A multidimensional characterization of rarity applied to the Aegean tenebrionid beetles (Coleoptera Tenebrionidae)

This paper attempts to use museum collection data to estimate measures of species rarity and then to relate these measures to extinction risk. For this purpose, 170 taxa (138 species and 32 subspecies) of tenebrionid beetles from 32 Aegean Islands (Greece) were considered. For each taxon, rarity was evaluated as geographic distribution (mean incidence on islands in the archipelago), potential habitat exploitation (total area of the islands occupied on the total area of the study system) and contactability (number of decades of taxon’s records on the total number of decades of assumed persistence from 1870 to 2000). All of these indices were correlated to each other. Whether expressed in terms of range size or habitat exploitation rarity was a major determinant of a species’ risk of extinction (evaluated as extinction decade). Thus, the designation of rarity provides a good basis for identifying species that are most in need of conservation at a particular scale.     

Climatic correlates of body size in European tenebrionid beetles (Coleoptera: Tenebrionidae)

Tenebrionidae are one of the largest families of beetles and are known for their adaptations to hot and dry climates. An increase in body size also increases the volume/surface area ratio, which reduces transpiration, and hence water loss. If an increase in body size is an important adaptation in tenebrionids to cope with increasing aridity, we expect a correlation between body size and climatic gradients in the major tenebrionid clades. Alternatively, we can postulate that arid climates do not drive body size evolution, but rather select, from a wider fauna containing species of any size, those that have larger bodies. In this case we expect that drier regions will host faunas that contain, on average, larger species. To test the first hypothesis, we correlated inter-specific body size variation in the main tenebrionid clades with climatic gradients in Europe. We found only weak trends. To test the second hypothesis, we regressed mean body size of European country faunas against climatic characteristics. We found a strong increase in body size in southern faunas experiencing hot and dry climates. Therefore, increase in body size is not a major adaptation in tenebrionid evolution, but climate is an important filtering factor that determines a prevalence of larger species in southern Europe.     

New data on the ground-beetle fauna (Coleoptera,Carabidae) of the Sikhote-Alin Mountains

Pterostichus kajimurai Habu et Tanaka, 1957 new for the fauna of Russia and Perigona nigriceps (Dejean, 1831) and Amara distinguenda A. Morawitz, 1862 both new for the fauna of the Sikhote-Alin Mountains are described. The following new synonymies are proposed: Carabus careniger Chaudoir, 1863 (= C. careniger victorianus Obydov, 1997, syn. n.) and C. gossarei vasjurini Lafer, 1989 (= C. gossarei venustoides Deuve, 1990).

The ground beetle fauna (Coleoptera,Carabidae) of Southeastern Altai

Long-term studies of the ground beetle fauna of Southeastern Altai (SEA) revealed 33 genera and 185 species; 3 and 15 species are reported for the first time from Russia and SEA, respectively. The following genera are the most diverse: Bembidion (47 species), Amara and Harpalus (21 each), Pterostichus (14), and Nebria (13). The subarid (35%) and boreal (32%) species prevail in the arealogical spectrum, while the mountain endemics comprise 13% of the fauna. The carabid fauna of SEA is heterogeneous in composition and differs significantly from that of the Western and Central Altai. The boreal mountain component mostly comprises tundra species with circum-boreal or circum-arctic ranges, while the subarid component (typical Mongolian together with Ancient Mediterranean species) forms more than one-half of the species diversity in the mountain basins. The species diversity increases from the nival mountain belt (15 species, predominantly Altai-Sayan endemics) to moss-lichen tundras (40, mostly boreal, species). The variety of habitats and constant hydrothermal regimes in the intrazonal valley communities determine high taxonomic diversity of Carabidae, including both tundra or meadow-steppe species typical of the region and some forest ones. Under the condition of moisture deficiency, many steppe species also concentrate in river floodplains.     

New species of the tenebrionid genus <Emphasis Type="Italic">Menimus</Emphasis> sharp, 1876 (Coleoptera,Tenebrionidae) from southern Palaearctic

Three new species of the genus Menimus are described from Yunnan Province, China. Over 70 species of Menimus are distributed in the tropical and subtropical zones from India to Oceania and New Zealand. A new subgenus, Sinomenimus subgen. n., is erected with the type species M. kabaki sp. n. characterized by the absence of eyes and by the presence of the spermatheca and sharp depression at the posterior margin of the thoracic metasternite. The following new synonymy is established: Menimus Sharp, 1876 = Neomenimus Kaszab, 1939, syn. n., with the following new combinations resulting: Menimus clavatus (Kaszab, 1939) = Neomenimus clavatus Kaszab, 1939, comb, n.; Menimus biroi (Kaszab, 1939) = Neomenimus biroi Kaszab, 1939, comb, n.; Menimus setosus (Kaszab, 1939) = Neomenimus setosus Kaszab, 1939, comb, n.; Menimus brevissimus (Kaszab, 1939) = Neomenimus brevissimus Kaszab, 1939, comb. n.     

Stag beetle fauna of Cambodia (Coleoptera: Lucanidae)

To date, no species catalogue of stag beetles (Lucanidae) has been compiled for Cambodia. According to the available literature, we assembled the checklist based on the previously recorded and recognized Cambodian lucanid species in the country. In the present paper, we newly record four species from Cambodia: Falcicornis axisopsis (Séguy, 1954); Neolucanus similis Bomans & Ratti, 1976; Prosopocoilus suturalis (Olivier, 1789); and Prosopocoilus jenkinsi (Westwood, 1848). An updated checklist of the Cambodian stag beetles is given. The total number of the Cambodian lucanid species has now reached 29, but this species count is considerably less diverse than those in neighboring countries. Our study suggested that this poor diversity is not primarily due to biogeography or small country size but to a lack of research effort.     

Endemism patterns in the Italian leaf beetle fauna (Coleoptera,Chrysomelidae)

In this contribution the results of a zoogeographical analysis, carried out on the 123 endemic leaf beetle species (Coleoptera: Chrysomelidae) occurring in Italy and its immediately adjacent regions, are reported. To assess the level of faunistic similarity among the different geographic regions studied, a cluster analysis was performed, based on the endemic component. This was done by calculating the Baroni Urbani & Buser’s similarity index (BUB). Finally, a parsimony analysis of endemicity (PAE) was used to identify the most important areas of endemism in Italy.     

Ten new species of the tenebrionid genus <Emphasis Type="Italic">Asidoblaps</Emphasis> fairmaire (Coleoptera,Tenebrionidae) from southwestern China
