Wahlberg's velvet gecko (Homopholis wahlbergii) is a species of large gecko, a lizard in the family Gekkonidae. The species occurs exclusively in Southern Africa.
Etymology
[edit]The specific name, wahlbergii, is in honour of Swedish naturalist Johan August Wahlberg.[4] The spelling walbergii was corrected to wahlbergii by Smith (1849) in an errata within an addenda slip (unpaginated).
Geographic range
[edit]H. wahlbergii is endemic to Miombo and Mopane bushveld of Botswana, South Africa, Eswatini, Zimbabwe, and Mozambique. The largest part of its range covers Zimbabwe.[citation needed]
Habitat
[edit]H. wahlbergii shelters under tree bark, rocks, empty bird nests, and other places in coastal bush and mesic and arid savannas.[1]
Description
[edit]Wahlberg's velvet gecko is so called because the skin looks and feels like velvet. The back varies from dark grey to soft grey-brown and may be crossed with paler chevrons or crossbars or have mottled paler areas nestled along the centre of its back and spine.[5] Adults may attain a total length (including tail) of 21 cm (8.3 in), but average total length is 14–18 cm (5.5–7.1 in).[citation needed]
Behaviour
[edit]H. wahlbergii is nocturnal; however, it has been observed to occasionally be active during the day.[1] It ventures far from its usual roost only at night, when courtship generally occurs.[citation needed] It is frequently found in baobab trees and in the roofs and walls of traditional mud-huts and other human dwellings.[5]
Diet
[edit]H. wahlbergii is mainly insectivores.[1] Beetles make up the majority of its diet, with butterflies making up the next largest proportion, although it can also consume millipedes.[6]
Breeding
[edit]Males and females of H. wahlbergii exhibit little to no sexual dimorphism.[6] Females reproduce annually once they reach sexual maturity.[6] The female lays pairs of large, hard-shelled eggs that start soft and adhesive. Egg length, 17–19 mm (0.67–0.75 in), is not correlated to maternal length.[6] These eggs are concealed under bark overhangs or in rock crevices.[5]
