摘要

Certain taxonomic groups appear superficially very similar to each other, which may disguise hidden diversity. In such cases, vocalizations can be important distinguishing characteristics, particularly for anurans. One such group of anurans is the Craugastor podiciferus species group, for which vocalizations of many species have not been previously published. Consequently, our aim was to quantitatively describe for the first time, the vocalizations of three species from this group: Craugastor gabbi (Gabb’s Flesh-bellied Frog), C. aff. persimilis (Similar Flesh-bellied Frog), and C. underwoodi (Underwood’s Flesh-bellied Frog), and to describe calls of two other species, C. podiciferus (Piglet Flesh-bellied Frog), and C. stejnegerianus (Stejneger’s Flesh-bellied Frog), from additional localities. We recorded 510 calls from 29 individuals at five localities in Costa Rica. We confirmed that all five species have a tonal call consisting of a short (0.10–0.79 s), single, squeak-like note with a dominant frequency ranging from 2,483.5–6,175.7 Hz. We further confirmed that C. podiciferus produces a pulsed call, and document them for C. gabbi, C. aff. persimilis, and C. underwoodi. Lastly, we present several miscellaneous call types (up-sweep, down-sweep, pulsatile-harmonic, and chain-chirp). Our quantitative analyses revealed differences in taxonomically important call variables such as call duration and dominant frequency. Formal descriptions of frog vocalizations are important in facilitating species identification in the field and may contribute to the recognition of hidden species diversity in morphologically similar species groups.
