ABSTRACT
A distinctive new species of Atelopus is described from Parque Nacional Chirripó Grande, Cordillera de Talamanca (3 400-3 500 m). It closely resembles populations of the Atelopus ignescens complex from the Andes of northern Ecuador and southern Colombia. it differs most significantly from these frogs in the pattern of spiculae and coni development on the throat, chest, hands and feet. The Costa Rican species appears to be an outlier of the complex inexplicably separated geographically from its nearest allies by an over land distance of about 1 600 km. Rev. Biol. Trop. 57 (1-2): 381-386. Epub 2009 June 30.
Se describe una nueva especie de Atelopus del Parque Nacional Chirripó Grande, Cordillera de Talamanca (3 400-3 500 m sobre el nivel del mar). Se parece a poblaciones del complejo de Atelopus ignescens de los Andes del norte de Ecuador y del sur de Colombia. Principalmente difiere de estas ranas en el patrón de desarrollo de espículas y conos en la garganta, pecho, manos y pies. La especie de Costa Rica es atípica dentro del complejo por estar inexplicablemente separada geográficamente de sus más cercanos representantes por una distancia aproximada de 1 600 km por tierra.

A recently discovered new species of diploglossine lizard is described from west-central Panama. The distinctiveness of the nominal genera Celestus and Diploglossus is confirmed; the new form represents the southernmost record for the genus Celestus. A summary of selected characteristics and general distribution is presented for all recent species of diploglossines, including members of the Antillean genera Saurisia and Wetmorea and the South American genus Ophiodes. A systematic key to mainland members of the genus Celestus is provided. Rev. Biol. Trop. 56 (2): 845-859. Epub 2008 June 30.
Se describe una especie nueva de lagarto diploglossino recientemente descubierta en el centro-oeste de Panamá. Confirmamos la peculiaridad de los géneros nominales Celestus y Diploglossus. La nueva especie representa el registro más al sur del género Celestus. Se presenta un resumen de características selectas y de la distribución general de todas las especies recientes de diploglossinos, incluyendo a los miembros de los géneros antillanos Saurisia y Wetmorea y del género suramericano Ophiodes. Se provee una clave sistemática para los miembros de tierra firme del género Celestus.

A new rainfrog of the Eleutherodactylus milesi group is described from the Sierra de Xucaneb, Guatemala. It is compared to the other 11 upland species from southern Mexico, Guatemala and Honduras referred to the group. Within the milesi group the new species differs from the other five forms which also have toe fringes in size of the finger disks, the snout shape in profile and the amount of toe webbing and dorsal tuberculation. Difficulties in distinguishing among the character states for the tympanum (distinct, indistinct and hidden) and between toe ridges and fringes indicate that very subtle differences separate recognized species.
