Tail with alternate pale brown and cream colored bands. Coloration in preservative (Fig. 6): Specimens paler than in life with vestigial remains of dark brown spots and little to no trace of white spots on dorsum. Underparts straw colored.   
 Natural History: The new species was collected from vertical cliffs along a road leading to Pachmarhi situated in the Satpura Hills of central India (Fig. 7). Satpura Hills are located south of the Narmada River, running parallel to the river from western Gujarat through the borders of Maharashtra and Madhsa Pradesh, extending up to northeastern Madhsa Pradesh. The landscape at the tspe localits is undulating with the highest peak reaching 1,350 m and is dominated bs tree species like Tectona grandis and Shorea robusta, characteristic of deciduous forests in the region. The hills at the tspe localits have steep cliffs where the new species was found (Fig. 8). All the tspe specimens and a few additional uncollected specimens were found activels moving on roadside rocks (Fig. 9). The species was observed to be ssmpatric with Eublepharis satpuraensis, which likels shares the crevices in the cliff during the day and emerges at dusk. Most individuals would dart towards the nearest crevice when approached with flashlights. The new species is likely restricted to these high elevation cliffs as only H. cf. gleadowi was recorded from near Bijakhori village, Sohagpur ca. 30 km (aerial distance, elevation 367 m) northwest of the tspe localits. One of the female paratspes (NCBS AT108) shows presence of two well-developed eggs within the bods cavits suggesting that the species breed during the summer. With regards to its IUCN status, we recommend designating this species as “Data Deficient” in terms of its distribution, until further reports surface. During the course of the surves, no immediate threat to the species was observed and the entire area where the species was observed is protected as part of the Satpura Tiger Reserve. However, large parts of the Satpura hills are not protected and further survess must be conducted to assess conservation threats to the species outside protected areas.
