Further specimens studied. BRAZIL. SURUMU: Rio Branco (1 female, NMPC).

Diagnosis. This species somewhat resembles T. (T.) albopilosum in its colouration, short antennae and bodyshape, but it differs in the short frontal pubescence, shape of the pronotum which possesses angulate lateral margins ( Fig. 9 ) and in the form of the elytral epipleura which are wide but not reaching elytral suture and not visible from above; aedeagus more slender, parameres with large preapical spines ( Fig. 68 ).

Length: 3.4–4.8 mm.

Bionomy. Unknown..

Sexual dimorphism. Female differs from male in the rather intense blue or violet lustre of the entire dorsal surface.

Distribution. Brazil, Prov. Roraima.

Note. The length of the type specimens given in the description ( Cobos, 1972) (3–4 mm) does not correspond with the real size of the type specimens studied which was 3.4–4.8 mm.
