Twenty-five of these 54 species (46.3%) are country endemics and 28 of the remaining 29 are non-endemics, apart from the single non-native Hemidactylus frenatus . The distribution ranges of the 28 non-endemic species are thus: five range to the north, including the United States; 13 range farther south into Central America; six range through Central America and into South America; two range from the United States to Central America; and two occur from the United States to South America.

The 15 single-region species in the CP are as follows, using the same asterisk and numbering identifiers as above:
