Etymology

The generic name, Uromastyx, is derived from the Ancient Greek words ourá (οὐρά) meaning "tail" and mastiga (μαστίγα) meaning "whip" or "scourge", after the thick-spiked tail characteristic of all Uromastyx species.

The specific name, geyri, is in honor of German zoologist Hans Geyr von Schweppenburg.[2]

Description

U. geyri is a relatively small, slender species for the genus, with an average total length (including tail) of around 34 cm (13 in). This lizard is usually beige or orange with lighter spots. It is one of the brightest-colored species of the genus Uromastyx. There are two phases of U. geyri, the "red" geyri and "yellow" geyri, color being their only difference. The red phase is often nearly solid reddish to neon pumpkin orange, and the yellow phase is in or near a neon-range. Females are a more pale color than the males, showing more tan variations of the coloring and much less belly coloring as well as less vivid patterns, most females having a simple "freckling" on the back. "Saharans" are medium-sized lizards, many averaging 11–14 in (28–36 cm) in total length, and weighing 250 grams (8.8 oz) or more as adults.
