| Abstract | |
The genus Ananteris Thorell, 1891, includes 85 cryptic species, distributed primarily in the Neotropical region. In recent years, there has been a considerable increase in the number of species of the genus, and some of these studies having contributed with taxonomically useful morphological information. Nevertheless, the lack of organization in the taxonomy of Ananteris remains worrisome, revealing the need for the revision of a representative number of species this taxon, and especially phylogenetic studies. Currently, there are no phylogenetic hypotheses including all species of the genus. Here, we performed a cladistic analysis including an ingroup of 54 species of Ananteris and nine outgroup species belonging to other Buthidae genera. The data matrix comprises 82 morphological characters and the analyses were conducted with TNT 1.5 software under the parsimony criterion using implicit weighing, with different concavity values. The results showed that Ananteris is a monophyletic group supported by ten unique synapomorphies. The genus is divided into two major clades: A and B. The genus Ananteroides emerged as sister group of Ananteris, this relationship supported by six synapomorphies. Based on our results, we updated the diagnosis of Ananteris, and proposed two new synonyms: Ananteris leilae Lourenço, 1999 as a junior synonym of Anateris platnicki Lourenço, 1993 and Ananteris otavianoi Lira, Pordeus & Albuquerque, 2017 as a junior synonym of Ananteris mauryi Lourenço, 1982. Thus, the present study is the most complete phylogenetic analysis of the genus, proposing for the first time a relationship hypothesis between the species of Ananteris (AU) | |
