Etymology.

In honor of my colleague and friend Dr. Deborah Matthews-Lott, who has supported me during my travels in entomology, especially on Lepidoptera trips.

Diagnosis.

Millerana matthewsae is closely related to M. tigrina ; it has brownish orange antenna and can be differentiated by the wide well-defined pattern of foreign lines, and the large orbicular and reniform spots. The most distinctive character of the male genitalia is the costal margin of the valva is strongly curved upward.

Description.

Head. Palp with long black and yellow hair-like scales; frons dark yellow. Thorax. Dark yellow with some black patches on dorsal area; Wing. Forewing length: male 18-20 mm; forewing paler yellow coloration than thorax; antemedial, medial, and subterminal lines complete; postmedial line almost complete except in area between cells of CuA1 and half of CuA2; V-shaped mark at base of CuA2 with upper line longer than lower line; terminal area covered by scattered black scales except in M3 and CuA1 cells; orbicular spot very large, barely touching top and bottom of discal cell; reniform spot with large line marking inside of discal cell; hindwing white with veins and fringe pale yellow. Leg. Prothoracic and mesothoracic legs brownish orange and black with joints yellow; metathoracic legs yellow. Abdomen. Yellow, paler than remainder of body; dorsally with thin black tufts in middle of A1-A6 and with dark yellow tufts at A2-A3. Male genitalia. Cucullus wide and curved upward on costal margin; apex rounded; some protuberances in the outer margin with the upper one the largest and curved downward; sacculus wide and short; upper side of juxta has a shallow concave depression; tegumen narrow laterally; aedeagus narrow, ⅓ × longer than vesica; vesica long rounded basally; Transverse band of spines near middle of vesica.

Immature stages.

Unknown.

Distribution.

This species has been collected only in the western zones of Peru at very high elevations almost 4000 m (Fig. 94 ).

Biology.

Unknown.

Remarks.

The holotype (Fig. 40 ) and the paratype have both hindwings slightly broken. The other specimens were almost destroyed with only the thorax and forewings remaining.
