Eye: Eye color varies from yellow to grey to bright red. Extremities: The heels have well-developed pointy tubercles.
Habitat: Lowland and premontane forest to 1900 m. Ecology: May be found on low vegetation in the forest (Savage 2002). Behavior and communication: Females brood their eggs, covering them with their bodies (Myers 1969). Karyotype: 2N = 32 (DeWeese 1976) Type locality: La Loma on the trail from Chiriquicito to Boquete, Bocas del Toro Province, Panama Diet: A variety of small arthropods, including dipterans and orthopterans but not ants (Lieberman 1986).
Diagnostic description: The legs lacking webbing. Ll finger is longer than the l: lll-lV fingers have clearly expanded discs. The heel has a tuber (trace) well defined, pointy to fold. Has a defined or enlarged and pointed shaped top fold tuber; subarticular tubercles of fingers are not pointed or sharp, but can be high; the tympanum is indistinct or covered with skin. The discs of the outer fingers (III-IV) of the hand are moderately enlarged and oval.
Presents an enlarged, pointed supraocular tubercle, located at the free edge of the upper eyelid. The tarsus smooth. Palmar tubercles lacking accessories. The dorsal skin is very smooth. Holds a pointed snout profile. The groin and thigh clear lack of well-defined points and dark bars; sometimes have dark crossbars or longitudinal silver stripes(See ventral view). Adult males lack nuptial pads, although they have vocal slits.
The maximum standard length of adult males is 21 mm. and females is 26 mm.
Habitat: They live in the undergrowth of the forest and also have been found in bromeliads.
Reproduction: Its development is direct from eggs laid on the ground.
Behavior: It is nocturnal.
Distribution in Costa Rica: In the lowlands and the middle Atlantic slope in the midlands and the south end of the Pacific slope of the Cordillera de Talamanca (Savage 2002).
Distribution outside Costa Rica: They are found from southern Costa Rica to northwestern Colombia.
