Boa imperator

Central American Red-tailed Boa, Central American Boa, Imperial Boa

Kaiserboa

Kejserboa

Boa constrictor imperator Forcart 1951
1842 Boa eques Eydoux & Souleyet (Stimson 1969)
1863 Boa diviniloquax mexicana Jan (Stimson 1969)
Boa mexicana Boulenger 1893
Constrictor constrictor mexicanus Stull 1935

1906 Epicrates sabogae Barbour (Reynolds, Niemiller & Revell 2014)
Constrictor constrictor sabogae Barbour & Loveridge 1929
Boa constrictor sabogae Forcart 1951
Boa imperator sabogae Reynolds, Niemiller & Revell 2014

Other common names:
mexicana: Mexican Common Boa
sabogae: Saboga Boa
Remarks: Previously considered a subspecies of constrictor (e.g., Forcart 1951). Formerly included sigma, to which species most West Mexican records of imperator refer. Revalidated as a separate species by Reynolds, Niemiller & Revell (2014). Based on the distribution maps in Card, Schield, Adams, Corbin, Perry, Andrew, Pasquesi, Smith, Jezkova, Boback, Booth & Castoe (2016), both imperator and sigma appear to occur in Guerrero, Oaxaca, and Puebla. Older records from these states may therefore represent either of the two species.
Introduced to: Mexico (Quintana Roo: Cozumel), USA (Iowa).
Distribution: Belize, Colombia (incl. Gorgona Island, Providencia, San Andres, Santa Catalina), Costa Rica, Ecuador, El Salvador, Guatemala, Honduras (incl. Islas de la Bahia [Barbareta, Cayos Cochinos (Cayo Cochino Major, Cayo Cochino Pequeño), Guanaja, Roatan, Utila]), Mexico (Campeche, Chiapas, Guanajuato, Guerrero, Hidalgo, Nuevo Leon, Oaxaca, Puebla, Queretaro, Quintana Roo, San Luis Potosi, Tabasco, Tamaulipas, Veracruz, Yucatan), Nicaragua (incl. Islas del Maiz [Isla Grande del Maiz, Isla Pequeña del Maiz]), Panama, Peru.
