We describe a new species of the genus Scincella Mittleman, 1950 from northwestern Vietnam, based on a new collection of ground skinks from Mount Fansipan of the Hoang Lien Son Range in Lao Cai Province. Scincella fansipanensis sp. nov. is distinguished from other Scincella species in the Indochina region and southern China by body size (SVL), separation of prefrontals, number of midbody scale rows, paravertebral scale rows, nuchals and subdigital lamellae on toe IV, separation of toe from finger when limbs are adpressed along the body, and dorsal color pattern. The new species is further distinguished from its congeners by uncorrected genetic distances of 14.60-21.41% (COI gene). The new species is currently known only from high elevation areas of Mt. Fansipan in Vietnam.
