Nine extinct species and one genus of aderid beetles (Coleoptera: Tenebrionoidea: Aderidae) are described from Baltic and Bitterfeld amber from Germany, Russia (Kaliningrad), Poland, and Denmark. These new species include: Escalerosia igori sp. nov., Picemelinus irinae sp. nov., Vanonus ulmerigicus sp. nov., Vanonus aestiorum sp. nov., Cnopus kraxtepellenensis sp. nov., and four species from th...

Two new species of Silphitrombium Fain, 1992 (Acari: Prostigmata: Neothrombiidae), ectoparasites of beetles (Insecta: Coleoptera), are described from Sistan and Baluchestan Province, eastern Iran: S. elateridum sp. nov. on Heteroderes heideni Reitter, 1891 (Col.: Elateridae) and S. iranicum sp. nov. on Opatroides punctulatus Brullé, 1832 (Col.: Tenebrionidae) and the genus Silphitrombium is red...

In the order Coleoptera, cantharidin is produced by two families, Meloidae (true blister beetles) and Oedemeridae (false blister beetles). Cantharidin is of veterinary and medical importance, since it is super toxic to animals and humans. The present work was conducted aiming to review the cantharidin investigation and cantharidin toxicosis to animals including pathology, symptomatology, preven...

The Neotropical genus Cephaloleia Chevrolat (Coleoptera: Chrysomelidae: Cassidinae) includes 214 species distributed from the south of Mexico to Argentina. Cephaloleia beetles feed mostly on plants from the order Zingiberales. The interactions between Cephaloleia beetles and their Zingiberales host plants is proposed as one of the oldest and most conservative associations. Here we describe a ne...

A new flea-beetle species, Crepidodera svetlanae sp. nov. (Coleoptera: Chrysomelidae: Galerucinae: Alticini) is described and illustrated from the Baltic amber. The new species is compared with the fossil and recent species of the genus. A key to species of flea beetles known from fossil resin is provided.

A new species of flanged bombardier beetles is described from Jiangxi and Sichuan, China, Paussus (Scaphipaussus) zhouchaoi sp. n. (Coleoptera, Carabidae, Paussinae, Paussini). All the type specimens were collected from colonies of the host ant Pheidole sp. (Hymenoptera, Formicidae, Myrmicinae). Important morphological characters of the new species are illustrated by color plates.

The majority of terrestrial biomass is wood, but the elemental composition of its potential consumers, xylophages, differs hugely from that of wood. This causes a severe nutritional imbalance. We studied the stoichiometric relationships of 11 elements (C, N, P, K, Ca, Mg, Fe, Zn, Mn, Cu, Na) in three species of pine-xylem-feeding insects, Stictoleptura rubra, Arhopalus rusticus (Coleoptera, Cer...

The extinct representatives of family are known from the Upper Cretaceous (the Turonian: Pseudocuphosis tristis Nikitsky, 2002 and Archaeserropalpus cretaceus Nikitsky, 2002; the Cognac-Santonian: Archaeoxylita zherichini Nikitsky, 1977). Melandryid beetles are also known from Eocene ambers of Europe. One species was described from Ukrainian amber (Orchesia rasnitzyni Nikitsky, 2011). At least ...

An annotated taxonomic catalogue of the jewel beetles (Coleoptera: Buprestidae) of Iran is given. Original descriptions and recent revisionary or catalogue data are included along with the distribution, both within and outside of Iran, ecological data and host plant associations, junior synonyms, and comments. A complete bibliography completes the catalogue. In total 428 species and 52 subspeci...

Nineteen species of seed-beetles belonging to the subfamily Bruchinae (Coleoptera, Chrysomelidae) were collected in Xinjiang, China. Of these, the following four were new records for China: Bruchusaffinis Frolich, 1799, Bruchusatomarius L., 1761, Bruchusloti Paykull, 1800 and Kytorhinuskergoati Delobel & Legalov, 2009. We provide an annotated checklist, illustrations and a key to the 19 species.
