 middle of each cell, except the costal, subcostal, and some of the apical cells 

 of the tegmina. 



Genital styles small, short ; anal segment small, sunk into a quadrate 

 emargination of the pregenital tergite, the ventral edge of anal segment drawn 

 out into a small lip, two small, thin, flat processes arise from beneath the lip 

 and project slightly beyond the edge ; pregenital plate large, in profile the 

 basal portion convex, the median third of the hind margin produced into a 

 subquadrate flat plate, the sides of which are short and slightly converging, 

 the apex broadly angular.

Genital styles large, long; anal segment large, the ventral edge projecting 

 as a wide quadrate lip, which is produced into two long narrow processes 

 reaching to near the apex of the genital styles ; pregenital plate large, the hind 

 margin produced into a large plate much longer than wide, the base wider than 

 the apex, the apex truncate, and the sides convex in the middle.
