Two new species of Cloeodes Traver (Ephemeroptera: Baetidae) from Espírito Santo, Southeastern Brazil

Abstract

In the present work, two new species of Cloeodes Traver are described based on nymphs and adults collected in the State of Espírito Santo, Southeastern Brazil. The main characteristics that distinguish the new species from its congeners are, in C. itajara sp. nov.: a) labrum with dorsal arc of setae composed of 12 setae, b) segment III of labial palp with robust and pectinate setae on inner margin, c) fore femur with apex projected, with 5−6 blunt setae, d) male imago with abdominal terga V−VII with a anterolateral triangular black mark; in C. aymore sp. nov.: a) labrum with dorsal arc of setae composed of 1 + 0 + 3 setae, b) fore femur with apex projected, with 2 blunt setae, c) male imago with abdominal terga IV with kidney-like median brown mark.

Phylogenetic analyses of CloeodesTraver and related genera (Ephemeroptera: Baetidae)

“…One of the species of Cloeodes described by Lugo‐Ortiz & McCafferty () from Australia was revalidated and transferred to Bungona Harker (Webb & Suter, ). Finally, the number of species of Cloeodes doubled in the Neotropics during this period, with more than ten species described from Argentina, Brazil and Uruguay (Salles & Lugo‐Ortiz, ; Salles et al ., ; Nieto & Richard, ; Massariol & Salles, ; Nieto & Emmerich, ; Massariol et al ., ).…”

New species and records of Cloeodes Traver, 1938 (Ephemeroptera, Baetidae) from Costa Rica

“…Individuals were found at 2054 m asl in cold waters of two cloud forest streams (Fig. 7); other non-Andean species have been reported between 159-1800 m asl (Nieto and Richard 2008;Gutiérrez and Reinoso-Flórez 2010;Massariol and Salles 2011;Massariol et al 2013;De Paul et al 2013;Gutiérrez and Dias 2015). Also, the new species was collected in a pristine forest region, which may be similar to other Cloeodes species in Brazil that seem to prefer remnant forest areas (Salles et al 2015).…”

First description of imago and redescription of nymph for Cloeodes irvingi Waltz & McCafferty, 1987 (Ephemeroptera: Baetidae)

“…There are 15 South American species of Cloeodes with adult stages described, however only three species, Cloeodes aymore Massariol & Salles, 2011, Cloeodes hydation McCafferty & Lugo-Ortiz, 1995, Cloeodes itajara Massariol & Salles, 2011, and Cloeodes jaragua Salles & Lugo-Ortiz, 2003 share similar characteristics with the imago of C. irvingi: segment II of forceps with constriction (Fig. 4); and hind wing with costal process hooked, located on basal third and with two longitudinal veins (Fig.…”

“…Cloeodes Traver (1938) has a widespread pantropical distribution with representatives in Africa (Waltz & McCafferty 1994;Jacobus et al 2006), Madagascar (Lugo-Ortiz et al 1999), Southeast Asia (Soldán & Yang 2003) and the Americas (e.g., Traver 1938;McCafferty & Lugo-Ortiz 1996;Wiersema & Baumgardner 2000;McCafferty et al 2004;Nieto & Richard 2008;McCafferty et al 2012). In South America, there are 23 species known: eight from nymphs, five from adults, and ten from both nymphs and adults (Nieto & Richard 2008;Gonçalves et al 2010;Massariol & Salles 2011;Nieto & Emmerich 2011;Massariol et al 2013). In Brazil, 11 species are reported .…”
