Measurements data. Female forewing: 12.5–16.5 mm, n= 33; male forewing: 9.6–11.9 mm, n=38.

Remarks. Specimens studied here are smaller (forewing length of male: 10–14.5 mm) and lighter than that studied by Baldin et al. (2013). Additionally, our specimens possess a yellow spot medially on the head and the Mline is not as distinct as that observed in specimens from other areas of Brazil. Even with such differences, due to wide distribution of A. debilis we consider these differences as intraspecific. Regarding the penial armature of this species, its apical portion in lateral view is similar to the illustration in Zwick (1972) and differs slightly from Baldin et al. (2013). This species is recorded to northeastern Argentina (provinces of Misiones and Entre Ríos), Paraguay, and southern to northeastern Brazil (Duarte & Lecci 2016). This is the first record of this species for Tocantins State.
