Preocular elongate, approximately twice as long as high, contacting nasal but not internasal; one postocular; two (92%) or three (8%) posterior temporals; 160–178 ventrals in nine males, 186– 195 in nine females, sexually dimorphic without overlap; 41–53 subcaudals in males, 26–34 in females, sexually dimorphic without overlap; SCR 19.3–23.0% in males, 12.2–14.9% in females, sexually dimorphic without overlap; females with very short tails relative to males (TLR sexually dimorphic without overlap, 16.7–20.8% in adult males, 9.0–11.6% in adult females); pale markings on prefrontals absent, even in juveniles; tail spine brown, same colour as remainder of tail; venter uniformly yellow; juveniles with brown anterior supralabials; and head pattern in juveniles typically consisting of a complete, broad, pale band across the nape, parietals, temporals, and last two supralabials, with remainder of head anterior to that lacking pale markings.” (Kraus et al. 2022)
