In the above list, a taxon author in parentheses indicates that the species was originally described in a different genus.

Taxonomy Due to the strong morphological similarity, these snakes were classified in the genus Agkistrodon until very recently. However, by 1999 cladistic studies clearly showed that Agkistrodon did not form a clade (indeed, it was not even paraphyletic) and was thus split into several genera.

A new species, G. tsushimaensis, was described by Isogawa, Moriya & Mitsui (1994). It is referred to as the Tsushima island pitviper and is found only on Tsushima Island, Japan.
