Taxonomic orthodoxy dictates that all specimens of this widespread taxon represent a single morphospecies. We analyzed a dataset of previously published and newly generated sequences of the mitochondrial COI gene of the L. bulla complex to examine cryptic diversity in the taxon. We undertook phylogenetic analyses and applied 3 methods of species delimitation (ABGD, PTP and GMYC) to identify cryptic species within L. bulla. Our results revealed the existence of 13 cryptic species based on the agreement of the different delimitation methods. Genetic distances between the 13 cryptic species ranged from 4.6 to 16.8%. We found a barcoding gap where the intraspecific divergences (within cryptic species) were smaller than interspecific divergences (among cryptic species), thus supporting the 13 cryptic species delimited by the species delineation methods as independent entities. Our work reveals high levels of cryptic diversity in L. bulla and highlights the need to further studies to resolve the taxonomic status of these cryptic species (and genetic lineages). 2020 artículo científico 1870-3453 https://www.redalyc.org/articulo.oa?id=42571632002 https://www.redalyc.org/journal/425/42571632002/ https://www.redalyc.org/journal/425/42571632002/html/ https://www.redalyc.org/journal/425/42571632002/42571632002.epub https://www.redalyc.org/journal/425/42571632002/movil 10.22201/ib.20078706e.2020.91.3116 en http://www.redalyc.org/revista.oa?id=425 Revista Mexicana de Biodiversidad application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Biodiversidad (México) Vol.91 |
