Female Khwarg’s eyelash-pitvipers can reach lengths of 610 mm (24 in), while males are shorter, reaching a maximum length of 219 mm (8.6 in).

There are 7–14 interoculolabial scales, 3–4 canthal scales, some of which have raised triangular projections, and the loreal scale touches the preocular scale in approximately one-third of specimens. There are 21–23 dorsal scale rows at mid-body, and 144–153 rows of ventral scales in males and 145–154 rows in females. There is no yellow morph of the species. The dorsal bands are absent, faint, or restricted to top of the dorsum in juveniles, and opposing kidney-shaped dorsal marks are entirely absent in the species. There are no black speckles on the dorsal scales or ventral surfaces, with the ventral surfaces being entirely white in most individuals. The iris is pale green or straw yellow.

One individual was observed at night foraging in a fern one meter above the ground.
