The mature larva of the western Palaearctic ichneumonid Heinrichiella obscura (Gravenhorst) is described for the first time and the morphology is placed in the context of the genus being a basal lineage of the Ophioninae. The described larvae of Ophioninae are reviewed and a new larval diagnosis of the family is provided.

Larnaca qianlei sp. nov. is described from Xizang Autonomous Region, China. The new species is characterized by the long, downcurved spiniform processes on the male ninth abdominal tergite and the straight posterior margin of the female seventh abdominal sternite. Larnaca (Larnaca) squamiptera Ingrisch, 2018 becomes a new synonym of Larnaca (Larnaca) infolda Du, Bian & Shi, 2017. Female morphology of Larnaca (Larnaca) walle Yin & Meng, 2021 is described and illustrated for the first time. Types of the new species in this paper are deposited in Museum of Biology, East China Normal University (ECNU), China.

A new species of genus Dacus Fabricius, Dacus (Neodacus) kapoori Maneesh & Hancock sp. nov., is described and illustrated from Himachal Pradesh, India, along with an unnamed Dacus (Neodacus) sp. A key to Asian species of subgenus Neodacus Perkins is provided.

A new species of the flower chafer genus Gametis Burmeister, 1842, Gametis polita Seshima & Yoshida, sp. nov., is described from Tarama-jima Island and Minna-jima Island in the Miyako Islands, southwestern Japan, which was formerly misidentified as Gametis forticula (Janson, 1881). This is the first new species of the subfamily Cetoniinae sensu stricto described from Japan in approximately half a century. Using molecular and morphological evidence, we conclude that the genus Gametis comprises three species in Japan: G. forticula (Janson, 1881), G. polita sp. nov., and G. ishigakiana (Nomura, 1959), which was formerly treated as a subspecies of G. forticula. In addition, G. forticula miyakoana (Nomura, 1959) and G. forticula yonakuniana (Nomura, 1959) are transferred to subspecific status under G. ishigakiana.

We report the rediscovery of the keelback snake Rhabdophis angeli (Bourret, 1934) from its type locality in Tam Dao National Park, Phu Tho Province, Vietnam, nearly 90 years after its original description. Based on an integrative approach combining morphological examination and molecular phylogenetic analyses, we revise the diagnosis of Rhabdophis angeli and formally synonymise Rhabdophis guangdongensis Zhu, Wang, Takeuchi & Zhao, 2014, with R. angeli. Given the current distributional data, made of widely scattered localities, and the presence of potential threats, we recommend that Rhabdophis angeli be categorised as Near Threatened (NT) under the IUCN Red List criteria. This study highlights the importance of comprehensive taxon sampling, particularly in adjacent regions, to improve our understanding of species boundaries and conservation status. An updated identification key is provided for species within the Rhabdophis nuchalis group, highlighting the need for further integrative taxonomic work in this complex.

The Afrotropical genus Afrotelphusa Bidzilya & Mey, 2011 is revised. Four species are recognized as valid, of which three are described here as new: A. butarensis sp. nov. (Rwanda), A. furcatella sp. nov. (Kenya, Ethiopia) and A. inopinata sp. nov. (South Africa). An identification key to all species of the genus is provided. Wing pattern and genitalia of all species are illustrated in detail.

Taxonomic, diagnostic and faunistic data for three species of Nipponophloeostiba Watanabe, 1962 and two species of Phloeostiba Thomson, 1858 are provided. A new combination is proposed: N. temporalis (Cameron, 1930) comb. nov. (from Phloeostiba). A lectotype is designated for Phloeonomus (Phloeostiba) pinicola Champion, 1920. Three new synonyms are established: N. temporalis = Phloeostiba basui Biswas, 2003 syn. nov., = N. hammondi Shavrin, 2024 syn. nov.; Phloeostiba plana (Paykull, 1792) = Phloeostiba pinicola syn. nov. Phloeostiba plana is redescribed and illustrated; the morphological variability of this species, and several taxa related to Phloeostiba are briefly discussed. The spermatheca of Ph. plana is illustrated for the first time. The aedeagus of Phloeostiba lapponica (Zetterstedt, 1838) is illustrated. Several species are recorded from a certain area for the first time: N. hornabrooki Shavrin, 2024 from Solomon Islands, N. longilobata Shavrin, 2020 from Papua New Guinea, Phloeostiba lapponica from Tuva, Taimyr and Chukotka autonomous regions, and Amur Area (Russia), and Ph. plana from Amur Area (Russia) and Vietnam.

