A relatively robust (adult L/M = 58) species of Gerrhopilus having the unique combination of a rostrate snout with a transverse keel on the ventral margin of the rostral that extends ventral to the rictus, angle of pre-oral snout in lateral aspect horizontal to the body axis, a vestigial eye lacking a distinct pupil, preocular covering two-thirds of the eye in lateral view, longitudinal scale rows 24/22/20, transverse scale rows posterior to the rostral 627, supralabial imbrication pattern T-V, subocular scale one, presubocular scale absent, prefrontals and supraoculars larger than frontal and parietals and interparietal, subcaudal scales 26, L/W ratio 80, and tail spine oriented ventrally at an angle of 90 ̊ to axis of anteroventral surface of that terminal scale (and, hence, to body axis). Refer to Table 1 for additional diagnostic qualitative and quantitative features. Additional details (1459 characters) are available for collaborators and contributors.
