The black cap usually covers almost the entire parietal and usually is in contact with the black nuchal band, interrupting the white postparietal band. The chin is white with irregular spots on some shields, particularly around their posterior borders. The nuchal black band begins 1 dorsal behind the parietals and is 4 to 6 dorsals and ventrals long. The remainder of the black bands are 3 to 4 dorsals and 2 to 3 ventrals long. The red bands are as long as or longer than the black bands, with irregular black tips on all dorsals. On the venter, the red scales have irregular black spots concentrated around their posterior borders. The white bands are 1 to 1Y2 dorsals long and are irnmaculate. The black tail bands are twiee as long as the white ones.
The males have 20 to 26 (24.2) and the females have 18 to 27 (24.7) black body bands. The black tail bands are 6 to 9 (7.8) in males and 4 to 5 (4.6) in females.
