 Sterigma not modified and membranous. Anapophyses rather short 

 and slender straight rods, base flattened, dilated and rounded. 

 Postapophyses with a similar base, but very slender elsewhere, little 

 sclerotized, top dilated so as to form a rhomboidal small plate. 

 Abdominal segments from the 6th on, sclerotized, their anterior edges 

 WTinkled.
