CommentRÖSLER et al. 2007 revalidated Cyrtodactylus agamensis but their diagnosis of this species is fairly vague (differs from other species ”by being smaller in SVL and having more ventrals...” etc.). Their key states “67” ventrals” for agamensis but this seems to be based on a single female.

Abundance: Cyrtodactylus agamensis is known from a single female, the holotype (Rösler et al. 2007, Hartmann et al. 2016, Meiri et al. 2017) and 6 additional specimens found by Milto & Bezman-Moseyko 2021.

Distribution: the IUCN assessment by Iskandar (2021) has it all over Sumatra and western offshore islands.
