Identification: Eleutherodactylus portoricensis is a small leptdodactylid (rain frog) about 32-42 mm (1.25-1.65 in) long (Schwartz and Henderson, 1991; Joglar, 1998). The dorsal coloration of adults is highly variable, ranging from yellow, tan or gray, with or without a variable pattern, sometimes exhibiting light lateral stripes (Schwartz and Henderson, 1991; Joglar, 1998; Rivero, 1998). Mountain coqui are very easily confused with E. coqui and exhibit many of the pattern variations seen in this similar species (Schwartz and Henderson, 1991; Rivero, 1998; also illustrated in Joglar, 1998). Like E. coqui, mountain coqui have toe disks (toepads) for climbing (Joglar, 1998). The males' call is a repeated "ko-KEE" that also sounds confusingly like the call of E. coqui; however, these two notes are normally repeated at shorter intervals in E. portoricenis than in E. coqui (Rivero, 1998). A CD recording of both these species is provided by Rivero (1998). Also see the species account titled "Eleutherodactylus coqui Thomas, 1966" on this website.
Size: 32-42 mm head-body length
Native Range: The mountain coqui is native to the moist highlands of Puerto Rico (Schwartz and Thomas, 1975; Frost, 1985; Schwartz and Henderson, 1985, 1991; Powell et al., 1996; Joglar, 1998; Rivero, 1998; Hedges, 1999; Thomas, 1999).

Means of Introduction: Prior to 1965, a herpetologist released several E. portoricensis in Sunset Park, South Miami, Dade County, Florida (King and Krakauer, 1966; Smith and Kohler, 1978). The identity of the species of Eleutherodactylus involved was not verified.
Status: Not established (King and Krakauer, 1966; Smith and Kohler, 1978). The specific identity of these Eleutherodactylus remains questionable (see remarks below).
