“…Sequestration as a defensive strategy appears to have evolved independently in four lineages of dendrobatids, with 97 dendrobatid species in 11 genera known or believed (based on coloration and phylogeny) to employ alkaloid‐based defenses (Grant et al. , ; Saporito et al. ; Santos et al.…”

Amézquita et al. (2017) recently concluded that species of the Allobates femoralis group are toxic to mice at levels equivalent to syntopic alkaloid-containing poison frogs, which they attributed to the presence of alkaloids in skin secretions. However, the chemical composition of skin secretions was not analyzed, and here we present additional data supporting the absence of alkaloids in skin secretions of the Allobates femoralis group. Instead, we suggest the observed toxicity was caused by the anesthetic benzocaine, which was applied to the buccal cavity to euthanize frogs prior to skin removal. We show that orally administered benzocaine is rapidly incorporated into the skin of species that sequester and do not sequester alkaloids, which casts doubt on the conclusion that Allobates femoralis group skin secretions are toxic and makes the results of experiments with alkaloid-containing species of Adelphobates and Ameerega uninterpretable. To prevent experimental errors and misinterpretations in studies of amphibian chemical defense, we encourage researchers to test the chemical composition of samples prior to experimentation, include all necessary controls to detect false positives, conduct small pilot studies for new methods, and consider the limitations of particular methods and their ability to address the intended research questions.

“…No species of the sister group of Dendrobatidae, Aromobatidae, is known to possess alkaloid‐based chemical defenses (Grant et al. , ), despite the astonishing resemblance in coloration and skin texture of Allobates femoralis group species to several alkaloid‐containing species of the dendrobatid genus Ameerega .

Redescription of the tadpoles of Epipedobates narinensis and E. boulengeri (Anura: Dendrobatidae). The larval morphology of poison frogs (Dendrobatoidea) has contributed to an understanding of the phylogenetic relationships within the superfamily. Nevertheless, our knowledge of larval morphology is incomplete. The larvae of the dendrobatids, and are redescribed, diagnosed, and differentiated from three congeners, as well as sympatric dendrobatoids and closely related genera. Three larval developmental phases are described-viz., (1) back-riding tadpoles, (2) free-swimming tadpoles, and (3) metamorphosing tadpoles. Each larval phase is characterized by ontogenetic changes in external morphology, and there is also morphological variation within each developmental phase. Ontogenetic morphological changes are the most marked in back-riding and metamorphosing phases. The external features of free-swimming tadpoles do not change abruptly, but ontogenetic changes occur in the marginal papillae, stitches of the lateral line system, and tail coloration. Four features that have not been considered previously distinguish species-groups and/or generamoderate A-2 gap; presence of shelf on back of the upper jaw sheath [UJS]; moderate notch on mid-UJS; and nostril size; these characters are putative synapomorphies of Metamorphosing tadpoles have some adult features, such as the color Keywords: A-2 gap size, anteroventral coloration, Colostethinae, larval characters, nostril, ontogenetic variation. 156Phyllomedusa -16(2), December 2017 ResumenRedescripción de los renacuajos de Epipedobates narinensis y E. boulengeri (Anura: Dendrobatidae).La morfología larvaria de las ranas venenosas (Dendrobatoidea) ha contribuido en el entendimiento de las relaciones de parentesco dentro de la superfamilia.
