Abstract: Atopotrophos chinensis Kasparyan, 1975 (Figs 4, 5) Kasparyan 1975: 1261–1282. Tea Fauna Project 2023 (Holotype female Atopotrophos chinensis Kasparyan, 1975) Material examined. Holotype, CHINA • 1 ♀; Sichuan, Garzê Tibetan Autonomous Prefecture, Danba County, Approximate coordinates: 30°46’19.66”N 101°42’33.84”E, 2450m, broadleaved forest, 19 Jul. 1893, Grigory Potanin leg. (ZIN). “[White label] СЫ-ч., р. ПасЫн- // коу вЫШe Чжумсe // Потан. 19.VII.93. // [red label] Holotypus // Atopotrophos // chinensis // Kasparyan ”. (Fig. 4). Description. Holotype, female. MEASUREMENTS. Body length 5 mm, fore wing length 4 mm. BODY. Matt and clothed with setae (Fig. 4). HEAD. Antenna 1.3 × length of fore wing, with 30 flagellomeres without white subapical band (Fig. 4). Scape 1.5 × as long as broad (Fig. 5A). First flagellomere 1.3 × longer than second and 1.4 × longer than third. Head roundly narrowed behind eyes, its width 1.55 × its length (Fig. 5B). Inner margins of eyes slightly converging ventrally (Fig. 5A). Lateral ocellus separated from eye margin by 2.5 × its widest diameter. Frons shagreened, not punctate. Antennal sockets lifted slightly above frons in profile (Fig. 4). Anterior tentorial pit distinct and deep (Fig. 5A). Clypeus 0.5 × as high as wide, separated from face by distinct impression, distinctly densely clothed with setae (Fig. 5A), in profile flat (Fig. 4). Its margin sharp, medially concave, laterally produced as small lobes, medially with a dense apical fringe of short, parallel, ventrally directed setae (Fig. 5A). Mandible strongly widened apically, crescent-shaped, its dorsal tooth hidden when the mandible is closed (Fig. 5A), its ventral tooth twisted anteriorly, distinctly longer than dorsal tooth (Fig. 5A). Malar space almost as long as basal mandible width (Fig. 5A). MESOSOMA. Pronotum elongate, dimly shining, with slight transverse striation (Fig. 4). Epomia distinct (Fig. 4). Mesopleuron dimly shining, sparsely setose, with dense rough punctures, shagreened, and striated in its lower part (Fig. 4). Mesoscutum weakly shining, sparsely setose, impunctate, with lateral carina (Fig. 4). Notauli strong. Scutellum not forming an apical tooth. Propodeum impunctate, with carinae complete (Fig. 5C). Lateral longitudinal and posterior transverse carina not forming any tooth (Fig. 4). Area basalis distinctly defined, pentagonal, area superomedia 1.8 × its width (Fig. 5C). Spiracle of propodeum closer to pleural longitudinal carinae, joined to the later by a transverse carina (Figs 4, 5C). Length of hind femur 7.3 × its width centrally (Fig. 4). Spurs of hind tibia almost equal. Fore wing vein 3rs-m absent, vein 2m-cu with two bullae, abscissa of CU longer than 2cu-a. Hind wing with distal abscissa of Rs, M, CU and AA absent, cu-a shorter than CU. METASOMA. Smooth, impunctate. T1 length 4.3 × its posterior width (Fig. 5D). Glymma absent, spiracle at 0.5 (Fig. 4). S1 fused with T1. Ovipositor weakly upcurved, 1.1 × as long as apical height of metasoma, or 0.6 of T1 (Fig. 4). Ovipositor sheath upcurved. COLORATION. Black, except the following which are marked with reddish-brown: antenna, face and metasoma; the following are marked with yellowish-red: basal flagellomeres, clypeus, mesosoma, legs except red hind coxa and femur; mandibles yellow except apically, palpi and tegula. Male. Unknown. Hosts. Unknown. Distribution. Sichuan (China). Diagnosis. Atopotrophos chinensis can be distinguished from all other Atopotrophos spp. by the combination of: head roundly narrowed behind eyes (its width 1.55 × its length), face rather setose and matt, clypeal margin medially concave, malar space almost as long as basal mandible width, antenna entirely dark without white subapical flagellomeres.
