“…Oedipina villamizariorum and O. ecuatoriana are likely rare species, with only one specimen for each species ever collected. Habitat change, fragmentation, and loss in the region is extensive and continues due to the expansion of the agricultural frontier and mining (Guayasamin et al, 2019;Roy et al, 2018;Sierra, 2013). Intensive herpetological surveys across the provinces of Esmeraldas, Imbabura, and Carchi have been conducted (MECN, 2013;Yánez-Muñoz et al, 2010;Yánez-Muñoz et al, 2018;Yánez-Muñoz et al, 2020) however, no Oedipina have been recorded.…”

We describe two new species of salamanders of the genus Oedipina, subgenus Oedopinola, from two localities on the northwestern foothills of Ecuador, at elevations between 921 and 1,067 m. These are the southernmost members of the genus. We examined different museum collections and we found just three specimens of Oedipina from Ecuador, obtained throughout the history of herpetological collections in the country. We identify two of the three specimens as new species, but refrain from assigning a specific identity to the third, pending further study. Oedipina villamizariorum sp. n. is a medium-sized member of the genus, with a narrow, relatively pointed head and blunt snout; dorsolaterally oriented eyes, moderate in size; and digits that are moderately long and having pointed tips. Oedipina ecuatoriana sp. n., somewhat larger, has a narrow head and broadly rounded snout; this new species differs from all known Oedipina by the distinctive presence of paired prefrontal bones and a reduced phalangeal formula: 0-0-1-0; 0-1-2-1-1. We provide detailed descriptions of the osteology of both new species. Finally, we present a phylogenetic hypothesis for the genus, including one of the two new species, based on partial sequences of mitochondrial DNA.

“…Ecuadorian biodiversity is still not fully documented or understood. General richness patterns seem to be extensions of those seen in the surrounding biodiversity giants, Colombia and Peru, yet recent results indicate that local geodiversity and microclimates may be acting as biological lineage pumps at different geographic scales (e.g., Hutter et al 2013, Polato et al 2018, Sornoza-Molina et al 2018, Guayasamin et al 2019.…”

Executive Summary. Alexander von Humboldt conducted his best-known work on the slopes of the Ecuadorian Andes. He did this by applying his own characteristic brand of multidisciplinary scientific approach. This consisted of thorough data collection while synthesizing and visualizing the data in innovative formats. Also important for his scientific success in South America was his collaborative network that helped him to identify specimens and formulate his transformative scientific thoughts. It is no surprise that Humboldt was captivated by Ecuador, as it is one of the most biodiverse places in the world, and this astounding diversity was formed in an intricate, dynamic geological and climatological setting. As of yet, this biodiversity is far from being fully documented and the processes that generated it are still poorly understood. The IBS meeting in Quito 1 and the Second Latin American Congress of Biogeography will form the perfect platform to both commemorate Humboldt while addressing current and unresolved matters concerning the biodiversity of Ecuador and South America at large.

“…However, species identification within Hyalinobatrachium is often problematic due to subtle morphological differences among taxa. This situation is evidenced by the confusing taxonomic status of several species (see Castroviejo-Fisher et al 2008, 2011a, 2011bGuayasamin et al 2008Guayasamin et al , 2017Guayasamin et al , 2019Kok & Castroviejo-Fisher 2008;Chávez et al 2019;Mendoza-Henao et al 2020). Difficulties in identifying species of Hyalinobathrachium are compounded by the modification of key taxonomic characteristics as an artifact of preservation (e.g.…”

Therefore, additional data from vocalizations and DNA sequences provide useful characters for discriminating among species of this genus.…”

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.
