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
[edit | edit source]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
[edit | edit source]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]
Habitat
[edit | edit source]Hebius maximus occurs in subtropical mountain regions at elevations of about 812–1,200 m (2,664–3,937 ft) above sea level in coniferous forests, large forest clearings, and agricultural areas. It is diurnal, active at dusk. Its prey includes earthworms, slugs, and tadpoles.[2]
