Biodiversity of the family Colubridae








Genus
Coluber

North American Racer

Nordamerikanische Schwarznatter

Nordamerikansk Pilsnog

1758 Coluber Linnaeus (type species: Coluber constrictor Linnaeus 1758)
1817 Scoliophis Davis, Bigelow & Gray (type species: #Scoliophis atlanticus = Coluber constrictor Linnaeus 1758)
1853 Bascanion Baird in Baird & Girard (type species: Coluber constrictor Linnaeus 1758)
Contents: 1 species, which is not endemic.
Endemism: 0% 100%
Other common names:
Holarctic Whip Snakes, Holarctic Racers (used when the genus also included Old World species)
Remarks: Now restricted to contain a single species. Previously included the species now placed in Argyrogena, Bamanophis, Dolichophis, Hemerophis, Hemorrhois, Hierophis, Orientocoluber, and Platyceps. The genera Masticophis and Ptyas have been synonymized with Coluber by some authors (see remarks under these genera). Apparently, the common names "racer" and "whip snake" are used randomly for snakes of the genera mentioned above, with the exception of C. constrictor, which is generally referred to as the North American Racer.
Distribution: As for the single species.

1955 Coluber constrictor helvigularis Auffenberg
1970 Coluber constrictor etheridgei Wilson
1970 Coluber constrictor latrunculus Wilson

Other common names:
anthicus: Buttermilk Racer
constrictor: Northern Black Racer
etheridgei: Tan Racer
flaviventris: Eastern Yellow-bellied Racer
foxi: Blue Racer
helvigularis: Brown-chinned Racer
latrunculus: Black-masked Racer
mormon: Western Yellow-bellied Racer
oaxaca: Mexican Racer, Southern Racer
paludicola: Everglades Racer
priapus: Southern Black Racer
Remarks: Fitch, Brown & Parker (1981) suggested recognition of mormon as a separate species, but the results of Corn & Bury (1986) did not support this, and most subsequent publications have retained it as a subspecies of constrictor (e.g., Greene 1984; Corn & Bury 1986; Dixon 2000). Although previously reported from Durango (e.g., Smith 1971; Wilson 1978), presence in the state is undocumented (Webb 2001). Smith (1971) concluded that all Pacific slope records from Mexico (Colima, Oaxaca) appear to be erroneous.
Introduced to: Bahamas (Grand Bahama).
