description: Wroughtonia plana, sp. nov.   Figures 71–81  
TYPE MATERIAL: Holotype, ♀, “Hel.003” (IEBR), NW Vietnam: Son La, Thuan Chau, Copia NR, 1200 m, 5.vi.2008, L.X. Hue.  
DISTRIBUTION: NW Vietnam: Son La (Thuan Chau).  
BIOLOGY: Unknown.  
 DIAGNOSIS: Antenna with 31 segments; antennal segments 3–19 pale yellow; maxillary palp 1.75 × as long as head; in frontal view width of face 1.8 × length of face and clypeus combined; frontal protuberance robust, higher than lateral frontal carina; in dorsal view width of head 1.5 × its median length; height of eye 1.9 × temple; in lateral view height of eye 1.3 × its transverse width; transverse width of eye 1.7 × temple; face coarsely rugose; frons, vertex, and temple mat. Mesosoma 2.3 × as long as high; notauli narrow, sparsely crenulate, fused posteriorly with median carina in rather flat posterior area of mesoscutum; scutellar sulcus 0.5 × as long as scutellum; propodeum with basal carina and areola; propodeal areola mat; propodeum transversely rugose laterally. Length of forewing 3.3 × its maximum width; vein 3-SR 1.45 × as long as vein r; vein 2-M 2.1 × 3-SR; hind wing vein 1-M 0.7 × vein 1r-m; vein 2-SC+R transverse, 0.2 × vein 1r-m. Foretarsus 1.65 × as long as foretibia; hind femur with ventral serrations and acute tooth-shaped protuberance; hind femur (without tooth or serrations) 3.8 × as long as its maximum width and rugose-punctate. First metasomal tergite 1.8 × its apical width; dorsal carinae in basal 0.6 of tergite; first tergite largely smooth, except sparsely punctate-reticulate medioapical area; median length of second tergite 0.9 × its apical width, and 1.25 × third tergite; second and third tergites smooth.   
 NOTES: W. plana, sp. nov., runs to W. eurygenys Yan and Chen, 2017, from China in the key by Yan et al. (2017), but differs as follows: (1) in dorsal view length of eye 1.9 × as long as temple (1.2 × in W. eurygenys); (2) first metasomal tergite 1.8 × as long as its apical width (1.4 × in W. eurygenys); and (3) hind coxa and femur yellow and only infuscate apically (reddish brown in W. eurygenys).

 Wings. Forewing: length of forewing 3.3 × its maximum width (118:36); pterostigma 3.8 × as long as wide (50:13); vein 3-SR 1.45 × as long as vein r; r:2-SR:3-SR:SR1:r-m = 11:20:16:90; 1-CU1:cu-a:2-CU1 = 4:14:27; second submarginal cell trapezium shaped, vein 2-M 2.1 × 3-SR (33:16) (fig. 77); hind wing: vein 1-M 0.7 × 1r-m (17:23); vein 2-SC+R transverse, 0.2 × vein 1r-m (5:23); hind wing with 4 hamuli.   
 Legs: Foretarsus 1.65 × longer than foretibia (43:26); hind femur with ventral serrations and acute tooth-shaped protuberance (fig. 79); length of hind femur (without tooth or serrations) 3.8 × as long as its maximum width and rugose-punctate; hind coxa sparsely finely punctate laterally; hind tibia slightly curved basally (fig. 80); hind femur, tibia, and basitarsus 3.8 (79:21), 9.2 (110:12), and 6.3 × (38:6) as long as their width, respectively; hind basitarsus 0.35 × as long as hind tibia (38:110) and 0.7 × as long as hind tarsal segments 2–5 (38:52); fourth hind tarsal segment 0.3 × as long as telotarsus (5:17).

 Male: Unknown.   
 ETYMOLOGY: From planus (Latin for “even, flat”), because of the flat mesopleuron.
