This species occurs in Western Africa (Cameroon to the Democratic Republic of the Congo) and the Caribbean (Martinique).
How the species reached Martinique is unknown, but they may have been intentionally introduced as "pets" or by workers returning from West Africa.

The natural spread of this species is very slow; however, unintentional spread by individuals for food and as folk medicine is very common.
The USDA routinely checks for the species in the luggage of travelers from West Africa, Nigeria particularly, Ghana, and Cameroon.

This species has not yet become established in the United States, but it is considered to represent a potentially serious threat as a pest, an invasive species that could negatively affect agriculture, natural ecosystems, human health, or commerce.
Therefore,  this species may be given top national quarantine significance in the United States.
