Mesoscutal pit present, elongate. Prescutellar depression sculptured, with median and lateral carinae, 1.3 times as long as its maximum width. Precoxal sulcus present, crenulate, reaching anterior and posterior margins of mesopleuron. Posterior mesopleural furrow almost smooth. Propodeum sculptured, with basolateral areas rugose.
