Type material.

Holotype ♂, Ecuador: Ecuador, Cotopaxi Prov., Minitrack Station paramo S of Machachi, 12,000', 10 Apr. 1958, coll. R. W. Hodges. Deposited in CUIC. Paratypes (4 ♂, CUIC): Ecuador: Same collecting data as holotype.

Etymology.

The species was named after my friend Kyhl Austin, an American lepidopterist, who found this species in the dark corners of the CUIC.

Diagnosis.

Millerana austini is similar to M. cajas , but it can be differentiated by the antemedial line, which is formed by a single line, whereas M. cajas has two. The male genitalia are without protuberances on the outer margin, except for two extensions; one near the apex and the other on the lobe; they are similar to those of M. tigrina ; however, the outer margin of the valve is concave in M. tigrina .

Description.

Head. Palp black with a small line with pale yellow underneath; frons yellow. Thorax. Dark yellow with dots in black. Wings. Forewing dark yellow with black pattern; length 17-19 mm. All lines well developed with exception of terminal line; orbicular spot circular; reniform spot incomplete, with a small lunate marking; V-shaped mark on base of CuA2 thick, black; hind wing whitish orange, veins yellowish orange. Leg. Prothoracic legs black with some yellow spots on joints; mesothoracic legs with some black dots on tibia; metathoracic legs yellow. Abdomen. Paler yellow than thorax; small tufts in black from 1A-2A. Male genitalia. Cucullar area wide; apex and lobe with small extensions; outer margin flat; sacculus notably wide; tegumen broad; juxta inverted, triangle-shaped; aedeagus 3 ⅓ × longer than wide; vesica 1 ½ × wider than aedeagus, gradually reduced at tip; band with large spines and thick patch of spines near apex.
