Spiders are powerful predators, but the threats confronting them are numerous. A survey is presented of the many different arthropods which waylay spiders in various ways. Some food-specialists among spiders feed exclusively on spiders. Kleptoparasites are found among spiders as well as among Mecoptera, Diptera, Lepidoptera, and Heteroptera. Predators are found within spiders’ own population (c...

Doesburgella gen. nov. and its type species D. dilatata sp.nov (Hemiptera, Heteroptera: Reduviidac, Phymatinae; Macrocephalini) are described from South Africa.

An updated checklist of the New Zealand Heteroptera (Insecta: Hemiptera) is provided as a supplement to the "Heteroptera (Insecta: Hemiptera): catalogue" of Larivière and Larochelle (2004: Fauna of New Zealand 50). A total of 142 genera and 319 species belonging to 28 families are recorded for New Zealand. Changes to the 2004 catalogue are documented. The synonymy and primary type information o...

Kokeshia xiei sp. nov. and K. zhengi sp. nov. (Hemiptera: Heteroptera: Dipsocoromorpha: Schizopteridae) are described from Hainan and Hubei Provinces of China, respectively.

Heteroptera, or true bugs, are the largest, morphologically diverse and economically important group of insects with incomplete metamorphosis. However, the phylogenetic relationships within Heteroptera are still in dispute and most of the previous studies were based on morphological characters or with single gene (partial or whole 18S rDNA). Besides, so far, divergence time estimates for Hetero...

In 2018 and 2019, quantitative aquatic macroinvertebrate samplings were carried out in the river network of Bükkösdi-víz (Mecsek Mountain). The identification 325,865 specimens originated from 40 sampling sites resulted occurrences 125 different species belonging to 12 higher taxa (Gastropoda – 9, Bivalvia 1, Hirudinea 4, Malacostraca 6, Ephemeroptera 16, Odonata 12, Plecoptera 3, Heteroptera 1...

Insects of the suborder Heteroptera are known for their odor, for being pests, or for being disease carriers. To gain better insight into the cytogenetic characteristics of heteropterans, 18 species of terrestrial Heteroptera belonging to eight families were studied. The presence of heteropycnotic corpuscles during prophase I, terminal or interstitial chiasmas, telomeric associations between ch...

A host may be physically isolated in space and then may correspond to a geographical island, but it may also be separated from its local neighbours by hundreds of millions of years of evolutionary history, and may form in this case an evolutionarily distinct island. We test how this affects the assembly processes of the host's colonizers, this question being until now only invoked at the scale ...

The order Hemiptera was formerly divided into two suborders, Heteroptera and Homoptera. The suborder Homoptera was also divided into two convenient groups, the Auchenorrhyncha and the Sternorrhyncha, the latter comprising the superfamilies Aphidoidea, Psylloidea, and Aleyrodoidea, plus the scale insects in the superfamily Coccoidea. Until about the mid-20th century, most workers on scale insect...

morphometric differentiations may explain biogeographic distinctions among populations of a given species. the possibility of morphometric distinctions between two populations of eurygaster maura l. collected from the northeast (golestan province) and the northwest (azarbayejan province) of iran was examined using principal component analysis over 25 body measurements (eight absolute and 17 pro...
