Zele Curtis is a braconid parasitoid wasp genus within the subfamily Euphorinae (Hymenoptera, Braconidae), consisting of only 30 species worldwide. The Chinese species of the genus Zele are revised and 29 species are now recognised, including 19 species new to science: Z. aquilus Fang, van Achterberg & Chen, sp. nov., Z. carinatus Fang, van Achterberg & Chen, sp. nov., Z. confusus Fang, van Achterberg & Chen, sp. nov., Z. cristatus Fang, van Achterberg & Chen, sp. nov., Z. curvatus Fang, van Achterberg & Chen, sp. nov., Z. curvinervis Fang, van Achterberg & Chen, sp. nov., Z. densipunctatus Fang, van Achterberg & Chen, sp. nov., Z. extensus Fang, van Achterberg & Chen, sp. nov., Z. fulgidus Fang, van Achterberg & Chen, sp. nov., Z. fuscatus Fang, van Achterberg & Chen, sp. nov., Z. impolitus Fang, van Achterberg & Chen, sp. nov., Z. inclinator Fang, van Achterberg & Chen, sp. nov., Z. irregularis Fang, van Achterberg & Chen, sp. nov., Z. petiolatus Fang, van Achterberg & Chen, sp. nov., Z. rugulosus Fang, van Achterberg & Chen, sp. nov., Z. sculpticoxis Fang, van Achterberg & Chen, sp. nov., Z. shaanxiensis Fang, van Achterberg & Chen, sp. nov., Z. syntomus Fang, van Achterberg & Chen, sp. nov., and Z. vacatus Fang, van Achterberg & Chen, sp. nov. 31 barcode region sequences of mitochondrial cytochrome c oxidase I (COI) from the genus Zele were obtained and combined with 102 sequences from BOLD. They were used to validate new species and to get an indication of similarity among species. Three species are reinstated: Zele peronatus (Shestakov, 1940), Z. romani (Fahringer, 1929), and Z. rufulus (Thomson, 1895). In addition, an identification key for the Zele species recorded in China (plus one expected species) is provided.

The tribe Alysiini Leach is a diverse group comprising 78 genera and approximately 1,600 valid species worldwide. In China, 27 genera and over 140 species have been recorded to date. The genera Dapsilarthra Förster, Grammospila Förster and Heterolexis Förster are small groups within the tribe Alysiini, each containing only seven or eight valid species worldwide. These genera have been rarely studied in China, with Heterolexis represented by only one previously recorded species and Dapsilarthra and Grammospila each by three species. This study reviews Dapsilarthra , Grammospila and Heterolexis . Four new species are described from China: Grammospila angustisulcata sp. nov., Dapsilarthra spiraculata sp. nov., D. parallela sp. nov. and D. aurantia sp. nov. Three species of Heterolexis are newly recorded from China. Keys to species of these genera are provided. The morphological variation of the Chinese specimens is described and illustrated.

The genus Aerophilus Szépligeti, 1902 (Hymenoptera, Braconidae, Agathidinae) is distributed throughout the globe, attacking caterpillars from multiple families within the Lepidoptera. Two species of Aerophilus were recorded from China prior to this study. Four Chinese species of Aerophilus Szépligeti, 1902 are recognised. Two new species, A. brevicaudis sp. nov. and A. convexus sp. nov., are described and illustrated. A species, A. rufipes (Nees, 1812), is recorded from China for the first time. A new synonym is proposed, A. ebulus (Nixon, 1950) with A. romani (Shestakov, 1940). A key to Chinese species of the genus Aerophilus is provided.

A new species of the genus Marshiella Shaw, 1985 is described and illustrated from Xinjiang (NW. China): Marshiella baichengensis Amat & van Achterberg, sp. nov. In addition, a key to the ten known species and one new species in this genus is provided.

The genus Phanerotomella Szépligeti, 1900 (Hymenoptera, Braconidae, Cheloninae, Phanerotomini), is restricted to the Old World, with no records from the Nearctic or Neotropical Regions. Reliably species-identified COI sequences are scarce for this genus in public databases, hindering comprehensive phylogenetic and DNA-barcoding analyses. This study provides 29 COI sequences for this genus. Two species delimitation approaches, combined with morphological evidence, were employed to delimit species. The findings indicated the existence of 16 species, including one new species: P. nitidifascia Fang, He, van Achterberg, sp. nov. and one newly-recorded species: P. namkyensis Sigwalt, 1978. Additionally, we provide the first available COI sequence for the Chinese endemic genus Siniphanerotomella.

The genus Phanerotoma Wesmael, 1838 (Hymenoptera, Braconidae, Cheloninae, Phane- rotomini) is distributed across all six major zoogeographical regions, with the highest species diversity recorded in the Palaearctic Region. DNA barcoding provides a robust method for species identification, yet its effectiveness for the genus Phanerotoma is limited by the scarcity of reliable, species-level data from specific regions in public databases. This gap makes it essential to contribute comprehensive genetic resources to advance taxonomic research. This study presents a comprehensive COI dataset of 92 sequences for the genus Phanerotoma, employing both the Automatic Barcode Gap Discovery (ABGD) method for species delimitation and the bPTP model for phylogenetic inference. The integrated analytical approach revealed 18 distinct species, including five new species; all species new to science are described and illustrated, and updates of the most recent key to the Chinese species are included.
