In this section, coloration refers to preserved individuals. In the type series, adult males (24.0-27.0 mm) (n = 2) are smaller than the single known female (SVL = 29.8 mm) (n = 1). See Table 2 for measurements and proportions of the type specimens and see Figure 7 for photographs of preserved individuals. The single adult male paratype (QCAZ 46227) differs from the holotype in having less conspicuous

Three juvenile specimens (QCAZ 46217, SVL 19.3 mm; QCAZ 46141, SVL 12.5 mm and QCAZ 46142, SVL 10.7 mm) are identical in coloration to the holotype but lack well defined dorsal marks. The juvenile QCAZ 46142 has a dark brown venter.
