| Summary: | Family: Bufonidae This group of toads contains some of the most familiar anurans, including the cane toad (Rhinella marina; previously Bufo marinus) and the jambato (Atelopus ignescens). Most of them have a warty appearance and are diurnal, terrestrial, and have aquatic larvae (e.g., Rhinella, Atelopus), but others are nocturnal, arboreal, and undergo direct development (e.g., Osornophryne). Bufonids are found natively in all continents, except Australia (where it has been introduced) and Antarctica. The family Bufonidae contains 538 species (AmphibiaWeb 2009). The taxonomy of amphibians has undergone several recent changes and there is debate on which names should be used. For bufonids, we follow the general proposal by Frost et al. (2006), as modified by Chaparro et al. (2007). In YBS, there are two species of bufonids, Osornophryne guacamayo and Rhinella margaritifera (previously Bufo margaritifer). Osornophryne guacamayo (Plate 1). Described by Hoogmoed (1987). This species can be easily recognized by having a blackish dorsal coloration with, usually, two yellow-gray dorsolateral lines, which are not clearly differentiated from the rest of the dorsum; yellow venter with dark brown to black spots; dorsal skin of body and limbs with numerous tubercles of different sizes; limbs long and slender; fingers connected by a thick web; feet heavily webbed with Toe IV and V much longer than Toes I, II, and III; and by lacking parotoid glands and tympanum (Hoogmoed 1987). At YBS, SVL in adult females is 36.1–39.3 mm (n = 3) and 22.7 mm in one adult male. Osornophryne guacamayo has been found on leaves during the night (Table 1). Although most bufonids reproduce in water, O. guacamayo places its eggs on the ground, where they undergo direct development into froglets. At YBS, the only species that is likely to be confused with O. guacamayo is Rhinella margaritifera, which has a visible tympanum, parotoid glands, dorsolateral row of red tubercles (traits absent in O. guacamayo), and lacks conspicuous webbing among fingers ... |
