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 O. pteroderum follows the riparian areas of large rivers connected to the super-moist forest ecosystem.

The new species are compared with related species and illustrated. Dorsal habitus, head, pronotum, elytra and male genitalia of all species are figured and a distribution map is included. Incadorcus cuzcoensis Arnaud, Noguchi & Bomans is elevated to species status and Incadorcus kirchneri Schenk is synonymized with Incadorcus michellae Arnaud & Bomans. The species Metadorcus rufolineatus Nagel and Aegognathus nigrosuturalis Weinreich are transferred to the genus Onorelucanus.

The diagnostic characters of the genus are confirmed, distinguishing it from other Brazilian Areodina mainly by: quadrangular clypeus with trilobate apex in males, rounded in females, extending beyond labrum in both sexes; mandibles with three distinct teeth; maxillae with six teeth; antenna with 10 antennomeres; 10 elytral striae; mesoventral process present; and asymmetrical parameres. The genus and all three species are redescribed, and the female of Oplognathus bahianus Ohaus, 1912 is described for the first time. We consider Oplognathus helmenreichi var. maculicollis Ohaus, 1914 an unavailable infrasubspecific taxon that is conspecific with Oplognathus helmenreichi Ohaus, 1905; its distribution is updated, and the different spelling of the specific epithet is discussed.

Moreover, the adoption of integrated systems has increased in Brazilian farms in the past few years, reaching significant numbers such as 11.5 million hectares covered by some sort of integration, including silvopastoral systems (SPS). This study aimed to evaluate the diversity of Coleoptera species and dung pats decomposition in an open pasture (OP) of Urochloa brizantha cv. Marandu and in an SPS with Eucalyptus urograndis clone H13. There were no significant differences in dung beetle richness or abundance in OP and SPS, as well as similar rates of dung pats disintegration. Most insects were captured during the rainy season, and richness and diversity of species were similar between systems. The traps' distance to the Eucalyptus rows did not influence the number of dung beetles sampled; however, fewer individuals were captured under the tree rows. We suggest the importance of beetles for cattle dung decomposition and biological control of parasites, eventhough community structure was similar between systems with different habitat complexity.

This work aimed to revise the identity of this species based on the study of primary types, identified material collected in previous works and descriptions on literature. The confirmed name for this white grub from Southern Brazilian crops was fixed to C. signaticollis Burmeister, an important pest of several no-tilling crops in Argentina, Uruguay and also in Australia, where it was introduced and is widely established. Taxonomical remarks on adults and larvae are included, in conjunction with depicted images of diagnostic characters. The geographical distribution of C. flavipennis from Southern South America is disregarded. New strategies of pest management for C. signaticollis should be assessed in Southern Brazil taking into account all the background of knowledge on this species from the neighboring countries.

The archipelago has suffered major ecological disturbances due to several human interventions. In 1737, fortifications were built, and the archipelago was transformed into a penal colony for almost 200 years. During this period, a large part of the native vegetation was devastated while exotic plants and animals were introduced to serve as food (Teixeira et al., 2003; Serafini et al., 2010). The human population in the archipelago increased significantly in 1942 through military occupation (i.e., World War II). Afterwards, significant changes were observed in the archipelago due to: • Several insecticide applications campaigns (i.e., DDT) for mosquito-control; • Wild animal introductions, such as the Teju lizard (Salvator merianae Duméril & Bibron) and the Mocó cavy (Kerodon rupestris Wied-Neuwied); • Release of birds seized in trade fairs and public markets of Recife (i.e., Saffron finch (Sicalis flaveola (Linnaeus)), House Sparrow (Passer domesticus (Linnaeus)), and the White-bellied seedeater (Sporophila leucoptera (Vieillot));

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.

A synopsis of the genus was provided by Endrödi (1969, 1985) and since his last contribution no new species have been described. In this paper we describe a new third species from Entre Ríos, Argentina. At present, all Eremobothynus species are endemic to Argentina and known from only few localities. Taxonomic notes are given for E. cornutus (Steinheil), leading to the discussion and correction of some diagnostic characters of the genus. Additionally, a key for the identification of the species is provided.

New diagnostic characters are illustrated and discussed for the genus. An illustrated identification key for all Podischnus species, and an up-to-date distribution map for the Brazilian species of Podischnus are provided. Moreover, we propose the inclusion of P. limeirai sp. nov. in the Red List of Threatened Species (IUCN) due to the fast loss of the Oriental Amazon Forest remnant fragment in that region.

The new species is distinguished from all other Chlorota species by having the striped elytral pattern with red costae, and surface of pronotum dull, dark, metallic, and smooth. An updated map and a key for species and subspecies that occur in Brazil are also presented.

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...
