The females have head and pronotum dark, moderately shining; 

 the tegmina and wings shining black, with a metallic, purplish sheen. 

 The pygidium is deelivent proximad, the ventral portion produced, 

 quadrate, with distal margin truncate, but showing three small, 

 triangular productions. The forceps have a decided lamellate 

 production of the internal margin which ceases abruptly at the base 

 of the strongly incurved apices, this margin armed with a blunt 

 median tooth and with minute denticulations in proximal half, these 

 more numerous proximad. The caudal tibiae are armed disto-ventrad 

 with two minute, but stout, spines. The caudal metatarsus is shorter 

 than the third tarsal joint, and has the ventral surface fringed 

 internally with a row of lamellate plates (agglutenated hairs) and 

 externally with a row of minute, but stout, spines. Length of body, 

 8.2 to 8.5; of forceps 2.2 to 2.3 mm.
