Ikakogi is a behaviorally and morphologically intriguing genus of glassfrog. Using tadpole morphology, vocalizations, and DNA, a new species is described from the Sierra Nevada de Santa Marta (SNSM), an isolated mountain range in northern Colombia. The new taxon is the second known species of the genus Ikakogi and is morphologically identical to I . tayrona (except for some larval characters) but differs by its genetic distance (14.8% in mitochondrial encoded cytochrome b MT-CYB ; ca. 371 bp) and by the dominant frequency of its advertisement call (2928–3273 Hz in contrast to 2650–2870 Hz in I . tayrona ). They also differ in the number of lateral buccal floor papillae, and the position of the buccal roof arena papillae. Additionally, the new species is differentiated from all other species of Centrolenidae by the following traits: tympanum visible, vomerine teeth absent, humeral spines present in adult males, bones in life white with pale green in epiphyses, minute punctuations present on green skin dorsum, and flanks with lateral row of small, enameled dots that extend from below eye to just posterior to arm insertion. We describe the external and internal larval morphology of the new species and we redescribe the larval morphology of Ikakogi tayrona on the basis of field collected specimens representing several stages of development from early to late metamorphosis. We discuss the relevance of larval morphology for the taxonomy and systematics of Ikakogi and other centrolenid genera. Finally, we document intraspecific larval variation in meristic characters and ontogenetic changes in eye size, coloration, and labial tooth-rows formulas, and compare tadpoles of related species. Ikakogi tayrona has been proposed as the sister taxon of all other Centrolenidae; our observations and new species description offers insights about the ancestral character-states of adults, egg clutches, and larval features in this lineage of frogs.

Based on a molecular phylogeny, a new phylogenetic taxonomy that is compatible with both the International Code of Zoological Nomenclature (ICZN) and the PhyloCode is proposed for Glassfrogs and their sister taxon, Allophryne ruthveni. The arrangement presented herein emphasizes the recognition of clades having (i) significant statistical support and congruence among phylogenetic estimation methods (i.e., parsimony, maximum likelihood, and Bayesian inference criteria), (ii) congruence among genetic markers, and (iii) morphological and/or behavioral distinctiveness. Also, when previously recognized groups are recovered as monophyletic or nearly monophyletic, we propose taxa that minimize the number of name changes required to make these groups monophyletic, preserving the names and contents of previous classifications (i.e., nomenclatural stability). The evolutionary proximity of Centrolenidae and Allophrynidae is recognized by combining these families into an unraked taxon, Allocentroleniae—a proposal that maintains the traditional names and species contents of Centrolenidae and Allophrynidae. We arrange centrolenid diversity in two subfamilies: Centroleninae and Hyalinobatrachinae. Within Centroleninae, the diagnosis and species content of the genera Centrolene, Cochranella, and Nymphargus are modified; Teratohyla is resurrected and modified, and Chimerella, Espadarana, Rulyrana, Sachatamia, and Vitreorana are proposed as new genera. The other subfamily, Hyalinobatrachinae, contains the new genus Celsiella and a modified Hyalinobatrachium that fully corresponds to the former fleischmanni Group. Additionally, the genus Ikakogi is described. Ikakogi could not be assigned with confidence to either subfamily and it is placed as incertae sedis in Centrolenidae. The data at hand suggest that Ikakogi tayrona is a lineage as old as the subfamilies Hyalinobatrachinae and Centroleninae. The revised taxonomy differs markedly from previous arrangements, which were based on phenetics and few morphological characters. Most of the genera defined herein are confined to distinct biogeographic regions, highlighting the importance of geography in the speciation of Glassfrogs. The principal limitation of this proposal is that it is based on an incomplete sampling of taxa (54% of the recognized Glassfrogs). Although diagnoses are based on phenotypic traits, there are several cases (16% of all species) in which the allocation of species is ambiguous because of morphological homoplasy and the lack of molecular data. Finally, in an attempt to facilitate species identification, comparison, and generic placement, we provide photographs for most (~ 96%) of the recognized centrolenid species.

“…The recent discovery of new species and new country records (e.g. Velásquez-Álvarez et al 2007;Rada et al 2017aRada et al , 2017bRada et al , 2019Thompson et al 2018; this work) exemplify this scenario. Thus, similar results are expected as fieldwork continues in poorly explored areas, such as the Andean/Amazonian and Andean/Chocoan forests.…”

“…Although Lynch et al (1997) estimated that only 10% of the centrolenid diversity in Colombia remained to be discovered, the number of species known to occur in the country has increased to 79 at present (Frost 2020). However, this number remains uncertain because taxonomic studies and fieldwork often result in names being resurrected or placed in synonym, the description of new taxa (Velásquez-Álvarez et al 2007;Guayasamin et al 2008;Rada et al 2017aRada et al , 2017bRada et al , 2019 and distribution extensions of species, including new country records (Malambo et al 2013(Malambo et al , 2017Molina-Zuluaga et al 2017;Thompson et al 2018).…”

The Neotropical amphibian family Centrolenidae currently includes 156 named species of nocturnal anurans commonly known as glassfrogs. With 79 species, Colombia is the country with the highest diversity of centrolenids. However, the number of species known to occur in the country remains uncertain because research often results in names being resurrected or placed in synonymy, the description of new taxa, and range extensions of species, including new country records. Based on field trips and assess of additional specimens, herein we report new distribution data for centrolenids species in Colombia. These data include six new distribution records for: (Cochranella granulosa, Nymphargus balionotus, N. chami, N. grandisonae, Hyalinobatrachium mondolfii, and H. pellucidum). Records of C. granulosa and H. pellucidum are the first records of these species from Colombia. Thus, our study increases to 81 the numbers of glassfrogs for this country. Because most Hyalinobatrachium have a conservative morphology, making species identification problematic when only based on external traits, we sequenced a fragment of the mitochondrial gene 16S to confirm species identities within a phylogenetic context. We discuss the taxonomic implications of our results for the recognition of species and populations that are morphologically similar to H. talamancae.
