Second tergite strongly mat, punctate posteriorly, 2.5 × longer than wide at apex, 1.4 × longer than third segment. Third tergite ca. 1.4 × longer than its apical width. Ovipositor ca. 2.0 × longer than apical depth of metasoma, without a subapical notch. Colour. Head generally pale yellow except ocellar region black and vertex medially light brownish. Scape and pedicel yellowish-brown; 1 st to 10 th flagellomeres basally gradually brownish, 10 th to 15 th flagellomeres white, the rest of antenna blackish-brown. Mandible except teeth yellow, teeth blackish-brown. Tegula yellow. Mesoscutum light brown with pale yellow stripe following notaulus. Scuto-scutellar groove black. Propodeum basal-laterally light brownish. Legs yellowish-brown except coxa whitish. Second tergite with a blackish-brown spot laterally and third tergite with a light brown spot laterally.	en	Han, Yuan-Yuan, Chen, Meng-Meng, Dong, Yan (2024): A new species of Lusius Tosquinet (Hymenoptera, Ichneumonidae, Ichneumoninae) from China, with a key to Chinese species.

994887876B03A761B3E9FBC179F4FF22.taxon	discussion	Remarks. The genus Lusius show great variation in clypeus: (1) truncated in L. macilentus and L. mayfoi (Tosquinet 1903; Saunders & Ward 2017); (2) broadly rounded in L. tenuissimus (Heinrich 1938; Rousse et al. 2013; Dal Pos et al. 2023); (3) strongly pointed apico-laterally in L. flummox and L. castanoi (Rousse et al. 2013; Dal Pos et al. 2023; Nascimento et al. 2024); (4) round medially in L. hunanensis (this study). Kusigemati (1986) and Graf (2000) used “ emarginated ” or “ not emarginated ”, “ thin ” or “ thick ” to describe clypeus, which indicated more variation may present in this genus. And our new species, L. hunanensis, is unusual among species of the genus in that its clypeus is rounded medially.	en	Han, Yuan-Yuan, Chen, Meng-Meng, Dong, Yan (2024): A new species of Lusius Tosquinet (Hymenoptera, Ichneumonidae, Ichneumoninae) from China, with a key to Chinese species.
