A basic knowledge of regional faunas is necessary to follow the changes in macroinvertebrate communities caused by environmental influences and climatic trends in the future. We collected all the available data on water bugs in Hungary using an inventory method, a UTM grid based database was built, and Jackknife richness estimates and species accumulation curves were calculated. Fauna compositi...

Two new species of Papeocoris are described from Peru, P. nitens sp. nov. and P. vittatus sp. nov. A key to species is provided together with dorsal view photographs.

Insect drift on shore of lakes and seas is a relatively common phenomenon although apparently not frequently reported in the literature. Here we review the worldwide occurrence of insect drift with emphasis on Heteroptera, and speculate on possible causes to explain such phenomenon. The dramatic drift of millions of specimens of the pentatomid Mayrinia curvidens (Mayr) on the shore of the south...

The authors propose a new synonym between Collaria scenica (senior synonym) and Collaria columbiensis (junior synonym) based on external morphology and genitalia characteristics of male and female adults of both species. There was no significant difference found to believe that they are two different species.

Mesothoracic wings have been examined and compared in 32 species representing 20 genera of Afrotropical Scutelleridae. Morphological characters of the corium are described. Three main types of mesothoracic wing venation patterns can be recognized. The taxonomic significance of forewing characters in Scutelleridae is briefly discussed.

Ten new species of Rhagovelia are described from Colombia as follows: Rhagovelia penta sp. n., and Rhagovelia santanderi sp. n., from the Upper and Middle Magdalena River Valley respectively; Rhagovelia carina sp. n., Rhagovelia tricoma sp. n., and Rhagovelia barbacoensis sp. n., from Altaquer, Río Ñambi; Rhagovelia caunapi sp. n. from Río Caunapi; Rhagovelia tumaquensis sp. n., from Tumaco, Rí...

The assassin bugs of the genus Acanthaspis Amyot & Serville (Reduviinae) from China are revised. Fourteen species are recognized, described or redescribed and illustrated. Three species, A. fulviconnexa, A. melanota, and A. octoguttata, are described as new to science. Acanthaspis subinermis Hsiao 1976 is synonymized with A. laoensis Distant 1919. A key for the identification of Chinese species...
