“…The eastern slopes of the Peruvian Andes are one of the regions with the greatest diversity of flora and fauna [1]. During the last few years, many species of plants and animals from the Peruvian Andes have been discovered (e.g., [2,3]). In particular, researchers have discovered many species of lizards of the family Gymnophthalmidae in poorly explored regions [4][5][6][7][8][9].…”

The family Gymnophthalmidae is one of the most speciose lineages of lizards in the Neotropical region. Despite recent phylogenetic studies, the species diversity of this family is unknown and thus, its phylogenetic relationships remain unclear and its taxonomy unstable. We analyzed four mitochondrial (12S, 16S, Cytb, ND4) and one nuclear (c-mos) DNA sequences of Pholidobolus anomalus, Cercosaura manicata boliviana and Cercosaura sp., using the maximum likelihood method to give insights into the phylogenetic relationships of these taxa within Cercosaurinae. Our results suggest that Pholidolus anomalus is nested within the clade of Cercosaura spp., that material we collected near Oxapampa belongs to a new species of Cercosaura, and that lizards identified as Cercosaura manicata boliviana belong to a separate lineage, possibly a new genus. We assign Pholidobolus anomalus to Cercosaura, redescribe the species, and designate a neotype to replace the lost holotype. In addition, we describe the new species of Cercosaura, and comment about the taxonomic status of “Cercosaura manicata boliviana”incertae sedis.

“…Simultaneously, at the regional level, it is a region with steep and rugged topography, and highly variable geology and climate that results in a landscape of varied and isolated vegetation types (Mandl et al 2010). The region also has exceptional fern diversity (Kessler and Lehnert 2009a), with many new species being continuously described (e.g., Lehnert and Tejedor 2016;Tejedor and Calatayud 2017). This also applies to the grammitid ferns, a monophyletic lineage of mostly epiphytic ferns belonging to the family Polypodiaceae (Schneider et al 2004;Ranker et al 2004;Sundue et al 2015), which includes some 400 species in the Neotropics and 500 species in the Palaeotropics (Bauret et al 2017).…”

Ascogrammitis lehnertii (Polypodiaceae): A New and Dominant Understory-Species from a Diverse Community of Grammitid Ferns in the Andes of Ecuador

In the scope of pantropical studies aimed at understanding how the diversity of grammitid ferns (Polypodiaceae) has evolved and is maintained, we studied a diverse grammitid community in treeline elfin forests in eight study plots of 400 m2 each at 3200 m on Cerro Toledo, Loja, southern Ecuador.Werecorded a total of 7986 individuals of 16 grammitid species. Ascogrammitis lehnertii is here described as a newspecies.We also recorded Mycopteris leucosticta, a species previously believed to be restricted to the Choc´o region of Ecuador. We found that the grammitid species were segregated by habitat into trunk-base and trunk specialists, which suggests that species coexistence in these diverse epiphytic communities is at least partly linked to habitat segregation. Ascogrammitis lehnertii and M. leucosticta were the second and third most abundant species, respectively, and both were mostly trunkbase species. The new species A. lehnertii differs from its congeners by the combination of its relatively broad lamina, (2-)3-4 cmwide, fertile leaves bearing 2mmlong reddish setae in and near the sori, and by bearing proliferous roots from which new plants emerge. Phylogenetic analyses of atpß, rbcL, rps4, trnG-trnR, andtrnL-trnFDNAmolecular sequences, usingmaximum likelihood, place A. lehnertii as sister to A. cuencana with strong support. Despite previous intensive collection efforts in Loja for the past 30 yr, all but one of the collections of this new species were made in the last three years. The discovery of A. lehnertii and the new record of M. leucosticta highlight the patchy distribution of some species in the Andes and the value of surveying.
