<strong>Review of <em>Waltzoyphius</em> McCafferty &amp; Lugo-Ortiz, 1995 and <em>Zelusia</em> Lugo-Ortiz &amp; McCafferty, 1998 (Ephemeroptera: Baetidae)</strong>

Abstract

The genera Waltzoyphius McCafferty &amp; Lugo-Ortiz and Zelusia Lugo-Ortiz &amp; McCafferty are revised in the present paper based on fresh and historical material, including types. New diagnostic features are presented in order to differentiate nymphs of the two species of Waltzoyphius. The adults of both species, and therefore, the adults of the genus are described for the first time. A new species of Zelusia is described, and based on the recognition of this new species, the distribution of Z. principalis Lugo-Ortiz &amp; McCafferty appears to be restricted to a small area near the type locality. Adults of Zelusia are also described for the first time, based on the new species.

The incredible diversity of Labiobaetis Novikova &amp; Kluge in New Guinea revealed by integrative taxonomy (Ephemeroptera, Baetidae)

“…Another very important character is the femoral patch, which is considered to be a synapomorphy of the Baetini (Waltz et al 1994), in Labiobaetis it is often rudimentary or absent, which seems to be a secondary loss. There are a few taxa outside Labiobaetis with a convergent excavation at the maxillary palp: one is Indobaetiscostai Müller-Liebenau & Morihara, 1982 (Müller-Liebenau and Morihara 1982: figs 1d, 2d, McCafferty and Waltz 1995, Kluge and Novikova 2014), other species of Indobaetis do not show this character; other two species belong to the Neotropical genus Zelusia Lugo-Ortiz & McCafferty, 1998 (Salles et al 2016). Two species from New Guinea ( L.orientis sp.…”

Direct analysis of vicariance in Neotropical mayflies (Ephemeroptera)

“…We hope that future research dating the sister clades could test Cienc (2019) 91(4) e20181130 7 | 13 these hypotheses, nevertheless some studies have estimated divergence in mayfly sister species ranging 3 to 9 Mya (Sekiné et al 2013, Bisconti et al 2016. Zelusia Lugo-Ortiz and McCafferty (1998), with two described species, presents a similar vicariant pattern (Salles et al 2016). Two conflicting hypotheses have been proposed to explain patterns of the Pantepui region: the idea of evolution in isolation obtained support from Oligoneuriidae, while the vertical displacement hypothesis (Desamore et al 2014) would explain the other mayfly vicariants at species level.…”
