Resumo: | Studies with the subfamily Eumeninae, have been expanded in the last years, mainly with phylogenetic studies, investigating the relationship between species of some genera, taxonomic revision works and descriptions of new species. However, the taxonomy and relationship of many Eumeninae lineages still remain unclear. In this sense, a study is needed to investigate the phylogeny of the genera Minixi Giordani Soika, 1978 and Alphamenes Van der Vecht, 1977, which will bring important contributions to a phylogenetic classification for the subfamily. The main goal of this work was to perform a systematic study of the two genera mentioned above, using cladistic methods and morphological data; to test the monophyly of the genera and to carry out necessary taxonomic procedures. The methodology used was to examine the external morphology of dry preserved specimens borrowed from collections of museums and institutions from Brazil and abroad, and male genitalia. Later, the construction of an array of characters and cladistic analyses were carried out. All recognized species of Alphamenes and Minixi were included as an internal group. Relatively related species belonging to the genus Pachymenes de Saussure, 1852 were also included. For the rooting of the tree Monobia angulosa de Saussure, 1852 was used as external group. Heuristic searches for the most parsimonious cladograms were performed using the implicit weighing of the characters and the support for the branches was estimated by symmetrical re-sampling. Alphamenes and Minixi were recovered as monophyletic groups, corroborating previous hypotheses with fewer species. Three large clades were analyzed for the species of the genus, with the following phylogenetic relationships: ((Pachymenes + Alphamenes) + Minixi)). Internal relations within the two genera were elucidated and almost fully resolved. However, there is still a need for more in-depth studies, especially regarding the relationships between Minixi lineages. The delimitation of females for the genus Alphamenes is imprecise and confusing, due to the morphological homogeneity presented among species. In this sense, another important point of this work was the delimitation of some females of Alphamenes: A. campanulatus, A. usitatus and A. insignis. Two males of Minixi are described for the first time. In addition, it is proposed in this work an identification key for the species of Alphamenes, with the inclusion of females, and the synonymizat ion of a subspecies of Alphamenes. |

No entanto, a taxonomia e o relacionamento de muitas linhagens de Eumeninae ainda permanecem não esclarecidas. Nesse sentido, se faz necessário um estudo sobre a filogenia dos gêneros Minixi Giordani Soika, 1978 e Alphamenes Van der Vecht, 1977, que trará importantes contribuições para uma classificação filogenética para a subfamília. Além da ampliação do conhecimento destes táxons cuja distribuição é em grande parte Neotropical. Este trabalho teve por objetivo realizar um estudo sistemático dos dois gêneros citados acima, através de métodos cladísticos, utilizando dados morfológicos; testar a monofilia dos gêneros e realizar procedimentos taxonômicos que forem necessários. A metodologia utilizada foi exame da morfologia externa dos espécimes emprestados de coleções de museus e intituições do Brasil e exterior, preservados a seco e genitália masculina condicionada em glicerina. Posteriomente foi realizada a contrução de uma matriz de caracteres e análises cladísticas. Foram incluídas como grupo interno todas as espécies reconhecidas de Alphamenes e Minixi, além de espécies proximamente relacionadas pertencentes ao gênero Pachymenes de Saussure, 1852 foram também incluídas. Para o enraizamento da árvore foi utilizado como grupo externo Monobia angulosa de Saussure, 1852. Buscas heurísticas pelos cladogramas mais parcimoniosos foram realizadas utilizando a pesagem implícita dos caracteres e o suporte para os ramos foi estimado pela reamostragem simétrica. Alphamenes e Minixi foram neste trabalho recuperados como agrupamentos monofiléticos, corroborando hipóteses anteriores com menor número de espécies. Foram estabelecidos nesta análise três grandes clados para as espécies dos gêneros, com as seguintes relações filogenéticas: ((Pachymenes + Alphamenes) + Minixi)). As relações internas dentro dos dois gêneros foram elucidadas e a maioria esclarecidas. No entanto ainda há a necessidade de estudos mais profundos, principalmente com relação aos relacionamentos entre as linhagens de Minixi. A delimitação de fêmeas para o gênero Alphamenes é imprecisa e confusa, devido a homogeneidade morfológica apresentada entre as espécies. Nesse sentido outro ponto importante deste trabalho foi a delimitação de algumas fêmeas de Alphamenes: A. campanulatus, A. usitatus e A. insignis. Dois machos de Minixi são descritos pela primeira vez e a sinonimização de uma subespécie de Alphamenes é apresentada. Além disso, uma chave de identificação para as espécies de Alphamenes, com a inclusão de fêmeas, é proposta.Universidade Federal de LavrasPrograma de Pós-Graduação em EntomologiaUFLAbrasilDepartamento de EntomologiaHermes, Marcel GustavoHermes, Marcel GustavoHaseyama, Kirstern LicaMorales, Mírian NunesOliveira, Letícia Aparecida de2017-04-04T17:04:59Z2017-04-04T17:04:59Z2017-04-032017-02-24info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfOLIVEIRA, L.
