the phylogenetic relationships of the two winged south american Leptophlebiidae genera revisited with first description of the male imago of bessierus thomas amp orth insecta ephemeroptera
Zootaxa, 2019Co-Authors: Eduardo Dominguez, Maria Gabriela Cuezzo, Simon ClavierAbstract:: Four of the 43 genera of South American Leptophlebiidae are dipterous. A previous phylogenetic hypothesis supported that clade Askola+Hagenulopsis, and that Bessierus+Perissophlebiodes, are sister groups of the Farrodes complex. Adults of Bessierus and Perissophlebiodes were not known but posteriorly Perissophlebiodes male imago was described. Here, we describe the male imago of Bessierus for the first time. Both genera share, besides the absence of the hind wings, the asymmetrical fork of MA, symmetrical fork of MP, dissimilar tarsal claws, and forceps sockets fused. Along with the description of the imago, a new diagnosis for the genus Bessierus is presented, also updating the identification key with this new information. A new cladistics analysis is performed to test the stability of the proposed relationships of these four genera within Leptophlebiidae. We obtained a single cladistic hypothesis where the addition of Bessierus adult characters resulted in new synapomorphies for the (Bessierus, Perissophlebiodes) clade, and improved its clade statistical support. The fused forceps sockets resulted in a penisme/topic-synapomorphy/">synapomorphy uniting Bessierus, Perissophlebiodes and Simothraulopsis. As a result of this new analysis, the hypothesis of independent losses of the hind wings in the two dipterous groups studied is supported. The Farrodes lineage is not supported as proposed in previous studies, being restricted only to (Farrodes (Simothraulopsis, Homothraulus)) while the identity of "Perissophlebiodes lineage" is supported. The sister group relationship of Rondophlebia is not clearly defined.

morphology and evolution of the wing bullae in south american Leptophlebiidae ephemeroptera
Journal of Morphology, 2019Co-Authors: Eduardo Dominguez, Virginia AbdalaAbstract:: Insects were the first animals to take to the skies, and have been flying for over 320 million years. The order Ephemeroptera is, or at least is part of, the most early-diverging lineage of extant winged insects. The extant species present a very short adult life span, mainly dedicated to reproduction and dispersal of eggs. Mating and egg-laying behavior depend on flight. Wings are structures to fly and as such face a number of physical and physiological challenges. The convex curvature along the anterior-posterior axis of the wing generates a camber that must be carefully regulated. One of the most interesting ways of wing bending is provided by the bullae, which have been defined as short sections of flexible chitin, where the flexion lines cross veins. Although the bullae have been frequently used as penisme/topic-taxon/">taxonomic characters, there is no study focused on their morphology, although their prevalence on the wings of mayflies strongly suggests a role in flight. In order to identify evolutionary trends of these structures within Ephemeroptera, we constructed a matrix with comparative anatomy data of the bullae from whole mounts of the wings of 300 specimens belonging to 70 species of several mayfly families, as well as scanning microscopy samples of selected specimens. We also surveyed the number of bullae and their distribution in the wings of the different species within the South American Leptophlebiidae clade. We optimized the characters onto the latest published phylogeny for Leptophlebiidae.

Annales De Limnologie-international Journal of Limnology, 2015Co-Authors: Maria Del Carmen Zuniga, Eduardo Dominguez, Carlos Molineri, William CardonaAbstract:Gorgona National Natural Park comprises Gorgona and Gorgonilla Islands, located in the Colombian Pacific at 35 km from mainland. A large-scale study was conducted in Gorgona including samples from benthos and aereal nets and traps during five fieldworks. We here focus on the family Leptophlebiidae, describing two new species and giving data of four additional species. Terpides iguapoga sp. n. is described and illustrated from nymphs and adults, and can be characterized by the following characters, in the nymph: fore trochanter and femur with row of strong spine-like setae on inner margin, gills with blackish tracheae, posterolateral projections present on terga VI and VIII–IX; in the adult: upper portion of eyes orangeish white, forewing membrane hyaline tinged with penisme/topic-yellowish/">yellowish around crossveins and marginal intercalary veins, genitalia with penes abruptly narrowing on distal third. Thraulodes insular sp. n. is described from nymphs and adults and diagnosed as follows, in the nymph: abdominal gills with narrow lamellae, femora with black streak near apex; in the imago: forewing costal area basal to bulla without crossveins, a spot and a band on femora, terga II–VI translucent white, terga VII–X darker, posterior margin of subgenital plate triangular, penes spines short and robust. We give new geographic records for four additional species: Farrodes caribbianus , Farrodes roundsi , Hagenulopsis esmeralda and Hagenulopsis zunigae . Ecological data and distributional maps are provided. Leptophlebiidae presents a reduced diversity in relation to mainland; in general the species recorded show a geographic relation to the Chocoan-Caribbean and Andean mayfly faunas.

