Ceratium Schrank is a planktonic dinoflagellate ubiquitous in temperate and subtropical freshwater environments from Northern Hemisphere. Over the past two decades, Ceratium species have been recorded in South American water bodies, with expansive behavior and fast colonization. This study registered C. furcoides (Levander) Langhans and C. hirundinella (O. F. Müller) Dujardin for the first time in South Brazil. Ceratium furcoides was found in samples from States of Paraná and Rio Grande do Sul and C. hirundinella occurred only in the southernmost Brazil. No co-occurrence of these species was detected on samples. The morphological variation, as well as the dispersal patterns of these species in Brazilian environments, is discussed based on LM and SEM analyses.

Shape And Size

Within Dalyelliidae Graff, 1905, Gieysztoria Ruebush & Hayes, 1939 is the most widely distributed and speciose genus, members of which live in marine, brackish, or freshwater habitats (Van Steenkiste et al., 2012). Gieysztoria is composed by ~97 free-living species (Tyler et al. 2016), and species identification is mainly made on the male copulatory system, which has an armed penis (stylet) with different configurations of spines (Noreña et al., 2016). The stylet configuration of Gieysztoria species is traditionally split into two groups: Aequales (spines of similar shape and size) and Inaequales (spines of different shape and size) (Luther, 1955). In the neotropics, specimens of Gieysztoria belong to both the Aequales and Inaequales group   and are well represented (Damborenea et al., 2005; Noreña et al., 2003). According to Braccini et al. (2016, 2017), there are 16 species of Gieysztoria in Brazil, mainly distributed in the southern region. South Brazil harbours a mosaic of wetlands that are considered hot spots of biodiversity, including the Taim Ecological Station (ESEC Taim) protected area that was designated as a Ramsar site (Ramsar, 2017). In the present study, Gieysztoria falx Brusa, Damborenea & Noreña, 2003 is registered in the ESEC Taim, located in Rio Grande do Sul. It represents the first record of G. falx in Brazil. Illustrations and comments on stylet configuration are given.

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.

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 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 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.

The tribe Diglottini Eichelbaum, 1909 comprises two halophilous rove beetle genera Diglotta Champion, 1899, and Paradiglotta Ashe & Ahn, 2004. The tribe contains eight known species distributed in the Nearctic and West-Palaearctic regions, and also Fiji Islands and New Zealand. This tribe is recorded for the first time from South America with the description of a new species, Diglotta brasiliensis n. sp. from southern Brazil (Paraná). Characters of the mouthparts, aedeagus and spermatheca of the new species are illustrated and compared with other Diglotta species. Sexual dimorphism is reported for the first time in the genus.

Heteropanope glabraStimpson, 1858 belonging to family Pilumnidae is reported for the first time from the mangrove mudflats of India. The identification of the species is difficult because the species shares similar morphological characters with other closely related species likeBenthopanope indica(De Man, 1887). Studies in the past have reported the presence ofH. glabrafrom coastal areas of Burma to Japan. The present study reports the presence ofH. glabraon the western coast of India, which lies outside the old distribution range of the species.

Micrurus silviae is a coralsnake with a triadal pattern, and is one of the eight species found in southern South America. In Paraguay there are six taxa recorded: M. altirostris, M. baliocoryphus, M. frontalis, M. pyrrhocryptus, M. corallinus, and M. lemniscatus carvalhoi. Here we present a record of M. silviae, an additional and seventh species for the country. Previously M. silviae was known only from Rio Grande do Sul state, in southern Brazil. The specimen was found in South American Mesopotamian Grasslands ecoregion, with natural grassland in the Department of Itapúa.
