DUE TO A DIVERSITY OF HABITATS AND ITS GEOLOGIC HISTORY, THE US STATE OF CALIFORNIA HOSTS A SPECTACULAR ASSEMBLAGE OF DARKLING BEETLE SPECIES (COLEOPTERA: Tenebrionidae). In addition to being part of the California Floristic Province, one of 34 global biodiversity hotspots identified by Conservation International, California also has additional areas which are parts of the Great Basin, Mojave, ...

Introduction Associations between bark beetles (Coleoptera: Curculionidae: Scolytinae, or family Scolytidae, depending on the classification used, Bright 1993; Marvaldi et al. 2002) and fungi are varied and well known, but mycophagy (fungal feeding) by bark beetles has received relatively little attention. This may be due to the rarity or relative unimportance of fungal feeding by bark beetles,...

The overabundance of large herbivores is now recognized as a serious ecological problem. However, the resulting ecological consequences remain poorly understood. The ecological effects of an increase in sika deer, Cervus nippon Temminck (Cervidae), on three insect groups of beetles was investigated: ground beetles (Carabidae), carrion beetles (Silphidae), and dung beetles (Scarabaeidae and Geot...

The first detailed specimen records are presented for the Australian beetle Homotrysismacleayi (Borchmann, 1909) in New Zealand. Evaluation of this evidence clearly indicates that the species is fully established in the wild in New Zealand. It is therefore recommended that the species be added to the New Zealand Organisms Register (NZOR), as exotic and present in the wild. Some general comments...

Onymacris brainei Penrith, 1984 - the most recent species of Onymacris to be described - is known only from its type locality in the Namib Desert, adjacent to the Cunene River in northern Namibia. No additional specimens are known to have been collected beyond the type series. Herein, we report on eight specimens discovered at a second site near the original locality. DNA from four beetles was ...

Three new species of Gnaptorina Reitter, 1887, G (Hesperoptorina) medvedevi, sp. nov., G (H.) dongdashanensis, sp nov. and G (H.) cuonaensis, sp. nov. are described from Tibet, China. A key to the known species of the subgenus Hesperoptorina is given.

Tenebrionidae is a diverse insect family of Coleoptera that shows high levels of endemicity in epigean species. For the Andean region, which is divided into three subregions: Central Chilean, Subantarctic and Patagonian, it has been hypothesized that epigean tenebrionids have diversified in the Patagonian subregion and subsequently, they dispersed to Subantarctic and Central Chilean subregions....

Callyntra Solier, 1836 is a genus mainly from Chile, with one species occurring in Argentina, which currently contains 20 described species. Recent explorations in the Andes Mountain Range in Chile, have resulted in the collection of specimens morphologically different from all previously described species. The aim of this paper is to describe a new species of Callyntra, discuss its relationshi...

ptinidae or spider beetles, is a worldwide family of beetles especially distributed in the subtropical and temperate zones including iran. niptus holoeucus (golden spider beetle) from kangohar cave in fars province (iran) is described as new record for iran. we regarded this beetle as a troglophile and guanophile species.

The Colorado potato beetle, Leptinotarsa decemlineata (Say), is one of the most damaging insect pests of potato, Solanum tuberosum L. Novaluron is a relatively new benzoylphenyl urea insect growth regulator with good activity against this pest. Earlier studies revealed that feeding on potato foliage treated with novaluron induces reversible egg hatch inhibition in adult Colorado potato beetles....
