Comparisons. We compared Cyrtodactylus muangfuangensis sp. nov. with other congeners from Laos and neighboring countries in the mainland Indochina region, including Vietnam , Cambodia , and Thailand based on examination of specimens (see Appendix) and data from literature ( Luu et al . 2014 ; Nazarov et al . 2014 ; Nguyen et al . 2014 ; Panitvong et al . 2014 ; Pauwels et al . 2014; Pauwels & Sumontha 2014 ; Schneider et al . 2014 a ,b; Luu et al . 2015 ; Nguyen et al. 2015b ; Sumontha et al. 2014 , 2015 ; Pauwels et al . 2016 ; Le et al. 2016 ; Luu et al . 2016 a ,b,c; Luu et al . 2017 ; Nguyen et al . 2017 ; Pauwels et al . 2018 ; Nazarov et al . 2018 ; Murdoch et al . 2019 ; Pham et al . 2019 ). The new species can be differentiated from other known species of the genus Cyrtodactylus by morphological characters (see Table 3 ). Below we compared the new species with the morphologically similar species from Thailand , Vietnam , and remaining species from Laos . FIGURE 2. Dorsal view of the adult male holotype of Cyrtodactylus muangfuangensis sp. nov. (VNUF R.2018.32) in life. Photo: S. Sitthivong FIGURE 3. Cloacal region (precloacal and femoral pores marked with black dots) of the holotype of Cyrtodactylus muangfuangensis sp. nov. in preservative. Photo: V. Q. Luu Cyrtodactylus muangfuangensis sp. nov. is morphologically similar to C. dumnuii Bauer, Kunya, Sumontha, Niyomwan, Pauwels, Chanhome & Kunya ; C. tigroides Bauer, Sumontha & Pauwels , C. khelangensis Pauwels, Sumontha, Panitvong & Varaguttanonda , C. brevipalmatus (Smith) , and C. huongsonensis Luu, Nguyen, Do & Ziegler in arrangement and the number of femoral and precloacal pores. However, the new species can be distinguished from C. dumnuii by having fewer ventral scales (31–37 versus 40), the presence of pitted scaless in females ( versus absent), nuchal band enlarged posteriorly, butterfly-shaped ( versus interrupted posteriorly), fewer body bands (5 versus 6–7), fewer dorsal tubercles at midbody (15–16 versus 18–20), and fewer dark and light caudal bands on tail (8–10 versus 12; 9–10 versus 13, respectively); from C. tigroides by having fewer precloacal pores (6 versus 8 or 9), a heterogeneous mixture of body scalation ( versus homogeneous), more numbers of conical, keeled tubercles (15–16 versus 13 small tubercle rows); from C. khelangensis by its smaller size (maximum SVL 83.9 mm versus 95.3 mm ), having more pitted scales in females (5–9+5–8 versus 2+1 femoral pores in left and right side, respectively), and more precloacal pores in males (6 versus 2–5); from C. brevipalmatus by its larger size (maximum SVL 83.9 mm versus 72 mm ), having fewer ventral scales (31–37 versus 44), having fewer femoral pores in males (6 versus 9), dorsal pattern banded ( versus blotched); from C. huongsonensis by having fewer ventral scales (31–37 versus 48), the presence of pitted scales in females ( versus absent), and fewer pitted scales in females (6 versus 8). For more details see Table 4 . FIGURE 4. Type series of Cyrtodactylus muangfuangensis sp. nov. from right to left: adult male holotype (VNUF R.2018.32); adult female paratype (NUOL R.2018.33); subadult female paratype (ZFMK 102701); subadult female paratype (VNUF R.2018.41); adult female paratype (NUOL R.2018.39). Photo: V. Q. Luu Cyrtodactylus muangfuangensis sp. nov. has transversely enlarged median subcaudal scales and thus differs from the following species which lack this structure: C. buchardi David, Teynié & Ohler , C. cryptus Heidrich, Rösler, Vu, Böhme & Ziegler , C. interdigitalis Ulber , C. pseudoquadrivirgatus Rösler, Vu, Nguyen, Ngo & Ziegler , C. vilaphongi Schneider, Nguyen, Le, Nophaseud, Bonkowski & Ziegler , and C. ziegleri Nazarov, Orlov, Nguyen & Ho. Cyrtodactylus muangfuangensis sp. nov. has femoral pores in the male and thus differs from the following species which lack this structure: C. pageli Schneider, Nguyen, Schmitz, Kingsada, Auer & Ziegler , C. spelaeus Nazarov, Poyarkov, Orlov, Nguyen, Milto, Martynov, Konstantinov & Chulisov , C. teyniei David, Nguyen, Schneider & Ziegler , C. thathomensis Nazarov, Pauwels, Konstantinov, Chulisov, Orlov & Poyarkov. In addition, the new species differs from C. pageli by having fewer ventral scales (31–37 versus 41–44), and the presence of enlarged femoral scales ( versus absent); from C. spelaeus by the presence of enlarged femoral scales and pitted scales in females (versus absent); from C. teyniei by having body pattern banded ( versus blotched); and from C. thathomensis by the presence of enlarged femoral scales ( versus absent), and having 16-21 pitted scales in females ( versus 12 pores in females). Cyrtodactylus muangfuangensis sp. nov. has six precloacal pores plus in total 21 femoral pores in the male, which are separated by poreless scales and thus differs from the following species which have a contiguous series of precloacal-femoral pores: C. bansocensis Luu, Nguyen, Le, Bonkowski & Ziegler (34), C. calamei Luu, Bonkowski, Nguyen, Le, Schneider, Ngo & Ziegler (35–39), C. darevskii Nazarov, Poyarkov, Orlov, Nguyen, Milto, Martynov, Konstantinov & Chulisov (38–44), C. hinnamnoensis Luu, Bonkowski, Nguyen, Le, Schneider, Ngo & Ziegler (36–44), C. jaegeri Luu, Calame, Bonkowski, Nguyen & Ziegler (44), C. jarujini Ulber (52–54), C. khammouanensis Nazarov, Poyarkov, Orlov, Nguyen, Milto, Martynov, Konstantinov & Chulisov (40–44), C. lomyenensis Ngo & Pauwels (39–40), C. multiporus Nazarov, Poyarkov, Orlov, Nguyen, Milto, Martynov, Konstantinov & Chulisov (58–60), C. rufford Luu, Calame, Nguyen, Le, Bonkowski & Ziegler (42–43), and C. soudthichaki Luu, Calame, Nguyen, Bonkowski & Ziegler (29).

Cyrtodactylus muangfuangensis sp. nov. differs from C. sommerladi Luu, Bonkowski, Nguyen, Le, Schneider, Ngo & Ziegler by having precloacal-femoral pores interrupted by poreless scales ( versus in a continuous row), and dorsal tubercles being arranged in 15–16 rows ( versus undefined dorsal tubercles, 0–5).
Distribution. Cyrtodactylus muangfuangensis sp. nov. is currently known only from the type locality: Muangfuang District, Vientiane Province , Central Laos ( Fig. 5 ). Etymology. The specific epithet of the new species refers to the type locality of the new species in Muangfuang District, Vientiane Province , Central Laos . Suggested common names: Muangfuang Bent-toed Gecko (English), Ki Chiem Muang Fuang (Laotian). Natural history. The type series of the new species was collected between 19:00 and 21:00h, on karst cliffs, at elevations of 255–289 m a.s.l. The surrounding habitat was karst forest ( Fig. 6 ).
