Geographic Range [top]

Range Description:This species occurs in Cuba, the Bahamas, the Swan Islands (Honduras), and southern Florida in the United States. The range of this gecko includes the Dry Tortugas, extreme southeastern mainland Florida, and the Florida Keys (subspecies notatus, common throughout the larger Upper and Lower Keys, Lawson et al. 1991); Little and Great Bahama Banks; Rum Cay Bank; Great Inagua Island; Cuba, including Archipielago de los Canarreos, Cayos de San Felipe, Cayos los Ballenatos; Isla de la Juventud; Morant Cays; Pedro Cays; and the Swan Islands, Honduras (Schwartz and Henderson 1991, which describes subspecific distributions). The species has been reported as an introduction to Colombia (F. Castro pers. comm., cited in Uetz and Hallerman 2015).

Population [top]

Population:This species is known from many sites that are widely-distributed throughout the historical range. The total adult population size is unknown but surely exceeds 100,000. This lizard is abundant in southern Florida (Bartlett and Bartlett 1999). Its population size is large and probably stable.
Current Population Trend:Stable

Habitat and Ecology [top]

Habitat and Ecology:Schwartz and Henderson (1991) characterized this species as xerophilic and sometimes mesophilic. It occurs among or under leaf litter or debris on the floor of hammocks, coppice, coconut groves, ornamental gardens, pine lands, vacant lots, cave entrances, or around buildings (Schwartz and Henderson 1991), and it is often abundant under flotsam on beaches just above the high tide line (Bartlett and Bartlett 1999). It is uncommonly edificarian but often is associated with human debris and abandoned dwellings (Schwartz and Henderson 1991). Eggs are laid in rotting logs, at the bases of palm fronds, or under logs, boards, driftwood, coconut husks, or other debris (Schwartz and Henderson 1991).
Continuing decline in area, extent and/or quality of habitat:No
