Over recent years, intense field work in caves of Portugal has provided new data on the distribution of subterranean Iberian leiodid beetles. Speonemadus algarvensis sp. nov. is described from caves of southern Portugal. The new species is included in the Speonemadus Jeannel, 1922 escaleraigroup (Cholevinae; Anemadini). All species of the S. escalerai-group are revised and S. breuili (Jeannel, 1922) is resurrected as a valid species. A key to identify the species of the S. escalerai-group is provided and the distinctive characters are illustrated. The distribution of all species of the group is mapped with new data together with biogeographic considerations. © 2017, Museum National d’Histoire Naturelle. All rights reserved.


Aphaobius haraldi sp. n. from the mesovoid shallow substratum (MSS) of the Austrian Alps is described, illustrated, and compared with the closest species of the genus. The new species belongs to the A. kraussi species group, formerly includ-ing five species. It can be readily separated from other species of the genus by the large parameres, with an enlarged apical part, a unique feature among species of Aphaobius. The phylogenetic position of the new species is clarified using mito-chondrial and nuclear data of four related species of Aphaobius, plus some representatives of related genera from the same geographic area. The diversification of the group was estimated to be recent, dating from the Pleistocene. New records and molecular data are provided regarding the enigmatic monospecific genus of the Austrian Alps, Lotharia Mandl, 1944, which was found to be sister to the studied species of Aphaobius. © 2016 Magnolia Press.

The tribe Leptodirini of the beetle family Leiodidae is one of the most diverse radiations of cave animals, with a distribution centred north of the Mediterranean basin from the Iberian Peninsula to Iran. Six genera outside this core area, most notably Platycholeus Horn, 1880 in the western United States and others in East Asia, have been assumed to be related to Leptodirini. We studied recently collected specimens of three of these extraterritorial genera, namely Platycholeus, Fusi Perkovsky, 1989 and Sciaphyes Jeannel, 1910, and establish their phylogenetic relationships by analysing a combination of ca. 5 Kb of mitochondrial and nuclear DNA sequences with Bayesian Probability and Maximum Likelihood methods. Our results corroborate the previously proposed hypothesis that Platycholeus is the sister group of the remaining Leptodirini, with an estimated age of vicariant separation compatible with the breaking of the Thulean bridge between the Nearctic and the Western Palaearctic in the Early Eocene. We refute close relationship of either Fusi or Sciaphyes to Leptodirini, with the former genus appearing more closely related to Cholevini, and the latter to Anemadini and warranting a separate tribe, Sciaphyini, in agreement with recent treatments. This phylogenetic position of Sciaphyes is in agreement with a parsimony analysis of 28 morphological characters of a representative sample of Cholevinae subgroups. We describe one of the studied Sciaphyes species as S. shestakovi sp. n. and indicate its remarkable morphological differences from its congeners. We hypothesise that the remaining three extraterritorial monotypic genera of "Leptodirini", namely Proleptodirina Perkovsky, 1998, Sinobathyscia Perreau, 1999 and Coreobathyscia Szymczakowski, 1975 are unlikely to be closely related to the tribe, which probably has its easternmost geographical limits at Zagros and Alborz (= Elburz) mountains in Iran. © Museum für Tierkunde Dresden.

For management strategies in the context of global warming, accurate predictions of species response are mandatory. However, to date most predictions are based on niche (bioclimatic) models that usually overlook biotic interactions, behavioral adjustments or adaptive evolution, and assume that species can disperse freely without constraints. The deep subterranean environment minimises these uncertainties, as it is simple, homogeneous and with constant environmental conditions. It is thus an ideal model system to study the effect of global change in species with poor dispersal capabilities. We assess the potential fate of a lineage of troglobitic beetles under global change predictions using different approaches to estimate their thermal niche: bioclimatic models, rates of thermal niche change estimated from a molecular phylogeny, and data from physiological studies. Using bioclimatic models, at most 60% of the species were predicted to have suitable conditions in 2080. Considering the rates of thermal niche change did not improve this prediction. However, physiological data suggest that subterranean species have a broad thermal tolerance, allowing them to stand temperatures never experienced through their evolutionary history. These results stress the need of experimental approaches to assess the capability of poor dispersal species to cope with temperatures outside those they currently experience.

Background. Cave organisms have been used as models for evolution and biogeography, as their reduced above-ground dispersal produces phylogenetic patterns of area distribution that largely match the geological history of mountain ranges and cave habitats. Most current hypotheses assume that subterranean lineages arose recently from surface dwelling, dispersive close relatives, but for terrestrial organisms there is scant phylogenetic evidence to support this view. We study here with molecular methods the evolutionary history of a highly diverse assemblage of subterranean beetles in the tribe Leptodirini (Coleoptera, Leiodidae, Cholevinae) in the mountain systems of the Western Mediterranean. Results. Ca. 3.5 KB of sequence information from five mitochondrial and two nuclear gene fragments was obtained for 57 species of Leptodirini and eight outgroups. Phylogenetic analysis was robust to changes in alignment and reconstruction method and revealed strongly supported clades, each of them restricted to a major mountain system in the Iberian peninsula. A molecular clock calibration of the tree using the separation of the Sardinian microplate (at 33 MY) established a rate of 2.0% divergence per MY for five mitochondrial genes (4% for cox1 alone) and dated the nodes separating the main subterranean lineages before the Early Oligocene. The colonisation of the Pyrenean chain, by a lineage not closely related to those found elsewhere in the Iberian peninsula, began soon after the subterranean habitat became available in the Early Oligocene, and progressed from the periphery to the centre. Conclusions. Our results suggest that by the Early-Mid Oligocene the main lineages of Western Mediterranean Leptodirini had developed all modifications to the subterranean life and were already present in the main geographical areas in which they are found today. The origin of the currently recognised genera can be dated to the Late Oligocene-Miocene, and their diversification can thus be traced to Miocene ancestors fully adapted to subterranean life, with no evidence of extinct epigean, less modified lineages. The close correspondence of organismal evolution and geological record confirms them as an important study system for historical biogeography and molecular evolution. © 2010 Ribera et al; licensee BioMed Central Ltd.

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.

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.

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.


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.
