We discuss the provenance, history, and literature pertaining to the poorly known lizard Coloptychon rhombifer (Anguidae: Gerrhonotinae). We include English translations of both the original description of this species by Peters (1876) and the first extensive re-description by Bocourt (1878) from the German and French, respectively. We report on six recently discovered individuals, increasing the total number known to 13. We also discuss habitat and distribution, ontogenetic variation in color and pattern, and provide pertinent observations of captive behavior.
