Type locality: Kyauk Nagar Cave, 11 km southwest of Pyin Oo Lwin, Pyin Oo Lwin Township, Pyin Oo Lwin District, Mandalay Region, Myanmar (20.93087°N, 95.22580°E; 715 m in elevation).  
Reproduction 
TypesHolotype. LSUHC 13947, Adult male collected on 24 March 2018 at 1030 hrs Myint Kyaw Thura, Aung Lin, Perry L. Wood, Jr., Aung Lin Htet, and L. Lee Grismer. Paratypes. Adult males LSUHC 13946, and 13948–52 bear the same collection data as the holotype. 
DiagnosisDiagnosis. Cyrtodactylus aunglini sp. nov. differs from all other species of Cyrtodactylus by having the unique combination of the following characters: 8–10 supralabials and infralabials; 36–45 paravertebral tubercles; 21–26 longitudinal rows of body tubercles; well-developed body tubercles not extending past the hemipenial swellings; no gular tubercles; a ventrolateral fold; 41–49 ventral scales; digits not relatively short; basal subdigital lamellae expanded proximal to digital inflection; 19–23 subdigital lamellae on the fourth toe; no enlarged femoral scales or pore-bearing femoral scales; no precloacal groove; 12 or 13 pore-bearing, contiguous, precloacal scales; precloacal scale row not sharply angular; multiple enlarged post-precloacal scales; three or four cloacal spurs in males; caudal scales arranged in poorly defined segments; no enlarged, plate-like, medial subcaudal scales; band on nape; seven or eight dorsal bands lacking paravertebral elements, zig-zag to regular in shape, usually wider than immaculate interspaces, not bearing lightened centers, not edged posteriorly with light-colored tubercles, and posterior borders bold and anterior borders diffuse; clusters of enlarged, light-colored scales usually in ventrolateral fold; top of head generally unicolor; nine or 10 immaculate light caudal bands not encircling tail; nine or 10 dark caudal bands wider than light caudal bands; raised, moderately keeled body tubercles; and a maximum SVL of 81.6 mm (Tables 4, 5). These characters are scored across all species in the gansi group in Table 3 in Grismer et al. 2018: 160.

Comparisons. Cyrtodactylus aunglini sp. nov. is most closely related to C. gansi from which it differs by being larger (maximum SVL = 81.6 mm versus 62.3 mm); having well-developed dorsal tubercles that do not extend beyond the hemipenial swelling; distinctive ventrolateral folds; more ventral scales (41–47 versus 30–36); relatively longer digits; more subdigital lamellae (19–23 versus 10); no precloacal groove; 12 or 13 contiguous, pore-bearing, precloacal scales versus 16–29 contiguous, pore-bearing, precloacal scales; enlarged post precloacal scales; and various aspects of head color pattern (Tables 3, 4, 5). The two are also separated by a 16.9% uncorrected pairwise sequence divergence. From the superficially similar C. mandalayensis, C. aunglini sp. nov. varies by having more longitudinal rows of body tubercles (21–26 versus 18); more ventral scales (41–47 versus 32); more pore-bearing, precloacal scales (12 or 13 versus eight); caudal scales arranged in regular segments; and various aspects of color pattern (Tables 3, 4, 5). Cyrtodactylus aunglini sp. nov. varies from all other species of the gansi group in not having well-developed tubercles that extend beyond the base of the hemipenial swellings; it varies from all other species of the gansi group except C. myaleiktaung sp. nov. in that the top of the head is unicolor as opposed to bearing a dark pattern of varying configurations (Table 3, 4, 5). Table 3 lists combinations of other characters separating C. aunglini sp. nov. from varying combinations of other species of the gansi group. 
Comment 
EtymologyThis species is named to honor Mr. Aung Lin of Fauna & Flora International, Yangon for his extensive participation and assistance during all our expeditions in Myanmar and for his outreach projects to various communities that emphasize habitat conservation through sustainable utilization.
