Abstract

ABSTRACT The genus Luteostriata Carbayo, 2010, currently comprises 10 species distributed in southeastern and southern Brazil. Species of this genus represent a taxonomic challenge because many have very similar external and internal features. Some species were described based on specimens from many localities using anatomical and histological features without phylogenetical analyses, such as Luteostriata ernesti, known from various localities in southeastern and southern Brazil. We conducted an integrative taxonomic approach of southeastern and southern specimens of L. ernesti, performing morphological analyses and using two molecular markers. Our results reveal that there are at least two clades (southeastern and southern) under the designation L. ernesti, and phylogenetic analyses show that they are not sister groups. Thus, we took the taxonomic decision to describe a new species, Luteostriata dissimilis Iturralde & Leal-Zanchet, sp. nov., which is split off from L. ernesti based on specimens of the southern clade. The phylogenetic analyses suggest a close relationship between Luteostriata dissimilis and Luteostriata muelleri and indicate that Luteostriata ernesti is more closely related to Luteostriata caissara. Our results also indicate that species delineation may be the first approach to understanding the diversity and distribution of species in this genus and that a complete taxonomic revision of Luteostriata species is necessary. http://www.zoobank.org/urn:lsid:zoobank.org:act:F83EE656-A491-493D-9F25-97413097D007

期刊介绍： There is still a far from complete understanding of the complex ecosystems in the Neotropics, although they have been studied since the first expeditions of the old world naturalists Marcgrave, Humboldt, Spix, Darwin, Bates and Müller. The aims and scope of the Journal are, besides taxonomic and zoogeographic surveys, analyses of animal communities and their relationship with biotic and abiotic environmental conditions. This includes the fauna of both terrestrial and fresh water ecosystems in the Neotropics. Contributions that represent original research and mini-reviews are welcome. Manuscripts presenting just checklists and new geographic records are not considered for publication. If manuscripts do not meet the requirements of the journal, the editors reserve the right to reject manuscripts on submission or to ask for revisions prior to formal peer review.
