The broad objectives of the International Heteropterists’ Society (IHS) are to promote systematic, biogeographic, and biological studies of Heteroptera and to cultivate cooperative research among heteropterists throughout the world. The Society is organized and operated exclusively for scientific and educational purposes.

The Society holds a meeting every four years at locations around the world, where members give presentations on their work and discuss the directions of the Society. The Society’s website provides an online portal for distribution of information about bugs, including a world bibliography, taxon pages, and membership details.

Interested in joining the IHS? Read more about the Society and information on membership. You can also donate to the Student Travel Fund your contribution is very valuable!

We had an excellent presentation about the next Meeting in Thailand during the last Truebug Tuesday.

Follow the link to our Youtube channel to see it, and do not forget to explore the section about the Meeting. If you have any questions, contact the organizer Bob Sites (bugsinbangkok@gmail.com).

Zhang M., Ren D., & Yao Y. Z.: "Evolutionary development revealed in discovery of the earliest Saldinae (Heteroptera: Leptopodomorpha: Saldidae) in Cretaceous amber from Myanmar".

A new genus and species of shore bugs, Exornatum sulcatum gen. et sp. nov., is identified as the oldest Mesozoic member of the subfamily Saldinae from mid-Cretaceous Kachin amber in Myanmar. This discovery indicates that the Saldinae may have originated in the Cretaceous, a key phase in the subfamily-levels evolutionary radiation of the Saldidae. We also observe and discuss variations in the hemelytra veins of the new and the known species, enhancing our understanding of the early origins and evolution of saldids in the Mesozoic.

Yasunaga T. et al.: "A new species of the orthotyline plant bug
genus Malacocorisella Yasunaga, 1999 (Hemiptera: Heteroptera: Miridae: Orthotylinae) from Thailand".

The third species of the Asian plant bug genus Malacocorisella Yasunaga, 1999 (Orthotylini) is described as new to science from central Thailand. The present discovery of the new species, M. siamica Yasunaga, Oh & Duwal sp. nov., also represents the first distributional record of the genus group from the tropical climatic zone. Habitus images of live individuals and scanning electron micrographs are also provided.

Oliveira J. et al.: "Post-zygotic reproductive barriers confirm absence of continuous interspecific gene flow between Mepraia spp. (Hemiptera, Triatominae)".

Mepraia is a genre composed of three species endemic to Chile. Climate projections demonstrate that these triatomines could modify their potential geographical range and does not rule out that hybridization events could be occurring. Furthermore, recent phylogenomic studies suggested possible ancestral events of hybridization and gene flow and, based on the most recent speciation model that divides Mepraia in two geographically distinct groups (the North, composed of M. garjadoi and M. parapatrica, and the South, composed of M. spinolai), was also suggested an alternative model that may be compatible with ancient hybridization events or continued gene flow. Thus, we conducted a comprehensive study of the capacity to produce hybrids and to reproductive barriers present between Mepraia spp., with the aim of evaluating the possibility of hybridization and interspecific gene flow be occurring in natural conditions and confirming the specific status of the three Mepraia species. Even though hybrids have been obtained in all directions, the combination of different evolutionary events demonstrated here, such as low hatching rate and high mortality rate of hybrids, as well as the presence of post-zygotic reproductive barriers and possible action of Haldane’s rule indicate that there is no continuous interspecific gene flow between Mepraia spp. and confirms the specific status of species based on the biological species concept.
