The dark blotches disposed more or less symmetrically on the dorsum vary in size and number, sometimes covering more than half the dorsum. Their colors vary from olive-brown, with some green iridescence, to black. One or several blotches of the same color, sometimes fused into a large irregular shape, were present on the anterior part of the flank in all examined specimens. The vertebral stripe, when present, may be thin, medium or wide and cream, light brown or bright green. Some individuals lack any vertebral stripe.
