- Аннотация: On the basis of morphological and genetic evidence we evaluate the taxonomic status of a newly discovered forest-dwelling population of the skink genus Scincella from Keo Seima Wildlife Sanctuary, Mondulkiri Province of Cambodia. Phylogenetic analysis of 668 bp fragment of COI mtDNA gene and diagnostic morphological characters allow us to allocate the newly discovered population to the Scincella reevesii–S. rufocaudata species complex and describe it as Scincella nigrofasciata sp. nov. The new species can be distinguished from all other Southeast Asian congeners by the following combination of morphological characters: a skink with snout-vent length (SVL) 40.0–52.6 mm; relative tail length (TaL/SVL ratio) 1.25–1.94; prefrontals in broad contact; infralabials 6; primary temporals 2; relative forelimb length (FIL/SVL ratio) 0.20–0.22; relative hindlimb length (HIL/SVL ratio) 0.30–0.33; relative forearm length (FoL/SVL ratio) 0.14–0.16; adpressed forelimbs and hind limbs either overlapping (0.4–2.2 mm) or separated (1.9–2.3 mm); midbody scale rows 32–33, paravertebral scales 69–74, vertebral scales 65–69; dorsal scales between dorsolateral stripes 8; comparatively slender fingers and toes, subdigital lamellae under fourth toe 15–17; 5–7 dark discontinuous regular dorsal stripes; distinct black dorsolateral stripes, narrowing to the lateral sides and extending to 52%–86% of total tail length. We provide additional information on the holotype of Scincella rufocaudata (Darevsky and Nguyen, 1983), and provide evidence for the species status of Scincella rupicola. Our discovery brings the number of Scincella species in Cambodia to five and emphasizes the incompleteness of the knowledge on the herpetofaunal diversity of the country.
