IT= internal tubercles; PfR= posterofrontal ridges; LpA= lateroposterior areas; LpT= lateroposterior tubercles; SoF= supraocular fossa; PP= postorbital pits c Sternum of O. crassulus. The white arrow indicates the smooth prepimeron and the bare anterior corners of metasternum; the black arrow indicates the patch of strong punctations posterior to the metasternal disc d Sternum of Proculejus brevis. The red arrows are signaling the absence of anterior profemoral groove. The white arrows indicate the chagreened (“greasy”) prepimeron and the slightly setose anterior corners of metasternum.
