 the metapleurse with only 8 semi-oblique keels at the top ; 

 apex of abdomen not densely covered with fulvous hair.

The area on the median segment distinctly longer than

T.fulvohirta, 



Head shining, rather thickly covered with longish

 separated; the post-scutellum punctured like the scutellum, 

 but with the punctures smaller. The central area on the 

 median segment with two keels : the space inside them 

 transversely, rugosely punctured, except for a small shining
