Chalarodon steinkampi is a species of Malagasy terrestrial iguanian lizards. It was recognised as a new species in 2015,[1] which is probably microendemic to a small area in south eastern Madagascar.
The species inhabits areas very similar to its sister species, Chalarodon madagascariensis: semi-arid to arid regions with sandy soil that are mostly open.
This species is currently only known from two locations: a locality 30 km north of Amboasary, and Esomony.[1]
Calarodon steinkampi is a cryptic species. It is easiest distinguished from C. madagascariensis by its unkeeled gular and ventral scales, which are keeled in the latter species.[1] Other subtle differences include the mental scale being in contact with four postmentals (rather than 5–8), slightly shorter limbs, and fewer spines in its dorsal crest.[1]
The Madagascar sand lizards are insectivores. In addition to insects, sometimes plants are ingested, particularly in the form of leaves and roots.
