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).

Stefanello F., Carpintero D.L. & Mulieri P.R.: "A new species of Belostoma Latreille (Insecta: Hemiptera: Belostomatidae) from Brazil long-housed at the Museo Argentino de Ciencias Naturales “Bernardino Rivadavia”"

Belostoma utiaritiensis Stefanello sp. nov. (Insecta: Hemiptera: Belostomatidae) is described and illustrated based on a specimen long-housed at the Museo Argentino de Ciencias Naturales “Bernardino Rivadavia”. The specimen was collected in Mato Grosso, central-western Brazil in 1966. This new species is diagnosed by an elevated prosternal keel with apex pointed, article II of labium shorter than III, abdominal pubescence entirely covering the connexiva and mediosternites, dorsal arms of the phallosoma convergent at the apex, and the diverticulum folded at the apex forming an apicoventral protuberance. The new species is assigned to the Belostoma fittkaui species group and compared with its congeners. Additionally, a key to the species of the group is provided. Thus, the number of species of Belostoma recorded from Brazil increases from 49 to 50, from 18 to 19 in the state of Mato Grosso, and from three to four within the B. fittkaui group.

Zhang P. et al.: "A new harpactorin hemipteran insect from the Miocene Dominican amber with fossula spongiosa on all three pairs of legs".

A new genus and species of fossil harpactorin (Hemiptera: Reduviidae), Trispongiosus hui Zhang, Yao, & Liu gen. et sp. nov., is described from Miocene Dominican amber, representing the third fossil record of Harpactorinae. The new species is remarkable for exhibiting fossula spongiosa on all three pairs of legs, which is not only the first report in Harpactorinae but also rare within Reduviidae. This structure is considered to be related to the locomotor capabilities of assassin bugs, potentially enhancing their attachment and agility in navigating complex surfaces and vegetation. Furthermore, the present study suggests that fossula spongiosa exhibits remarkable plasticity within Reduviidae by integrating fossil and extant perspective.

Takeda K. et al.: "Unusual Occurrence of Syncytial Epithelia in the Male Accessory Glands of Shore Bugs (Leptopodomorpha in Hemiptera)".

(1) Background: The insect male accessory gland (MAG) produces seminal fluid components crucial for male reproduction, analogous to the mammalian prostate. While some insect MAGs exhibit binucleate epithelial cells for luminal volume plasticity, the diversity of cellular arrangements and their functional implications across insects remain largely unknown. (2) Methods: We investigated the cellular architecture of MAG epithelia in various shore bug species (infraorder Leptopodomorpha, Hemiptera) and their mechanisms of multinucleation and potential MAG volume regulation. (3) Results: The MAG epithelia of shore bugs comprise a small number of large, plastic syncytial cells with varying nuclear numbers. We hypothesize that these syncytia facilitate effective MAG volume expansion post-eclosion. Uniquely, MAG shrinkage involves the localized contraction of limited muscle fibers, unlike the systematic contraction of circular muscles in most other insects. We further describe sequential cell fusion during the nymphal stage as the mechanism of multinucleation. (4) Conclusions: The unique syncytial organization of Leptopodomorpha MAG epithelia represents an evolutionary divergence from typical binucleate or mononucleate structures in other insects; it is likely that this enables distinct mechanisms for reproductive fluid storage and evacuation. This study highlights the evolutionary diversity of male reproductive organ morphology and function within insects.
