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. The pit vipers of the Crotalinae subfamily, a much larger group, have their own category: Category:Pit vipers. A few of the entries below are redirect pages involving monotypic taxa, with the redirects linking to the higher taxon, but the rest are actual articles.
