Figure 2 (A–H)
Diagnosis. Clypeus without ventral teeth (Fig. 2C); antenna with 23 antennomeres, F1 subequal to F2 and basal half of antenna tricoloured (Fig. 2A); scutellar sulcus with three carinae (Fig. 2D); propodeum without distinct and regular areola (Fig. 2D); dorsal carinae of T1 slightly converging apically; metasoma in lateral view moderately convex (Fig. 2H); body mainly black; veins and parastigma light brown; T1 and T2 white laterally; antenna white medially; legs mostly light brown (Fig. 2A).
Description. Holotype, female, length of body 2.0 mm; length of fore wing 1.9 mm.
Head. Eyes very large, glabrous (Fig. 2C); length of eyes in dorsal view 5.9 × longer than temple; face 1.6 × wider than high in anterior view; clypeus 2.0 × wider than high, without teeth ventrally (Fig. 2C); malar space 2.0 × longer than basal width of mandible (Fig. 2C); occipital carina interrupted medio-dorsally (Fig. 2E); lower tooth of mandible as long as upper tooth; face rather flat but medially convex (Fig. 2C); clypeus, face, frons and vertex with dense transverse or oblique striation; OD: POL: OOL = 10: 19: 16 (Fig. 2E).
Antenna. Antennomeres 23 (antenna damaged when photographed); pedicel short compared with other antennomeres, F1 subequal to F2 (Fig. 2A).
Mesosoma. Mesopleuron smooth and shiny (Fig. 2G); surface of propodeum smooth with strongly developed longitudinal and transverse carinae, without distinct and regular areola (Fig. 2D); length of mesosoma 1.8 × its height in lateral view (Fig. 2G); mesoscutum coarsely rugose near notauli and coarsely punctate laterally; scutellum convex strongly (Fig. 2D); notauli present on less than 1/2 length of mesoscutum; scutellar sulcus wide and with three carinae (Fig. 2D); mesopleuron largely smooth and with complete precoxal sulcus, but sulcus rugose anteriorly (Fig. 2G).
Wings. Fore wing (Fig. 2B): SR1 straight; three submarginal cells present; 1-R1 almost extends to apex of wing, 2-R1 absent; subdiscal cell open (CU1b absent); 1-SR+M present and originating from parastigma; 1-M bent; m-cu slightly antefurcal; 1-R1 1.3 × longer than pterostigma; pterostigma 2.6 × longer than wide; ratio of r: 3-SR: r-m: 2-SR = 10: 16: 18: 35. Hind wing (Fig. 2B): Vein 1-M subequal to Vein M+CU; Vein 1-SC+R of hind wing weakly.
Metasoma. Metasomal carapace with distinct transverse sutures (Fig. 2F); dorsal carinae of T1 slightly converging apically (Fig. 2F); metasoma in lateral view moderately convex and coarsely reticulate-rugose, oval in dorsal view and 2 × longer than wide (Fig. 2H); ratio of maximum length of three basal metasomal tergites 6: 5: 5 (Fig. 2F).
Legs (Fig. 2A). Hind tibia approximately 1.3 × longer than hind tarsus; coxa, femur, tibia and tarsus of hind leg 1.7, 9.4, 5.7, 11.2 × long than wide, respectively.
Colour. Body mainly black, veins and parastigma light brown (Fig. 2A); T1 and T2 white laterally (Fig. 2F); antenna white medially (23 antennomeres, 9–13 white basally; antennae damaged in Fig. 2), remainder of flagellum (except F1) dark brown; three antennomeres basally brownish yellow; legs mostly light brown and light yellow.
Male. Unknown.
Material examined. Holotype (BIIC), female, Gaoligong Mountain Nature Reserve, Yunnan, China, 25°18′22.99″N, 98°47′37.34″E, elevation 1686 m, 15–30.VI.2020, Yi Lang. No. 2020GLG00019; Paratype (ZJUH), female, Emei Mountain, Sichuan, China, 1–2.VIII.2006, Gao Zhilei, No. 200613087.
Biology. Unknown.
Etymology. We wish that Junli’s son “Yekun Zeng” will grow up as strong as the metasomal carapace of this new species.
Note. The paratype is very similar to the holotype and differs by some minor differences in body colour, the flat scutellum (in holotype distinctly convex; Fig. 2G) and the longer notauli (more than 1/2 length of mesoscutum, in holotype less than 1/2 length of mesoscutum).
