The East African Spiny-tailed Lizard (Cordylus tropidosternum common name: dwarf sungazer), also known as the Tropical Girdled Lizard, is an arboreal or rupicolous (rock-dwelling) lizard found in dry forests of East Africa. They range from the southern coast of Kenya to eastern Zimbabwe and central Mozambique. It is a diurnal. They lay down fat reserves in preparation for the dry season.

Description

Tropical Girdled Lizards are brown above with dark brown and cream spots or thin dark bands. A conspicuous black stripe runs along both sides of the neck from the ear to the shoulders. The lips, throat, and belly are cream. The tail is very spiny. Adults are 160–190 mm in length. Males have slightly wider heads than females (the length of a males’ head is about 1.25 times the width whereas the length of a females head is about 1.33 times the width) and are aggressive toward other males of the same species. Both sexes have femoral pores.

Tropical Girdled Lizards are almost identical to the Limpopo Girdled Lizard (Cordylus jonesii) and the Ukinga Girdled Lizard (Cordylus ukingensis). Limpopo Girdled Lizards have smooth scales on the throat and belly (keeled scales in C. tropidosternum) and its nostril is in the center of the nasal scale (the nostril of C. tropidosternum is positioned in the lower posterior corner of the nasal scale). The Ukinga Girdled Lizard has distinctive white lips, a small ridge over each eye (supraocular ridge) and the loreal scale is fused with the preocular scale (separate in C. tropidosternum and C. jonesii).

The Tropical Girdled Lizard is exported from Tanzania and Mozambique for the pet trade where it is commonly referred to as the “Armadillo Lizard” or “Forest Armadillo Lizard or “Jone's Armadillo Lizard.” Tropical Girdled Lizards are not flattened like the true Armadillo Lizard (Cordylus cataphractus) and do not grasp their tail and roll into a ball for defense. With gentle handling and plenty of hiding places, Tropical Girdled Lizards become excellent, long-lived pets and can be trained to accept food from their owner’s hand.
