The only described species known to me which resembles this species is T. platyderus 

 (Bates), from the Amazons, which differs only in being decidedly larger, and in the elytra 

 having two deeply impressed striae on each side of the suture. I do not recognize the 

 species in any of the descriptions of North- American Tachys by Leconte. The width 

 of the thorax is about equal to twice the length. The insect, together with the following, 

 has some resemblance to T. globulus, Dej., but they are much less convex.
