Sistemática de Simothraulopsis Demoulin, 1966 (Ephemeroptera: Leptophlebiidae: Atalophlebiinae)

The genus Simothraulopsis Demoulin belongs to the family Leptophlebiidae and only occurs in the Neotropical region. Currently it is represented by five species, but only three of these have the nymph described. In general, studies of the genus are spotty and provide little information on the biology...

Currently it is represented by five species, but only three of these have the nymph described. In general, studies of the genus are spotty and provide little information on the biology of the different species and their distributions. In the present study we review current knowledge of Simothraulopsis and, based on specimens from different regions of Brazil, we add new taxonomic and biological information to this genus. A phylogenetic study was undertaken based on morphological data with the specific objective of evaluating the monophyly of Simothraulopsis and interespecific relationships within the genus. For this purpose, 46 characters related to external morphology of adults and nymphs were identified. The characters were evaluated by Fitch parsimony with equal weights and also successive weightings, and the resulting topologies were rooted a posteriori with an outgroup taxon. The analysis resulted in a single most-parsimonious tree and confirmed the monophyly of Simothraulopsis (supported by four synapomophies) and indicated the genus Homothraulus Demoulin, 1955 as the sister group. As a taxonomic result, four new species are described, increasing by 80% the number of representatives of the genus. Nymphs of Simothraulopsis diamantinensis Mariano, 2010 and Simothraulopsis janae Mariano, 2010 were described and the geographical distribution of the genus has been extended to several regions of Brazil. Previously, three of the five described species had only been recorded in their type localities. Detailed descriptions, including illustrations of structures not normally used in taxonomic studies on the family, diagnoses, biological comments and taxonomic keys for larvae and adults are integrated into the knowledge regarding the genus. Simothraulopsis Demoulin, 1960 pertence à Leptophlebiidae e possui ocorrência somente para a região Neotropical. Atualmente é representado por cinco espécies, sendo que apenas três delas possuem as ninfas descritas. No geral, estudos com o gênero são apenas pontuais e carecem de informação, principalmente sobre a biologia e distribuição das espécies. Neste trabalho, a partir de material coletado em várias regiões do Brasil, apresentamos uma revisão do conhecimento sobre Simothraulopsis, adicionando novas informações taxonômicas e biológicas sobre o gênero. Um estudo filogenético, baseado em dados morfológicos, foi realizado visando avaliar o monofiletismo e as relações interespecíficas de Simothraulopsis. Com este propósito, foram levantados 46 caracteres dos adultos e ninfas referentes à morfologia externa. Os caracteres foram avaliados por meio da parcimônia de Fitch com pesos iguais e pesagens sucessivas, e as topologias obtidas foram enraizadas a posteriori de acordo com a posição de um grupo externo. A análise resultou em uma única árvore mais parcimoniosa e confirmou o monofiletismo de Simothraulopsis, sustentadado por quatro sinapomorfias, bem como a sua relação como grupo-irmão de Homothraulus Demoulin, 1955. Como resultado taxonômico, quatro novas espécies foram descritas, incrementando em 80% o número de representantes para o gênero. As ninfas de Simothraulopsis diamantinensis Mariano, 2010 e Simothraulopsis janae Mariano, 2010 foram descritas e a distribuição geográfica do gênero foi expandida para diversas regiões do Brasil. Anteriormente, três, das cinco espécies do gênero, eram registradas apenas para suas localidades-tipo. Descrições detalhadas, incluindo ilustrações de estruturas não utilizadas usualmente em estudos taxonômicos sobre a família, diagnoses, comentários biológicos e chaves para identificar ninfas e adultos do gênero integram o conhecimento relativo ao gênero. 2020-02-17T20:21:30Z 2020-02-17T20:21:30Z 2014-03-11 Dissertação https://repositorio.inpa.gov.br/handle/1/12397 http://lattes.cnpq.br/3880118795645876 por Attribution-NonCommercial-NoDerivs 3.0 Brazil http://creativecommons.org/licenses/by-nc-nd/3.0/br/ application/pdf Instituto Nacional de Pesquisas da Amazônia - INPA Entomologia
