Paratype
VIETNAM • 1 ♀; same collection data as for holotype; Field No. BT2017.2; sequence with GenBank accession number MT576020; IEBR 4582. 
DiagnosisDiagnosis: The new species can be distinguished from other members of the genus Cyrtodactylus by a combination of the following characters (Table 1): relatively small body size (SVL up to 68.5 mm); a continuous neckband; 5 or 6 irregular transverse dorsal bands; 11 or 12 bands on original tail; keeled tubercles present on dorsum, posterior limbs and tail; 17 or 18 irregular dorsal tubercle rows; 30 or 31 ventral scale rows; ventrolateral skin folds indistinct; an angular series of seven precloacal pores in male and six pitted, enlarged precloacal scales in female, each series separated by a diastema of undifferentiated scales from 4–6 enlarged, poreless femoral scales; median subcaudals slightly enlarged; 17–20 subdigital lamellae under the fourth toe.

Comparison: We compared the new species with its 19 congeners from the Cyrtodactylus irregularis complex based on an examination of specimens (Table 2) and data obtained from the literature (Smith 1921a, 1921b; Ziegler et al. 2002, 2013; Heidrich et al. 2007; Orlov et al. 2007; Nazarov et al. 2008. 2012; Ngo & Bauer 2008; Rösler et al. 2008; Geissler et al. 2009; Ngo & Chan 2010; Ngo 2013; Nguyen et al. 2013; Schneider et al. 2014; Luu et al. 2017; Pauwels et al. 2018; Neang et al. 2020; Ostrowski et al. 2020). The new species can be distinguished from all other Cyrtodactylus species from Vietnam by morphological characteristics (see Table 3).
In comparison with the species from the C. irregularis complex Cyrtodactylus chungi sp. nov. is distinguished from C. caovansungi Orlov, Nguyen, Nazarov, Ananjeva & Nguyen, 2007, C. kingsadai Ziegler, Phung, Le & Nguyen, 2013, C. takouensis Ngo & Bauer, 2008 and C. yangbayensis Ngo & Chan, 2010 by the absence of transversely enlarged subcaudals.
The new species can be distinguished from C. cryptus Heidrich, Rösler, Vu, Böhme & Ziegler, 2007, C. gialaiensis Luu, Tran, Nguyen, Le & Ziegler, 2017, C. pseudoquadrivirgatus Rösler, Nguyen, Vu, Ngo & Ziegler 2008 and C. taynguyenensis Nguyen, Le, Tran, Orlov, Lathrop Macculoch, Le, Jin, Nguyen, Nguyen, Hoang, Che, Murphy & Zhang, 2013 by the presence of enlarged femoral scales.
The new species can be distinguished from C. bidoupimontis Nazarov, Poyarkov, Orlov, Phung, Nguyen, Hoang & Ziegler, 2012 by its smaller size (SVL of 66.6–68.5 vs 74.0–86.3 mm), fewer ventral scale rows (30–31 vs 38–43) and enlarged femoral scales (4–6 vs 8–10), more precloacal pores in the male (7 vs 4–6), the presence of 6 pitted precloacal scales in the female (vs absence) and by the different dorsal color patter (irregular transversal bands vs irregular transversal bands with light borders).
Cyrtodactylus chungi sp. nov. differs from C. bugiamapensis Nazarov, Poyarkov, Orlov, Phung, Nguyen, Hoang & Ziegler, 2012 by having fewer ventral scale rows (30–31 vs 36–46) and enlarged femoral scales (4–6 vs 6–8), and by the different dorsal color pattern (irregular transversal bands vs round spots forming irregular transverse bands).
Cyrtodactylus chungi sp. nov. differs from C. cucdongensis Schneider, Phung, Le, Nguyen & Ziegler, 2014 by its larger size (SVL 66.6–68.5 vs 55.8–65.9 mm), fewer ventral scale rows (30–31 vs 35–44) and enlarged femoral scales (4–6 vs 5–9).
Cyrtodactylus chungi sp. nov. differs from C. dati Ngo, 2013 by having fewer ventral scale rows (30–31 vs 42–48) and by the different dorsal color pattern (irregular transverse bands vs irregular dark blotches).
Cyrtodactylus chungi sp. nov. differs from C. huynhi Ngo & Bauer, 2008 by having fewer ventral scale rows (30–31 vs 43–46) and by the absence of femoral pores (vs 3–8).
Cyrtodactylus chungi sp. nov. differs from C. irregularis (Smith, 1921) by its smaller size (SVL of 66.6–68.5 vs 72.0–86.0 mm), having fewer ventral scale rows (30–31 vs 38–45) and enlarged femoral scales (4–6 vs 7–8), and by the different dorsal color pattern (irregular transverse bands vs transverse bands with uneven margins in white binding, some bands can fall into separated spots).
Cyrtodactylus chungi sp. nov. differs from C. phnomchiensis Neang, Henson & Stuart, 2020 by its smaller size (SVL 66.6–68.5 vs 76.1–80.7 mm), having fewer ventral scale rows (30–31 vs 45–54) enlarged femoral scales (4–6 vs 0–8), precloacal pores in males (7 vs 4–5) and subdigital lamellae under the fourth to (17–20 vs 20–23) and by the different dorsal color pattern (irregular transverse brown bands vs dark brown body bands bordered by yellowish white or light brown bands).
Cyrtodactylus chungi sp. nov. differs from C. phumyensis Ostrowski, Do, Lee, Ngo, Pham, Nguyen, Nguyen & Ziegler, 2020 by having fewer ventral scale rows (30–31 vs 33–40), the absence of pitted precloacal scales in the male (absent vs 1), more paravertebral tubercles (24–27 vs 20–23) and by the different dorsal color pattern (irregular transverse bands vs anteriorly irregularly spotted and posteriorly banded).
Cyrtodactylus chungi sp. nov. differs from C. phuocbinhensis Nguyen, Le, Tran, Orlov, Lathrop Macculoch, Le, Jin, Nguyen, Nguyen, Hoang, Che, Murphy & Zhang, 2013 by its larger size (SVL 66.6–68.5 mm vs 46.0–60.4 mm), having fewer ventral scale rows (30–31 vs 43–47), the presence of 6 pitted precloacal scales in the female (vs absence) and the different dorsal color pattern (irregular transversal bands vs stripes).
Cyrtodactylus chungi sp. nov. differs from C. ziegleri Nazarov, Orlov, Nguyen & Ho, 2008 by its smaller size (SVL of 66.6–68.5 vs 84.6–93.0 mm), having fewer ventral scale rows (30–31 vs 33–39) and enlarged femoral scales (4–6 vs 8–10).
Cyrtodactylus chungi sp. nov. is most similar to C. sangi Pauwels, Nazarov, Bobrov & Poyarkov, 2018. However, the new species can be distinguished from C. sangi by its larger size (SVL 66.6–68.5 vs 49.9–56.3 mm), having fewer ventral scale rows (30–31 vs 37) and by the different dorsal color pattern (irregular transversal bands with a closed neck band vs irregular transversal bands and pattern with an interrupted neck band). 
CommentOnly minimal information provided as authors did not provide details upon request. 
EtymologySpecific epithet ‘chungi’ is in honor of Prof. Dr Ngo Dac Chung, College of Education, Hue University, in recognition of his outstanding contributions to training of many herpetologist generations from Hue University. For the common names we suggest Chung’s Bent-toed Gecko (English) and Thạch sùng ngón chứng (Vietnamese).
