Two New Species of Eleutherodactylus (amphibia: Anura: Leptodactylidae) from Bolivia

-Eleutherodactylus fraudator, new species, E. mercedesae, new species, and E. rhabdolaemus are reported from cloud forests in Departamento Cochabamba, Bolivia. Eleutherodactylus pharangobates Duellman is placed as a synonym oíE. rhabdolaemus Duellman. Although the genus Eleutherodactylus is extraordinarily speciose in many areas of northern South America and especially on the Andean slopes, it is poorly known in southern South America. Presently, the southern terminus of the genus is in northem Argentina (Lynch 1971, Cei 1980) where only a single species, Eleutherodactylus discoidalis, is recognized. Three species have been reported from Andean Bolivia in contrast to ten species recorded from adjacent areas in Peru. While such a gradient is consistent with the geographic pattern of diversity characteristic of many groups of tropical organisms, with frogs (especially Eleutherodactylus) this gradient is partially a reflection of collecting efforts. Thus, a series of small collections made by Mercedes S. Foster in 1979 as she travelled down the eastern versant of the Bolivian Andes along the road from Cochambamba to Villa Tunari (Cannatella [1980] presented a useful map of the area) are especially noteworthy for the frogs they contain. Her collections, when added to material collected in 1959 from the same area, provide us with some important additions to the Bolivian herpetofauna particularly within the genus Eleutherodactylus. The three species previously reported from Bolivia are E. cruralis (Boulenger), E. fenestratus (Steindachner), and E. pharangobates Duellman. The cloud forests of adjacent Peru (Departamentos Ayacucho, Cuzco, and Huánuco) harbor ten species: E. cosnipatae Duellman, E. darme Duellman, E. granulosus (Boulenger), E. lindae Duellman, E. mendax Duellman, E. pharangobates Duellman, E. platydactylus (Boulenger), E. rhabdolaemus Duellman, E. salaputium Duellman, and E. scitulus Duellman. In addition to the two new species of Eleutherodactylus (described below) and E. rhabdolaemus, Foster obtained one specimen of E. fenestratus (USNM 257849, Miguelito, ca. 99 km from Cochabamba on Cochabamba to Villa Tunari road. Provincia Chapare, Departamento Cochabamba, 1770 m). This record is from the southern edge of the distribution oî E. fenestratus, a wide-ranging species recorded from several localities in the southern Amazon Basin (Lynch 1980).
