Description. Snout rounded, prominent. Rostral very broad, truncated posteriorly; frontal subhexagonal; supraocular transverse, its lateral apex between preocular and ocular; eye spot, if visible (mainly in subadult specimens) below preocular; nasal suture arising from first labial; SIP II –P (N 2, N 2 /P, O, O); MSR 22–26, reduction A/B 2 to 6, B/C 0 to 2; MD 406–507; vertebrae 251–271; MD/V ratio 1.63–1.80; L/D ratio 46–95. Dark brown to black above, each scale lighter basally, pale brown to white below. Subadults are lighter in colour.

Size. Largest specimen (NMZB-UM 23667 – Mutare, Zimbabwe) 372 mm in total length.

Habitat. Coastal forest and miombo woodland. NMZB-UM 8029 was taken under a rock at the foot of a granite inselberg. Most of the Mutare specimens were found in urban compost heaps, but the specimen from Pungwe Bridge was in gallery forest.

Distribution. Southern Malawi, northern Mozambique and northeastern Zimbabwe, 600–1415 m ( Fig. 10 View FIGURE 10 ).
