Kment P., & Lis J.A.: "Dismegistus madagascariensis sp. nov., the first representative of the family Parastrachiidae (Hemiptera, Heteroptera) in Madagascar"

The species Dismegistus madagascariensis sp. nov. is described from Andohahela National Park, southeastern Madagascar. It represents the first record of the genus Dismegistus Amyot & Serville, 1843, and the family Parastrachiidae (Hemiptera, Heteroptera, Pentatomomorpha, Pentatomoidea) from the island. The new species is compared with the six previously described congeners, and a checklist with their distributions is provided.

Taszakowski A., Kim J. & Jindra Z.: "Further records of the tribe Gigantometopini (Hemiptera, Heteroptera, Miridae, Isometopinae) with descriptions of three new genera and five new species."

Gigantometopini Herczek, 1993 is a small tribe of jumping tree bugs (Hemiptera, Heteroptera, Miridae, Isometopinae). Of the 16 extant species classified in Gigantometopini, 13 have been described in this century. In this paper, we described three new genera, Malaymetopidea gen. nov., Utarametopus gen. nov., and Wallacemetopus gen. nov. Five new species are described: Malaymetopidea maculata sp. nov. from Malaysia (Malay Peninsula), Planicapitus brunneus sp. nov. from South Thailand (Malay Peninsula), and Utarametopus linuspitti sp. nov., Utarametopus striatus sp. nov., and Wallacemetopus anteriotenebrosus sp. nov. from Indonesia (North Sulawesi). Habitus images and scanning electron micrographs of the selected structures of the new taxa are provided. New localities for Planicapitus luteus Taszakowski, Kim & Herczek, 2020, and Sulawesimetopus henryi Herczek, Gorczyca & Taszakowski, 2018 are recorded. Male genitalia of Malaymetopidea maculata sp. nov., Planicapitus brunneus sp. nov., and Wallacemetopus anteriotenebrosus sp. nov., and a distributional map of all Gigantometopini species are presented.

Simoncini A. et al.: "Range Expansion of the Giant Water Bug Lethocerus patruelis (Stål, 1854) in Europe"

Climate change is altering freshwater ecosystems, causing extinctions, range expansions, and facilitating biological invasions. Colonization by novel species can drastically affect local biodiversity, particularly in aquatic habitats. Lethocerus patruelis (Stål, 1854) is a large predatory aquatic insect whose distribution spans from the Balkans to south-eastern Asia. In the last decades, L. patruelis sightings outside its known range have increased, particularly in Italy. The aim of this study was to assess the drivers of this expansion and the potential for future spread. We collected records of L. patruelis using published literature, citizen-science platforms, and social media. These data were used to test for directional expansion and to compare historical and novel niches. Second, we used observations from the historical range of the species to create a suitability model using MaxEnt, testing it using observations from Italy. Finally, we projected the model under three future climatic scenarios to assess the potential for future expansions. We detected a significant westward and southward expansion of L. patruelis in Italy. Niche conservatism between historical and novel ranges was observed. Nonetheless, we found limited overlap and a high level of niche unfilling, suggesting an ongoing colonization process. The suitability model showed good predictive performance, indicating a preference toward Mediterranean climates and a selection against agricultural areas. Suitable areas were predicted to increase under all three future climatic scenarios. This study suggests an ongoing spread of L. patruelis and a strong expansion potential in Europe facilitated by climate change.
