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 ...

The monotypic genus Horciniella Miller, 1958 is considered a junior synonym of Archilestidium Breddin, 1900 (new synonymy), resulting in the following taxonomic change for its type species: Archilestidium variabile (Miller, 1958) (new combination). The evidence supporting this conclusion and the new composition of the genus are discussed at length. Updated keys to the reduviine genera of Austra...

A new stenopodaine reduviid, Aulacogenia darjeelingensis sp. nov. belonging to the "corniculata species group" from India is described and illustrated. A key to the Indian species of the genus Aulacogenia Stål is provided. 

Two new species of the genus Aphelocheirus (Hemiptera: Heteroptera: Aphelocheiridae), A. longlingensis sp. nov. from Yunnan and A. motuoensis sp. nov. from Xizang (Tibet) Autonomous Region are described in this paper. A. similaris Polhemus & Polhemus, 1989, A. nawae Nawa, 1905 and A. tuberculipes Zettel & Tran, 2009 are reported from China for the first time. A key to Chinese species of Apheloc...

A new species of Dichelops (Diceraeus) Dallas and the so-far unknown male of Dichelops (Prodichelops) divisus (Walker, 1867) are described, based upon morphological characters. D. (Dice.) caatinguensis sp. nov. is compared to the other four species of Diceraeus. Revised keys to separate the subgenera of Dichelops and the species of Diceraeus are also presented. D. (P.) divisus male is described...

The pudibunda group of Edessa is here proposed to include Edessa pudibunda Stål, 1862, Edessa picticornis Stål, 1872, Edessa godmani Distant, 1881, Edessa punctata Santos & Fernandes sp. nov., Edessa luteomaculata Santos & Fernandes sp. nov., Edessa nigriventris Santos & Fernandes sp. nov. and Edessa nigridorsata sp. nov. This group is restricted to Central America. Descriptions, measurements a...
