Cordylus macropholis (Boulenger, 1910)
endemic Appendix II Protected LC

Morphological description

Boulenger (1910) described the species as follows: Head shields very rugose; nasals not swollen, in contact, the nostril in its posterior part, close to the first upper labial and the anterior loreal; frontonasal tetragonal; praefrontals forming a suture; interparietal tetragonal, between the two pairs of parietals and touching the frontoparietals; temporals strongly keeled, the posterior forming short spines; lower eyelid scaly; four or five upper labials; five lower labials, bordered by four large, striated, and keeled shields; gular scales large, imbricate, strongly keeled, sharply pointed. Dorsal scales very large, forming regular transverse series, rugose, strongly keeled, denticulate posteriorly, the keels terminating in a short spine, on the flanks similar; 17 transverse series from occiput to base of tail, the largest containing 14 scales ; a distinct lateral fold. Ventral scales smooth, quadrangular, the outer pointed behind, in 10 longitudinal and about 20 transverse series. A pair of enlarged posterior praeanal scales. Limbs with large spinose, serrated scales. 9 femoral pores on each side. Tail with whorls of large, rugose, strongly keeled, spinose, serrated scales, the spines strongest on the sides. Olive-brown above, with large irregular dark brown blotches, pale olive beneath. Measurements: Total length, 130 mm.; from snout to vent, 68; head, 19; forelimb, 25; hindlimb, 32.

Type notes

Type locality: Little Namaqualand, South Africa. Holotype: SAM (South African Museum, Capetown)

Taxonomic notes

There is a large geographic gap between each of the three populations, particularly for the northernmost population. The degree of differentiation between these populations has not been assessed (Tolley et al., 2023).

Global distribution

South Africa

SA distribution

This species occurs as three populations along the west coast of South Africa, from Port Nolloth (Northern Cape province) southwards to Yzerfontein (Western Cape province). There is a 250 km gap between the northern and central populations, and a 50 km gap between the southern and central populations, with the distribution extending up to about 15 km inland for all subpopulations (Tolley et al., 2023).

Movement

These lizards are known to run and hide. When running on four legs, lizards often move their fore feet diagonally in unison—the right fore foot with the left hand and the left fore foot with the right hand. The body's bent is simultaneously reversed. The shoulders, hips, and other joints in the legs as well as the bending of the back all contribute to moving the feet forward. Leg and back muscles work together to power running (Alexander, 2012).

Trophic level

Carnivore - Invertivore (invertebrate-eating)

Trophic strategy

These lizards feed mostly on beetles (Branch, 1998).

Reproduction

This species is viviparous, producing one or two young in April-May (Branch, 1998).

Behaviour

This is a very shy lizard, scurrying off when in danger (Branch, 1998).

Uses

This information was extracted from Tolley et al. (2023): This species is listed on CITES Appendix II but has not been legally exported from South Africa for the pet trade (UNEP-WCMC, 2020). There were, however, limited exports for scientific purposes (14 individuals since 1988), but this is not expected to pose any risk for the species. Twenty-five individuals are recorded as exported from Mozambique, but the species does not occur there and this likely represents exports of a different cordylid species, or potentially the laundering of individuals through other countries.
