DIAGNOSIS: Antenna with 35 segments and antennal segments 10–18 cream white; frontal protuberance lamelliform and acute dorsally; height of eye 1.55 × width of temple in lateral view. Mesosoma 1.9 × longer than high (in lateral view); notauli deep, crenulate anteriorly, posteriorly areolate-rugose and with a median carina; propodeum without areola, coarsely rugose. Foretarsus 1.3 × as long as foretibia; length of forewing 3.3 × its maximum width; vein 3-SR 1.15 × vein r; vein 2-M 2.3 × 3-SR; hind wing vein 1-M 0.95 × vein 1r-m; basal cell distinctly widened apically; vein 2-SC+R vertical; hind wing with four hamuli. Hind femur only with ventral serrations; length of hind femur 3.5 × its maximum width (without serrations); outer side of hind coxa and femur sparsely finely punctate. First tergite short, 0.9 × as long as its apical width; dorsal carinae present in basal 0.4 of tergite; median length of second tergite 0.5 × its basal width and 1.2 × third tergite; first tergite foveate-rugulose medially, largely rugose laterally; second tergite punctate-reticulate medially and rugose-punctate laterally.
DESCRIPTION: Holotype, ♀, body length 8.4 mm, antenna 6.2 mm, forewing length 6.9 mm, ovipositor sheath 7.0 mm (fig. 1).
Head: Antenna with 35 segments; third antennal segment 1.1 × as long as fourth (16:14); in anterior view height of eye 2.6 × as long as its transverse width (34:13); width of face 2.2 × length of face and clypeus combined (50:23); malar space 0.75 × as long as mandible width (15:20) and 0.6 × height of eye (20:34) (fig. 3); maxillary palp missing; distance between tentorial pits equal to distance from pit to eye margin; in dorsal view width of head 1.7 × its median length (80:47); height of eye 1.55 × as long as temple (28:18); POL:OD:OOL = 9:7:16; distance between anterior and posterior ocelli 0.25 × as long as OOL (4:16) (fig. 2); frontal protuberance lamelliform and acute dorsally (fig. 4); in lateral view length of eye 1.4 × its transverse width (36:26); transverse width of eye 1.4 × width of temple (26:19) (fig. 5); face coarsely rugose; frons, vertex, and temple almost smooth, somewhat coriaceous.
Mesosoma: Mesosoma 1.9 × longer than its height (79:42) (in lateral view); pronotal side crenulate anteriorly and medially, rugose ventrally and dorsally; mesopleuron almost flat, coriaceous (fig. 7); metapleuron areolate-rugulose; notauli deep, crenulate anteriorly, posteriorly areolate-rugose with a coarse median ruga (fig. 6); median lobe of mesoscutum smooth anteriorly, foveolate-rugose posteriorly; lateral lobes of mesoscutum almost smooth; scutellar sulcus deep, with carinae, 0.75 × as long as scutellum (12:16); scutellum narrowed laterally, coriaceous; propodeum without areola, transversely rugose (fig. 8).
Wings. Forewing: length of forewing 3.3 × its maximum width (116:35); pterostigma 3.5 × longer than wide (46:13); vein r arising from middle of pterostigma (16:30); vein 3-SR 1.2 × vein r (15:13); r:2-SR:3-SR:SR1:r-m = 13:20:15:83:19; vein cu-a oblique, 1-CU1:cu-a:2- CU1 = 5:14:23; second submarginal cell trapezium-shaped, long base 2.3 × as long as short base (35:15) (fig. 12); hind wing vein 1-M 0.95 × as long as vein 1r-m (19:20); basal cell distinctly widened apically; vein 2-SC+R vertical (fig. 13); hind wing with four hamuli.
Legs: Foretarsus 1.3 × longer than foretibia (55:43); hind femur with ventral serrations, without tooth-shaped protuberance (fig. 10); length of hind femur (without serrations), tibia, and basitarsus 3.5 (56:16), 8.3 (75:9), and 6.5 × (26:4) as long as their maximum width, respectively; hind tibia distinctly curved subbasally (fig. 9); hind basitarsus 0.8 × as long as hind tibia (59:75); hind basitarsus 0.74 × as long as hind tarsal segments 2–5 (26:35); fourth hind tarsal segment 0.40 × as long as telotarsus (4:10); outer side of hind coxa and femur sparsely finely punctate (figs. 9, 10).
Metasoma: Metasoma 0.7 × as long as head and mesosoma combined (34:50); first tergite short, 0.9 × as long as its apical width (46:49) (fig. 11); dorsal carinae present in basal 0.4 of tergite (20:46); median length of second tergite 0.5 × as long as its basal width (24:51), and 1.2 × as long as third tergite (24:20); first tergite foveate-rugulose medially, largely rugose laterally; second tergite punctate-reticulate medially and rugose-punctate laterally; third tergite smooth (fig. 11); ovipositor sheath slightly longer than forewing (70:69).
Color: Body black, scapus brown; remainder of antenna brown with third and fourth segments yellow and segments 10–18 cream white; palpi pale yellow; fore- and middle legs yellow, except whitish yellow tarsus; hind leg yellow, but hind tarsus whitish yellow, femur and tibia apically dark brown (figs. 9, 10); pterostigma brown; wing veins brownish yellow; wing membrane hyaline (figs. 12, 13).
Male: Unknown.
ETYMOLOGY: From angulus (Latin for “corner, bend”), because the mandible is angularly bent ventrally.
