[Xanthippus and Cratypedes will key to this point if the anterior incision of the median carina is very weak; the middle of the pronotum is collapsed between the two incisions in Xanthippus, or anterior to the incision if only one incision is visible; the median carina is distinct and not crumpled or collapsed except for one distinct incision in Pardalophora. Cratypedes can be distinguished from Pardalophora by the pattern on the tegmina. Pardalophora has discrete, fairly large dark spots; Cratypedes tends to have indistinct, irregular spotting patterns.]
J' Spots on tegmina few; dark area within "V" not present; anterior extremity of fastigium of vertex prolonged.
