The forewing membrane has amber infuscations on the area adjacent to crossveins, and apical forks of longitudinal veins. These marks may be from faint to well-marked. On the male genitalia, the gonocoxite IX is thin, short, and strongly curved medially, with base inwardly curved; the apex is curved lateroventrally with two processes, of which the shorter, preapical one lies dorsally; a third shorter process may be present. On the female genitalia, the gonapophyses VIII medial part is quadrangular, with a posteromedial bifid process; the lateral part is an oval plate, with convex ventral surface, covered with microspinules.Description.Measurements.

It was originally described from Peru (probably Ica) and was until now known only by the lectotypes. Herein, the first records from Bolivia, Brazil, Ecuador, French Guiana, and Trinidad and Tobago are presented. This species was also previously registered from Panama as T. iridella by Ardila-Camacho et al. (2018). Additionally, herein the range of distribution in Peru is extended to the provinces of Huánuco, Lima, and Madre de Dios.Most of the records presented by Penny (1982 a) of T. iridella are probably of this species, although because it was not possible to study the specimens of this genus deposited in the Instituto Nacional de Pesquisas da Amazônia (INPA), it is not possible to corroborate the identifications made by this author.This species is sometimes difficult to separate from other Amazonian congeners due to its general coloration pattern, sometimes with completely hyaline wings. The coloration of the pterostigma and the apically bifid male gonocoxites IX can help to recognize this species easily.
