and carinate dorsally, anterior margins not declivous; clypeus convex, 

 muscle impressions distinct, dorsomedian area granulate; transclypeal 

 suture incomplete; face pubescent below; clypellus not produced, its 

 contour continuing profile of clypeus. 



Thorax with pronotal width less than transocular width of head, 

 lateral margins parallel, disc transversely rugose and punctate, posterior 

 margin concave, in lateral aspect with a complete dorsopleural oblique 

 carina; scutellum transversely striate on posterior portion. Forewing 

 with membrane not clearly delimited, veins elevated and distinct,

Male genitalia: Pygofer moderately produced, apical margin 

 rounded, disc with numerous microsetae on posterior two-thirds,
