Mesosoma. Mesoscutum finely rugose; notauli weakly present; mesopleuron finely rugose; scutellar sulcus present, rugose; mesoscutellum flat, finely rugose; propodeum areolate; propodeal tubercles absent; ratio of mesosoma height to its length 0.7; ratio of hind tibia to hind tarsus 1.1; ratio of length to width of hind coxa, hind femur, hind tibia, and hind tarsus 2.0, 2.1, 4.0, and 11.2, respectively; ratio of posterior spur to basitarsus of hind leg 0.2; fore wing: SR-1 straight; 2-R1 absent; ratio of length of 1-R1 to length of pterostigma 1.5; ratio of width to length of pterostigma 3.3; ratio of r:3-SR:SR-1 1.0:1.0:6.0; ratio r:r-m:2-SR 1.0:1.1:2.4.
