Reproduction 
TypesHolotype: ZFMK 92573, adult male, collected by T. Hartmann and P. Geissler on 2 June 2011
Paratypes: ZFMK 88356, ZFMK 88357, ZFMK 88359, adult females and subadult male ZFMK 88358, collected by T. Hartmann in September 2008. CBC 03030, adult female and ZFMK 90311, juvenile, collected by T. Hartmann in June 2009. ZFMK 92572, ZFMK 92574, ZFMK 92575, adult females, collected by T. Hartmann and P. Geissler in June 2011. 
DiagnosisDiagnosis: Cyrtodactylus kulenensis can be separated from all other species of the C. intermedius group by having 8–11 supralabials, 8–11 infralabials, 33–38 paravertebral tubercles, 17–19 rows of longitudinally arranged tubercles, 38–44 ventrals, seven or eight expanded subdigital lamellae on the fourth toe, 11–13 unexpanded subdigital lamellae on the fourth toe, 18–21 total subdigital lamellae on the fourth toe, 12–21 enlarged femorals, nine or 10 enlarged precloacals, two or three rows of enlarged post-precloacals, two or three postcloacal tubercles, nine or 10 precloacal pores in males (N=2), enlarged femorals and enlarged precloacals continuous, proximal femorals less than one-half the size of the distal femorals, no digital pockets, maximum SVL 89.6 mm, no large dark blotches on top of head, three or four well-defined brown body bands edged with white tubercles, and body bands narrower than the beige interspaces (Grismer et al. 2021).

Comparisons: Cyrtodactylus kulenensis is most closely related to Cyrtodactylus sp. 2 (Grismer et al. 2021) but is differ-entiated from it by having a significantly higher mean number of supralabial scales (SL), paravertebral tubercles, enlarged femoral scales (FS), and enlarged precloacal scales (PS). It is differentiated from C. intermedius s.s. by having continuous as opposed to discontinuous enlarged femoral and precloacal scales (Smith 1917). It can be further differentiated from all other members of the C. intermedius group by having a significantly greater mean number of supralabials and paravertebral tubercles. It differs further from C. auralensis, C. bokorensis, C. carda-momensis, C. phuquocensis, C. thylcodactylus, and C. septimontium by having a higher mean number of proximal expanded subdigital lamellae (TLE) and is further differentiated from C. bokorensis, C. laagensis, C. kohrongensis, C. phuquocensis, and C. septimontium in having a higher mean number of enlarged precloacal scales. Cyrtodactylus kulenensis is well-separated from all other species in all three multivariate analyses. Additionally, C. kulenensis differs from its sister species Cyrtodactylus sp. 2 by an uncorrected pairwise sequence divergence of 4.4%. It is likely this percentage would be much different using a full read of ND2 and its flanking tRNAs. (Grismer et al. 2021).

Color in life: Ground color of top of head, limbs, and dorsum brown, immaculate; wide dark-brown nuchal loop edged with white tubercles extends from posterior margin of one orbit across nape to posterior margin of opposing orbit; four dark-brown, straight-edged, bands bordered with white tubercles and slightly wider beige interspaces extend from forelimb insertion to groin, no caudal bands on unicolor brown, regenerated tail; and ventral surfaces of gular region, limbs and body dull-white, bearing fine, dark, stippling (Grismer et al. 2021). 
Comment 
EtymologyThe specific epithet kulenensis is a Latinized toponymic adjective named after Phnom (=Mount) Kulen National Park, Banteay Srei District, Siem Reap Province, Cambodia. “Phnom Kulen”means “the Mountain of Lychees” in Khmer language.
