ABSTRACT The taxonomic status and the geographic distribution of two species, Pelidnota gounellei (Ohaus, 1908) and P. ludovici Ohaus, 1905, is revised and the species are revalidated. A lectotype for Pelidnota tricolor Nonfried, 1894 is designated. The taxonomy of the species is briefly discussed, and a distribution map for the reviewed species is also provided. The distribution range of P. gounellei is expanded to the Minas Gerais state, Brazil.
RESUMO
ABSTRACT Scarabeoidea (Insecta: Coleoptera) present more than 2000 species recorded from all over Brazil. They have been scarcely recorded from caves, and truly troglobitic species are yet to be found in the country. In this study, we carried out a review of all existing scarab beetles deposited until 2017 in the Coleção de Invertebrados Subterrâneos de Lavras (ISLA), at the Universidade Federal de Lavras (UFLA) (Minas Gerais, Brazil), one of the most important collections of subterranean invertebrates in South America. Ninety-two individuals belonging to 52 species were recorded, distributed in six families (Cetoniidae, Hybosoridae, Melolonthidae, Passalidae, Scarabaeidae and Trogidae). Scarabaeidae was the most diverse of them, representing more than 50% of the total of species recorded. We found Scarabeoidea beetles in 51 of the ~ 1600 caves examined, distributed in nine Brazilian states: Alagoas, Bahia, Distrito Federal, Espírito Santo, Goiás, Minas Gerais, Pará, Piauí, and Tocantins. Our results provide evidence that Scarabaeoidea beetles are not frequent in Brazilian caves, and their records in this kind of environment are mostly accidental. Exceptions include Trogidae and Aphodiinae species, which may be associated with bat guano. Our study presents the first list of Scarabaeoidea species sampled in Brazilian caves.
RESUMO
A new species belonging to genus Eupatorus Burmeister, 1847, Eupatorus pyros Prandi Grossi, new species (Scarabaeidae: Dynastinae: Dynastini: Chalcosomina), from southwestern China is described and illustrated. The new species is close to E. birmanicus Arrow, 1908. A distribution map and an identification key for the Eupatorus siamensis species-group are provided.

Gibboryctes Endrödi, 1974 (Coleoptera: Scarabaeidae: Dynastinae: Oryctini) is an uncommon Neotropical genus comprising five valid species (Gasca-Álvarez Ratcliffe 2011; Dupuis 2019). Endrödi (1974) established the genus based on Gibboryctes szelenyii Endrödi, 1974 and defined it by the absence of sexual dimorphism; short, triangular, and pointed clypeus; bidentate mandibles projected beyond the anterior clypeal margin; and protibiae quadridentate. After that, Gibboryctes waldenfelsi (Endrödi, 1977) and Gibboryctes gracilicornis (Prell, 1912) were assigned to Gibboryctes, from Strategus Kirby, 1828 and Heterogomphus Burmeister, 1847, respectively (Ratcliffe Dechambre 1983; Dupuis Dechambre 2008). Gibboryctes bollei Dechambre, 2006 and Gibboryctes impunctatus Dupuis, 2019 were subsequently described.

The taxa of the genus Megasoma Kirby, 1825 (Coleoptera, Scarabaeidae, Dynastinae) related to M. gyas (Jablonsky in Herbst, 1785) are revised. Megasoma (M.) gyas is recognized as a monotypic species restricted to the Caatinga biome of northeastern Brazil. Megasoma gyas rumbucheri Fischer, 1968, is considered as a new synonym of M. gyas. The "long-horned M. gyas" is recognized as a separate polytypic species M. (M.) typhon (Olivier, 1789) with the nominative subspecies occurring through the Mata Atlântica biome of Brazil, from Bahia to São Paulo states and M. (M.) typhon prandii Milani, 2008 restricted to a small area in the state of Santa Catarina, South Brazil. Megasoma gyas porioni Nagai is considered as a new synonym of M. typhon typhon. The "short-horned M. gyas" occurring in Minas Gerais, São Paulo, and southwestern Bahia, is recognized as a separate new species and described as M. (M.) hyperionsp. nov. The paper includes an historical research and the redescriptions of the other nominal species of the genus. Distribution maps and a key to species in the M. (M.) gyas species group (males and females) are also provided.

The immature stages of Casignetus MacLeay, 1819 (Coleoptera: Lucanidae: Lucaninae: Casignetini) are revised with the description of third instars of males and female of C. humboldti (Gyllenhal, 1817), and C. spixi (Perty, 1830), and female of C. lindei (Boileau, 1899). Pupae of both sexes of C. humboldti, and female of C. lindei are also described for the first time. Casignetus larvae can be recognized by the form of the pars stridens, formed by a slightly arched, longitudinal row of robust, and sclerotized teeth, and by the fusion of the femur and trochanter in prothoracic and mesothoracic legs. Additionally, new characters are proposed for Casignetus species: frontal sutures curvature; epicranial setae; epipharynx and hypopharynx setae; and number and shape of stridulatory teeth.

Moronius Grossi Vaz-de-Mello, 2015 (Coleoptera: Scarabaeidae: Rutelinae: Rutelini) is the latest genus described within the subtribe Areodina (Grossi Vaz-de-Mello 2015). Areodina consists of 11 genera distributed throughout the New World (10 genera) and Africa (one genus) (Jameson 1990; Grossi Vaz-de-Mello 2015). Moronius is distinguished from other genera of Areodina by: 1) the pentagonal clypeal shape with the apex strongly reflexed, and 2) the hind wings with the anterior margin near RA1+2, RA1+3, and apical hinge setose. The South American genera of Areodina form a distinct clade (Jameson 1990) composed of Oplognathus MacLeay, 1819, Areoda MacLeay, 1819, and Byrsopolis Burmeister, 1844. Oplognathus and Areoda are differentiated by the presence of a forward-projecting mesoventral process, which is absent in both Byrsopolis and Moronius. These two latter genera are similar according to the characters presented in the Jameson (1990) phylogeny and are differentiated by habitus colour, shape of clypeus, and antennal club length (Grossi Vaz-de-Mello 2015).

RESUMO
Two new species of Cyclocephala constituting a new species group in the genus, Cyclocephala machadoi sp. nov. (Holotype male deposited in CERPE: Brazil, Minas Gerais State, São Gonçalo do Rio Preto municipality, Parque Estadual do Rio Preto) and C. everardoi sp. nov. (Holotype male deposited in CERPE: Brazil, Minas Gerais State, 8 km north of Cristália municipality), are here described and illustrated. The only two males known were collected with light traps and have antennal lamellae much larger than other South American species, along with large eyes and a quadrate narrow clypeal apex.

New distributional data are reported on the rare phanaeine dung beetle, Oxysternon pteroderum Nevinson, 1892, based on five specimens recently collected between 1985 and 2010. Before the present study, Oxysternun pteroderum had been reported solely from the super-moist Atlantic coastal forests of southeastern Brazil. We now believe that the distribution of Oxysternun pteroderum follows the riparian areas of large rivers connected to the super-moist forest ecosystem.
