 Antennae 13-jointed, long, inserted below the middle of the face ; the scape, 

 cylindrical, less than one-third the length of the flagellum, the latter long, 

 subclavate, the pedicel shorter than the first funicle joint. 



Thorax similar to Eupelmus, only the prothorax is longer, while the 

 scutellum and mesonotum are more depressed and do not meet in an 

 elevation or ridge; wings undeveloped, scale-like; legs as in Eupelmus, 

 except the anterior femora are mrch swollen, shorter and much stouter
