Type material.

Holotype ♂, Ecuador: Ecuador, Azuay Prov., Cajas Nat.Park, Road Cuenca-Pto Inca, 2°46'50"S, 79°10'58"W, 28.11.2012, H = 3615m, Exped. Ron Brechlin & Victor Sinyaev / UF, FLMNH, MGCL 1049111. [DNA voucher MGCL-NOC-65294] deposited in MGCL. Paratype (1 ♂, MGCL): Ecuador: Same collecting data as holotype.

Etymology.

The only two specimens found in El Cajas National Park, Ecuador, are known.

Diagnosis.

Millerana cajas is similar to M. austini . The best way to identify M. cajas externally is to examine the medial and postmedial lines, which are fused on the forewing. Moreover, the genitalia are very distinctive. The valva is enlarged, especially in the costal region; Millerana cajas has a wide apical protuberance on the valve, similar to that of M. matthewsae ; the vesica has a distal diverticulum surrounded by a spine band.

Description.

Head. Palp short, black and yellow, except last segment that is black with some small yellow scales; frons yellow. Thorax. Covered with light lemon-yellow hair-like scales with some black spots. Wing. Light lemon yellow with black and gray pattern; forewing length: male 18-20 mm; forewing antemedial, medial, and subterminal lines well developed; whereas basal, postmedial, and terminal lines defined by small dots; medial line wide; orbicular spot slightly flattened; reniform spot large, incomplete, with lunate marking at base of M1 cell; V-shaped mark at base of CuA2 narrow; medial and postmedial lines fused by black scales between V-shaped mark in CuA2 and fold; hindwing whitish yellow with veins whitish orange. Leg. Prothoracic legs black with fuscous joints; mesothoracic and metathoracic legs yellow with a black spot on tibia; tarsi black. Abdomen. Paler yellow than remainder of body; tuft on middle area on A1-A5; A1-A3 black and A4-A5 yellow. Male genitalia. Cucullus wide, mainly in on costal area; apex with a wide extension followed by some protuberances on outer margin; saccular region wide; tegumen wide; juxta dentate, slightly curved on upper side; aedeagus 3 ½ × longer than wide; opening larger than rest of aedeagus; vesica long with a distal diverticulum, which is surrounded by a band of long spines; medial area with a large patch of minute spines.

Immature stages.

Unknown.

Distribution.

Biology.

Unknown.
