Etymology: The specific epithet refers to Nepal.

Distribution: The species is known only from the type locality.

Remarks: This is a very small Medhiama BORDONI, 2002 . It differs from M. schawalleri BORDONI, 2002 from Nepal (Myagdi Khola) by significantly smaller body, coloration, punctation of head and pronotum (punctation of M. shawalleri dense on the head and on sides of a median stripe of the pronotum), shape of parameres and inner sac. It differs also from M. pauper ( SHARP, 1889) from Nepal, North India, China and Japan ( BORDONI, 2002) by darker coloration, punctation and aedeagus with different parameres and inner sac.
