A New Lizard of the Genus 'Callisaurus' from Sonora
Dogert CM and Dorson E. 1942. A New Lizard of the Genus 'Callisaurus' from Sonora. Copeia. 1942(3):173-175
During 1941, Mr. John W. Hilton secured a collection of reptiles and amphibians in southern Sonora which has been deposited in the American Museum. Preliminary investigations disclose an undescribed subspecies of Callisaurus draconoides represented by nine specimens. The race differs from Callisaurus draconoides inusitatus of central coastal Sonora in several characters, most conspicous of which is a relatively shorter foot. The new race, therefore, may be known as:Callisaurus draconoides brevipes, new subspecies. A moderately large Callisaurus most closely related to inusitatus, as indicated by the confluent lateroventral black spots, but differing from that form in having relatively shorter, with fewer lamellae under the fourth toe. Furthermore, it differs from inusitatus in having fewer ventral scales between the gular fold and the vent, fewer femoral pores, and a distinctly darker coloration with an obsolescent middorsal pattern.