The erection of a new genus to accommodate Alella igillimpethu Erasmus, Hadfield, Wepener & Smit, 2023 as Simplalella igillimpethu gen. nov. et comb. nov. is proposed, based on molecular and morphological analyses. The new genus is closely related in the phylogenetic tree to Clavellotis dilatata (Kryer, 1863) but according to genetic divergence, it is more closely related to Parabrachiella merlucci (Bassett-Smith, 1896), Praeclavella nasalis Castro Romero, Montes & Martorelli, 2022, and Praeclavella caudata (Castro Romero & Baeza- Kuroki, 1985) (19%). A. macrotrachelus (Brian, 1906) and A. canthari (Heller, 1865) are closely related, with 16% genetic divergence between them. Despite their confirmed validity, the cryptic species within the genus show no discernible morphological differences. A revision of the other species currently included in Alella Leigh-Sharpe, 1925, based on molecular data, is recommended to clarify their true taxonomic position. The molecular analysis also reveals a novel placement of Clavellisa Wilson C.B., 1915, which appears basal to all other analyzed Lernaeopodidae, whereas in previous phylogenies of Lernaeopodidae it was placed at the base of the Clavella Oken, 1815 branch. This new position could be explained by the presence of a short uropod in Clavellisa, along with vestigial thoracic legs in some speciesfeatures that suggest a primitive condition.

A new species of the genus Necydalis Linn, 1758 (Coleoptera: Cerambycidae: Lepturinae) is described and illustrated from Mt. Dahanshan in southern Taiwan. This represents the first discovery of a new Taiwanese species of this genus in nearly half a century. Based on morphological analysis, the new species and seven related species are provisionally placed in the Necydalis ulmi group, whose morphological characteristics and biogeographical context are discussed. These findings enhance our understanding of the diversity and distribution of Necydalis in East Asia.

We document 59 Naticidae species from the Early, Middle and Late Miocene of the Eurasian Paratethys Sea. These species are placed in 13 genera, of which Figovina nov. gen., Pseudolinices nov. gen., Robbanacca nov. gen. and Tethynices nov. gen. are introduced as new genera. The Naticinae genus Cochlis and the Polinicinae Euspira experienced considerable radiations. Naticid species richness in the Central Paratethys was highest during the Middle Miocene Climatic Optimum of the Langhian, reaching 35 species. This diversity is comparable to that of modern tropical eastern Atlantic naticids along West Africa. The subsequent cooling of the Miocene Climate Transition caused a decline of species numbers to 15 species, comparable to that of the modern Mediterranean Sea. The Miocene Eastern Paratethys harbored a much lower diversity without autochthonous radiations. Cochlis cuniculata nov. sp., Cochlis degregorioi nov. sp., Cochlis gebhardti nov. sp., Cochlis micromillepunctata nov. sp., Cochlis neoobscura nov. sp., Cochlis paragigantica nov. sp., Cochlis pseudoprotracta nov. sp., Cochlis zachosi nov. sp., Naticarius lucapedrialii nov. sp., Euspira amitrovi nov. sp., Euspira incus nov. sp., Euspira merlei nov. sp., Euspira moravica nov. sp., Euspira vinitor nov. sp., Euspira vohlandae nov. sp., Euspira wagramensis nov. sp., Figovina yasenivensis nov. sp., Payraudeautia profunda nov. sp., Sigaretotrema vindobonense nov. sp., and Sinum magnificum nov. sp. are described as new species. Tectonatica scutaria nov. nom. and Eunaticina martingrossi nov. nom. are introduced as new names for Natica transgrediens elata Schaffer, 1912 [non Bucquoy, Dautzenberg & Dollfus, 1883] and Natica hoernesi Hilber, 1879 [non Fischer & Tournour, 1873], respectively. The unexpectedly high number of new species can be explained by the tendency of earlier authors to lump morphologically similar forms and to uncritically identify them as Natica millepunctata and Euspira helicina, especially as these species did not even occur in the Paratethys Sea. Our analysis clearly documents the importance of revisions of larger taxonomic units for estimating past biodiversity.
