description: Wroughtonia laevis, sp. nov.   Figures 59–70  
TYPE MATERIAL: Holotype, ♀, “Hel.002” (IEBR), NW Vietnam: Phu Tho, Xuan Son NP, xom Lap, 9.v.2005, PT Nhi.  
DISTRIBUTION: NW Vietnam: Phu Tho (Xuan Son NP).  
BIOLOGY: Unknown.  
 DIAGNOSIS: Antenna with 42 segments; 14th–22nd antennal segments cream white; frontal protuberance lamelliform, blunt apically; maxillary palp long, 1.7 × height of head; malar space 0.4 × height of eye; in dorsal view width of head 1.35 × its median length; height of eye 1.2 × temple; in lateral view height of eye 1.75 × its transverse width; transverse width of eye 0.95 × temple. Mesosoma 2.3 × longer than high; notauli narrow, crenulated anteriorly, rugose posteriorly, divided by median posterior carina; scutellar sulcus 0.4 × scutellum; propodeum with basal carina and areola; propodeum rugose-punctate. Length of forewing 3.5 × its maximum width; vein 3-SR 1.45 × vein r; vein 2-M 1.9 × 3-SR; hind wing vein 1-M 0.6 × vein 1r-m; hind wing with 4 hamuli. Foretarsus 1.4 × longer than foretibia; hind femur only with serrations; hind coxa sparsely punctate; hind femur largely rugose-punctate; length of hind femur (without serrations) 4.35× its maximum width. First metasomal tergite 2.0 × longer than its apical width; dorsal carinae in basal 0.75 of tergite; first tergite smooth basally and apically; mediolateral and median area between dorsal carinae of first tergite sparsely foveolate-punctate; median length of second tergite 0.8 × its basal width; second tergite 1.2 × third tergite; second and third tergites shiny and smooth.   
 NOTES: W. laevis, sp. nov., is similar to W. eurygenys Yan and Chen, 2017, from China according to the key by Yan et al. (2017), but differs as follows: (1) first metasomal tergite 2 × as long as its apical width (1.4 × in W. eurygenys); (2) scapus densely setose ventrally (scapus with few medium-sized setae in W. eurygenys); (3) ovipositor sheath 1.5 × longer than forewing (as long as forewing in W. eurygenys) and (4) antennal segments 14–22 cream white (13th–18th in W. eurygenys).   
DESCRIPTION: Holotype, ♀, body length 8.4 mm, forewing length 8.0 mm, ovipositor sheath 12.0 mm (fig. 59).  
 Head: Antenna with 42 segments; third antennal segment nearly as long as fourth (19:17); in frontal view height of eye 2.0 × its transverse width (34:17); width of face 1.5 × length of face and clypeus combined (40:27); clypeus narrow; malar space as long as mandible width (15:15) and 0.4 × height of eye (15:34) (fig. 61); maxillary palp long, 1.7 × height of head (106:61); in dorsal view width of head 1.35 × its median length (72:53); height of eye 1.2 × temple (26:22); ocelli in rather low triangle, POL:OD:OOL =7:5:16 (fig. 60); distance between front and hind ocelli 0.2 × OOL (3:16) ( fig. 60); frontal protuberance lamelliform, blunt apically (fig. 65); in lateral view height of eye 1.75 × its transverse width (35:20); transverse width of eye 0.95 × temple (20:21) (fig. 62); face coarsely rugose; frons rugose-coriaceous anteriorly and smooth posteriorly; vertex and temple smooth.   
 Mesosoma: Mesosoma 2.3 × longer than high (82:36); pronotal side crenulated anteriorly, finely punctate dorsally, coarsely rugose ventrally and posteriorly; mesopleuron almost flat, smooth; metapleuron areolate-rugulose (fig. 64); lobes of mesoscutum almost smooth, with scattered fine punctures; notauli narrow, crenulated anteriorly, rugose posteriorly, divided by median posterior carina (fig. 63); scutellar sulcus narrow, with one carinae, 0.4 × scutellum (8:22); scutellum almost smooth; propodeum with basal carina and long areola (fig. 67); propodeum rugose-punctate.   
 Wings: Forewing: length of forewing 3.5 × its maximum width (98:28); pterostigma 4.0 × as long as wide (48:12); vein 3-SR 1.45 × vein r; r:2-SR:3-SR:SR1:r-m = 11:18:16:87:13; 1-CU1:cu-a:2-CU1 = 3:16:30; 1-M:r-m = 31:14 (fig. 69); vein 2-M 1.9 × 3-SR (31:16). Hind wing: vein 1-M 0.6 × vein 1r-m (14:24) (fig. 70); hind wing with 4 hamuli.   
 Legs: Foretarsus 1.4 × longer than foretibia (58:42); hind femur only with serrations (fig. 67); hind coxa sparsely punctate; hind femur largely rugose-punctate (fig. 66); length of hind femur (without serrations), tibia, and basitarsus 4.35 (74:17), 10.6 (106:10), and 9.25 × (37:4) as long as their maximum width, respectively; hind basitarsus 0.3 × hind tibia (37:106), and 0.7 × hind tarsal segments 2–5 (37:56); fourth hind tarsal segment 0.4 × as long as telotarsus (6:14).   
 Metasoma: Metasoma 0.7 × as long as head and mesosoma combined (35:49); first tergite 2.0 × longer than its apical width (55:27) (fig. 68); dorsal carinae in basal 0.75 of tergite (41:55); first tergite smooth basally and apically; mediolateral and median area between dorsal carinae of first tergite sparsely foveolate-punctate (fig. 68); median length of second tergite 0.8 × its basal width (24:31), and 1.2 × third tergite (24:20); second and third tergites shiny and smooth; ovipositor sheath 1.5 × as long as forewing (120:80).   
 Color: Body yellowish brown, scapus brown; antenna brownish yellow basally, with antennal segments 14–22 cream white; palpi yellow; fore- and middle legs yellow; hind leg yellow, with apical third of hind femur and tibia apically infuscate; pterostigma and wing veins brown; wing membrane yellow; metasoma reddish brown; ovipositor sheath dark brown.   
 Male: Unknown.   
 ETYMOLOGY: From laevis (Latin for “smooth, polished”), because of the highly polished mesoscutum.
