Hypsiglena torquata is a species of snake commonly known as the night snake, or the desert night snake. There are several synonyms for this species, depending on different classifications and taxonomic revisions. Some of the synonyms include Hypsiglena chinensis, Hypsiglena jani, and Hypsiglena pulchella. These synonyms can often cause confusion in the scientific and conservation community, as different names may be used for the same species depending on the region or context. However, regardless of the name, the night snake is a small, nocturnal snake found in desert areas across the United States and northern Mexico.
