 (nothing like so much as in Paltothyreus), the lateral margins of the 

 median area tumid, hardly carinate, the space between almost flat or 

 only very shallowly concave, not deeply excavated as in Glyphopone, 

 s. str. The clypeus is produced backwards between the frontal carinae, 

 and is confluent with the frontal sulcus, which extends almost to the 

 anterior ocellus. Antennae 12-jointed, the scape widening towards 

 the apex, strongly compressed or flattened along its whole length. 

 Abdomen elongate, as long as the head and thorax. Wings with 2 

 closed cubital cells, 2 discoidal and 1 submedian (in the type of the 

 genus there are 3 cubital, 2 discoidal and 2 submedian, one of the 

 latter very small). Tibiae and metatarsi of middle pair of legs, and 

 the metatarsi of the hind pair of legs furnished with rows of spines. 

 All the femora compressed laterally, the anterior femora strongly so.
