Mesosoma . Pronotal anterior carina complete, anterior half of pronotum ( Fig. 48 ) with sparse punctures, posterior half impunctate; pronotum latero-ventrally with dense oblique striae; mesoscutum ( Fig. 48 ) with sparse punctures, punctures gradually denser from anterior to posterior area; mesopleuron with sparse punctures; mesoscutellum and metanotum with sparse punctures; propodeal dorsal face ( Fig. 48 ) with dense crenulations, without submarginal carina and posteriorly with short longitudinal striae connecting transverse carina; propodeal areola ( Fig. 48 ) rectangular, APWL =3.2: 2.6: 4.3, medial longitudinal carina reaching posterior 1/2 of areola; lateral surface of propodeum dorsally with dense long oblique wrinkles, ventrally impunctate; posterior surface of propodeum with denes minute punctures, without short medial longitudinal carina; tegula atmost slightly longer than middle width, posterior margin without transverse impressed line; apex of marginal cell of forewing ( Fig. 45 ) distinctly exceeding second submarginal cell.

Metasoma. Anterior half of T 1 ( Fig. 49 ) with sparse shallow punctures; subposterior area of T 1 close to apex and slightly depressed, with a few scattered punctures; S1 ( Fig. 47 ) anteriorly strongly arched, with several sparse punctures and posterolateral groove; T 2 anteriorly with costate transverse depression ( Fig. 49 ); T 3– T 6 ( Fig. 45 ) with dense punctures, punctures gradually sparser from anterior to posterior area; S5 with lateral denticle, and without deep orifice.
