Malipatil M.B. & Liu Y.: "Additions to the knowledge of Stylogeocoris and Umbrageocoris of Australia (Hemiptera: Heteroptera: Geocoridae)".

The recent discovery of the type specimen of Geocoris provisus Bergroth, 1895 (Hemiptera: Heteroptera: Geocoridae) has necessitated the following new subjective synonymy: Stylogeocoris provisus (Bergroth, 1895), comb. nov. = Stylogeocoris elongatus (Distant, 1901), syn. nov. Umbrageocoris malipatili Kóbor, 2022 is redescribed and illustrated, comparative notes are provided for Umbrageocoris Kóbor, 2019 and Geocoris Fallén, 1814 as well as for some species of these two genera from Australia. Stylogeocoris bicoloratus Malipatil, sp. nov. is described, and an updated key to the species of genus Stylogeocoris Montandon, 1913 is presented.

Namyatova A.A., Dzhelali P.A. & Bolshakova D.S.: "Integrative delimitation of Apolygus (Insecta: Heteroptera: Miridae: Mirinae) species known from Russia with the emphasis on Apolygus lucorum and Apolygus spinolae having trans-Palearctic distribution".

Apolygus (Insecta: Heteroptera: Miridae: Mirinae) is a large and taxonomically challenging trans-Palearctic genus comprising 74 species, and it has never been revised. The greatest diversity of this genus occurs in Asia, and 15 species have been recorded from Russia. Among them, Apolygus limbatus, Apolygus lucorum, and Apolygus spinolae are trans-Palearctic, and A. lucorum and A. spinolae are economically important as pests. Previous studies have shown that A. lucorum and A. spinolae are very similar in morphology and that the barcoding region might not be suitable for their identification. In this study a revision of the Apolygus representatives inhabiting Russia is provided based on morphological and molecular data. Mitochondrial (COI and 16S rRNA) and nuclear markers (ITS1 and 28S3 rRNA) were used for phylogenetic analyses and automatic species delimitation methods were applied. Apolygus lucorum, A. malaisei, A. nigronasutus, A. nigrovirens were treated as junior synonyms of A. spinolae because morphological and molecular data did not show differences between those species. Apolygus shikotan sp. nov. was described as new to science. Morphological data and the COI phylogeny show that A. limbatus might represent two separate species. However, additional specimens and nuclear markers for both groups are needed to test this hypothesis. The synonymy of A. syringae with A. hilaris was supported based on the morphological data. Apolygus gotorum and A. subhilaris are reported from Russia for the first time. The nuclear marker ITS1 is the most reliable marker for species delimitation and identification of Apolygus species.

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.
