Abstract

Abstract We use integrative taxonomy to formally describe a candidate species of nurse frog of the genus Allobates from southwestern Brazilian Amazonia. The new species nests within a clade that has been defined historically as A. gasconi, but it has an 8.8–11.0% genetic distance for 16S to samples from the type locality of A. gasconi. The new species differs from congeners mainly by males having a translucent white throat and vocal sac; advertisement calls with a duration of 42–60 ms, two notes separated by an inter-note interval of 8–23 ms, and a dominant frequency of 4,953–6,331 Hz; and exotrophic tadpoles with 2 pyramidal papillae on each end of the upper lip and 10–13 pyramidal and cylindrical papillae surrounding the lower lip. Phylogenetic analyses based on mitochondrial DNA suggest that A. gasconi sensu lato as defined previously represents a complex of as many as seven species, corroborating studies that have shown high levels of cryptic diversity within Allobates.

18. First DNA barcode efficiency assessment for an important ingredient in the Amazonian ayahuasca tea: mariri/jagube, Banisteriopsis (Malpighiaceae).

Abstract

Mariri or jagube (Banisteriopsis C. B. Rob.) is a vine of the Malpighiaceae family and is naturally found in the Brazilian Amazon. It is also an important ingredient of ayahuasca tea, which is used by some traditional, indigenous people and religious groups of Amazonian origin. Via DNA barcodes, this study aimed to evaluate the efficiency of six markers to access genetic diversity and use them in the identification of either ethnovarieties or species of Banisteriopsis used in the preparation of "ayahuasca" in the Amazon. The efficiency of three plastid genes (matK/trnK, ndhF, and rcbL) and three nuclear markers (MP3 and yage5 isolated in the present study and ITS—Internal Transcribed Spacer) were tested. For these six markers, a total of 4792 base pairs were sequenced. The plastid markers revealed that all the samples analyzed belong to the genus Banisteriopsis; however, they presented the lowest indices of genetic diversity and were not efficient for use in the identification of ethnovarieties. Nuclear DNA markers showed the highest levels of genetic diversity. The ITS showed the highest values of genetic distances between the identified lineages. This study demonstrates that the use of ITS for DNA barcoding was more efficient since the identified lineages showed correspondence with the ethnovarieties of Banisteriopsis spp. used in the preparation of ayahuasca. As such, we encourage new integrative studies like this one, which combines modern approaches and traditional knowledge, to contribute to the maintenance of traditional knowledge as well as the conservation of species.
