Diagnosis. Postpedicel as wide as long. Frons not markedly divergent above (D.I. 1.8). Notopleuron paler than adjacent scutum. All legs yellow, fore tibia weakly bicolored. Middorsal stripe series of continuous triangles. Dorsolateral abdominal stripes broad, continuous to tergite 3, interrupted through tergite 6. Comments. Fairchild (1976) described this species and pointed out to the resemblance with T. restrepoensis and T. tristichus . T. isis may be differentiated from the both species by darker integument of the scutum and abdomen; middorsal stripe narrow and irregular. From T. restrepoensis by fore tibia weakly bicolored. From T. tristichus , which also has weakly bicolored fore tibia, by the more divergent frons and ecological habits, since T. tristichus seems to be restricted to coastal areas. Material examined.
