Four new species of Blennidus subgenus Agraphoderus are described from the Andes of Southern Peru: B. (A.) procerus n. sp., B. (A.) abramalagae n. sp., B. (A.) etontii n. sp. and B. (A.) straneoi n. sp. Together with B. (A.) jelskii (Tschitschérine, 1897), they form a very homogeneous group of probably closely related species (the jelskii group), which is distinguished from other members of the subgenus by the distinctive morphology of the aedeagus. A redescription of B. (A.) jelskii is given based on the lectotype and paralectotype designated by Straneo & Vereshagina (1991), supplementing Tschitschérine's brief original description. The distribution pattern of the species presently included in the jelskii species-group is discussed, emphasizing distinctive traits of stenoendemic species inhabiting restricted geographical areas, and discussing their possible origin by allopatric speciation. © 2011 Museu de Ciències Naturals de Barcelona.

Five new species of genus Leptomeson Jeannel, 1924 are described here, four from Croatia and one from Bosnia and Herzegovina: L. radjai n. sp. of from the pit Zvekača, close to Šibenik, L. dalmatinus n. sp. from the pit Maravića jama, on the island of Čiovo, L. bujasi n. sp. from the pit Jama kod Matešića stana, on the island of Brač, L. biokovensis n. sp. from the pit Pretnerova jama, on the Biokovo Mountain and L. raguzi n. sp. from the cave Majića ponor, near Grude. Moreover, some new chorological data are given on L. dombrowskii dombrowskii (Apfelbeck, 1907), found in the cave Baba špilja, on Biokovo Mountain (Dalmatia).

Subterranean ecosystems often harbour unique and specialised biocoenoses of considerable scientific interest and high potential conservation value. In view of the peculiar species assemblage in the abandoned tunnels of a talc mine complex in the north-western Italian Alps (Germanasca Valley, Province of Turin, NW Italy), the aims of the present work were (i) to investigate the subterranean invertebrate fauna, (ii) to assess the impact of tourism activities on the invertebrate fauna, and (iii) to assess the conservation value of the terrestrial invertebrate community and associated habitats. The study was carried out at four sites: one tunnel restored for tourism purposes; two abandoned tunnels; and a wild cave. The results of several statistical analyses, including ANOVA, PCA and CCA, showed that the eutrophic conditions induced by past human activity could improve the quality of the subterranean habitat. On the other hand, a massive intervention for tourism purposes could seriously jeopardise the survival of the most sensitive species. The increased thermic instability and mean temperature had a significant negative effect on the local populations of cave-dwelling arthropods, whose ecological optimum is determined primarily by low thermic instability, cold temperatures and intermediate conditions of eutrophy. On the basis of our results we strongly recommend to avoid thermic isolation of any part of tunnels, as it is the primary factor affecting the most sensitive species. © 2010 Elsevier GmbH.

Hypogean beetles generally live in stable environments, characterized by constant temperature and high relative humidity. Changes in the underground microclimatic conditions generally induce local migrations of the beetles through the hypogean environment in search of suitable microhabitats. We studied the seasonal dynamics and the micro-climatic preference of two Alpine endemic hypogean beetles Sphodropsis ghilianii (Coleoptera, Carabidae) and Dellabeffaella roccae (Coleoptera, Cholevidae) in the hypogean complex of Pugnetto (Graian Alps, Italy). We surveyed the two species for one year, using baited pitfall traps and measuring temperature and humidity along the two main caves. We used logistic regression mixed models (GLMMs) to relate the presence of the two species to several variables, namely microclimate (seasonality, temperature, and humidity), subjacency and cave length. In addition, we tested the attractive power of the bait on the two species. The thermic optimum for S. ghilianii was found to be around 7°C, with an increasing probability of finding the species in the vicinity of the cave entrance during summer, autumn and spring. The species migrates inside the cave in winter, in response to the drop in the mean daily temperature and in the relative humidity occurring in the outer parts of the cave. On the contrary, D. roccae showed a significant preference for the deeper sections of the cave, characterized by an almost constant temperature of 9°C in air saturated with water vapour. Males and females individuals of both species were found to be equally affected by the environmental variables included in the analysis. We also provided information on the life history of the two species and methodological insights about the use of the bait in the traps. © 2015, Societa Speleologica Italiana. All rights reserved.
