|Distribution||Cambodia (Kampong Speu)|
Type locality: Camp 1, Phnom Aural Wildlife Sanctuary, Kampong Speu Province, Cambodia (1201’N, 10408’E; 549 m in elevation)
|Types||Holotype: LSUHC 7399, adult male, collected on 6 August 2005 by Neang Thy, L. Lee Grismer, Perry L. Wood, Jr., Jesse L. Grismer, Thou Chav, Timothy M. Youmans, and Armando Ponce. Paratypes. Adult male LSUHC 7396, adult females LSUHC 7397–98 and 7410 all bear the same collection data as the holotype. Adult female LSUHC 7346 was collected at the same location as the holotype on 5 August 2005 by the same collectors.|
|Diagnosis||Diagnosis. Adult males reaching 83.5 mm SVL, adult females reaching 84.3 mm SVL; eight or nine supralabials, 9–11 infralabials; 29–32 paravertebral tubercles; 17 or 18 longitudinal rows of dorsal tubercles; 37–44 rows of ventral scales; six or seven expanded subdigital lamellae proximal to the digital inflection, 12–15 unmodified, distal, subdigital lamellae; 19–21 total subdigital lamellae on fourth toe; enlarged femoral and precloacal scales continuous; 23–28 enlarged femoral scales; proximal femoral scales less than half the size of distal proximal scales; 7–9 enlarged precloacal scales with pores on each in males; two or three rows of enlarged post-precloacal scales; three postcloacal tubercles; no pocketing present between digits of hind or forefeet; dark pigmented blotches present on top of head; posterior border of nuchal loop rounded, not chevron-shaped; four or five dark body bands (see Tables 7 and 9 in Murdoch et al. 2019).|
Comparisons. Cyrtodactylus auralensis sp. nov. is a member of the western group and the sister species to a lineage containing the remaining species of that group C. intermedius Thai clade [C. thylacodactylus sp. nov. [C. intermedius complex incertae sedis 1 [C. cardamomensis sp. nov.]]] from which it is separated by 7.1%–9.0% sequence divergence (Table 4 in Murdoch et al. 2019). The PCA shows Cyrtodactylus auralensis sp. nov. is separated in morphospace along PC1 and PC2 from all other members of the C. intermedius complex with the exception of C. cardamomensis sp. nov. with which there is slight overlap (Fig. 6). The DAPC analysis shows the 95% confidence intervals of Cyrtodactylus auralensis sp. nov. as distinct from C. thylacodactylus sp. nov., C. laangensis sp. nov. and C. bokorensis sp. nov., overlapping slightly with C. intermedius and C. phuquocensis and grouping closely with C. septimontium sp. nov. and C. cardamomensis sp. nov. (Fig. 7). Cyrtodactylus auralensis sp. nov. is well- differentiated from all other members of the C. intermedius complex, with the exception of C. intermedius, by having varying combinations of statistically different mean values of supralabial and infralabial scales; paravertebral tubercles; longitudinal rows of tubercles; ventral scales; unmodified, expanded, and total number of subdigital lamellae; enlarged femoral scales, precloacal scales, and postcloacal tubercles (Table 6). It differs further from all other members of the complex in having the consistent presence of distinct pigmented blotches on top of the head, although some individuals of C. bokorensis sp. nov., and C. laangensis sp. nov. have blotches but they are not consistently present. Rounded posterior border of the nuchal loop separates C. auralensis sp. nov. from C. bokorensis sp. nov. Continuous contact between precloacal and femoral scales differentiates it from C. laangensis sp. nov. and some individuals of C. bokorensis sp. nov. in which contact is variable. Proximal femoral scales being less than one-half the size of the distal femorals differentiates it from C. cardamomensis sp. nov. and C. thylacodactylus sp. nov. Lack of interdigital pocketing separates it from C. thylacodactylus sp. nov. (Table 7).
|Etymology||The specific epithet, auralensis, is a noun in apposition in reference to the type locality of Phnom Aural mountain, the highest mountain in Cambodia, to which it presumably endemic.|