A new genus of the subtribe Hermanellina (Ephemeroptera: Leptophlebiidae: Atalophlebiinae) from Northern Brazil with accounts on the systematics of the group
Insect Systematics & Evolution, 2020Co-Authors: Frederico F. Salles, Rafael BoldriniAbstract:A new penisme/topic-taxon/">taxon of Hermanellonota or subtribe Hermanellina (Ephemeroptera: Leptophlebiidae: Atalophlebiinae) was found from Northern Brazil, in the limits of Pacaraima in Brazil and Santa Helena de Uairén in Venezuela. While nymphs of this penisme/topic-taxon/">taxon are similar to those of the genus Farrodes, the adults could not be assigned to any of the genera included in the group. In order to clarify the systematic relationship of this penisme/topic-taxon/">taxon and to provide a reliable hypothesis concerning its generic placement, we analyzed it using an available matrix from the literature and performed a new cladistic analysis. As a result we describe Rondophlebia rubra gen. nov. et sp. nov. sister to the Perissophlebiodes complex + Hermanella complex. Our analyses also shed new insights on the systematics of Hermanellonota.

phylogeny and classification of Leptophlebiidae ephemeroptera with an emphasis on neotropical fauna
Systematic Entomology, 2020Co-Authors: Marina Monjardim, Roberta Paresque, Frederico Falcão SallesAbstract:Mayflies from the family Leptophlebiidae are cosmopolitan and highly diverse morphologically; they are also the largest family in numbers of genera and the second in number of species in the order Ephemeroptera. In spite of their broad diversity and the efforts employed to understand the evolution of this group, the internal classification of Leptophlebiidae remains controversial at all levels. More recently, important changes have been incorporated into the systematics of the family, increasing the number of subfamilies (from two to six) and recognizing several tribes. We present a phylogeny of the family based on 153 taxa (53 genera) and two molecular markers, representing 1655 bp, and verify the penisme/topic-taxon/">taxonomic status of the subfamilies, tribes and complexes. Based on these results, the number of subfamilies has been increased from six to eight and one new tribes and two new subtribes have been added. In addition, new ranks are proposed and the concept of Atalophlebiinae revised, including genera with distributions in the Australasian and Neotropical regions.

systematics of simothraulopsis demoulin 1966 ephemeroptera Leptophlebiidae
Zootaxa, 2017Co-Authors: Jeane Marcelle Cavalcante Do Nascimento, Frederico Falcão Salles, Neusa HamadaAbstract:In the present paper, based on specimens from different regions of Brazil, we review the current knowledge of the Neotropical genus Simothraulopsis . A phylogenetic study was performed in order to address the relationships between all species and to test the monophyly of Simothraulopsis . For this purpose, 48 characters related to the external morphology of adults and nymphs were investigated. As a result, four new species are described; S. caliginosus sp.nov., S. dominguezi sp. nov., S. eurybasis sp. nov., S. inaequalis sp. nov. New penisme/topic-taxon/">taxonomic and biological information are added to this genus. Nymphs of S. diamantinensis Mariano, 2010 and S. janae Mariano, 2010 are described for the first time and several new distributional records for Brazil are provided. Additionally, keys for male imagos and nymphs of the genus are proposed. The phylogenetic analysis corroborated the monophyly of Simothraulopsis , however, the division in two subgenera as previously proposed was not recovered in our reconstruction.

Fauna of Leptophlebiidae Banks (Insecta: Ephemeroptera) on fragments of the Atlantic Forest from west region of Santa Catarina State, Brazil
Biota Neotropica, 2013Co-Authors: Erikcsen Augusto Raimundi, Frederico Falcão Salles, Gilza Maria De Souza-francoAbstract:The first studies of Leptophlebiidae in the Santa Catarina State, Southern Brazil, dated from 1920. Since then, not much is known about the family (even to the Order Ephemeroptera) to the State. The main goal of this study was to survey fauna of Leptophlebiidae in the Santa Catarina State based on nymphs. The material was obtained from the collection deposited at the Laboratorio de Pesquisa em Ecologia e Quimica of the Universidade Comunitaria da Regiao de Chapeco, besides additional specimens collected between 2008 and 2009. Occurrences were plotted in the hydrograph map of Santa Catarina State, with one map for each genus. The Leptophlebiidae nymphs were recorded in 26 aquatic environments that included small streams and rivers. We identified 24 morphotypes distributed in 12 genera. Number of genera in the Western of Santa Catarina increased from eight to 15. Thraulodes, Ulmeritoides and Homothraulus presented higher frequency of occurrence in the region. Leentvaaria and Hermanella were associated to regions well conserved such as in the Araucaria forest. Needhamella and Segesta were related mainly to Irani River.

The nymph of Hermanellopsis arsia Savage & Peters, 1983 (Ephemeroptera: Leptophlebiidae) from Brazilian Northeastern Region
Zootaxa, 2020Co-Authors: Stênio R. S. Nascimento, Lucas R. C. Lima, Erikcsen Augusto Raimundi, Carlos Augusto Silva De AzevêdoAbstract:Hermanellopsis Demoulin, 1955 is a genus of Leptophlebiidae known from adults of both sexes and is represented solely by two species, both from South America: Hermanellopsis arsia Savage & Peters, 1983, described only from male subimago; and H. incertans (Spieth, 1943) described from male imago and female subimago. Edmunds et al. (1976) provided the generic description for the supposed nymph of Hermanellopsis. However, Savage & Peters (1983) revised the genus, and study of related genera raised doubt about the identity of the proposed nymph. Thus, the nymph of Hermanellopsis has remained unknown until now.
