Diagnosis.—Cyrtodactylus annulatus is larger than, and readily diagnosable from its phenotypically most similar Philippine congener, C. tautbatorum, by having three ‘‘barbell’’ shaped (vs. 4 or 5 ‘‘bow-tie’’ shaped; Fig. 4) transverse body bands between limb insertions, contact between the first infralabial and two (vs. 3) enlarged postmentals, internasals comprised of single anterior and two posterior scales (versus single internasal), single internasal not contacting supralabials, ventrolateral tubercle row non-protuberant or absent (vs. highly protuberant), and dorsal trunk tubercles conical or sharply pointed (vs. convex and rounded; Table 1). Cyrtodactylus annulatus is smaller than C. agusanensis, and further differs from this species by having a precloacal groove, invariably six precloacal pores (vs. 6–9), and fewer post-cloacal tubercles and midbody dorsal scales. Cyrtodactylus annulatus also lacks femoral pore-bearing scales and pores (present in C. agusanensis; Table 1). It is smaller than C. philippinicus, from which it can further be distinguished by the invariable presence of three (vs. 3–6) transverse bands, fewer precloacal pores, and a reduced or absent (vs. protuberant) ventrolateral tubercle row. Cyrtodactylus annulatus is diagnosed from C. redimiculus by having a precloacal groove, near-consistent dorsal body tuberculation (vs. reduced tuberculation on anterior trunk, nuchal region, and head of C. redimiculus), a reduced or absent (vs. protuberant) ventrolateral tubercle row, and fewer midbody dorsal scales and paravertebral scales. Cyrtodactylus annulatus is further distinguished from C. redimiculus by the absence of a reticulate head color pattern. These and other differences between congeners are summarized in Tables 1 and 2 in WELTON et al. 2009.
|Etymology||Named after the diminutive form (“annul-”) of Latin “anus” = ring.|
