Abstract

We observed the mating behavior of Carlia jarnoldae during austral summer (January-March 1999) in Townsville, Queensland, Australia (19°19'S, 146°45'E). Carlia jarnoldae are relatively small (mean snout-vent length 40 mm), terrestrial, diurnal lizards (Cogger 2000). Adults are sexually dimorphic: males are heavier (2.4 g vs. 1.9 g), but not longer (adult males average 44 mm SVL, 68 mm tail length; females average 43 mm SVL, 64 mm tail length), and males are more colorful than are females (Cogger 2000). Breeding males have an orange-brown dorsum with 4-6 narrow black stripes, a black dorsolateral field scattered with small blue spots, and a reddish-orange lateral stripe. The labial scales and throat of males are pale greenish-blue. Females are brown above with scattered black and white flecks tending to form longitudinal lines, and a bright white lateral stripe bordered above and below by black stripes.
