description: Theritas Hübner, 1818
Type species: Theritas mavors Hübner
Theritas as reclassified here is a small, widespread Neotropical genus of five species. Theritas mavors and T. triquetra are common, primarily lowland forest species that replace each other geographically. Theritas paupera, T. harrietta, and T. drucei are South American montane forest species that also replace each other geographically.
Theritas is sister to Arcas and is characterized by five synapomorphies (Table 1, Fig. 8). It is most readily recognized by the color of its wings, despite the substantial variability within species. Males are greenish-blue dorsally and have a distinctive muted green ground color ventrally (Figs. 1 and 12). Denivia phegeus is the only other Atlides Section species with superficially similar male coloration. Females have brown scaling dorsally and ventrally (except for T. harrieta). In flight, the brown females somewhat resemble satyrine butterflies (Nymphalidae). Denivia hemon is the only other Atlides Section species with similar female coloration.

Synonymy. Bálint and Wojtusiak (2007) proposed that T. paupera consists of two species distinguished by the presence/absence of a dorsal forewing scent pad and by color of the ventral wings. In the study series for this paper, the scent pad varies from absent to a few scales at the posterior disco-cellular vein (cannot be seen without the aid of a microscope) to enough scales to cover the lower disco-cellular vein to sufficient scales to cover both the lower and middle disco-cellular veins. Bálint and Wojtusiak did not address the hypothesis that scent pad size in T. paupera is variable, including absence. Further, Bálint and Wojtusiak suggested that presence of a scent pad was correlated with wing color, but we found no correlation in the study series. The description of T. gozmanyi was also problematic for another reason. The authors claimed without evidence that the male of T. paupera lacks a scent pad, but the holotype of T. paupera is a female. Even if there were two distinct biological species—and we know of no compelling evidence to support such a hypothesis—we do not know to which species the name T. paupera would apply.
Theritas harrietta (A.G. Weeks, 1901) (Thecla), type locality: Bolivia
Distribution and Habitat. Southern Peru (Cosñipata Valley) to Bolivia in montane forest.
Theritas drucei (Lathy, 1926) (Thecla), type locality: Brazil (SC)
Distribution and Habitat. Brazil in montane forest from RJ to SC. It occurs at lower elevations in the south of its range.
