Head, lateral view.   FIGURE 28.  T. glaucusdistribution. Black: previously known distribution; Red: new records.  Type-locality:“ Brazil”   Diagnosis:Large specimens ( 18.7–23 mm). Frons narrow (FI: 4.7–5.8), divergent at base or nearly parallel (DI: 0.82–1.05); palpus mostly covered with black setulae. Wing brown infuscated, costal cell orange, never with a cloud on the fork of vein R 4+5. Scutum and scutellum with integument black and gray pruinosity. Femora black or at least darker than the tibiae. Abdomen orangish-brown, nearly always with a black dorsomedial integumental stripe (tergite 1 to 2 or sometimes more), dorsomedial pale triangles (tergite I to VI) and dorsolateral spots (tergite I to VI) of yellow or orange setulae when well-preserved.   Remarks:  T. glaucusresembles  T. nebulosus, differing by having a darker integument on the scutum, scutellum, and femora, a parallel or divergent frons at the base, wing brown infuscated with an orange costal cell, and never with a brownish cloud in the fork of vein R 4+5, abdomen usually presenting a black integumental stripe on the first two segments, dorsomedial triangles narrow and dorsolateral spots.  T. nebulosususually has lighter integument on the scutum, scutellum, and femora, frons almost always convergent at the base, wing with light brown clouds at crossveins and in the fork of vein R 4+5, costal cell hyaline or at most pale yellow, abdomen rarely have an integumental stripe on the first tergites, dorsomedial triangles broader and fainter, dorsolateral spots broader and rarely connected. The male is similar to the female, except for the reduced mouthparts, slender antenna lacking the ventral angle found in females, holoptic eyes with the facets well-demarcated, the largest ones occupy the the upper half of the eyes and are lighter than the smaller ones. This species has a wide distribution in South America and this is the first record for the state of Minas Gerais.   Examined material:  BRASIL, Tocantins, Pq.
