SK16 1042, SK16 1074, SK16 1075, SK16 1094) Distribution: AB (B), KA (B, R ), KF ( R ), LO (B) Remarks: This species occurs in dry savannas and semi-deserts in lower elevations ( Spawls et al. 2018 ). We recorded 25 individuals of this strictly terrestrial agama ( Fig. 4C ) in bushland at all sites except IL. Activity was high during all four study months, and individuals were observed to be active from 0900 h to 2200 h. The average T b was 31.9 ± 3.0 °C (28.4–36.5 °C; N = 5) with T sub ranging from 24–39 °C and T a ranging from 27–36 °C.
