A relatively robust (L/ M = 76) species of Gerrhopilus having the unique combination of head glands dispersed among the rostral, superior nasal, preocular, ocular, and supraocular scales but absent from the frontal, prefrontal, and all supralabials, a rostrate snout with a transverse keel on the ventral margin of the rostral that lies dorsal to the rictus, angle of pre- oral snout in lateral aspect inclined at an approximately 10° angle from the horizontal, distinct pupil in the eye, longitudinal scale rows 26/24/20, transverse scale rows posterior to the rostral 722, supralabial imbrication pattern T-V, subocular scale one, presubocular scale absent, subcaudal scales 25, L/W ratio 55, and an unpigmented rostral followed sequentially by dark-brown head scales and then paler-brown body scales, giving the face a masked appearance. Refer to Table 1 for additional diagnostic qualitative and quantitative features.
