Line drawings of Stoliczkia khasiensis (A, B), Stoliczkia vanhnuailianai (C, D) and Paraxenodermus borneensis (E, F) based on ZSIK 14945, BNHS 3656 and BMNH 1946.1.15.58 respectively. Genus characteristics are highlighted in different colours: 1) some supralabials in contact with eye in Stoliczkia, separated by circumorbital scales in Paraxenodermus; 2) fewer supra- and infralabials in Stoliczkia than in Paraxenodermus; 3) single prefrontal in Stoliczkia versus 2–3 in Paraxenodermus, 4) fewer scales between parietal and supralabials immediately behind eye in Stoliczkia than in Paraxenodermus, and 5) small row of scales between frontal and prefrontals absent in Stoliczkia, present in Paraxenodermus. Note small scales behind the temporals are indicative rather than precisely accurate. Pale grey coloured areas are bare skin exposed between scales. Illustrations by V. Deepak and Surya Narayanan. Scale bars = 10 mm.
