Summary: This study describes a new genus, Graziasternum, as well as two new species, Graziasternum graziae sp. nov. and Graziasternum joceliae sp. nov. The discussion includes the phylogenetic position of the new genus relative to other genera, focusing on the importance of thoracic and genital structures. Additionally, the two new species are distinguished and illustrated in the study.

Summary: The study sequenced and analyzed five mitogenomes of the genus Eysarcoris to reconstruct the phylogenetic relationships of tribes within the Pentatominae subfamily. The results revealed differences between species and supported the transfer of E. gibbosus to another genus, Stagonomus. The study laid a foundation for further research on the phylogenetic relationships in Pentatominae.

Summary: The potential distribution of the invasive pest Erthesina fullo under different climate scenarios was studied using the CLIMEX model. The results showed suitable areas for E. fullo in America, Africa, Europe, and Oceania with tropical and subtropical climates under the current climate scenario. However, the suitability decreased in these regions under future climate scenarios while increasing in temperate regions. The study also found a positive correlation between the weekly growth index of E. fullo and photoperiod. These findings provide valuable insights for preventing potential invasion and establishment of E. fullo beyond its current range.

Summary: This study sequenced the complete mitochondrial genomes of three species of Menida to explore the genetic diversity and phylogenetic relationship of the genus Menida and reveal the molecular evolution of the family Pentatomidae, subfamily Pentatominae. The results showed that the characteristics of Menida's mitochondrial genomes were highly conserved within the Menida and had more similar characteristics in Pentatominae. The phylogenetic analysis supported that the genus Menida belongs to the Pentatominae and is closely related to Hoplistoderini.

Summary: In this study, a new fossil species of Nymphalidae, Neptis kabutoiwaensis sp. nov., belonging to the subfamily Limenitidinae, was described and illustrated based on an impression fossil from the Upper Pliocene Motojuku Group in central Japan. This is the first named Papilionoidea fossil discovered from the Pliocene Series. The fossil shares characteristics with the tribe Neptini of Limenitidinae, but the presence of the CuP vein in the forewing distinguishes it from known species of tribe Neptini.

Summary: Thailand, located in Southeast Asia, is a biodiversity hot spot with many endemic species. A recent study on the leafhopper genus Xestocephalus identified 12 new species and recorded 4 species in Thailand for the first time. Detailed morphological descriptions and distributions were provided, contributing to a better understanding of insect fauna in the region.

Summary: The Oriental species belonging to genus Brachycerocoris Costa, 1863 have been revised with description of two new species, B. petrii sp. nov. from India and B. davidii sp. nov. from Philippines. Additionally, female genitalia of B. camelus Costa, 1863 and both male and female genitalia of B. dromedarius (Vollenhoven, 1863) have been diagnosed and illustrated. Host record, bionomics of B. petrii sp. nov. and a key to the Oriental species are also provided.

Summary: This study describes twenty Aptian ammonite species, including one new genus and three new species, from the Todai Formation in central Japan. The ammonite fauna of the Todai Formation is divided into one horizon and two biostratigraphic zones, which are correlated with Upper Aptian standard zonation in various regions. The fauna includes ornate planispiral forms, smooth or weakly ornate planispiral forms, and heteromorph forms, with a nearly even ratio of morphotypes similar to the Aketo Formation in the Miyako Group.

Summary: This study describes a new species of soft scale insect, Luzulaspis kinakikir Tanaka sp. nov., collected from Carex miyabei on Hokkaido Island, Japan, based on adult female morphology. The new species, belonging to the Scotica group of Luzulaspis, can be distinguished from other species by characteristics such as the distribution of multilocular pores, morphology of tubular ducts, and absence of dorsal tubular ducts on the head.

Summary: A new species of aneurine flat bug, Aneurus (Aneurodes) taterasanus sp. nov., is described from western and southwestern Japan, marking the first record of the subgenus in the country. The detailed structure of the phallus of this new species is documented for the first time in the subfamily Aneurinae. The study also provides identification keys for the subgenus Aneurodes and the genera Aneurus and Paraneurus occurring in Japan.

Summary: Snow algae are photosynthetic microbes found in melting snow in alpine and polar regions. Analysis of pigments and species composition in colored snow from Mt. Tateyama in Japan revealed four main types, with Sanguina algae dominant in producing astaxanthin-rich red snow. The study also showed that different algae species, such as Chloromonas or Chlainomonas, can lead to varying pigment compositions in colored snow.

Summary: Transcriptomes of salivary glands were sequenced from five stink bug species collected from non-crop habitats, and 677 putative secreted proteins were identified. These proteins may play roles in suppressing plant defense signaling and deactivating plant defense molecules, as well as participating in the digestion of plant tissues, protection from entomopathogens, and deposition of salivary sheaths.
