Etymology.

The name chiqyaq means green in the Quechua language, referencing the diagnostic green coloration of this species.

Diagnosis.

Beside the features mentioned above to differentiate Gaujonia chiqyaq from G. arbosi , there are also other informative characters to identify this species. The male has a narrow reniform spot outlined by black scales along the upper and lower sides, but not in the middle region. The orbicular spot is small and greenish yellow, outlined in black. The thorax has large black tufts. The female has a larger reniform spot with the same yellow coloration. Forewing transverse lines are more sharply defined and thicker than in G. arbosi .

Description.

Head. Palp with last segment black; frons with a combination of black and greenish yellow scales. Thorax. Covered with long black tufts. Wings. Both sexes greenish yellow with thin spots and lines; forewing length: male: 20-22 mm; female: 28-30 mm; forewing ground color greenish yellow with small, thin lines on venation forming pattern, female with thicker and well-defined lines; orbicular spot in male small, black, but almost imperceptible; orbicular spot larger in female and elongated; reniform spot in both sexes narrow, greenish yellow, outlined in black; both sexes with hindwing venation green, and fringe black with some greenish yellow dots. Leg. Metathoracic and metathoracic legs black with some greenish yellow patches; hind legs greenish yellow with black shading. Abdomen. Brown dorsally with green tufts on A1-A3 and some black scales in middle of the green tufts; ventrally greenish yellow; female similar to male but paler in color. Male genitalia. Cucullar region extended close to saccular region, valva relatively narrow, slightly ridged externally on apex; saccular region rounded at base and process wide; saccus wide V-shaped; juxta rectangular concave on top; tegumen wide; aedeagus short 3 × longer than wide; basal area almost same size as apical part of vesica with two patches of spines, one 2 × narrower than the other. Female genitalia. Anal papilla wide, slightly ridged; posterior apophysis ⅓ × longer than anal papilla; sterigma large oval shaped, fused above ostium; anterior apophysis short; ductus bursae heavily sclerotized and connected to appendix bursae, which is sclerotized as well; appendix bursae ½ × narrower than corpus bursae.

Immature stages.

Distribution.

This species has a broad distribution from Ecuador to Peru between 2100- 3200 m (Fig. 93 ).

Biology.

Unknown.

Remarks.

The holotype of Gaujonia chiqyaq closely resembles the type specimen of Gaujonia arbosi (Fig. 33 ) illustrated by Dognin (1894). However, it is a different species from the lectotype of G. arbosi , differing from it in characters of the male and female genitalia, thus it is here established as a new species. The holotype of Gaujonia arbosi and most of the paratypes are well preserved. Guevara and Romero (2008) misidentified this species as Gaujonia arbosioides , which is placed in a different genus (see Millerana arbosioides remarks).
