Reproduction 
TypesHolotype. VFU R.2015.14, adult male, was collected on 29 March 2015 by V. Q. Luu, T. Calame and K. Thanabuaosy.
Paratypes. IEBR R.2015.35, adult male, and NUOL R.2015.15, subadult male; same collection data as was provided for the holotype. 
CommentDiagnosis. The new species differs from other congeners of the genus Cyrtodactylus by the following combination of characters: medium size, SVL reaching 72.5 mm; dorsal pattern consisting of three or four light transverse bands between limb insertions; one intersupranasal; 14–16 irregular dorsal tubercle rows at midbody, weakly developed in the paravertebral region; 27–29 ventral scale rows between ventrolateral folds; 42–43 precloacal and femoral pores in a continuous row in males, enlarged femoral and precloacal scales present; 4 or 5 postcloacal tubercles on each side; dorsal tubercles present at base of tail; subcaudal scales medially enlarged.

Comparisons. We compared Cyrtodactylus rufford sp. nov. to other species of Cyrtodactylus from Laos and neighbouring countries in the mainland Indochina region, including Vietnam, Cambodia, and Thailand based on examination of specimens (see Appendix) and data provided from taxonomic publications (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; Sumontha et al. 2015; Nguyen et al. 2015; Luu et al. 2015) (see Table 4).
Cyrtodactylus rufford sp. nov. has distinctly enlarged median subcaudals and thus differs from the following species which are lacking enlarged median subcaudals: C. bidoupimontis Nazarov, Poyarkov, Orlov, Phung, Nguyen, Hoang & Ziegler, C. bobrovi Nguyen, Le, Pham, Ngo, Hoang, Pham & Ziegler, C. buchardi David, Teynié & Ohler, C. bugiamapensis Nazarov, Poyarkov, Orlov, Phung, Nguyen, Hoang & Ziegler, C. cattienensis Geissler, Nazarov, Orlov, Böhme, Phung, Nguyen & Ziegler, C. cucdongensis Schneider, Phung, Le, Nguyen & Ziegler, C. cryptus Heidrich, Rösler, Vu, Böhme & Ziegler, C. huynhi Ngo & Bauer, C. irregularis (Smith), C. otai Nguyen, Le, Pham, Ngo, Hoang, Pham & Ziegler, C. phuocbinhensis Nguyen, Le, Tran, Orlov, Lathrop, Macculloch, Le, Jin, Nguyen, Nguyen, Hoang, Che, Murphy & Zhang, C. pseudoquadrivirgatus Rösler, Vu, Nguyen, Ngo & Ziegler, C. quadrivirgatus Taylor, C. ranongensis Sumontha, Pauwels, Panitvong, Kunya & Grismer, C. taynguyenensis Nguyen, Le, Tran, Orlov, Lathrop, Macculloch, Le, Jin, Nguyen, Nguyen, Hoang, Che, Murphy & Zhang, C. thuongae Phung, van Schingen, Ziegler & Nguyen, C. vilaphongi Schneider, Nguyen, Le, Nophaseud, Bonkowski & Ziegler, and C. ziegleri Nazarov, Orlov, Nguyen & Ho.
Cyrtodactylus rufford sp. nov. has femoral and precloacal pores in males, both of which are lacking in the following species: C. angularis (Smith), C. badenensis Nguyen, Orlov & Darevsky, C. chauquangensis Hoang, Orlov, Ananjeva, Johns, Hoang & Dau, C. cucphuongensis Ngo & Chan, C. eisenmanae Ngo, C. grismeri Ngo, C. martini Ngo, C. nigriocularis Nguyen, Orlov & Darevsky, C. oldhami (Theobald), C. pageli Schneider, Nguyen, Schmitz, Kingsada, Auer & Ziegler, C. paradoxus (Darevsky & Szczerbak), C. puhuensis Nguyen, Yang, Le, Nguyen, Orlov, Hoang, Nguyen, Jin, Rao, Hoang, Che, Murphy & Zhang, C. saiyok Panitvong, Sumontha, Tunprasert & Pauwels, C. samroiyot Pauwels & Sumontha, C. sanook Pauwels, Sumontha, Latinne & Grismer, C. spelaeus Nazarov, Poyarkov, Orlov, Nguyen, Milto, Martynov, Konstantinov & Chulisov, C. sumonthai Bauer, Pauwels & Chanhome, C. wayakonei Nguyen, Kingsada, Rösler, Auer & Ziegler, C. takouensis Ngo & Bauer, C. thirakhupti Pauwels, Bauer, Sumontha & Chanhome, and C. yangbayensis Ngo & Chan.
