Face almost smooth medially, finely granulate laterally (Fig. 2); frons slightly depressed medially, with fine striae near antennal sockets; vertex with fine transverse striae; temple almost smooth. Mesosoma. Length of mesosoma 1.6 × as long as high (54: 34); pronotal side smooth; mesoscutum shiny, almost smooth; notauli deep, narrow; posterior depression of mesoscutum slightly depressed (Fig. 4); prescutellar sulcus with one median carina, 0.7 × as long as scutellum (4: 6); scutellum smooth; precoxal sulcus shadow, smooth; mesopleuron largely smooth (Fig. 5); metapleuron finely granulate; propodeum with faint median carina, granulate entirely (Fig. 8).

Male: Unknown.
description
Variation. Paratypes: antenna with 45 – 53 antennomeres; first tergite 1.0 – 1.1 × as long as apical width; medial length of second metasomal tergite 1.4 – 1.7 × as long as third tergite medially; body length 3.6 – 5.7 mm; fore wing length 3.7 – 4.8 mm; vein 1 - M of hind wing 1.1 – 1.6 × as long as vein M + CU.
diagnosis
Comparative diagnosis. Antenna long, apical antennomere acuminate (Fig. 7); occipital carina narrowly interrupted medio-dorsally (Fig. 1); vein 1 - M of fore wing distinctly curved basally; vein cu-a perpendicular; vein 1 - M of hind wing 1.4 – 1.7 × as long as vein M + CU; propodeum finely granulate entirely; first metasomal tergite slightly longer than its apical width, without median carina; surface of first-third tergites finely granulate (Fig. 10).
etymology
Etymology. From “ granum ” (Latin for seed, small kernel), because surface of propodeum and first-fourth tergites finely granulate.
