Thorax 593-665 (average 637) \x long. Prothorax. Pronotal ridges strong, but medially interrupted by weak sclerotization. Lateral pronotal sclerites small, without setae. Medial pronotal setae absent. Post-tergites small, without striations and without setae. Pleural structures typical of family. Sternum with strong transverse ridge, a median ridge which is occasionally interrupted in the middle, and a well sclerotized triangular sclerite. Anteprosternal setae absent ; prostemal setae : occasionally one on each side. Mesothorax. Mesoprephragma with shallow emargination. Prescutum more than twice as wide as long (average 228 and 90 a. respectively) ; anterior margin curved ; laterally bounded by the prescutal ridges and posteriorly by the prescutal suture ; with polygonal reticulation ; slightly more heavily sclerotized medially.
