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.

Kim W. et al.: "Additions, corrections, and bibliographic issues on the Heteropteran fauna of Korea (Insecta: Hemiptera)".

We address issues of faunistic studies on Korean true bugs (Hemiptera: Heteroptera) and critically review the literature records on recently (2011–2024) reported species. Furthermore, 18 species in 11 families are newly reported from Korea: Cimicomorpha—Anthocoridae: Elatophilus (Elatophilus) nipponensis Hiura, 1966, Temnostethus (Temnostethus) gracilis Horváth, 1907; Miridae: Stethoconus takaii Nakatani & Yasunaga, 2018, Yamatofulvius miyamotoi Yasunaga, 2000; Reduviidae: Oncocephalus heissi Ishikawa, Cai & Tomokuni, 2006, Polytoxus fuscovittatus (Stål, 1860); Tingidae: Physatocheila nigrintegerrima Souma, 2019; Pentatomomorpha—Aradidae: Aradus unicolor Kiritshenko, 1913, Aneurus (Aneurodes) taterasanus Shimamoto & Ishikawa, 2022, Neuroctenus quercicola Nagashima & Shono, 2003, Mezira pygmaea Hsiao, 1964; Cydnidae: Parachilocoris japonicus Lis, 1994; Lygaeidae: Arocatus rufipes Stål, 1872; Pachygronthidae: Pachygrontha similis Uhler, 1896; Pentatomidae: Niphe elongata (Dallas, 1851); Pyrrhocoridae: Dysdercus (Paradysdercus) evanescens Distant, 1902; Rhyparochromidae: Appolonius oblongus Tomokuni, 1995, Neolethaeus lewisi (Distant, 1883), of which five species are recorded based on photographic evidence. Eleven species are excluded from the Korean fauna based on review of literature records: Acanthosomatidae: Elasmucha signoreti Scott, 1874, Lindbergicoris gramineus (Distant, 1883); Aradidae: Brachyrhynchus taiwanicus (Kormilev, 1957), Daulocoris formosanus Kormilev, 1971, Mezira subtilis Josifov & Kerzhner, 1974; Miridae: Apolygus nigrovirens (Kerzhner, 1988), Neolygus lobatus (Linnavuori, 1963), Kasumiphylus ryukyuensis (Yasunaga, 1999), Tytthus parviceps (Reuter, 1890); Pentatomidae: Erthesina fullo (Thunberg, 1783), Plautia splendens Distant, 1900. Three species are reconfirmed from Korea: Geocoridae: Geocoris (Geocoris) proteus Distant, 1883; Rhyparochromidae: Caridops pseudadmistus Zheng, 1981; Veliidae: Halovelia septentrionalis Esaki, 1926.
