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.

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. 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. Description: agrees in size, proportions, and scutellation with P. geitje, except that the granules of the back are intermixed with scattered larger tubercles, twice or three times the size of the granules, that there are a few conical tubercles on the outer side of the tibia, and that there is one lamella less under the disks of the digits. Coloration: greyish or brownish above ; a broad dark brown streak on the side of the head, passing through the eye, converging towards its fellow on the occiput; back with four longitudinal series of large dark brown spots, those of the outer series generally, those of the inner series constantly confluent into a band; tail spotted and variegated with dark brown ; lower surfaces dotted with brown. [SOURCE: Boulenger, Branch] B I 

P. mariquensis

Marico Thick-Toed Gecko

RSA, Namibia

8-11cm

Description: head very convex ; snout very short, hardly as long as the diameter of the orbit, round. Ear-opening oval or subcircular. Body not much depressed. Limbs long; digits rather short, the end slightly dilated, with three lamellae inferiorly; the outer toe inserted a good deal below the fourth. Tail: cylindrical, tapering, without annuli. Scalation details: upper surface of head, body, and limbs covered with granules of subequal size; naso-rostrals generally in contact; rostral broader than high; 7-8 upper labials; 6-7 lower labials, gradually decreasing in size, the anterior as long as, and broader than, the mental, which is very slightly narrowed posteriorly. Abdominal scales equal. Caudal scales equal, smooth, slightly imbricated, much larger than the granules of the back, Male with a series of four conical scales on each side of the base of the tail. Coloration: grey above, with reddish-brown blackish-margined markings ; these markings are a spot on the nose, another on the forehead, a semicircular broad bar surrounding the back of the head, stretching from eye to eye, and posteriorly directed angular broad bars on the back and tail; lower surfaces whitish, immaculate.

Limbs moderate; digits short, of subequal width throughout their length, with 4-5 lamella; inferiorly. Body not much depressed. Tail: rounded, very thick in its anterior half, ending in a thin point. Scalation details: snout covered with convex scales which are much larger than the granules of the back; the remainder of the head covered with very small granules intermixed with larger ones; naso-rostrals in contact; rostral broader than high; 8 upper labials; 7 lower labials, first as long as, and broader than, the mental; latter a little narrowed posteriorly, twice as long as broad.
