Venezuela , Amazonas Federal Territory and Brazil , State of Pará. 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 .
