“…The utility of mitochondrial genes, especially 16S, to uncover population structure and cryptic species has a long history in amphibian studies and has been the most widely used to delimit species ( Fouquet et al, 2007 ; Funk, Caminer & Ron, 2012 ; Cryer et al, 2019 ; Páez & Ron, 2019 ; Guayasamin et al, 2020 ; Sánchez-Nivicela et al, 2021 ); moreover, because of the longer coalescence times of nuclear genes (approximately four times that of mtDNA), studies on closely related taxa heavily rely on fast-evolving genes ( Avise, 2000 ; Vences et al, 2005 ; Zink & Barrowclough, 2008 ).…”

Background Pristimantis is the most diverse genus of terrestrial frogs. Historically, it has been divided into several phenetic groups in order to facilitate species identification. However, in light of phylogenetic analysis, many of these groups have been shown to be non-monophyletic, denoting a high degree of morphological convergence and limited number of diagnostic traits. In this study, we focus on the Pristimantis myersi group, an assemblage of small rainfrogs distributed throughout the Andes of Ecuador and Colombia, whose external morphology is highly conserved, and its species diversity and evolutionary relationships largely unknown. Methods We inferred a new phylogenetic hypothesis for the frog genus Pristimantis, including all available sequences of the mtDNA 16S rRNA, as well as new DNA sequences from 175 specimens. Our sampling included 19 of the 24 species currently recognized as part of the Pristimantis myersi group. Results Our new evolutionary hypothesis recovered the P. myersi group as non-monophyletic and composed of 16 species. Therefore, we exclude P. albujai, P. bicantus, P. sambalan, and P. nelsongalloi in order to preserve the monophyly of the group. We discovered at least eight candidate species, most of them hidden under the names of P. leoni, P. hectus, P. festae, P. gladiator, and P. ocreatus. Discussion Our results reveal the occurrence of a high level of cryptic diversity to the species level within the P. myersi group and highlight the need to redefine some of its species and reassess their conservation status. We suggest that the conservation status of six species within the group need to be re-evaluated because they exhibit smaller distributions than previously thought; these species are: P. festae, P. gladiator, P. hectus, P. leoni, P. ocreatus, and P. pyrrhomerus. Finally, given that the Pristimantis myersi group, as defined in this work, is monophyletic and morphologically diagnosable, and that Trachyphrynus is an available name for the clade containing P. myersi, we implement Trachyphrynus as a formal subgenus name for the Pristimantis myersi group.

“…Despite its small size, Ecuador harbors several types of ecosystems in the Tropical Andes region, which have been recognized as hotspots of amphibian diversity [ 3 ]. Their distinctiveness is still far from completely known, numerous species being described during the recent years [ 5 – 8 ]. The city of Loja, the capital of Loja Province, is one of the largest cities from Southern Ecuador (with more than 250,000 inhabitants), and has two areas of high diversity in its vicinity: Parque Nacional Podocarpus and Abra de Zamora [ 7 , 9 ].…”

We describe a new species of rain frog of the genus Pristimantis from the city of Loja, Southern Ecuador, based on an integrative taxonomy approach, combining molecular, morphological and bioacoustics data. Pristimantis lojanus sp. nov. is a medium sized species of the phylogenetically strongly supported P. phoxocephalus group, and its sister species is P. torresi. The new species can be easily distinguished from its closest congeners and morphologically similar species (that also have acuminate snout with a fleshy keel) by its characteristic advertisement call and morphological features (dorsum finely tuberculate with scattered larger tubercles, flanks without longitudinal lateral folds, no markings in axilla, groin or on concealed limb surfaces, and bronze iris). Additionally, we describe the advertisement call of its sister species, P. torresi. Finally, we detail the current situation of the amphibian species present in the city of Loja and its surroundings.