Cyrtodactylus rufford sp. nov. has a contiguous series of femoral and precloacal pores in males and thus differs from the following species which have poreless scales separating femoral from precloacal pores: C. bichnganae Ngo & Grismer, C. brevipalmatus (Smith), C. dumnuii Bauer, Kunya, Sumontha, Niyomwan, Pauwels, Chanhome & Kunya, C. erythrops Bauer, Kunya, Sumontha, Niyomwan, Panitvong, Pauwels, Chanhome & Kunya, C. huongsonensis Luu, Nguyen, Do & Ziegler, C. interdigitalis, C. khelangensis Pauwels, Sumontha, Panitvong & Varaguttanonda, and C. tigroides Bauer, Sumontha & Pauwels.
Cyrtodactylus rufford sp. nov. has 42–43 femoral and precloacal pores in males and thus differs from the following species which have distinctly fewer femoral and precloacal pores: C. auribalteatus Sumontha, Panitvong & Deein (10–11), C. caovansungi Orlov, Nguyen, Nazarov, Ananjeva & Nguyen (15), C. chanhomeae Bauer, Sumontha & Pauwels, C. intermedius (Smith) (8–10), C. kingsadai Ziegler, Phung, Le & Nguyen (7–16), C. roesleri (20–28), and C. soudthichaki (29).
Cyrtodactylus rufford sp. nov. can be distinguished from C. astrum Grismer, Wood, Quah, Anuar, Muin, Sumontha, Ahmad, Bauer, Wangkulangkul, Grismer & Pauwels by its smaller size (maximum SVL 72.5 mm versus 108.3 mm), having fewer ventral scale rows (27–29 versus 31–46), fewer lamellae under the fourth toe (18– 19 versus 20–24), and more femoral and precloacal pores in males (42–43 versus 31–38); from C. jarujini Ulber by its smaller size (maximum SVL 72.5 mm versus 90.0 mm), having fewer ventral scale rows (27–29 versus 32–38), and fewer femoral and precloacal pores in males (42–43 versus 52–54); from C. lekaguli Grismer, Wood, Quah, Anuar, Muin, Sumontha, Ahmad, Bauer, Wangkulangkul, Grismer & Pauwels by its smaller size (SVL reaching 72.5 mm versus 103.5 mm), having fewer ventral scales (27–29 versus 31–43), and more femoral and precloacal pores in males (42–43 versus 30–36); from C. multiporus by its smaller size (maximum SVL 72.5 mm versus 98.0 mm), having fewer ventral scale rows (27–29 versus 30–38), and fewer femoral and precloacal pores in males (42– 43 versus 58–60); from C. teyniei David, Nguyen, Schneider & Ziegler by its smaller size (maximum SVL 72.5 mm versus 89.9 mm), having fewer ventral scale rows (27–29 versus 38), the presence of a nuchal band (versus being absent), and having a banded dorsal pattern (versus blotched).
Cyrtodactylus rufford sp. nov. is similar to the members of the C. phongnhakebangensis group (Nazarov et al. 2014) including C. khammouanensis, C. lomyenensis, C. jaegeri, C. darevskii, and C. phongnhakebangensis Ziegler, Rösler, Herrmann & Vu in having a high number of femoral and precloacal pores and in the dorsal pattern. However, the new species can be distinguished from C. khammouanensis by having fewer ventral scale rows (27– 29 versus 32–38), fewer dorsal tubercles at midbody (14–16 versus 16–21), fewer lamellae under the fourth toe (18–19 versus 20–23), dorsum of head with dark blotched markings (versus absent), having light transverse bands between limb insertions with wavy margins (versus transverse bands with smooth margins), and tail with light rings (versus light bands); from C. lomyenensis by having fewer ventral scale rows (27–29 versus 35–36), fewer supralabials (10–12 versus 13–14), and more femoral and precloacal pores in males (42–43 versus 39–40); from C. darevskii by its smaller size (maximum SVL 72.5 mm versus 100.0 mm), having fewer ventral scale rows (27–29 versus 38–46), and fewer ventral scales between mental and cloacal slit (153–167 versus 180–208); from C. jaegeri by having fewer ventral scale rows (27–29 versus 31–32), fewer femoral and precloacal pores in males (42–43 versus 44), fewer lamellae under the fourth toe (18–19 versus 20–23), and having irregular shaped light transverse bands between limb insertions (versus regular shaped light transverse bands); and from C. phongnhakebangensis by its smaller size (maximum SVL 72.5 mm versus 96.3 mm), having fewer ventral scale rows (27–29 versus 32– 42), generally more femoral and precloacal pores in males (42–43 versus 32–42), and fewer ventral scales between mental and cloacal slit (153–167 versus 180–208). For more details see Table 5 in LUU et al. 2016.
 
EtymologyThe new species is named in honour of the Rufford Foundation (UK) for its support to herpetofaunal research and conservation in Laos. The species epithet is to be treated as a noun in apposition, invariable. As common names, we suggest
