Characters : Since this genus is the type genus of its tribe, it shows very distinctly, as would 

 be expected, the fundamental characters of that tribe, especially the strong, simple suprahumerals, the 

 slender posterior process extending high above the body, the unarmed mesonotum, the plainly visible 

 scutellum and the four apical cells of the hind wings. From the other genera of the tribe it differs
