Morphometric data. Male (n=7) forewing length: 9 mm.

Remarks. Our material has the same pattern of spots on the head, pronotum, and wings as illustrated by Ribeiro & Rafael (2009) ( Figs. 3A and 3C ). The penial armature of the male seems to vary, with the apex of our specimens in lateral view strongly rounded ( Fig. 3F ), different from the tapered and acute apex illustrated by Froehlich (2001) and Ribeiro & Rafael (2009). This species is widespread, reported from areas covered by tropical savanna or Cerrado in the states of Maranhão, Mato Grosso and Tocantins; and by Amazon Forest in the states of Amazonas and Roraima ( Ribeiro & Santos 2018; Rippel et al. 2019; Menezes et al. 2020) ( Fig. 1D ). In the State of Maranhão, the species is also widespread, occurring in the East (municipality of Codó), South (municipality of Carolina), and West of the State (municipality of Imperatriz) ( Fig. 1D ).
