The Neotropical genus Ruppeliana Young, 1977 comprises 13 species. The following three are redescribed and illustrated herein: R. coronata (Signoret, 1853), R. fulva (Taschenberg, 1884), and R. nigripes (Signoret, 1853). Additionally, three new species are described and illustrated: R. delicata sp. nov., R. robusta sp. nov., and R. tridentata sp. nov., from the states of Paraná, Santa Catarina, and Rio de Janeiro, respectively. A revised diagnosis, a key to males, a distribution map, and a neotype designation for R. grossii Cavichioli et al., 2017 are also proposed. Keywords.

European Journal of Taxonomy 1022: 51–84. https://doi.org/10.5852/ejt.2025.1022.3081 Introduction Ruppeliana was established by Young (1977) to accommodate Tettigonia signiceps Stål, 1862, along with the following species: Tettigonia coronata Signoret, 1853; T. coronulifera Stål, 1862; T. episcopalis Signoret, 1853; T. fulva Taschenberg, 1884; T. glaucomaculata Germar, 1821; T. nigripes Signoret, 1853; and T. taschenbergi Berg, 1899. Additionally, Young described a new species, R. tatia. Recent studies have described six new species: R. caelimaculata and R. flavivirescens (Carvalho et al. 2014), as well as R. barbarensis, R. grossii, R. longiphallus, and R. serrana (Cavichioli et al. 2017). Furthermore, R. coronulifera and R. taschenbergi were synonymized with R. signiceps (Stål, 1862) (Carvalho et al. 2014). At the present moment, Ruppeliana comprises 13 species. Although the original genus description included records from southern Brazil and northern Argentina, the Argentinian record could not be confirmedinsubsequentstudies(Cavichioliet al. 2017). Ruppeliana was placed near Pawiloma Young, 1977 due to similarities in both male and female genitalia (Young 1977). However, they differ in the former having elongated basal processes of the aedeagus (Carvalho et al. 2014). Representatives of Ruppeliana are colorful and robust, measuring approximately European Journal of Taxonomy 1022: 51–84 (2025) 52 10 millimeters, but they are not commonly found in collections (Cavichioli et al. 2017). This rarity likely explains why Young (1977) did not propose a dichotomous key for the genus. The original descriptions of R. coronata, R. episcopalis, R. fulva, R. glaucomaculata, R. nigripes, and R. signiceps are brief and primarily focused on external morphology. Most of these species were later redescribed and illustrated by Young (1977), except for R. nigripes and R. coronata, for which the author suggested a possible synonymy. The illustrations of R. coronata were based on a non-type series male, while for R. nigripes, Young (1977) provided only a lateral view of the pygofer and a ventral view of the aedeagus. Due to the absence of detailed morphological descriptions and illustrations in previous studies, we redescribed and illustrated the species R. coronata, R. nigripes, and R. fulva, describing the color variation for the latter. Additionally, we describe three new species: R. delicata sp. nov., R. tridentata sp. nov., and R. robusta sp. nov. We also provide a key to the males of the genus, an occurrence map and a neotype designation for R. grossii. Material and methods The terminology adopted here follows Young (1977) for the main terms, Hamilton (1981) and Mejdalani (1993, 1998) for facial areas of the head, and Nielson (1965) for female genitalia. The terms “gonoplac” and“sculptedareasoffirstovipositorvalvule”followMejdalani(1998).Thetechniquesforgenitalia preparationfollowCavichioli&Takiya(2012),withmodificationsasinDomahovski(2024).The dissected parts were stored in microvials with glycerin, as suggested by Young & Beirne (1958). Digital images of habitus were obtained with a Leica MZ12.5 stereo microscope with a SCMOS 05000KPB digital camera attached and were stacked using CombineZP software. First and second valvulae and gonoplacs were separated and mounted on a temporary slide covered with a cover slip, then photographed using the former mentioned digital camera, attached to a Nikon optical microscope at40×and100×magnification. The specimens examined are deposited in the Coleção Entomológica Padre Jesus Santiago Moure, Departamento de Zoologia, Universidade Federal do Paraná, Curitiba, Brazil (DZUP), and in Museu Nacional do Rio de Janeiro (MNRJ). The occurrence map was generated using Simple Mappr (available online at https://www.simplemappr.net/), with data obtained from the literature (Young 1977; McKamey 2007; Froza et al. 2024; and original descriptions), from the online source Taxonomic Catalogue of Brazilian Fauna (Takiya et al. 2024), and from specimen labels deposited at DZUP.

Remarks Ruppeliana coronata and R. nigripes were suggested by Young (1977) to be possible synonyms. However, they can be distinguished by several morphological characteristics. The forewing coloration is reddish at R. coronata and brown in R. nigripes. In dorsal view, the pygofer apices are directed inwards in R. coronata (Fig. 15A), whereas they are subparallel in R. nigripes (Fig. 15B). Additionally, the subgenital plate reaches or surpasses pygofer apex in R. coronata, while in R. nigripes, it does not extend beyond pygofer apical portion.
