viperinae

Until relatively recently, two other genera were also included in the Viperinae.

Despite its common names, it is not a member of the Subfamily Viperinae.

Nevertheless, these groups, together with the genera currently recognized as belonging to the Viperinae, are still often referred to collectively as the true vipers.

The Viperinae, or viperines, are a subfamily of venomous vipers found in Europe, Asia and Africa.

The Viperinae are found in Europe, Asia and Africa, but they are not found in Madagascar.

Rather, it is attributed to Oppel, based on his Viperini as a distinct family group name, despite the fact that Gray was the first to use the form Viperinae.

Today, however, the monophyly of the Viperinae and the crotalines as a whole is undisputed, which is why they are treated here as a subfamily of the 'Viperidae'.
