Chiala Mountain Salamander

A medium-sized, slender salamander typically measuring 4.5–5.5 inches (11.4–14.0 cm) in total length. Body is gracile and elongate with relatively short limbs and a long, laterally compressed tail. Dorsal coloration is dark brown to nearly black, often with a subtle bronze or coppery sheen, particularly evident along the dorsolateral regions. The dorsum may exhibit faint, irregular lighter spotting or flecking, especially in younger individuals. A faint dorsal stripe may be present along the vertebral line in some specimens. The head is relatively small and flattened, with small eyes positioned laterally. Costal grooves are prominent, typically numbering 14–15 between forelimb and hind limb insertions, a key diagnostic feature of hynobiid salamanders. The tail comprises approximately 50% of total length and is distinctly flattened laterally, bearing a subtle dorsal crest that may be barely discernible. Ventral surface is dark gray to black, sometimes with lighter marbling or spotting on the throat and belly. Skin texture is smooth and moist. Limbs are short and relatively weak, with limited webbing between toes. Primarily inhabits cool, mountain streams and seepage areas on the Chiala Mountains at moderate to high elevations, typically in or near flowing water among moss-covered rocks and leaf litter. Associated with pristine headwater habitats with moderate water temperature and high oxygen content. Diet consists of small aquatic invertebrates including copepods, small insect larvae, and other microcrustaceans.
