 fovea is present in two examples, and may be accidental] ; 

 abdomen subpetiolate, as long as the head and thorax 

 united, the base of abdomen apparently not striolate ?. 



Length barely i mm, 



Foerster divides the sub-family Platygasterina into 21

 species fit into any of the divisions, and therefore place it in 

 Platygaster^ sensu lat. The '' generic " characters are as

 the club joints longer than the others ; the last joint conical, 

 nearly twice the length of the penultimate, the other club
