CommentDiagnosis. A very large (127–161 mm) species of Cyrtodactylus having a single row of enlarged subcaudal scales; enlarged dorsal tubercles conical, keeled, ~5–7 times size of adjacent granules (Fig. 2E), in 24–30 rows; lateral tubercles distinct, ~4–7 times size of adjacent granules and larger than scales of lateral skin fold, which contains tubercles; 38–50 midbelly scale rows; precloacal/femoral pores 75–85, in a single continuous row; lamellae under fourth toe 25–32; head rather wide (HW/HL = 0.69–0.84, mean 0.77); four or five dark dorsal bands between head and hindlimb insertion, of more-or-less even width, margined in black, with 5–10 tubercles sagitally through 3rd dark band; dark spots usually present on light dorsal ground color; venter densely speckled with dark brown; mouth and cloacal linings burnt orange; and posterior supralabials dirty white.

Ecology: commonly in primary and secondary rainforest.

Sympatry: syntopically with Gekko vittatus, Nactus acutus Kraus, and two undescribed species of Nactus, and it may occur syntopically with Gehyra
mutilata, G. oceanica, and Lepidodactylus lugubris. 
EtymologyThe trivial epithet is a Latin masculine adjective meaning “strong like an oak” and is in reference to the large size and stout habitus of the species.
