Tropidophis pilsbryi

Tropidophis pilsbryi, commonly known as Pilsbry's dwarf boa or the Cuban white-necked dwarf boa, is a species of snake in the family Tropidophiidae. The species is endemic to Cuba.

Etymology
Both the specific name, pilsbryi, and one of the common names, Pilsbry's dwarf boa, are in honor of American malacologist Henry Augustus Pilsbry.

Subspecies
Two subspecies are recognized, including the nominate subspecies:
 * Tropidophis pilsbryi pilsbryi Bailey, 1937 – eastern Cuba
 * Tropidophis pilsbryi galacelidus Schwartz & Garrido, 1975 – central Cuba

Taxonomy
In 2002 Hedges elevated the subspecies T. p. galacelidus to a full species, T. galacelidus.
