About Pareas atayal You, Poyarkov & Lin, 2015
Pareas atayal is a slender yellow-brown snake that can grow to approximately 50 cm (20 inches) in total length. The dorsal surface of this species is primarily yellow-brown or ochre, with flanks that are slightly lighter in color. The belly and chin are yellow-white or cream. Distinct dark vertical bars, each roughly two scales wide, are present along the sides of the snake. Very small brownish dots are scattered across the dorsum and flanks, with a lower density of dots on the flanks than on the dorsum, and an even lower density on the ventral surface than on the flanks. Two thin, clearly defined black stripes extend from the upper and lower edges of each postorbital scale. The lower postorbital stripe reaches the front section of the seventh supralabial scale, and does not extend further onto the lower jaw or chin. The upper postorbital stripes meet at the base of the snake's head, forming an M-shaped arch.
