Eleutherodactylus juanariveroi, the Plains Coqui or Llanero Coqui (Spanish: Coquí Llanero) is an endangered species of coqui, a frog species, endemic to Puerto Rico. It was discovered in 2005 by Neftalí Rios and was named after Puerto Rican herpetologist Juan A. Rivero, in honor of his contributions to Puerto Rican herpetology. It is only found in the old Naval Base of Sábana Seca in Toa Baja, Puerto Rico. It is characterized by a high frequency chip-like sound, a light brown skin color and a strip between the eyes. It is the smallest species of coqui. The Department of Natural Resources of Puerto Rico has added this species to the endangered species list, and has designated its critical habitat likewise. Its status under the Endangered Species Act is under review.
