DiagnosisDiagnosis: Cyrtodactylus zhenkangensis sp. nov. differs from all other congeners by the following combination of characters: medium size (SVL 78.1–87.4 mm); ventrolateral folds present with interspersed tubercles; 12–15 enlarged femoral scales on each thigh; 2–5 femoral pores on each thigh in males, 0–3 pitted scales on each thigh in females; eight or nine precloacal pores in a continuous row or separated by one poreless scale in males, 7–9 pitted scales in females; two or three postcloacal tubercles on each side; 18–21 lamellae under finger IV, 21–23 lamellae under toe IV; subcaudals enlarged, arranged alternately as single and double on anterior and mostly single at middle and posterior; dorsal surface of head with obvious, light-colored reticulations; eight or nine irregular transverse bands on the dorsum of body (Liu and Rao 2021).

Comparisons: Cyrtodactylus zhenkangensis sp. nov. is distinguishable from all other members of the C. wayakonei group by a unique combination of morphological characters. Cyrtodactylus zhenkangensis sp. nov. differs from C. bichnganae Ngo & Grismer, 2010; C. huongsonensis Luu, Nguyen, Do & Ziegler, 2011; and C. sonlaensis Nguyen, Pham, Ziegler, Ngo & Le, 2017 in having fewer femoral pores in males (4–10 vs 15–29). Cyrtodactylus zhenkangensis sp. nov. differs from C. bobrovi Nguyen, Le, Pham, Ngo, Hoang, Pham & Ziegler, 2015; C. otai Nguyen, Le, Pham, Ngo, Hoang, Pham & Ziegler, 2015; and C. vilaphongi Schneider, Nguyen, Le, Nophaseud, Bonkowski & Ziegler, 2014 in having enlarged subcaudal scales (vs lacking enlarged subcaudals). Cyrtodactylus zhenkangensis sp. nov. differs from C. chauquangensis Hoang, Orlov, Ananjeva, Johns, Hoang & Dau, 2007; C. cucphuongensis Ngo & Chan, 2011; C. houaphanensis Schneider, Luu, Sitthivong, Teynié, Le, Nguyen & Ziegler, 2020; C. puhuensis Nguyen, Yang, Le, Nguyen, Orlov, Hoang, Nguyen, Jin, Rao, Hoang, Che, Murphy & Zhang, 2014; C. spelaeus Nazarov, Poyarkov, Orlov, Nguyen, Milto, Martynov, Konstantinov & Chulisov, 2014; and C. taybacensis Pham, Le, Ngo, Ziegler & Nguyen, 2019 in having femoral pores in males (vs lacking femoral pores in males). Cyrtodactylus zhenkangensis sp. nov. differs from C. martini in having femoral pores in males (vs lacking femoral pores in males) and more irregular transverse bands on the dorsum of body (8–9 vs 5–7). Cyrtodactylus zhenkangensis sp. nov. differs from C. ngoiensis Schneider, Luu, Sitthivong, Teynié, Le, Nguyen & Ziegler, 2020 and C. soni Le, Nguyen, Le & Ziegler, 2016 in its smaller body size (64.1–87.4 mm vs 62.9–103 mm) and having more lamellae under finger IV (18–21 vs 15–19) and toe IV (21–23 vs 18–22). Cyrtodactylus zhenkangensis sp. nov. differs from C. wayakonei in having enlarged subcaudal scales (vs lacking enlarged subcaudals) and with more irregular transverse bands on the dorsum of body (8–9 vs 5–7). For other species which were not included in the phylogenetic analyses and resemble Cyrtodactylus zhenkangensis sp. nov. in morphology. Cyrtodactylus zhenkangensis sp. nov. differs from C. auribalteatus Sumontha, Panitvong & Deein, 2010 in having more transverse bands on the dorsum of body (8–9 vs 4–5), obvious reticulations on the dorsum of head (vs no obvious reticulations) and absent dark-colored nuchal loop (vs present). Cyrtodactylus zhenkangensis sp. nov. differs from C. doisuthep Kunya, Panmongkol, Pauwels, Sumontha, Meewasana, Bunkhwamdi & Dangsri, 2014 in having fewer femoral pores (0–10 vs 12–14), more precloacal pores (7–9 vs 6), and absent dark-colored nuchal loop (vs present). Cyrtodactylus zhenkangensis sp. nov. differs from C. dumnuii Bauer, Kunya, Sumontha, Niyomwan, Pauwels, Chanhome & Kunya, 2010 in having more lamellae under toe IV (21–23 vs 19), absent dark-colored nuchal loop (vs present), and obvious reticulations on the dorsum of head (vs not obvious or no reticulations). Cyrtodactylus zhenkangensis sp. nov. differs from C. erythrops Bauer, Kunya, Sumontha, Niyomwan, Panitvong, Pauwels, Chanhome & Kunya, 2009 in having fewer femoral pores in males (4–10 vs 18–20), more lamellae under finger IV (18–21 vs 16) and toe IV (21–23 vs 20), and more transverse bands on the dorsum of body (8–9 vs 6–7). (Liu and Rao 2021).

Color in life: Head brown with pale-yellow, slightly symmetrical reticulations on either side of the midline, no dark-colored nuchal loop; dorsum of body brown with approximately nine pale-yellow, transverse, irregular bands from forelimb insertions to base of tail and one longitudinal, continuous, narrow vertebral stripe; dorsal surface of limbs brown with some light-yellow, irregularly shaped bands, some small, light-yellow spots on the dorsum of fingers and toes; ventral surface of head, body, and limbs grey with no stripes or spots; tail brownish black with ten yellowish white rings; iris copper-yellow. (Liu and Rao 2021).
