Mesosoma . Pronotal anterior carina obsolete, anterior half of pronotum with sparse punctures, posterior half smooth; pronotum latero-ventrally with dense oblique striae; mesoscutum medially with dense punctures, laterally sparser; mesopleuron with small and dense punctures, somewhat reticulate; mesoscutellum and metanotum with sparse punctures ( Fig. 31 ); propodeal dorsal face ( Fig. 31 ) with dense crenulations, without submarginal carina and posteriorly with short longitudinal striae connecting transverse carina; propodeal areola ( Fig. 31 ) subrectangular, weakly convergent posteriorly, APWL =3.4: 2.4: 4.2, medial longitudinal carina reaching posterior 2/3 of areola; lateral surface of propodeum dorsally with dense long oblique wrinkles, ventrally with dense minute punctures; posterior surface of propodeum granulated, without medial longitudinal carina; tegula atmost slightly longer than middle width, posterior margin without transverse impressed line; apex of marginal cell of forewing ( Fig. 28 ) not exceeding second submarginal cell.

Metasoma. Anterior half of T 1 ( Fig. 28 ) with sparse shallow punctures; subposterior area of T 1 close to apex and slightly depressed, with 2 transverse rows of punctures; S1 ( Fig. 33 ) anteriorly with coarse and deep punctures, posteriorly smooth, without posterolateral groove; T 2 anteriorly with costate transverse depression ( Fig. 28 ); T 3– T 6 anteriorly with dense punctures, posteriorly sparser; S2–S5 with sparser punctures than T 3– T 6; S5 ( Fig. 32 ) with lateral denticle, and without deep orifice.
