Remarks. By having well-developed lateral lobes, low mesepisternal tubercles, and paraprocts about as long as cerci, T. yanomami belongs in the mammilaris species group, together with T. geijskesi, T. karitiana, T. mammilaris, and T. tirio . It can be separated from these species by characters given in the keys. Male of T. yanomami is close to T. mammilaris, but female is closer to T. tirio . The three type specimens described by De Marmels (1992) were collected in the forest on sun-hit bushes, away from water. This is the first record of this species from Brazil.
