Hebius maximus

Species of snake

Hebius maximus, the western China keelback, is a species of snake of the family Colubridae. The snake is endemic to Southwestern China (Chongqing, Sichuan, northwestern Guizhou).[1][2] Originally described as a subspecies of Amphiesma sauteri (=Hebius sauteri), its validity has been doubted;[1][2] however, it was revalidated by a 2022 study based on morphological and molecular evidence. The evidence even warranted the recognition of Hebius maximus as a full species.[2]

Etymology

The specific name maximus refers to this taxon having the highest count of ventral scales among what at the time were the three subspecies of H. sauteri.[1][2]

Description

Hebius maximus is a small to medium-sized snake, reaching 597 mm (23.5 in) in total length. The tail is relatively long, 25–33% of the total length. Dorsal colouration is reddish-brown or grayish brown, while the ventrum is cream white. An ill-defined dark olive dorsal streak scattered with black spots runs from neck to tail.[2]
