Smilisca sila and puma are allopatric, whereas S. sordida is broadly sympatric with both of those species.
The majority of the species are allopatric and differ primarily in color patterns.
Where the two species are allopatric, these same morphological characters differ least.
Occurring in separate, nonoverlapping geographic areas. Allopatric populations of related organisms are unable to interbreed because of geographic separation. ◇ The development of new species as a result of the geographic separation of populations is called allopatric speciation. Compare sympatric.
