Tropiocolotes nubicus Baha El Din 1999

Nocturnal. Active animals encountered at night sitting motionless under low vegetation or among rocks. One animal was found climbing a low wall. Tends to forage under cover and keeps a very low profile, moving with its body touching the ground. Shelters during the day under rocks, refuse paper, and various artefacts. In captivity animals forage by either slow-active searching or sit-and-wait strategies. One female lived 21 months in captivity.

The female buries her clutch of a single egg (7x5.1 mm) in a shallow depression in the ground, which she digs in a sheltered loca­tion. Up to 5 clutches were laid by a captive female in one season.

Makes a call composed of about 10 descending, high-pitched syllables, lasting some 5 seconds. The call is very audible, consider­ing the small size of these animals and can be heard from up to 50 m distance. It is most often heard at dusk, as animals emerge from their daytime shelters.

 

Data Deficient

A small gecko with maximum recorded SVL 30.5 mm. Head and body notably depressed. Head narrow and neck indistinct. Limbs rather short and slender. Tail relatively long and slender. Average tail/SVL ratio = 1.41. Body scales smooth and imbricate. Dorsals and ventrals are of equal size, those on the sides of the body are slightly smaller. There are 49-59 scales around mid-body. Two pairs of post-mental shields of roughly equal size. Subdigital scales tricarinate. Pre-anal pores are present in males and some females. Dorsum sandy pink, translucent, with irregular brown blotches and a few scattered, indistinct, lighter specks. Iris golden brown; rostral, internasal region and palpebral fold yellow. A dark brown line extends from the nostril to a little beyond the shoulder. Supralabials white. Tail yellowish with 18-21 transverse bands, the ones at the anterior half of the tail often indiscernible. All ventral sides are white, except for the tail, which is yellowish.

Upper Egyptian Nile Valley. Luxor, Wadi Abbad and Abu Simbel (east and west of Lake Nasser).The animal Anderson (1898) depicts from Luxor probably represents this species, given its indistinct neck, irregular pattern, and long tail with numerous tail bands (18).

All known specimens have been collected from localities immediately bordering the Nile Valley in southern Egypt, in addition to a single specimen from Assalaya, Sudan. The species almost certainly has a wider distribution in Sudan. Eislet's (1962) 20 specimens of " Tropiocolotes steudneri" from Wadi Haifa, which he described as being of highly variable color, probably included examples of T. nubicus, as well as T. steudneri.

Tropiocolotes nubicus appears to be associated with fluvial habitats. It is known from the transitional zone between the Nile Valley and adjacent deserts. Animals have been typically found on low rocky hills, shallow sandy wadis, and near human habitation not far from mesic habitats. At the type locality it was commonly found in syntopy with T. steudneri, but was not found more than a few kilometers from the Nile Valley's margins. T. steudneri, on the other hand, has a much wider distribution in the desert east and west of the Nile Valley, where it occupies much drier environments. 

Around Lake Nasser the species is abundant and is found in high densities. At the type locality 6 animals were found under a single rock and 10 active animals were collected in an area of about 200 m.

The Steudner's gecko (Tropiocolotes nubicus) is a species of gecko of the genus Tropiocolotes. It is found in Egypt and Sudan. The specific epithet nubicus relates to the type locality, the Nubia Region. 'Steudner' may relate to the German botanist and explorer Hermann Steudner (1832-1863).
