Distribution

The species is found in the west[2] and north[3] of Ecuador (Paramba[2] of Imbabura Province) and central Peru at altitudes up to 1,630 m.[3]

Description

Wings

Male M. albimacula specimens have wings of a greyish brown colour. The forewing has a dark and hardly excavated apex. The costa, the leading edge of the wing is pale in color. There is a prominent white patch at the distal end of the cell with a minute white blip towards the costa.[3]
The length of the forewing is 19–20 mm.[3]

Genitalia

Following are the characteristics of the genitalia:[3]

  • Gnathos is broad and denticulate, with medial tongue-shaped lobe which is very short, weakly sclerotized and not down curved.
  • Valva is subtriangular.

Antenna

The antenna is not bipectinate.[3]

Diagnosis

The wing colour is most similar to that of M. subornata but the discrete costal marking of that species is absent from M. albimacula. The genitalia are very similar to those of M. leucophasiata and M. amaculata although the shape of the valva differs, but the differences in wing markings of the species are pronounced.[3]
