The present study records for the first time the small cichlidae fish Laetacara dorsigera (Heckel, 1840) at Uruguay River basin and state of Rio Grande do Sul, southern Brazil, previously known from Amazon, Paraná and Paraguay River basins. Although the ichthyofauna of Uruguay River basin is relatively well known, this record suggests that there are still unexplored environments, such as wetlands, where there may be species not yet reported, and found in other hydrographic systems.

The African spider Cithaeron reimoseri Platnick, 1991 is registered for the first time in the New World, based in two females collected at Porto Alegre, Rio Grande do Sul, Brazil. Until now C. reimoseri was known only by the holotype from Eritrea. The species C. praedonius O. P.-Cambridge, 1872 was, until now, the only known species of the family with worldwide distribution and is considered prone to introduction in anthropic environments. Cithaeronidae are considered lower gnaphosoids being identifiable by the depressed posterior median eyes and the pseudosegmented tarsi.

The new species herein described, collected in the Jacuí and Uruguay River basins, Rio Grande do Sul, Brazil, can be distinguished from the already known species of the genus, but Oligosarcus jenynsii, O. perdido, O. acutirostris, O. solitarius and O. hepsetus, by the number of perforated lateral line scales. It shares with the first two species the absence of a premaxillary foramen, present in the last three species and differs from O. jenynsii by having a smaller orbital diameter and the tip of the pectoral fin failing to reach the pelvic-fin origin, and from O. perdido by the presence of more horizontal scale rows around the caudal peduncle.

Jupiaba Zanata, 1997 is a genus with small species within Characidae, identified by a pair of modified bones in the form of spines just anteriorly to pelvic-fin base. The genus is mostly distributed throughout the Amazon drainage, except J. acanthogaster (Eigenmann, 1911), which also occurs in the Paraguay river basin. In this work, we recorded for the first time J. acanthogaster in the Sucuriú River drainage, upper Paraná river basin, Brazil. Its occurrence may be a consequence of the historical hydrological interaction between the Paraná and Paraguay river basins.

Mecistogaster is a New World genus of Pseudostigmatidae (Odonata) that is poorly studied due to its preference for flying in forest clearings and trails. In Brazil, only one endemic species, Mecistogaster amalia (Burmeister), is known. The distribution of M. amalia extends from Southest Brazil (Rio de Janeiro and São Paulo states) to Argentina. Herein, we report M. amalia for the first time in Rio Grande do Sul State, Southern Brazil. This record extends the species’ range ca. 630 km from the previous report at Paranaense Forest in Misiones province. Mecistogaster amalia (Burmeister) Odonata: Pseudostigmatidae: Primeiro Registro para o Estado do Rio Grande do Sul, Brasil Resumo. Mecistogaster é um gênero da Família Pseudostigmatidae, restrito ao Novo Mundo e pobremente estudado devido sua preferência por clareiras e trilhas dentro de matas. No Brasil, apenas uma espécie é conhecida, Mecistogaster amalia (Burmeister). A distribuição de M. amalia se estende do sudeste do Brasil (nos estados do Rio de Janeiro e São Paulo) até a Argentina. Aqui, reportamos pela primeira vez M. amalia para o estado do Rio Grande do Sul State, Sul do Brasil. O presente estudo amplia o registro de ocorrência da espécie em 630 km, a partir do registro anterior na Floresta Paranaense, na Província de Missiones, Argentina.

The genus Anax comprises a group with cosmopolitan distribution and 27 species around the world. In Brazil, Anax is represented by three species: A. amazili, A. concolor and A. longipes. Anax amazili occurs, in South America, from French Guiana to Argentina, and in Brazil is distributed in the northeast and southeast of the country. We have reported A. amazili for the first time in southern Brazil, from the state of Rio Grande do Sul, extending its current distribution about 1000 km.

ABSTRACT: Eimeria infections are common in the sheep industry worldwide. Lambs are more susceptible to coccidiosis, especially in stressful conditions, being infected by different species of the parasite. Eimeria crandallis and Eimeria ovinoidalis are considered the most pathogenic, causing reduced growth, dehydration, anorexia, and death. In this study, the frequency of Eimeria species was evaluated in lambs from the southern region of the Rio Grande do Sul state, Brazil. Fecal samples from 248 lambs, from 19 farms, were tested for the presence of oocysts. The positive samples were re-examined and the sporulated oocysts analyzed morphometrically to identify the presence of Eimeria species. In 100% of the evaluated farms, there were animals positive for the protozoan. The frequency of Eimeria species was: E. ovinoidalis (94.74%), E. crandallis (89.47%), E. granulosa (78.95%), E. parva (68.42%), E. ahsata (63.13%), E. punctata (42.11%), E. bakuensis (36.84%), E. faurei (10.53%), and E. pallida (5.26%). Mixed infection was found in 94.74% of the samples. This research describes, for the first time, the occurrence of E. crandallis and E. ovinoidalis infecting lambs in the study area. The wide distribution of this protozoan and the high frequency of pathogenic species show the importance and potential damage of sheep coccidiosis in herds from Rio Grande do Sul.

Rio Grande do Sul (RS) is the southernmost state in Brazil and includes areas within the Pampa and Atlantic Forest biomes. The semiaquatic bugs (Hemiptera, Heteroptera, Gerromorpha) from RS are poorly known, with only 14 previously recorded species. We carried out two expeditions in this state, in 2002 and 2019, across 19 municipalities. Here, we provide new records for 19 species, of which 13 are recorded for the first time from the state, five have their distributions expanded, and one is recorded again from a same locality previously reported in the literature. Furthermore, 13 species were collected for the first time in the Pampa biome and one in the Atlantic Forest.

The Great Dusky Swift Cypseloides senex occurs mainly in Argentina, Bolivia and Brazil. Little is known about the status of this species in the state of Rio Grande do Sul, Brazil. To fill this gap, several ornithologists and museum collections were consulted for records. This paper presents records for nine new localities in the state of Rio Grande do Sul. Cypseloides senex occurs along the central and northeast portions of the Planalto escarpment and the upper valley of the Uruguay River.
