Micatagla hajeki sp. nov., a new species belonging to the genus Micatagla Argaman, 1994, closely related to M. antropovi Pagliano, 2002, is described from specimens recently collected during the Czech entomological expeditions on the island of Socotra. The new species is characterized by uniformly pale red body, with the exception of black terga II–VI and white spurs on legs; and by small lateral teeth of tergum VI distributed regularly on the margins, getting smaller in proximity of the apex. © 2014 Acta Entomologica Musei Nationalis Pragae All rights received.

Storm-petrels usually breed in sites difficult to access, making it hard to estimate the number of individuals in a colony or even the presence of a colony. After several years of study in the main colony and diurnal surveys to other caves of the island, we planned an extensive night survey for identifying previously unknown colonies. In the breeding season of 2011 we found 5 new colonies of storm petrels (Hydrobates pelagicus) at Marettimo island, increasing the estimation of the population on this island to approximately 3000 breeding pairs. We propose the use of mixed methods to locate new colonies, as they can be found by the characteristic smell of storm petrels, but under windy conditions it would be difficult. It is therefore very important to use night surveys to observe night activity by the individuals. © 2012 CISO.

Oxygen (δ18Os) and stable carbon (δ13Cs) isotopic compositions of modern terrestrial gastropod shells from Lipari Island, in the Aeolian Archipelago (Sicily), have been analysed and compared with local meteoric water δ18O (δ18Op) and vegetation δ13C (δ13Cv) respectively. Results reveal that the δ18Os-δ18Op relationship over the study area differs from those obtained on continental Europe and Italian shells, implying that even at the scale of the Mediterranean basin different relationships may co-exist. These differences have been interpreted as the increasing influence of Mediterranean vapour water on Tyrrhenian coasts at relatively low altitude (up to ~600m asl), which compensates for the effect of the δ18Op, and possibly of temperature, on shell δ18O. The steady-state flux balance model (FBM), in agreement with previous studies, suggests that snails are active prevalently at night. Shell carbon isotope ratios reflect the δ13Cv, as predicted by the metabolic model and represent a valuable tool for identifying C3 plants with very distinct isotopic signatures. © 2013 Elsevier B.V.

The present paper provides new data on the mutillid fauna of the Socotra Archipelago (Yemen). The genera Myrmilla Wesmael, 1851, Strangulotilla Nonveiller, 1979, Macromyrme Lelej, 1984, and Dentilla Lelej, 1980 are recorded for the first time. Four new species are described: Strangulotilla dioscoridea sp. nov., Macromyrme bezdeki sp. nov., Dentilla purcharti sp. nov., and Dentilla socotrana sp. nov. On the whole, seven specific taxa have been listed for Socotra Island, two of which inhabit also Samha Island. The archipelago harbours mainly Ethiopian, but also some Palaearctic elements, confirming its significance as crossroad of these biogeographical realms.
