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).

New paper!

Kim J. et al.: "The genus Tinginotum Kirkaldy, 1902 (Hemiptera, Miridae, Mirinae) with description of a new species from Vietnam and additional notes on Southeast Asian materials".

The plant bug genus Tinginotum Kirkaldy is reviewed from Vietnam. Four species are recognized, including a new species, Tinginotum linhi Kim, Chérot & Jung, sp. nov., and new distributional records of T. bilineatum and T. perlatum from Vietnam. Detailed diagnoses, descriptions, and a key to the Vietnamese species are provided. Male and female genitalia of T. bilineatum and female genitalia of T. knowlesi are described and illustrated for the first time. In addition to reviewing the Vietnamese fauna, distributional records from neighboring countries were also examined, leading to updated occurrence data for the genus. A particular focus is given to the potential broad-range distribution of T. perlatum, considering whether this pattern reflects a truly widespread species or unresolved conspecificity with taxa described from tropical regions. Furthermore, for several Southeast Asian species that were described long ago, the early 19th century, but remain poorly known, we provide photographs of the type specimens and summarize the essential key characters based on the images examined and the original descriptions. These notes are intended to encourage future comprehensive taxonomic research on the genus and its related taxa.

Bloesch Z. et al.: "Phenology of Kleptobiotic Sundew Bugs Tracks Peak Stickiness of Their Carnivorous Host Plants".

Drosera L. (Droseraceae) is a diverse genus of carnivorous plants that is cosmopolitan in distribution, with Australia its centre of diversity (ca. 160 species in Australia). Collectively known as sundews, their leaves are covered with mobile sticky hairs (“tentacles”) that serve as active flypaper-type traps that catch small invertebrates. This prey is then digested with enzymes and absorbed as nutrition for the plant. Not all invertebrates fall prey to sundews, with sundew bug species of the genus Setocoris China & Carvalho, 1951 (Miridae) avoiding capture and stealing the plant's prey, in an unusual case of kleptobiosis. This specialised interaction suggests that the bug and host plant are highly co-adapted, although most aspects of the natural history of this interaction are poorly understood. In this study, field observations made over the course of 3 months show that the undescribed species Setocoris n.sp_BINA are first present on their host plants (Drosera binata Labill. and Drosera peltata Thunb.) when plants are sticky and catching prey. Sundew bugs are observed first on D. peltata and then D. binata, corresponding to the differing phenologies of each host plant species. These observations generated the following hypotheses for future testing: (1) S. n.sp_BINA move between host species to prioritise prey availability, and (2) S. n.sp_BINA eclosion is triggered by the same moisture and/or temperature cues as their hosts so that hatching coincides with prey availability.

Xiong H. et al.: "First record of silk-loving genus Monteithophila (Hemiptera, Heteroptera, Plokiophilidae) from Asia, with description of a new species from China".

The silk-loving bug Monteithophila hainanensis sp. nov. (Hemiptera, Heteroptera, Plokiophilidae) is described from Hainan, southern China, where it was found on the webs of Spinathele sp. (Araneae, Macrothelidae). This new species represents the first record of the genus Monteithophila Schuh, Štys & Cassis, 2015 outside Oceania. The new species can be distinguished from its congeners by its smaller body size, head uniformly colored yellowish brown to reddish brown, fore major claws slightly longer than mid ones with no significant difference, and distinct morphology of corial glands on the hemelytra. A key to the species of Monteithophila is presented. In addition, the ecological characteristics of the new species and the morphology of the genitalia are briefly discussed.
