooves, last antennal article clearly narrower than the penultimate and conus-shaped metatarsi. Palearctic species of Leiodes with these characters are Leiodes brandisi (Holdhaus, 1902), L. ganglbaueri (Holdhaus, 1902), L. piliferus (Reitter, 1885), L. rugosa Stephens, 1829, L. skalitzkyi (Ganglbauer, 1899) and L. taurica (Breit, 1917). However, the structure of the aedeagus only shows similarity to L. taurica, although it is clearly different. The morphology of the aedeagus, together with the color pattern and other morphological details make the new species highly characteristic. Source

Geotrechus sarpedon sp. n., a new species of blind Trechini is described from Arbailles Massif, western Pyrenees, France. The generic attribution of the new species was challenging as it shares morphological features of both genera Geotrechus Jeannel, 1919 and Aphaenops subgenus Hydraphaenops Jeannel, 1926, confirming their polyphyly, which has been highlighted by previous molecular studies on the group. Molecular data suggests unambiguously strong affinities between the new species and the clade Aphaenops vasconicus Jeannel, 1913-A. galani Español, 1968 occurring in the same geographic area, and not related with Aphaenops ehlersi (Abeille de Perrin, 1872), type species of the subgenus Hydraphaenops. The species is included in the paraphyletic genus Geotrechus until its affinities with the other species of Geotrechus and A. (Hydraphaenops) are clarified. © 2013 Magnolia Press. Source

Hypogean Molopina of Pyrenees with the description of a new species of Zariquieya Jeannel, 1924 from Spain (Coleoptera, Carabidae, Pterostichini). A second blind species of the genus Zariquieya Jeannel, 1924, Z. boumortensis n. sp., is described from the southern slope of central spanish Pyrenees (Lleida, Spain). Morphological structure of the new species, especially male and female genitalia as well as the external morphology suggests that this carabid beetle should be included in the genus Zariquieya, created for a single species endemic of eastern Spanish Pyrenees. The new species is morphologically distinct from Z. troglodytes Jeannel, 1924 by numerous characters like maxillary palpus glabrous, pronotum more transverse, frontal impressions lighter, and elytra with fl at disk without strong lateral and apical declivity. A key for identifi cation of Pyrenean Molopina is given, and ecology and biogeographical considerations are detailed, including distribution map of Pyrenean hypogean Molopina. © Publications Scientifi ques du Muséum national d'Histoire naturelle, Paris.
