Category:True vipers

This category contains articles involving the Azemiopinae, Causinae and Viperinae subfamilies - the true vipers or pitless vipers. This listing is complete and all are valid names according to the current ITIS taxonomy. Originally, the first two subfamilies were also part of the Viperinae, which is why they are still often grouped together under this name. Nine of the entries below are redirect pages for monotypic taxa, and nominate subspecies are described in the specific name articles.
