Pamiria omphisa, the dusky green underwing, is a species of blue (Lycaenidae) butterfly found in Asia.

The extent of this colour very variable; in some specimens, on the forewing it spreads irregularly outwards mainly along the costa and on the hindwing in the middle to the disc; in others, it covers the basal three-fourths of the wings, leaving a well-defined broad terminal margin of the ground colour on the forewing, and on the hindwing, broad costal, terminal and dorsal margins; cilia conspicuously white.

Underside of forewing is a clear, slightly brownish grey, paler along the costal and terminal margins; a transverse, slightly lunular discocellular spot and a transverse series of six small discal spots black, all with slender white edgings, the discal series placed in a slight curve, the posterior three spots en echelon; no terminal markings except an anteciliary dark line.

Forewings and hindwings with slender, black, anteciliary lines and conspicuous snow-white cilia.

The butterfly occurs in India (Lahul), northern Pakistan, in the Himalayas (Chitral, Ladakh), and north to China.
