A look at the

Subfamily GEKKONINAE - "True" Geckos

Family GEKKONIDAE



Genus PACHYDACTYLUS - Thick-Toed or Rough Geckos

A large (about 35 species) and rather ancient African genus, being considered ancestral to some of the other gekkonid genera such as Tarentola (Branch). Members of this genus are rarely seen in the trade, partly because there is a perceived lack of interest in "brown geckos" (as Walls calls them), but mainly because South Africa and Namibia do not allow exports. Only one species, P. turneri (Turner's Gecko) occurs with any regularity in captivity. This gecko was formerly confused with P. bibronii, Bibron's Gecko: any references seen in hobbyist literature to "Bibron's Gecko" probably apply to Turner's Gecko instead. Both species are quite similar and both make good pets.

The genus is characterised by the following: dilated toe tips, usually with undivided scansors: no femoral pores, but preanal pores may be present. Body scales small, granular and non-overlapping, with scattered, large keeled tubercles. Most if not all are nocturnal. They live in a diverse range of habitats and feed mainly on arthropods. The range of this genus is centred on southern Africa, with some reaching East Africa, the northernmost limit of their distribution.

In the table below, measurements are total-length approximations. They are taken mainly from the snout-vent length (SVL) given in Branch, and doubled, since the tail length of Pachydactylus species is about 50% of the total length (see SHDA). We have used centimetres rather than inches for this table due to the small size of most of the species.

There is still much work to be done on the individual species on this table, which will be carried out over a period of time.

Scientific Name Common Name Distribution Size Notes
P. affinis Transvaal Thick-Toed Gecko RSA (four northernmost provinces): poss. Free State & SE Botswana 6-9cm B I 
P. amoenus   RSA (Cape Province, Namaqualand)  For some reason this species is not mentioned in Branch. See the EMBL database listing. B I  
P. austeni Austen's Thick-Toed Gecko RSA (coastal areas of W Cape to Little Namaqualand) 6-9cm B I  
P. barnardi   RSA (S Little Namaqualand, Cape Province), Namibia    Formerly considered subspecies of P. rugosus. B I  
P. bicolor Velvety Thick-Toed Gecko Namibia (NW Damaraland and Kaokoveld) 6-8cm B I  
P. bibronii

Bibron's Gecko S. Africa, Angola, S. Tanzania 8-9" Aggressive colonial species, usually found among rocks. Colouring is varying shades of brown, but Bibron's Geckos are distinguishable by five darker brown stripes across the back that are outlined with white spots. The skin is covered with many tubercular scales. This species requires warm dry conditions, in which it will thrive. Despite their colonial habits in the wild (up to 20 have been found in one shelter), cannibalism is not unknown in these lizards and males are aggressive, so they are best kept individually or at most on male and one female, if both are of similar size. Prey consists of insects of various sizes up to the grasshopper: Bibrons are also not hesistant about biting their keeper. Breeding is rare but is a worthwhile goal in view of the restrictions on wildlife exports from this region. Bill Branch commends these lizards as excellent pets. B I

P. laevigatus   RSA, Namibia, Angola  For some reason this species is not mentioned in Branch in the 1998 edition, but is cited from Branch in the EMBL database listing. B I 
P. l. laevigatus
P. l. fitzsimonsi
P. l. pulitzerae
P. maculatus Spotted Thick-Toed Gecko SE Africa [[RSA (Cape Province, S. Zululand, Natal, Transkei, SE Transvall), Swaziland] 4-5" A grey-brown gecko with dark, sharply outlined spots. It lives among stones and bush roots, in leaf litter or in holes in ground, in the latter case often sharing these with girdle-tailed lizards (Cordylid species) or scorpions. Perhaps as a result of this, many in the wild seem to have regenerated tails. Although rarely seen in the trade, in captivity it apparently tames readily. B I

P. m. latirostris RSA (C & N Karoo to Great Namaqualand): Namibia (Spitzkoppe and SW of Brandberg)   Scalation: nasorostrals separated by granular scales: dorsal scales flattened and slightly overlapping. Namibian population is isolated. B I

P. rugosus Rough Thick-Toed Gecko RSA [S. Little Namaqualand, Cape Province], Namibia 9-13cm Until recently this lizard was known as Pachydactylus formosus (click here for reference). Very occasionally seen. Branch notes that all three subspecies may be full species. Preferred habitat is dry riverbeds and/or rocky outcrops, where they may either conceal themselves in cracks or in leaf litter, etc. B I
