First record and new species of Tortopsis Molineri, 2010 (Ephemeroptera, Polymitarcyidae) from Brazil

Abstract

A new species of the recently erected genus Tortopsis is described from males and females imagos collected in Macaé river, Rio de Janeiro State. Tortopsis canum sp. nov. can be recognized by the color pattern of the head and pronotum, strongly shaded with black in both sexes, male genitalia with parastyli long and straight and female parastyli receptor “C” shaped, with receptors large, occupying nearly all extension of sternum VIII. This new species represents the first record of the genus Tortopsis in Brazil.

Tortopus Needham & Murphy and Tortopsis Molineri (Ephemeroptera, Polymitarcyidae) new species and new records from Brazil and Ecuador

“…Previously only two records of Tortopus harrisi from Mato Grosso (reported in the original description by Traver 1950) and Mato Grosso do Sul , and one of Tortopsis canum in Rio de Janeiro (Gonçalves et al 2011) were known from Brazil. With the new information given here, two additional species for each genus are reported for this country: Tortopus igaranus, Tortopus ipixuna, Tortopsis limoncocha and Tortopsis spatula.…”

“…The subfamily Campsurinae (Ephemeroptera: Polymitarcyidae) is represented by three genera distributed in the Neartic and Neotropical regions: Campsurus Eaton 1868, Tortopus Needham & Murphy 1924 and Tortopsis Molineri 2010, reaching 61 known species (Dominguez et al 2006;Molineri 2010;Emmerich & Molineri 2011;Gonçalves et al 2011). Tortopus and Tortopsis are considered sister genera in the phylogenetic analysis proposed by Molineri (2010).…”

“…The genus Tortopus, with six described species (Molineri 2010), is known in Brazil only by T. harrisi Traver, 1950, from Mato Grosso and Mato Grosso do Sul states (Traver 1950;Molineri et al 2010), and the male imago is only known from the holotype (Traver 1950). The genus Tortopsis, with 10 described species, was recently recorded from Brazil, from Rio de Janeiro state, with the description of the imagos of T. canum Gonçalves, Da-Silva & Nessimian, 2011(Gonçalves et al 2011.…”

New insights into the phylogeny of Tortopus Needham and Murphy and Tortopsis Molineri (Ephemeroptera, Polymitarcyidae) with description of three new species

“…Tortopsis is characterized by male genitalia with cylindrical penis, each penean arm separated from the base; ninth abdominal sternum entire, long curved parastyli present; female fore wing without additional veins between R 2 and IR, female sternum VIII with parastyli receptors C or V-shaped, and nymphs with a single subapical tubercle on mandibular tusks (Molineri 2010). Ten species are known from central Argentina to the northern United States of America (Molineri 2010;Gonçalves et al 2011;Molineri et al 2012): T. bruchianus (Navás), T. canum Gonçalves, Da Silva and Nessimian, T. limoncocha Molineri, T. obscuripennis (Domínguez), T. parishi (Banks), T. primus (McDunnough), T. puella (Pictet), T. sarae (Domínguez), T. spatula Molineri and T. unguiculatus (Ulmer). In Colombia, the genus is represented by only two species (T. unguiculatus and T. spatula) from several localities in the Amazonas department (Molineri 2010;Molineri et al 2012).…”

“…In Colombia, the genus is represented by only two species (T. unguiculatus and T. spatula) from several localities in the Amazonas department (Molineri 2010;Molineri et al 2012). Molineri (2010) performed a phylogenetic revision of all the species in Tortopus and Tortopsis, but the taxonomic knowledge has been growing, especially during the last decade, with the description of new species and stages (Gonçalves et al 2011;Molineri et al 2012).The aim of the present work is to describe two new species of Tortopsis and a new species of Tortopus recently collected in a biologically poorly known area in Colombia. Additionally, we amend the phylogeny proposed in Molineri (2010), including all the species presently known.…”
