Previous records (Liner 1964; Gehlbach & McCoy 1965; Liner, Johnson & Chaney 1976 - probably repeated by Contreras-Arquieta & Lazcano-Villarreal 1995) refer to mexicanus (Salmon, Liner, Forks & Lazcano 2004).
Introduced to: USA (Florida).
Distribution: Mexico (Chihuahua, Coahuila, Durango, Nuevo Leon, Zacatecas), USA (New Mexico, Texas).


Lampropeltis annulata

Other common names:
annulata: Mexican Milk Snake
dixoni: Dixon's Milk Snake

Chambers & Hillis (2020) did not support the taxonomic conclusions by Ruane, Bryson, Pyron & Burbrink (2014) and considered annulata a synonym of triangulum.
Distribution: Mexico (Coahuila, Guanajuato, Hidalgo, Nuevo Leon, Queretaro, San Luis Potosi, Tamaulipas, Veracruz).

Other common names:
amaura: Louisiana Milk Snake
celaenops: New Mexico Milk Snake
gentilis: Central Plains Milk Snake
multistriata: Pale Milk Snake
taylori: Utah Milk Snake
Remarks: Previously regarded as a subspecies of triangulum. Revalidated as a separate species by Ruane, Bryson, Pyron & Burbrink (2014). Includes some records previously assigned to annulata (i.e., Texas) and to triangulum syspila (i.e., Nebraska, Kansas, Oklahoma) (Ruane, Bryson, Pyron & Burbrink 2014). Collins (1991) suggested recognition of taylori as a separate species. Chambers & Hillis (2020) did not support the taxonomic conclusions by Ruane, Bryson, Pyron & Burbrink (2014) and considered gentilis a synonym of triangulum. Although North Dakota has been listed as part of the distribution by some authors (Markel 1990; Ruane, Bryson, Pyron & Burbrink 2014), this appears to be erroneous. The state was not considered part of the distribution by neither Johnson (2015), nor Hammerson (2019).

Remarks: Collins (1991) suggested recognition of multifasciata, parvirubra, and pulchra as separate species. Rodriguez-Robles, DeNardo & Staub (1999) found the pattern variation too variable to differentiate subspecies, however, their molecular data suggested two different (a northern and a southern) clade that they left unnamed.
Distribution: Mexico (Baja California Norte), USA (California, Oregon, Washington).
