Eucamaragnathus desenderi, a new ground beetle species from Africa (Coleoptera, Carabidae)  [cached]
Thorsten Assmann,Claudia Drees,Andrea Matern,Andreas Schuldt
ZooKeys , 2011, DOI: 10.3897/zookeys.100.1521
Abstract: Eucamaragnathus desenderi sp. n., a new ground beetle species of the tribe Hiletini, is described from eastern and southern Africa and dedicated to the recently deceased Belgian carabidologist Konjev Desender. The new taxon is known so far from localities in Zambia (Mukuku, southeast of Mansa) and in South Africa (Bothaville, south of Klerksdorp). The new species belongs to the E. castelnaui group and is characterized by shape of pronotum, smooth or sparsely punctate pronotal transverse impression, characters of male genitalia and elytral striae continued to the apex. Illustrations of the habitus, the median lobe and its internal sac and several other morphological features are presented. An updated identification key to the African Eucamaragnathus species is given.

Heavy metals in carabids (Coleoptera, Carabidae)  [cached]

ZooKeys , 2011, DOI: 10.3897/zookeys.100.1529
Abstract: Carabid beetles (Coleoptera, Carabidae) are one of the most studied soil groups in relation to heavy metal (HM) accumulation and use for bioindication of environmental pollution. Accumulation of Zn and Cu in carabid beetles was species-, sex- and trophic group-specific. No differences were found in HM contents between omnivorous and carnivorous species. The use of carabid beetles as indicators of HM accumulation appears to be rather limited.

Abstract: The article presents the role and the place of soil beetles (Coleoptera: Carabidae, Scarabaeidae, Elateridae, Tenebrionidae) - pests of agricultural crops in agro-ecosystems and their study, collection, identification of species composition and distribution of the plants in the Republic of Dagestan
Journal of Central European Agriculture , 2006,
Abstract: The researches were made during 1992-2001. There were collected 10704 specimens of carabidaes (Coleoptera- Carabidae). The species with the largest number of collected specimens were: Pseudophonus rufi pes, Harpalus distinguendus, Pseudophonus griseus, Brachynus explodens, Brachynus crepitans and Amara familiaris.
New records of myrmecophilous beetle Paussus turcicus (Coleoptera, Carabidae) in Southeastern Balkans  [PDF]

ZooNotes , 2011,
Abstract: The rare myrmecophilous beetle Paussus turcicus I. Frivaldszky von Frivald, 1835 (Coleoptera, Carabidae) is reported in three new localities in Bulgaria and one in the European part of Turkey. It has been found in nests of the typical ant host Pheidole pallidula (Nylander, 1849) (Hymenoptera, Formicidae). It is reported for first time from Sakar and Eastern Rhodope Mountains in Bulgaria.
What do we know about winter active ground beetles (Coleoptera, Carabidae) in Central and Northern Europe?  [cached]

ZooKeys , 2011, DOI: 10.3897/zookeys.100.1543
Abstract: This paper summarizes the current knowledge on winter active Carabidae in Central and Northern Europe. In total 73 winter active species are listed, based on literature and own observations. Ground beetles are among the three most numerous Coleoptera families active during the autumn to spring period. The winter community of Carabidae is composed both of larvae (mainly autumn breeding species) and adults, as well as of epigeic species and those inhabiting tree trunks. Supranivean fauna is characterized by lower species diversity than the subnivean fauna. The activity of ground beetles decreases in late autumn, is lowest during mid-winter and increases in early spring. Carabidae are noted as an important food source in the diet of insectivorous mammals. They are also predators, hunting small winter active invertebrates.
Distribui??o de Carabidae e Staphylinidae em agroecossistemas
Cividanes, Francisco Jorge;Santos-Cividanes, Terezinha Monteiro dos;
Pesquisa Agropecuária Brasileira , 2008, DOI: 10.1590/S0100-204X2008000200001
Abstract: the objective of this work was to determine the distribution of species richness and habitat preference of carabidae and staphylinidae (coleoptera) in two areas cultivated with soybean/corn under no-tillage and conventional tillage systems and in adjacents areas with forest fragment and a pinus stand, respectively. beetles were sampled by pitfall traps which were distributed in two transects of 100 m. the distribution of species richness in the crops and forest fragment/pinus was evaluated by regression analysis. cluster analysis was used to identify species in relation to preference for the forest fragment, pinus, crop and interface. the distribution of carabidae and staphylinidae species richness did not show variation in relation to the position in transect, while the species richness observed in the interfaces between forest fragment or pinus stand and crops were higher compared with the ones found in other habitats. the occurrence of carabidae species differed in relation to the vegetation type: megacephala sp. and scarites sp. preferred crop areas under soybean/corn rotation system. the same was observed with odontochila nodicornis (dejean) in the forest fragment and pinus stand. the species abaris basistriatus chaudoir was characterized as a generalist species in relation to habitat preference.
New or little-known species of the genus Amphimenes Bates, 1873 (Coleoptera, Carabidae, Lebiinae) from Vietnam  [cached]

ZooKeys , 2010, DOI: 10.3897/zookeys.65.503
Abstract: Twelve new species of the genus Amphimenes Bates, 1873 are described from Vietnam: Amphimenes maculatus, sp. n., Amphimenes bidoupensis, sp. n., Amphimenes gracilis, sp. n., Amphimenes montanus, sp. n., Amphimenes giganteus, sp. n., Amphimenes medius, sp. n., Amphimenes minutus, sp. n., Amphimenes rufipes, sp. n., Amphimenes reflexicollis, sp. n., Amphimenes planicollis, sp. n., Amphimenes nitidus, sp. n., and Amphimenes kabakovi, sp. n.. Amphimenes rugulipennis Bates, 1892, comb. n., is transferred from the genus Brachichila Chaudoir, 1869 and is redescribed from fresh material. A key to all congeners is provided, these being arranged into five new species-groups. Adults of the rugulipennis- and piceolus-groups show subcortical habits, while those of the medius-, rufipes- and planicollis- groupsare herpetobiotic, resulting in such morphological adaptations as partly reduced eyes, missing wings and adnate elytra.
Una especie nueva de Trechisibus de la Argentina (Coleoptera: Carabidae)
Roig-Ju?ent,Sergio; Sallenave,Soledad;
Revista de la Sociedad Entomol?3gica Argentina , 2005,
Abstract: abstract. trechini is a tribe of carabidae (coleoptera) widely distributed in the andean patagonian region in south america. in spite of several partial revisions of the tribe for argentina and chile, it is very common to find new species due to the research of unexplored areas. in the present paper, a new species of the genus trechisibus jeannel from the cerro nevado (mendoza, argentina) is described. based on its morphological features the new species is considered as a member of the depressus group. the adult of the new species is described and illustrated, a key for the identification of the species of the depressus group is provided, and some aspects of the distribution of the group are discussed.
