Tabanus platycerus Fairchild  ; Cárdenas & Vieira, 2005: 155 (misident.), Cárdenas et al., 2009: 528 and appendix 4: 19 (misident.); Henriques, 2016: 182 (misident.).

Diagnosis. Frons strongly divergent (D.I.> 2.0). Notopleuron integument paler than adjacent scutum, this and scutellum black. All coxae and femora dark brown to black. Middorsal abdominal stripe a series of connected triangles through tergite 5, sometimes with faint indications at 6. Dorsolateral a series of disconnected triangles visible through tergite 6.

Comments. This species can be differentiated from T. trivittatus  and T. callosus  , sympatric species, by the notopleuron with integument paler than adjacent scutum. We found that the coxae integument of T. sextriangulus  ranges from yellowish brown to black in the females examined. This variation is not accounted for in the species description of Gorayeb & Rafael (1984). However, this variation, does not difficult species determination, since the fore coxa is always darker than the remaining coxae and the femora is always darker than tibiae.
