A new species of rainfrog of the <i>Eleutherodactylus milesi</i> species group (Anura: Leptodactylidae) from Guatemala

Abstract

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
