Description.
Holotype, female, body length 12.0 mm, fore wing length 9.4 mm, antenna 17.6 mm, ovipositor sheath 13.4 mm (Fig. 3 View Figure 3 ).
Head. Antenna with 51 flagellomeres; first flagellomere 1.3 × second one; length of first and second flagellomeres 3.8 and 4.4 × their widths, respectively; length of subapical antennomere 2.7 × its width; in frontal view, width of face 0.8 × its length (Fig. 4B View Figure 4 ); length of maxillary palp 2.0 × height of head; face densely punctate medially, sparsely punctate laterally (Fig. 4B View Figure 4 ); malar space 0.9 × as long as basal width of mandible; clypeus slightly convex ventrally, sparsely finely punctate (Fig. 4B View Figure 4 ); distance between tentorial pits 1.3 × distance from pit to eye margin; in dorsal view, width of head 2.2 × median length; temple short, smooth, eye 15.5 × temple; ocelli large, OOL: OD: POL = 6: 9: 9 (Fig. 4A View Figure 4 ); frons smooth.
Mesosoma. Length of mesosoma 1.4 × its height (Fig. 4E View Figure 4 ); pronotal trough finely and densely crenulate medially, shiny smooth dorsally, finely punctate ventrally; propleuron densely punctate (Fig. 4E View Figure 4 ); middle and lateral lobes of mesoscutum mostly coriaceous, with sparse fine punctures; notauli crenulate anteriorly, strongly converging posteriorly in a sharp V-shaped depression, divided by mid-longitudinal rugosity (Fig. 4D View Figure 4 ); scutellar sulcus wide, with one median carina, 0.5 × as long as scutellum; scutellum convex, rugose-punctate; mesopleuron densely punctate (Fig. 4E View Figure 4 ); metapleuron rugulose; propodeum reticulate-rugulose (Fig. 4C View Figure 4 ).
Wings. Length of fore wing 5.2 × its maximum width; length of pterostigma 5.2 × its width; fore wing vein SR1 2.2 × as long as vein 3-SR; r: 3-SR: SR1 = 12: 37: 80; vein 1-CU1 quadrate; cu-a: 2-CU1 = 11: 52; 2-SR: 3-SR: r-m = 21: 37: 10; second submarginal cell of fore wing narrowed distally; hind wing vein 2-SC+R thick, nearly quadrate; vein 1-M weakly curved basally; hind wing vein cu-a: 1-M: 1r-m = 22: 22: 16; vein SR strongly bent basally (Fig. 4F View Figure 4 ), and marginal cell largely glabrous basally, wider medially than basally and apically, parallel-sided medially and distinctly widened apically (Fig. 4F View Figure 4 ).
Legs. Hind coxa densely setose latero-ventrally, but without setae dorso-apically; length of femur, tibia, and basitarsus of hind leg 9.1, 17.0, and 12.3 × their maximum widths, respectively; left hind trochantellus with four teeth apically (Fig. 4H View Figure 4 ); length of hind inner and outer tibial spurs 0.4 × and 0.3 × hind basitarsus, respectively; length of hind basitarsus 0.4 × hind tibia and as long as second-fifth tarsal segments combined.
Metasoma. Length of metasoma 1.6 × head and mesosoma combined; first tergite deeply concave medio-basally (Fig. 4G View Figure 4 ), length of first tergite 3.6 × its apical width; median length of second tergite 1.1 × third tergite; first metasomal tergite transversely striate basally, transverse-obliquely striate medio-subapically, obliquely striate at apex; second tergite with convergent striae on most part of tergite, but with parallel striae apically (Fig. 4G View Figure 4 ); third tergite with fine striae, mostly smooth apically; remaining metasomal tergites sparsely punctate, with sparse long setae; length of ovipositor sheath 1.4 × fore wing.
Colour. Head dark brown; palpi yellow; scapus and pedicellus dark brown; flagellum brown with flagellomeres 8th-18th yellow; mesosoma brown; wing veins yellowish brown; tegula yellow; parastigma, pterostigma basally and apically yellow; wing membrane hyaline; fore and middle legs yellow; hind coxa (except apically brown), trochanter and trochantellus yellow; hind tibia brown, except yellow at base; hind tarsus and tibial spurs yellow; metasoma blackish brown, except basal 1/2 of first and third tergites pale yellow; ovipositor sheath brown; ovipositor yellow.
Male. Unknown.
Biology.
Unknown.
Etymology.
From glaber (Latin for hairless), referring to the hind wing with both the basal cell apically and the marginal cell basally glabrous.
Distribution.
S Vietnam (Dong Nai province) (Fig. 16 View Figure 16 ).
Notes.
This new species can be distinguished from other species by the following characters: marginal cell of hind wing largely glabrous basally, and vein 1-CU1 of fore wing quadrate.
