Remarks: Heliobolus spekii (Fig. 4L) is a widespread generalist species inhabiting coastal thicket and woodland, moist and dry savanna, and semi-desert at elevations from sea level to 1,500 m (Spawls et al. 2018). We found 18 individuals throughout the study period. This species was absent from the sites near the lake shore and from sparsely vegetated areas. It was only found further inland at the Karare site, Lomosia, and at TBI in more densely vegetated, grassy bushland and on vegetated riverbanks. One pair was observed mating on 17 April 2017. The average T b was high at 37.5 ± 1.4 °C (34.5–39 °C; N = 8) at substrate temperatures (T sub) ranging from 28–49 °C and T a ranging from 29–34 °C.
