Ochterus santosi sp. nov., from the state of Piauí, northeastern Brazil, is described, illustrated, and compared with other species of the genus from the Americas. An identification key to the species recorded from the country is also presented.
Two new Vertomannus species, Vertomannus flavus sp. n. (south Vietnam) and Vertomannus borneensis sp. n. (Borneo) are described. Vertomannus (Elongatomannus), subgen. n. (type species: Vertomannus flavus) is proposed.
Voltinism in Microvelia hinei was studied in southern Illinois during 1989 and 1990. This species apparently overwintered as adults, which became active in late April; adults were last collected in late September. First instars were found from mid-May to late June, second instars from early-May to late October, third instars from mid-May to mid-July, fourth instars from mid-May to mid-August, a...
The patterns of mating and possible factors influencing mate choice in the consperse stink bug, Euschistus conspersus Uhler, were studied in a series of laboratory experiments. Males were found to transfer a significant percentage of their body mass during the initial mating. Mating was also found to reduce male longevity by 37.8% but had no significant effect on female longevity or fecundity. ...
Thestral incognitus, new genus and species of Pentatomidae (Pentatominae: Carpocorini) is described from central Chile. The relationships among this new genus and other South American genera are discussed. Also, similarities are noted between Thestral and the Australian genus Poecilotoma. Poecilotoma is tentatively placed in the Carpocorini. A key to aid in the recognition of the genera of Chi...
Sinopla humeralis Signoret, 1864 is revalidated and removed from the synonymy of Sniploa obsoletus Signoret, 1864. The first formal records from it original description and first data about its biology are provided. The type species of the genus Sinopla is discussed and the concept of the genus is expanded. The association of Sinopla humeralis with the southern beech Nothofagus Blume and it dis...
Rhagovelia zecai sp. nov., from the Brazilian Amazon, is described, illustrated, compared with similar species, and included in a key to species of the robusta group recorded from the country.
Global warming may affect species abundance and distribution, as well as temperature-dependent morphometric traits. In this study, we first used historical data to document changes in Orius (Heteroptera: Anthocoridae) species assemblage and individual morphometric traits over the past seven decades in Israel. We then tested whether these changes could have been temperature driven by searching f...
The Japanese species of the heterogastrid genus Sadoletus Distant are revised taxonomically. Three species are recog-nized, including a new species, S. ryukyuensis sp. nov., which has been regarded so far as S. valdezi Bergroth in Japan. "True" S. valdezi is confirmed in Japan as well. A key to the Japanese species is provided.
