Abdomen castaneous , supra-anal lamina trigonal , not exceeding 

 the sub-genital lamina which at the apex is squarely emarginate ; 

 no genital styles. Abdomen beneath with the disc paler. Cerci 

 very long, 3 apical joints slender. Legs sordid testaceous, front 

 femora with a complete row of spines on the anterior margin 

 beneath, the more proximal spines shorter. 



Total length 16 mm; length of body 13 mm; length of teg- 

 mina 14 mm; pronotum 3x3,9 mm.
