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.

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.

This note extends the distribution of the dwarf cichlid fish Apistogramma borellii, and is the first record of the species, and the genus for the state of Rio Grande do Sul, southern Brazil, suggesting that the fish diversity of wetlands, although relatively high, is still poorly investigated in southern Brazil.

This research describes the infestation by ticks and lice in free-living coatis (Nasua nasua Linnaeus, 1766) with sylvatic and synanthropic habits living at the Iguaçu National Park (INP), state of Parana, southern Brazil. During the months of September 2014 and from March to April 2015, ticks and lice were collected from 86 free-living coatis from INP. Among the animals analyzed, 99% (85/86) were infested with ectoparasites, Amblyomma spp. larvae (n=23), nymphs of Amblyomma brasiliense (n=77), Amblyomma coelebs (n=427) and Haemaphysalis juxtakochi (n=6) being observed, as well as Amblyomma ovale adults (n=46). Lice were found in lower prevalence (13%, 11/86), nymphs (n=31) and adults (n=9) of Neotrichodectes pallidus. Summary results show feral coatis with sylvatic and synanthropic habits as competent hosts for ixodid ticks and lice, arthropods responsible for the transmission of pathogens for carnivores, others wildlife and humans. This paper presents the first record of H. juxtakochi infesting coatis in Brazil.

The present report is part of a larger study on the helminth fauna of Neotropical Cormorants, Phalacrocorax brasilianus (Gmelin, 1789) in Brazil, particularly, in the southernmost State of Rio Grande do Sul. The nematodes which were found loose in the proventriculus/ventriculus or in groups of adults of different ages and of L3 and L4 larval stages, forming eosinophylic granulomas had a prevalence of 100% in 47 Neotropical cormorants from Lago Guaíba, Municipality of Guaíba. The morphology of the labia/interlabia, the distribution pattern of the caudal papillae in males examined under scanning electron microscopy (SEM), and the tips of the spicules allowed determination of the species as Contracaecum rudolphii Hartwich, 1964 sensu lato (s. l.). This is the first record of C. rudolphii in southern Brazil.

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.

Twenty-one free-living species of turbellaria (Platyhelminthes) were found in the Pacaya-Samiria National Reserve (Loreto, Peru), a Peruvian Amazon floodplain. The total 21 observed taxa comprise five species of Catenulida, two species of Macrostomida, two species of "Lecithoepitheliata", 10 species of Rhabdocoela and two species of Tricladida. Most of the species are cosmopolitan and occur in freshwater habitats worldwide. Of the species collected, only Mesostoma ehrenbergi was previously known from this region, whereas five species of Rhabdocoela were only recently described from the Pacaya-Samiria Reserve. Some morphological, distributional and ecological remarks are provided.

A new species of the genus Nitzschia was found in epiphyton and microphytobenthos at the Patos Lagoon salt marsh (Rio Grande do Sul State, southern Brazil). Nitzschia papillosa sp. nov. was described under light and scanning electron microscopy and compared with other species from the section Lanceolatae. The species presents features shared by several species of the genus such as a linear-lanceolate outline, cuneate ends and irregularly distributed fibulae. The distinguishable feature is a row of dots on the margin opposite to the fibulae. In scanning electron microscopy, these structures appear as silica excrescences, little rounded or squared, which we refer as papillae, situated at the transapical costae in the internal valve face. This is the first record of this kind of ornamentation in Nitzschia species.

Phyllobaeis is mainly a Neotropical genus and contains six species. It has a squamulose primary thallus (except for one species with crustose primary thallus), stipitate podetia, and simple or 1-septate hyaline, ovoid to fusiform ascospores. The species occur mainly on soil in altitudes of 700 to 4,400 m. In Brazil three species are known, recorded mainly from the southeast. The aim of this work is contributing to the knowledge of the distribution of Phyllobaeis in Brazil. We studied specimens from southern Brazil. The morphological, anatomical and chemical analyses follow standard lichenological protocols. We found two species in southern Brazil: Phyllobaeis erythrella, which is the first record to Paraná and Rio Grande do Sul states; and P. rubescens, which is the first record to Paraná and Santa Catarina states. Both occur in environments on the plateau, as well as in high-grasslands, between 700 to 1400 m altitude. A distribution map in Brazil, descriptions, figures and a key to the species of Phyllobaeis are given.
