We placeHyla roeschmanni as a junior synonym of Hypsiboas raniceps Cope, 1862. Because the holotype ofHyla roeschmanni was destroyed, we designate a neotype from Department Beni, Bolivia, andprovide a description of the neotype. Key words: Anura, Bolivia, Hyla roeschmanni, Hypsiboas raniceps, Hylidae, neotype, newsynonymIntroductionMuch taxonomic research has been accomplished on Bolivian frogs during the last fifteenyears (e.g. la Riva et al., 2000; Köhler, 2000). This work has lead to the clarification ofmany taxonomic problems, the description of new species, etc. Nevertheless, manyspecies remain unnamed (unpublished personal data) and certain minor problems awaitresolution. For example, some species named long ago have not been reported again sincetheir original descriptions. This is the case with Hyla roeschmanni De Grys, 1938 (see Dela Riva, 1990; De la Riva et al., 2000).According to Duellman (1977), the type specimen of H. roeschmanni was destroyed.This was confirmed subsequently by us via personal correspondence with the ZoologicalMuseum of Hamburg (J. Hallermann, pers. comm., 2001). Moreover, H. roeschmanni isonly known from the imprecise type locality "Provinz Beni, Bolivien, südlichesQuellgebiet des Amazonas" (Province Beni, Bolivia, southern headwaters of the Amazon)(De Grys, 1938). The name has not been associated with any known population (DuellmanPADIAL ET AL.64                                       © 2006 Magnolia Press1230ZOOTAXA in Frost, 1985). The type locality “Provinz Beni” is imprecise because Beni is the name ofa large (213,564 square km) Bolivian department composed of eight provinces, none ofthem named Beni; the author did not provide a specific locality. The departament of Benimainly contains lowland savannas and gallery forests but also includes extensive areas ofAmazonian forests in its northern part. Therein, the diversity of species of hylids is high,and both Amazonian and Chacoan species have been reported (Reichle, 1997; De la Rivaet al., 2000). Although the assignment of H. roeschmanni to any known population ishampered by the lack of precise locality data, the original description is sufficientlydetailed to compare it with the species occurring in the general region of the type locality.The description matches precisely with juveniles of Hypsiboas raniceps Cope, 1862, acommon, broadly distributed species that occurs in most habitats of Beni department. Wepropose that Hyla roeschmanni is a junior synonym of Hypsiboas raniceps; because theholotype is lost and was apparently destroyed in World War II, we designate herein aneotype from Beni department, Bolivia.Material and methodsFor nomenclature of Hylidae we follow Faivovich et al. (2005) and for the synonymy wefollow Frost (2004). Measurements were taken with a digital calliper to the nearest 0.01mm, but following Hayek et al. (2001), for avoiding pseudo precision, we rounded allmeasurements to only one decimal. Webbing formulae follow Savage and Heyer (1967) asmodified by Myers and Duellman (1982) and Savage and Heyer (1997). Museumabbreviations follow Leviton et al. (1985).ResultsHypsiboas raniceps Cope, 1862Hypsiboas raniceps Cope, 1862, Proc. Acad. Nat. Sci. Philadelphia, 14: 353.

Minor discrepanciesare: head length equal to head width in the holotype, probably because of differentmeasurement points (i. e. posterior margin of the lower jaw vs. rictus); the fingers aredescribed as free in the holotype, which could be a result of poor (dry) preservation; alsothe holotype did not have a rudimentary prepollex. The latter might be because ofimmaturity (as revealed by the smaller size [39 mm SVL] and coloration [see below]) and/or that the holotype was a female. For additional information about the morphologicalvariation in this species see Lutz (1973).In the original description, the coloration is described as: dorsal surfaces light creamy-brown. A dark brown triangular fleck between eyes, opening directed anteriorly; alongitudinal fleck on each shoulder and some irregular, less distinct flecks on posteriordorsum; limbs barred; posterior surfaces of thighs with vividly dark and light flecking.Some faded flecks on groin; belly white, without flecks. The description of the colorationresembles immature Hypsiboas raniceps. Juveniles are mostly pale green with an invertedtriangular mark from the interorbital region to the middle of the dorsum (pers. obs.).During further development, this mark tends to reduce progressively while the remainingcoloration becomes brownish.AcknowledgementsJMP’s work in Bolivia was financed by a grant of the Mutis programme of the MAE-AECI(Spain).
