Geographic range
editHabitat
editThe preferred natural habitat of T. punctatissimus is desert at altitudes from sea level to 300 m (980 ft).[1]
Description
editA small burrowing skink, T. punctatissimus usually has a snout-to-vent length (SVL) of 6–8 cm (2.4–3.1 in). Maximum recorded SVL is 8.6 cm (3.4 in). It has no eyelids, no external ear openings, and usually no legs. However, some specimens may have rudimentary hind limbs. Dorsally, it is golden brown, with many black dots forming lines. The ventral surface of the tail is silvery blue.[3]
Behavior
editT. punctatissimus is terrestrial and fossorial.[1]
Reproduction
editT. punctatissimus is viviparous.[2]
Subspecies
editThree subspecies are recognized as being valid, including the nominotypical subspecies.[2]
- Typhlacontias punctatissimus bogerti Laurent, 1964
- Typhlacontias punctatissimus brainei Haacke, 1997
- Typhlacontias punctatissimus punctatissimus Bocage, 1873
Etymology
editThe subspecific name, bogerti, is in honor of American herpetologist Charles Mitchill Bogert.[4]
The subspecific name, brainei, is in honor of Steve Braine, who was a ranger at Skeleton Coast National Park, Namibia.[2]
