The aquatic insect fauna of salt marshes is poorly characterized, with the possible exception of biting Diptera. Aquatic insects play a vital role in salt marsh ecology, and have great potential importance as biological indicators for assessing marsh health. In addition, they may be impacted by measures to control mosquitoes such as changes to the marsh habitat, altered hydrology, or the applic...

Hydrometra sapiranga sp. nov. is described, illustrated, and compared with similar species. An identification key to the species of Hydrometra recorded from Brazil is also presented.

Megadrymus brigalow n. sp., a new species of seed bug, is described from semi-evergreen vine thicket in the Brigalow Belt region of Queensland, Australia. This species has the smallest body in the genus Megadrymus Gross and has a number of vestigial characters.

The neotropical genus Alkindus Distant is revised based on morphological characters (general morphology, including the external scent efferent system and leg structures, and external genital morphology). The male of Alkindus crassicosta Horvath is here described for the first time. Illustrations, an adapted key to species, and a compiled list of plants associated with both species are provided....

To date, only the type species Lissonotocoris membranaceus Usinger & Matsuda 1959 is known and recorded from Vietnam and China, Hainan Island. Four new species of the previously monotypic genus Lissonotocoris are described and figured: loebli n.sp. (Thailand), glabronotus n.sp. (N.Vietnam), pachycerus n.sp. (Malaysia) and siamensis n.sp. (Thailand). A key for the identification of all 5 species...

The species diversity of Pyrrhocoridae is cataloged in this paper. Seven species (from three genera: Aderrhis Bergroth 1906, Pyrrhocoris Fallén 1814, Scantius Stål 1866) are given as the fauna of Iran.

The genus Rhagovelia Mayr, 1865 is distributed worldwide, especially in the Tropics, and contains 184 species in the Americas, which are listed and included in complexes or grades, and in 18 species groups. Geographical distributions and altitudinal ranges are presented for each species. A new synonym is proposed, and some biogeographical aspects of the genus are analyzed, such as its distinct ...
