Juvenile QCAZ 6200 (Fig. 1F): Color pattern is similar to adult female QCAZ 10129, but differs in having dewlap skin orange-red with white scales and tongue orange.
Male of
An adult female (SVL 89.1 mm, QCAZ 6045) collected on 1 August 2002 and held in captivity until 27 September 2002 laid an egg (18.5 x 8.4 mm; 682.1 mm3) on 24 August 2002. A juvenile (FHGO 1730) was collected on 25 March 1998 (37.0 mm SVL, 82.5 mm tail length); a larger juvenile (QCAZ 6200) was collected on 1 August 2002 (43.5 mm SVL, 96.0 mm tail length).
