Diagnosis | Diagnosis. The new species can be distinguished from other members of the genus Cyrtodactylus by a combination of the following characters: size small (SVL up to 66.8 mm); two internasals; dorsal tubercle rows 18 or 19 at midbody; ventral scale rows 33–41; ventrolateral folds slightly developed; each thigh with 5–7 enlarged femoral scales; femoral pores absent in males and female; a series of 5–7 precloacal pores plus a pitted, enlarged precloacal scale in males; 6 pitted, enlarged precloacal scales in female; paravertebral tubercles 20–23; lamellae under toe IV 18–21; subcaudal scales small, not transversely enlarged; two irregular dark longitudinal stripes in the shoulder region. Sexual dimorphism and variation. The female differs from male specimens in the absence of hemipenial swellings at the tail base. The males have 5–7 precloacal pores (versus 6 pitted scales in the female), which is absent in the female. For morphological variation see Table 1, and for color pattern variation see Figs. 2–7. Paratype ZFMK 103153 has a neckband which is interrupted on the right side. The complete, original tail is longer than snout-vent length and bears 13 transverse bands, which converge ventrally only on the distal half of the tail. The paratype IEBR 4578 has light brownish dorsum with 5 transverse bands. Paratype IEBR 4579 has a continuous neckband and three dorsal transverse bands and the longitudinal stripes at the shoulder region are separated from the postocular stripes. Comparisons. We compared the new species with its congeners based on examination of specimens and data obtained from the literature (Ziegler et al. 2002; Nguyen et al. 2006; Heidrich et al. 2007; Orlov et al. 2007; Nazarov et al. 2008; Ngo 2008; Ngo et al. 2008; Ngo & Bauer 2008; Rösler et al. 2008; Ngo et al. 2010; Ngo & Chan 2010; Ngo & Grismer 2010; Ziegler et al. 2010; Luu et al. 2011; Ngo & Chan 2011; Nazarov et al. 2012; Ngo & Grismer 2012; Ngo 2013; Ziegler et al. 2013; Phung et al. 2014; Nguyen et al. 2013, 2014, 2015, 2017a, b; Grismer et al. 2015; Le et. al. 2016; Grismer et al. 2017; Luu et al. 2017; Ngo et al. 2017; Nguyen et al. 2017; Pauwels et al. 2018; Murdoch et al. 2019; Pham et al. 2019).

Cyrtodactylus phumyensis sp. nov. differs from C. cattienensis Geissler, Nazarov, Orlov, Böhme, Phung, Nguyen & Ziegler by the presence of one pitted, enlarged precloacal scale in males (versus absent), the presence of pitted precloacal scales in female (6 versus absent) and by the different dorsal color pattern (striped neck, dorsum anteriorly irregularly spotted and posteriorly banded versus irregular dark brown transverse bands). Cyrtodactylus phumyensis sp. nov. differs from C. dati Ngo by its lower number of ventral scale rows (33–40 versus 42–48), the presence of one pitted, enlarged precloacal scale in males (versus absent) and by the different dorsal color pattern (striped neck, dorsum anteriorly irregularly spotted and posteriorly banded versus irregular dark blotched). Cyrtodactylus phumyensis sp. nov. differs from C. irregularis (Smith) by its smaller size (SVL of 63.5–66.8 versus 72.0–86.0 mm), the lower number of enlarged femoral scales (5–7 versus 7–8), the presence of one pitted, enlarged precloacal scale in males (versus absent) and by the different dorsal color pattern (striped neck, dorsum anteriorly irregularly spotted and posteriorly banded versus transverse bands with uneven margins in white binding, some bands can fall into separated spots). Cyrtodactylus phumyensis sp. nov. differs from C. martini Ngo by its smaller size (SVL of 63.5–66.8 versus 64.4–96.2 mm), the smaller number of enlarged femoral scales (5–7 versus 14–18), the higher number of precloacal pores in males (5–7 versus 4), the presence of one pitted, enlarged precloacal scale in males (versus absent), the presence of pitted precloacal scales in female (6 pitted versus absent) and by the different dorsal color pattern (striped neck, dorsum anteriorly irregularly spotted and posteriorly banded versus irregular bands). Cyrtodactylus phumyensis sp. nov. differs from C. phuocbinhensis Nguyen, Le, Tran, Orlov, Lathrop, Macculoch, Le, Jin, Nguyen, Nguyen, Hoang, Che, Murphy & Zhang by its bigger size (SVL of 63.5–66.8 versus 46.0–60.4 mm), the lower number of ventral scale rows (33–40 versus 43–47), the presence of one pitted, enlarged precloacal scale in males (versus absence), the presence of pitted, enlarged precloacal scales in female (6 pitted versus absent), and by the different dorsal color pattern (striped neck, dorsum anteriorly irregularly spotted and posteriorly banded versus stripes). Cyrtodactylus phumyensis sp. nov. differs from C. sangi Pauwels, Nazarov, Bobrovi & Poyarkov by its bigger size (SVL of 63.5–66.8 versus 49.9–56.3 mm), the presence of one pitted, enlarged precloacal scale in males (versus absent) and by the different dorsal color pattern (striped neck, dorsum anteriorly irregularly spotted and posteriorly banded versus irregular bands and pattern). Cyrtodactylus phumyensis sp. nov. differs from C. yangbayensis Ngo & Chan by its smaller size (SVL of 63.5–66.8 versus 78.5–92.3 mm), the presence of one pitted, enlarged precloacal scale in males (versus absent), the higher number of sub-digital lamellae under the fourth toe (18–21 versus 15–17) and by the different dorsal color pattern (striped neck, dorsum anteriorly irregularly spotted and posteriorly banded versus irregular rows of narrow, dark brown bands) and from C. ziegleri Nazarov, Orlov, Nguyen & Ho by its smaller size (SVL of 63.5–66.8 versus 84.6–93.0 mm), the lower number of enlarged femoral scales (5–7 versus 8–10), the presence of one pitted, enlarged precloacal scale in males (versus absent) and by the different dorsal color pattern (striped neck, dorsum anteriorly irregularly spotted and posteriorly banded versus dark brown transverse irregular bands). Morphologically, Cyrtodactylus phumyensis sp. nov. resembles C. cucdongensis Schneider, Phung, Le, Nguyen & Ziegler. However, the new species can be distinguished from the latter by the presence of one pitted, enlarged precloacal scale in males (versus absent), the number of internasals (2 versus 1), the higher number of transverse tail bands (13 versus 7) and by the different dorsal color pattern (striped neck, anteriorly dorsum irregularly spotted and posteriorly banded versus irregular transverse bands, two of which consist of spots). |
