Zoology. 145. : Red sand desert with dry lake in background right, vicinity of Birthday, South Austraha — near region of greatest sympatry or near-sympatry of species of Nephrurus. Nephrurus laevissimus Mertens, 1958 1924 Nephrurus levis (part) Kinghorn. 14: 166. 1958 Nephrurus laevissimus Mertens. 39: 51; pi. 3 (fig. 4). Type locality: Dünen etwa 2 km NW des Ayers Rock, Northern Territory, Zentral- Australien. Holotype: SMF 53201. Diagnosis: Two ribless cervical vertebrae; phalangeal formulae 2-3-3-3-3 (manus and pes); metatarsals two or more times length of corresponding phalanges; flanks smooth; tail moderate, with 5—7 rows of caudal tubercles and 13—19 caudal annuli. Comments: Mertens' (1958) description is adequate. Nephrurus laevissimus occurs in sandridge regions throughout the arid zone (Fig. 61) and is in sympatry with N. asper in the southern Northern Territory, with N. levis across northern South Australia, with A^. vertebralis in eastern Western Australia and with N. stellatus in a narrow band across the Nularbor Plain. It reaches a maximum SVL of 87 mm (Dclean & Harvey 1981). Pianka & Pianka (1976) and Delean & Harvey (1981), in Western and South Australia respectively, found N. laevissimus in association with Triodia dominated sandridges where populations may be locally very dense. It feeds primarily on spiders, coleopterans.
