Head: antenna with unknown number of flagellomeres; left antenna broken after 40th flagellomere; right antenna broken after 39th flagellomere. Mesosoma: scutellar sulcus lacking longitudinal carina (cf. 6d); projection of propleuron blunt (cf. Fig. 6 f); median areola of mesosoma slightly depressed medially with sharp carinae laterally and posteriorly (cf. Fig. 7 c); propodeal sculpture reduced to small protuberance anteromedially (cf. Fig. 5 f); mesopleural suture with transverse carinae along its length; margin between metepimeron and metepisternum with 4 strong transverse carinae (cf. Fig. 7a); carina bordering subpronope posteriorly, extending to anterior margin of pronotum (cf.
