Diagnosis.

Externally, O. xeta sp. nov. can be distinguished from O. jairana sp. nov. by all tibias with a band of long scales with grayish brown apex, while O. jairana sp. nov. presents these scales with light brown apex (Fig. 6A, C View Figure 6 ). Dorsally, the abdomen of O. xeta sp. nov. has a grayish color, while O. jairana sp. nov. has a copper color (Fig. 2C, D, G, H View Figure 2 ). The genitalia of O. xeta sp. nov. presents, in lateral view, a wider socci than O. jairana sp. nov., and the process of sacculus is half the length of that of O. jairana sp. nov. The aedeagus of O. xeta sp. nov., does not have spines, and the basal portion of the vesica is covered by small cornuti (Figs 10 View Figure 10 , 19 View Figure 19 ).

Olceclostera xeta sp. nov. differs from O. quilombola sp. nov. by external and genitalia characters: on the forewing of O. xeta sp. nov. the two subapical hyaline spots, between M1 and M3, are rounded and smaller. Otherwise, these spots are rectangular in O. quilombola sp. nov. Dorsally, the abdomen of O. xeta sp. nov. has a grayish color, while O. quilombola sp. nov. has a copper color (Fig. 2E-H View Figure 2 ). Olceclostera xeta sp. nov. has all tibias with a band of long scales with grayish brown apex, while O. quilombola sp. nov. presents these scales with dark brown apex (Fig. 6B, C View Figure 6 ). The genitalia of O. xeta sp. nov. presents the process of sacculus with half of the length of O. quilombola sp. nov., and the basal portion of the vesica is covered by small cornuti, while the aedeagus of O. quilombola sp. nov. has vesica without cornuti (Figs 17 View Figure 17 , 19 View Figure 19 ).

Olceclostera xeta sp. nov. is similar to O. wayana sp. nov., but slightly darker gray and smaller in size (17 mm forewing length). The subapical hyaline spots are slightly larger. In the genitalia, O. xeta sp. nov. differs from O. wayana sp. nov. by the presence of a protrusion on the apex of the aedeagus.

Description (Figs 2G, H View Figure 2 , 4E, F View Figure 4 , 6C View Figure 6 , 19 View Figure 19 , 20 View Figure 20 ).

Head. Male. As in O. jairana sp. nov. Female. Antenna, pecten shorter than the male’s pecten. - Thorax. Male and Female. As in O. jairana sp. nov. - Legs. All tibias with a band of long scales with grayish-brown apex projecting towards the posterior region (Fig. 6C View Figure 6 ). - Wings shape and venation. Male and Female. As in O. jairana sp. nov. (Figs 2G, H View Figure 2 , 4E, F View Figure 4 ). Male. Forewing length: 16.5-17 mm (n = 03). Upperside and underside: Similar to O. jairana sp. nov. Hindwing. Upperside and underside: Similar to O. jairana sp. nov. Female. Forewing length: 17-21 mm (n = 03); general color similar to the male, the apex is more acute than in males; lighter grey than the female of O. jairana sp. nov. and O. quilombola sp. nov. The hyaline spot between M1-M2 is small than in males, and the hyaline spot between M2-M3 is reduced or absent. Hindwing. As in male. Abdomen. Male and Female. Similar to O. jairana sp. nov., but dorsally gray. - Genitalia. Male. (Fig. 19 View Figure 19 ). Similar to O. jairana sp. nov., but aedeagus without spines; vesica with the basal portion covered by small cornuti. Female. (Fig. 20 View Figure 20 ). Similar to O. jairana sp. nov., but the ostium bursae are broader and the signum leaf-shaped.

Distribution.

Based on museum records, the species is present in the Brazilian states of Paraná and the Paraguayan provinces of Alto Paraná, Canindeyú, Concepción, Cordillera, Hayes, and Paraguarí (Fig. 22 View Figure 22 ).

Etymology.

This species is named after the Xetá indigenous people. The Xetá were original inhabitants of the northwestern Paraná and the last ethnic group in the state to come into contact with white colonizers (in 1954) who invaded their territory and decimated the Xetá population.
