Size medium small, form extremely slender. Head with paired 
impressions on frons, occiput showing impression at sutures. Pronotum very 
small, decidedly narrower than head, considerably longer than wide ; prozonal 
portion moderately convex to very narrow lateral portions, defined from 
metazona by a broadly convex sulcus ; metazona narrow, feebly convex with 
caudal margin cingulate and broadly convex ; lateral margins of pronotum 
cingulate, faintly converging caudad, terminating at latero-cephalic angles in a 
small acute-conical projection directed dorsad and weakly laterad. Tegmina 
decidedly broader than head, full, with caudal margin transverse. Wings very

strongly projecting. Abdomen smooth, moderately convex dorsad. Ultimate 
tergite simple, slightly longer than its apical width, slightly impressed meso- 
caudad. Pygidium minute, strongly declivent, in dorsal aspect appearing 
rounded and with projection equal to width. Forceps very elongate and 
slender, straight and subattingent to near apex with ventro-internal margin 
very narrowly lamellate and serrulate, this becoming gradually verv weak 
distad, this terminating suddenly at less than distal quarter with inner surface 
then weakly concave to a ventro-internal tooth situated mesad in this section 
thence concave due to the shaft curving inward from that, point to the acute 
apex. Penultimate sternite broader than long, lateral margins convergent, 
rounding into the very feebly concave, truncate apex. Caudal tarsus only one- 
third as long as caudal tibia.
