3. Body with short, broad, blunt, much flattened and strongly appressed glittering silvery hairs ( Fig. 2 View Fig D–F)....................................................................................................................................4 – Body without such hairs, only with sparse simple appressed pubescence ( Fig. 2 View Fig G–H)...............6

T. galoasanum Santschi, 1910 View in CoL – Appressed pubescence sparse and spaced out, not strap-like and not overlapping ( Fig. 2 View Fig D–E)...5
5. The base of the first gastral tergite in profile forming a thick, laterally projecting downcurved flange, which obscures the tergosternal suture basally and base of the sternite; reddishbrown or red species ( Fig. 3A View Fig ) ........................................................ T. setuliferum Emery, 1895 View in CoL
