What is the common name of Notophthalmus viridescens?

Notophthalmus viridescens is commonly called the eastern newt.

This newt is native to eastern North America, where it occupies ponds, wetlands, forests, and other habitats with suitable water. Its life cycle commonly includes three stages: an aquatic larva, a terrestrial red eft, and an adult that returns to water. The red eft stage is especially recognizable for its bright orange coloration and rougher skin.

The eastern newt belongs to the family Salamandridae and is a newt rather than a frog. Adults are generally olive or greenish, often with dark spots and a yellowish underside marked by black spots. The species is divided into several subspecies, including the red-spotted newt, Notophthalmus viridescens viridescens.

It is often confused with European newts or the fire salamander, but those are different animals from different geographic regions. “Eastern” refers to its distribution in North America, not to a separate genus or a particular color phase.
