Motschulsky from Madagascar with descriptions of six new species (Coleoptera, Chrysomelidae, Galerucinae, Alticini).

The revision of the flea beetle genus Motschulsky, 1860 in Madagascar is provided. Six new species are described: , , and from the northern area; , , and from the central area. A new synonym of Weise, 1895 is established: Weise, 1895, , since is shown to be a chromatic form of .

 species-group from sub-Saharan Africa with descriptions of two new species from KwaZulu-Natal (Chrysomelidae, Galerucinae, Alticini).

Heyden is a flea beetle genus with a largely sub-Saharan distribution and currently comprising 34 species. The examination of new material is revealing an increase in species richness and intraspecific variability. and , both from KwaZulu-Natal in the Republic of South Africa, are here described and attributed to the (Jacoby) species group, mainly based on genitalic characters.

Niche overlap and species co-occurrence patterns in carabid communities of the northern Chinese steppes.

Understanding how species sort themselves into communities is essential to explain the mechanisms that maintain biodiversity. Important insights into potential mechanisms of coexistence may be obtained from observation of non-random patterns in community assembly. The spatial niche overlap (Pianka index) and co-occurrence (c-score) patterns in carabid species in three types of steppes (desert steppe, typical steppe, and meadow steppe) in China was investigated.

Molecular and morphological systematics of a new, reef forming, cupped oyster from the northern Arabian Gulf: new species.

The rocky northern shores of Kuwait and those of the western, inner shores of Kuwait Bay are dominated by a small, densely encrusting oyster. The identity of this oyster has never been confirmed and was mistaken previously for a small . The shell morphology suggests that this species belongs to the subfamily Crassostreinae, but within that subfamily, the presence of marginal erect trumpet-shaped projections is so far unique.

(Lucas, 1847) (Coleoptera, Chrysomelidae), a new genus and species for the European fauna.

(Lucas) is an uncommon species of the Galerucini tribe (Coleoptera, Chrysomelidae, Galerucinae) distributed in Algeria, Morocco and Tunisia, and recorded here for the first time for the European fauna. One male and one female were found, not far from each other, wandering on the sand among the vegetation of the shifting dunes of the Tuscan coast (Rosignano Solvay, Spiagge Bianche). Some hypotheses are proposed to explain the presence of on the Italian coast.

Host plant associations in Western Palaearctic flea beetles (Chrysomelidae, Galerucinae, Alticini): a preliminary phylogenetic assessment.

Latreille (Chrysomelidae, Galerucinae, Alticini) is a very large genus of phytophagous insects, with more than 700 species distributed in all zoogeographical regions. Patterns of host use have been a central topic in phytophagous insect research. In this study a first assessment is provided to test the hypothesis that host-plant association is phylogenetically conserved in Western Palaearctic species.

Discovery of a new species of the genus from a groundwater-fed spring in southern France (Crustacea, Copepoda, Harpacticoida, Canthocamptidae).

A new species of the genus Moeschler & Rouch, 1984 (Copepoda, Harpacticoida, Canthocamptidae) is established to accommodate a small canthocamptid population collected from a spring system in the "Parc du Mercantour", Var catchment, southern France. The population analysed in the present study is defined by a set of morphological characters of the female, namely a very large maxilliped, a rudimentary mandibular palp, P1 with 3-segmented exopod and 2-segmented endopod, a falcate terminal claw of the P1 endopod, dorsal seta of caudal rami inserted on the inner margin, and anal operculum not overreaching the insertion of the caudal rami, thus supporting its assignment into the genus . The new species shows marked differences with the nominotypical species of the genus that was originally described by monotypy with the species Moeschler & Rouch, 1984.
