The Chiricahua Mountains in southeastern Arizona are renowned for their exceptional biodiversity and high levels of endemism. Morphological, genomic, behavioral, and distributional data were used to report the discovery of a remarkable new tarantula species from this range. Aphonopelmajacobii sp. nov. inhabits high-elevation mixed conifer forests in these mountains, but also co-occurs and shares its breeding period with A.chiricahua-a related member of the Marxi species group-in mid-elevation Madrean evergreen oak and pine-oak woodlands. This marks the first documented case of syntopy between two montane endemics in the Madrean Archipelago and adds to our knowledge of this threatened region's unmatched tarantula diversity in the United States. An emended diagnosis and redescription for A.chiricahua are also provided based on several newly acquired and accurately identified specimens. Phylogenetic analyses of mitochondrial and genomic-scale data reveal that A.jacobii sp. nov. is more closely related to A.marxi, a species primarily distributed on the Colorado Plateau, than to A.chiricahua or the other Madrean Sky Island taxa. These data provide the evolutionary framework for better understanding the region's complex biogeographic history (e.g., biotic assembly of the Chiricahua Mountains) and conservation of these spiders.

Four new species of Liphistius belonging to the birmanicus species group are described from Myanmar based on both sexes: L.kalaw Zhan & Xu, sp. nov. (♂♀), L.kanpetlet Zhan & Xu, sp. nov. (♂♀), L.nawngau Zhan & Xu, sp. nov. (♂♀) and L.rostratus Zhan & Xu, sp. nov. (♂♀). Currently, Myanmar stands as the westernmost country where Liphistius is distributed, with the new species L.kanpetlet sp. nov. being found in the westernmost region of Myanmar.

Based on the examination of specimens housed in several scientific collections, we expand the known tiger beetle fauna of China, and eight species are recorded from China for the first time. The occurrence of Cicindela (Cicindela) sachalinensis raddei Morawitz, 1863 in Shanxi Province, and Neocollyris (Neocollyris) saphyrina (Chaudoir, 1850) in China are re-established. We provide distribution maps and habitus photographs of examined specimens for the newly recorded and revised species. We also discuss potential research hotspots for future taxonomic studies of tiger beetles in China.

The species of Amemboa Esaki, 1925 from China are reviewed. Amemboahainanica sp. nov., is described from Hainan Island, and Amemboaburmensis J. Polhemus & Andersen, 1984 is newly recorded from China. Additionally, diagnoses and new distribution records are provided for six species previously reported from China: A.brevifasciata Miyamoto, 1967, A.cristata J. Polhemus & Andersen, 1984, A.esakii J. Polhemus & Andersen, 1984, A.fumi Esaki, 1925, A.riparia J. Polhemus & Andersen, 1984, and A.speciosa J. Polhemus & Andersen, 1984. Photographs and line drawings of the habitus, the diagnostic characteristics of males, in-situ habitus, and their habitats are presented. A key and a distribution map are also provided for species of Amemboa occurring in China.

Three new species of the genus Belisana Thorell, 1898 are described from karst caves in Guangxi, China: Belisanalangping Zhang, Li & Yao, sp. nov. (♂♀), B.lingui Zhang, Li & Yao, sp. nov. (♂♀), and B.tianyang Zhang, Li & Yao, sp. nov. (♂♀). In addition, a list of all Belisana species from Guangxi is also provided.

With 39 described species in three subgenera, the Gnaptorina is the second most species-rich genus in the subtribe Gnaptorinina (Tenebrionidae: Blaptinae). In this study, a phylogeny of Gnaptorina was reconstructed based on one nuclear (28S-D2) and three mitochondrial (COI, Cytb, and 16S) gene fragments; multiple molecular species delimitation approaches were also implemented to assess the taxonomic status of larval specimens based on COI gene fragment. Larvae of five known species of the subgenus Hesperoptorina are described and illustrated for the first time: Gnaptorinanigera Shi, Ren & Merkl, 2007, Gnaptorinatishkovi Medvedev, 1998, Gnaptorinabrucei Blair, 1923, Gnaptorinahimalaya Shi, Ren & Merkl, 2007, Gnaptorinakangmar Shi, Ren & Merkl, 2007. A key to larvae of four genera of the tribe Blaptini and a key to the known larvae of the genus Gnaptorina are provided. This study provides valuable morphological data for larval studies of the tribe Blaptini.

Species delimitation presents a significant challenge in biology, particularly in systematics. Here, an integrative approach is employed to assess the species boundaries of widely distributed Palearctic Stenodema species. Due to their diversity, wide distribution, and the absence of comprehensive morphological and molecular data for most species, revising Stenodema is both daunting and time-consuming. Our study focuses on detailed examinations of male and female genitalia, coupled with phylogenetic analyses based on two mitochondrial markers (cytochrome c oxidase subunit I and 16S rRNA) and species delimitation analyses. Eight species with wide distributions are reviewed, Stenodematrispinosa Reuter, 1904 is synonymized with S.pilosa (Jakovlev, 1889), and a lectotype for Stenodematuranica Reuter, 1904 is designated. Morphological and molecular data effectively distinguish all species, revealing distinct clades and relationships. Notably, S.calcarata and S.pilosa form a well-supported clade, while S.virens and S.turanica share a lineage with Nearctic species. Stenodemarubrinervis and S.sibirica are morphologically similar and form a distinct clade in all phylogenies. Species delimitation analyses confirm the separation of all studied species, and genetic distances suggest the potential existence of cryptic species within S.calcarata and S.pilosa. This study highlights the advantages of integrative taxonomy in delimiting species with intricate and relatively recent phylogeographic histories.
