The genus comprises just one species. This is Bothrochilus boa (The Ringed Python) known only from the Bismarck Islands, north of New Guinea. It is endemic to the region. The type locality is New Ireland. The species does not occur on the island of Mussau.
The species cannot be confused with any other Australasian species. Refer to O'Shea (1996) and references therein for further diagnostic information. Photos of the species are published in Hoser (1993b) and O'Shea (1996). The species occurs in both banded/blotched and unbanded forms. The unmarked specimens are similar in many respects to L. albertisi. However the two species are separated by distribution. B. boa is also separated from L. albertisi by its smaller adult size (under 2 metres), reduced labial pit system, lower scale counts and a suite of other characters.
Refer to McDowell (1975) for further details.
