Materials examined. PUERTO RICO – Arecibo • Mata de Plátano Field Station and Nature Reserve; 18.414, -66.729; 151 m above sea level; Justin Matthew Bernstein, Camilo Andrés Calderón-Acevedo, Pedro Ivo Mônico, Lázaro Willian Viñola-Lopez, J. Angel Soto-Centeno; Individual 1 – found in leaf litter on west side of field station at 6:00 PM; Individual 2 – found on east wall of field station at 9:30 PM; Individual 3 – found in leaf litter at far end of open field 73 m south of field station.
Identification. Three adults, identified by a combination of morphology and geographic distribution. Diagnosed by eye color (tan/brown) and color pattern (no dorsal stripe, saddle pattern on back and dorsolateral lines). Eleutherodactylus monensis , E. cooki, E. cochranae , E. portoricensis , E. karlschmidti ,E. gryllus , E. locustus , E. wightmanae , E. eneidae , E. richmondi , E. unicolori , and E. jasperi are all outside the range of our study area.Eleutherodactylus brittoni found in meadows and has a narrow black streak at the tip of the snout, stretching and continuing along the flanks (absent in our observed individuals).Eleurtherodactylus portoricensis has silver or chalky white eyes (tan/brown eyes in our individuals) and restricted to mountains.Eleutherodactylus hedricki has a pronounced constriction behind the head and a shallow furrow on the middle of the back from the head to the sacrum (absent in our individuals). Eleutherodactylus richmondi has yellow or white lines on each side of the head, that range from the tip of the snout to near the vent (absent in our individuals). Eleutherodactylus antillensis has a dorsal stripe that stretches from the tip of the snout to the vent (absent in our individuals) and reddish eyes (tan/brown in our individuals).

Angel Soto-Centeno; Individual 1 – found in leaf litter near entrance of open field, 73 m south of field station; Individual 2 – caught in mist net placed at path of open field 75 m south of field station 7:40 PM.
Identification. Two adults, identified by a combination of morphology and geographic distribution; diagnosed by its thin, mid-dorsal stripe on the head and body, and reddish eyes. Similar to the identification of E. coqui , E. monensis , E. cooki, E. cochranae , E. portoricensis , E. karlschmidti , E. gryllus , E. locustus , E. wightmanae , E. eneidae ,E. richmondi , E. unicolori , and E. jasperi are all outside the range of our study area. Eleutherodactylus brittonifound in meadows and has a narrow black streak at the tip of the snout, stretching and continuing along the flanks (absent in our observed individuals). Eleurtherodactylus portoricensis has silver or chalky white eyes (tan/brown eyes in our individuals) and restricted to mountains. Eleutherodactylus hedricki has a pronounced constriction behind the head and a shallow furrow on the middle of the back from the head to the sacrum (absent in our individuals).Eleutherodactylus richmondi has yellow or white lines on each side of the head, that range from the tip of the snout to near the vent (absent in our individuals). Eleutherodactylus coqui may or may not have the dorsal stripe that stretches from the tip of the snout to the vent that is seen in E. antillensis , E. coqui has tan/brown eyes (reddish in our individuals).
