Drymarchon couperi

Indigo Snake

Indigonatter

Indigosnog

1842 Coluber couperi Holbrook
Georgia couperi Baird & Girard 1853
Spilotes couperii Cope 1860
Spilotes corais couperii Lönnberg 1894
Drymarchon corais couperi Strecker 1915
Drymarchon couperi Collins 1991
2016 Drymarchon kolpobasileus Krysko, Granatosky, Nuñez & Smith (syn. Folt, Bauder, Spear, Stevenson, Hoffman, Oaks, Wood, Jenkins, Steen & Guyer 2019; Guyer, Folt, Hoffman, Stevenson, Goetz, Miller & Godwin 2019)

Other common names:
kolpobasileus: Gulf Coast Indigo Snake
Remarks: Previously regarded as a subspecies of corais. Collins (1991) suggested recognition of couperi as a separate species, which is now generally followed. Presence in South Carolina is considered doubtful (Enge, Stevenson, Elliott & Bauder 2013; Grosse 2013). Although it occurred naturally, it is probably extirpated in Alabama, although a small population may still survive (Enge, Stevenson, Elliott & Bauder 2013).
