FMNH 263239–40 have complete tails. The posterior section of the tail in CBC 04395 is regenerated and somewhat mottled. Color pattern of the juveniles FMNH 263238 and 262241 is much bolder and contrasting. See Table 3 for variation in meristic among the type series.</p><p>......continued on the next page</p><p>Distribution. Cyrtodactylus kiriromensis sp. nov. is known only from the type locality at Kirirom National Park but is expected to range farther throughout the Sruoch Plateau.</p><p>Etymology. The specific epithet is a toponym of the type locality Kirirom National Park, Kampong Speu Province, Cambodia.</p><p>Natural history. All specimens of the new species were found at night in disturbed or intact semi-evergreen forest, often near a stream, at 310–600 m asl. The holotype was found on a vertical tree trunk 5 m from a cascading stream in an open area at an old dam site within disturbed semi-evergreen forest. FMNH 263238–40 were found along a stream in semi-evergreen forest on a 1.2 m diameter boulder on the stream bank (FMNH 263238), on a 2x 2 m rock face 1.5 m above the stream (FMNH 263239), and on a large rock face 2.5 m above the ground, 1.5 m from the stream (FMNH 263240). FMNH 263241 was found in disturbed semi-evergreen forest mixed with bamboo on a boulder approximately 100 m from a stream. CBC 03495 was found after a light rain in semi-evergreen forest on the base of a tree 0.3 m above the ground.</p><p>Comparisons. The phylogenetic relationships of Cyrtodactylus kiriromensis sp. nov. delimit it from all other species of intermedius group wherein it is part of a southern clade composed of C. bokorensis, C. borgattaorum, C. laangensis, C. phuquocensis, C. regicavernicolus and its sister species C. septimontium (Fig. 3) from which it differs by an uncorrected pairwise sequence divergence of 3.2–4.3%. From the other species it differs by a range of 8.1% from C. bokorensis to 8.9% from C. laangensis . The ANOVA analyses recovered multiple statistically different mean morphometric and meristic values between C. kiriromensis sp. nov. and the other species of the southern clade (Table 2; Fig. 4). Cyrtodactylus kiriromensis sp. nov. differed from C. bokorensis, C. regicavernicolus, and C. laangensis in that the enlarged femoral scales were not separated, as opposed to being separated from the precloacal scales by smaller granular scales. It often differs further from C. bokorensis, C. laangensis, and C. septimontium in that proximal enlarged femoral scales are usually not less than one-half the size of the distal femoral scales. From C. regicavernicolus it differed by have a nearly unicolor top of head as opposed to the top of the head bearing dark markings. This characteristic was variable in C. bokorensis and C. laangensis . The distribution of the categorical characters are in Table 1S. Table 4 provides summary statistics for the species discussed above. The more distantly related C. borgattaorum was not included in the statistical analyses due the low sample size of adults (n=1) and C. phuquocensis was excluded due to notable potential differences in the counting of meristic characters.</p></div>	https://treatment.plazi.org/id/73618790F357FFD6879FFDA82F7A7D60	Public Domain	No known copyright restrictions apply.
