562F975760E05B2DB9B59669F67A9659.taxon	description	Description. Head. Antennae with 12 segments; antennal scape slightly curved; scape reaching two-thirds of the length of the head. Head in full-face view subrectangular, slightly longer than broad, lateral margins convex, posterior margin slightly concave in middle, with posterolateral corner rounded, frontal carina short, only reaching to the middle of head. Anterior clypeus nearly straight, antennal scrobe obvious (Fig. 1 A); in lateral view, the diameter of the eye less than half of the maximum diameter of the enlarged part of the antennal terminal segment (Fig. 1 D). Mesosoma. In dorsal view, lateral margins slightly convex, anterior margin convex (Fig. 1 C); in lateral view, dorsal outline strongly convex, with transverse curve; promesonotal suture and metanotal groove inconspicuous; mesopleuron demarcated from pronotum by a distinct suture, but not demarcated from mesonotum and metapleuron; propodeal spines short triangular (Fig. 1 D). Metasoma. In dorsal view, petiole circular, as long as broad; lateral margins slightly convex; anterior margin convex and posterior margin slightly concave (Fig. 1 C); in lateral view, petiolar node slightly convex dorsal outline, slightly higher than long, with bilateral edge sloped slightly (Fig. 1 D). Postpetiole in dorsal view clearly larger than petiole, oval, lateral margins apparently convex, as long as broad (Fig. 1 C); in lateral view, slightly convex dorsal outline (Fig. 1 D). In dorsal view, anterior margin of gaster obviously concave (Fig. 1 C). Sculpture. Mandibles and clypeus longitudinally striate; antennal scape finely puncta; frontal area longitudinal striate, lateral and posterior part of head slightly reticulate (Fig. 1 A). The pronotum reticulate, the mesonotum and metanotum longitudinally striate (Fig. 1 C); the lateral sides of the mesosoma with transverse curve and sparsely puncta (Fig. 1 D). Dorsum of petiole sparsely rugose (Fig. 1 C). Coxa, peduncle, subpetiolar process with dense puncta (Fig. 1 D). Gaster smooth and shining (Fig. 1 C). Pilosity. Body entirely covered with abundant decumbent, sub-erect, and erect hairs (Fig. 1 A, C, D). Coloration. Body brown. Antennae and legs slightly yellowish-brown (Fig. 1).	en	Zhang, Benan, Du, Congcong, Chen, Zhilin (2025): Tetramorium sinensis sp. nov., a parabiotic ant from China, with a key to the Tetramorium inglebyi group (Hymenoptera, Formicidae).
