A new species, Atractosomus amazonicus sp. nov. is described and three species, A. robustus Candeze, 1859, A. carinatus Candeze, 1859 and A. conicicollis Candeze, 1859 are redescribed and ...illustrated. A comparison among these species and with the type-species, A. flavescens (Germar 1839) is presented. A. amazonicus sp. nov. and A. robustus belong to group of species with 3 super(rd) and 4 super(th) antennomeres equal in size and the other studied species, to group with 3 super(rd) antennomere smaller than 4 super(th).Original Abstract: Uma especie nova, Atractosomus amazonicus sp. nov. e descrita e tres especies, A. robustus Candeze, 1859, A. carinatus Candeze, 1859 e A. conicicollis Candeze, 1859 sao redescritas e ilustradas. E apresentada a comparacao entre essas especies e com a especie-tipo do genero, A. flavescens(Germar 1839). A. amazonicus sp. nov. e A. robustus pertecem ao grupo de especies com 3 degree e 4 degree antenomeros iguais cm comprimento e as demais especies estudadas, ao grupo de especies com 3 degree antenomero menor que o 4 degree .
This article present new faunistic data of a very rare click-beetle Oxynopterus harmseni Candèze, 1885 in Sumatra, Indonesia. Photographs of the habitus and the aedeagus are provided. fauna, ...click-beetles, Elateridae, Oxynopterus, Indonesia.
Economically important species of wireworms (Coleoptera: Elateridae) were successfully associated with adults using cytochrome oxidase I (COI) barcoding, proving the usefulness of this technique to ...associate life stages in taxonomically difficult pest groups. Previously unrecognized and morphologically difficult, even indistinguishable, pest larvae were shown to be identifiable using this technique. This is a critical step toward discovering effective species-based integrated pest management strategies for this resurgent pest group following the loss of Lindane seed treatments. Three new adult-larval associations were discovered for Hadromorphus callidus (Brown), Hemicrepidius carbonatus (LeConte) and Metanomus insidiosus (LeConte). Hypnoidus bicolor (Eschscholtz) was shown to comprise multiple divergent lineages at a level usually considered different species, indicating that the population structure of some pest species requires more investigation. The status of the prairie grain wireworm, Selatosomus destructor (Brown), as a full species or as a subspecies of Selatosomus aeripennis (Kirby) is called into question.
The genus Agrypnus Eschscholtz, 1829 (Coleoptera: Elateridae) and the species A. murinus (Linnaeus, 1758) are recorded for Mongolia for the first time. This species is widely distributed in the ...Palaearctic, mainly in Euro-Siberian region. Two specimens of A. murinus were collected in northeastern Mongolia (Töv Province), which is probably the southeasternmost border of the species range.
Biodiversity of Elateridae in three forest types, i.e., larch plantations (Larix kaempferi (Lamb.) Carriere), secondary forest, and primary forest, was investigated and compared. Click beetles were ...captured with malaise traps in 46 stands in three 14-d periods in June, July, and August. A total of 550 individuals, representing 53 species of click beetles, were captured for this study. The number of species and the number of individuals were not significantly different among the three forest types. However, the composition of species in the three forest types was different. The 46 stands were divided into three groups that were approximately equivalent to the three forest types by Twinspan analysis. Elaterid species associated with the primary forest was Dalopius exilis Kishii. Selatosomus puerilis Kishii and Hemicrepideus secessus secessus Candeze were specific to the secondary forest, and Hemicrepidius sinuatus sinuatus (Lewis) and Ampedus optabilis optabilis (Lewis) showed their preference for the larch plantation. In environmental factors investigated, openness of the canopy influenced the number of the species.
