The Trans-pecos Copperhead is light tan with brown wide cross bands. The band color varies from red-brown to gray-brown depending on locality. It is similar to A. contortrix laticinctus, the Broad-banded Copperhead. The main difference is that the Trans-Pecos Copperhead usually has a black and white patterned underside, while the Broad-banded usually has a plain white or lightly patterned underside. It does not have hourglass shaped bands like other subspecies of Copperheads. Young snakes have a bright greenish-yellow tail tip.
