piceous vitta covering half of each elytron and uniting at apex. 

 Body beneath and legs entirely pale, anterior coxal cavities open, 

 claws appendiculate. Length 3.6 mm.; width 1.5 mm. 



Type, female, BMNH, from Ega, Brazil. 



Remarks: This is closely related to T. rhabdota from Colombia 

 and T. nymphaea (Jacoby) from Panama, but differs from either in 

 the elytral pattern with the elytral vittae joined at the apex. Although 

 only a female is known, the male will undoubtedly have notched 

 middle tibiae.

 and closely resembles T. biplagiata Blake in coloring but lacks the 

 pale elytral spots and the aedeagus is quite different.
