Storeria hidalgoensis

Storeria hidalgoensis, commonly known as the Mexican yellow-bellied brown snake or the Mexican yellowbelly brown snake, is a nonvenomous snake in the family Colubridae. It is endemic to the Sierra Madre Oriental of Mexico.

Animal name origin

The specific name, hidalgoensis, is composed of hidalgo-, which refers to the Mexican state in which the type specimen was collected, and the Latin suffix -ensis, which means "belonging to".

Appearance

Adults are small and somewhat slender with a maximum length of 33.7 cm (13.3 in). Dorsal body color varies from gray to light brown, tan, reddish, or dark brown (grayish to dark brown in preservative) usually with small gray flecks but no dark spots or crossbands. Ventral coloring is either gray to pink, or may have dark gray pigment at least laterally. Its head is black, especially posteriorly, with small gray flecks. A dark wedge-shaped mark lies behind each parietal and a light spot is usually present within the mark. Labials are either gray, or contain variable amounts of dark pigment with the fifth supralabial being the lightest of the series. The dorsal scales are without pits with some faintly keeled.
