CommentSynonymy: Stenocercus torquatus BOULENGER 1885 has been removed from the synonymy of S. crassicaudatus by TORRES-CARVAJAL et al. 2005.

Belongs to the clades Scelotrema and Microphractus (fide TORRES-CARVAJAL 2006).

Distribution: FRITTS (1974) reports C. crassicaudatus from Bolivia (Cochabamba Province) but TORRES-CARVAJAL et al. 2005 assume that this possibly represented an undescribed species. Probably also in Bolivia (fide LANGSTROTH 2005) 
EtymologyNamed after its thick tail (Latin crassus, -a = thick, dense, and Latin “cauda = tail).
