These three specimens are also identical to each other; they are probably a third species. Although similar to species A, they differ from it and from T. bonairensis in the following characters: eye as in species A, more vertical-oblique compared to horizontal-oblique as in T. bonairensis; paraverticals present and convergent, arista dark to base; yellow thorax with dark declivity on anterior margin above neck and dark mediotergite; narrow bands on tergites 2–5 and lateral spots on tergite 6. The chaetotaxy of head and thorax is the same as in species A.
