in 2005 Tokar revised Eryx and eliminated rufescens and loveridgei, leaving only colubrinus. The original 1.1 rufescens were imported into the U.S. from Ethiopia in 2000 as Gongylophis colubrinus. Most breeders working with them feel there are enough differences for rufescens to be at least a subspecies. thanks, scott erycine1@aol.com
