A. hyperythra has five or six light-colored stripes down a black, brown, or grey dorsal side. The middle stripe may be forked at both ends. It is whitish-yellow or cream on the venter, and has an orange throat (females and juveniles may lack this character). Its head is yellow-brown to olive colored, and its tongue is forked and flicked continually. It has a length of 5–7.2 centimetres (2.0–2.8 in).
Juveniles of this species have cobalt blue legs and tails. The entire ventral surface of males, including the tail, may be orange, although gravid females may also have some orange especially lining the lower jaw. The colors are most distinct in the breeding season. Males have larger femoral pores than females.
The orange-throated whiptail has a distinctive, jerking gait.
