Gastrointestinal Helminth

Helminthological studies with Chelidae freshwater turtles in South America were conducted in Argentina, Uruguay and Brazil, where nematodes, digeneans and monogeneans were reported. In this context, the study aims to report new cases of gastrointestinal helminth parasites of Acanthochelys spixii, Hydromedusa tectifera, and Phrynops hilarii. A total of 65 hosts from the southern region of Rio Grande do Sul, Brazil, were examined. Seven taxa belonging to Nematoda, Digenea, and Monogenoidea have new cases on hosts Chelidae in South America, as well as a Nematoda and two Digenea have new host cases for Brazil. Thus, the study expands the knowledge about the diversity of helminths and the geographic distribution of taxa associated with Chelidae turtles.

The two endemic, endangered species, Bacch­aris hypericifolia (Asteraceae) and Hypericum salvadorense (Hypericaceae), were known only for the Rio Grande do Sul state, in Brazil. In this paper we report two new occurrences of these species in Santa Catarina, expanding their geographic distribution to the north. Baccharis hypericyfolia and H. salvadorense were collected in areas of PPBio (Programa de Pesquisa em Biodiversidade) project. These novelties evidence the presence of knowledge gaps regarding the flora and little collecting effort in the grasslands from Southern Brazil.

Distribution records of poorly-known species are currently the most explored theme in the Brazilian seabird literature. If properly evaluated, this kind of information can improve our knowledge on distribution, migration and status of occurrence of these species. In this note we present new records for six species of poorly-known seabirds in the Brazilian coast, reviewing distribution records and defining their status of occurrence in the country. We consider Chionis albus (Gmelin, 1789) a pseudo-vagrant in Brazil and define its status as a scarce seasonal visitor from southern South America. We present the first records of Leucophaeus atricilla (Linnaeus, 1758) for Trindade Island, and of Leucophaeus pipixcan (Wagler, 1831) for the state of Rio Grande do Sul, and determined that the former is a vagrant in eastern Brazil and the latter a vagrant across the country. Anous stolidus (Linnaeus, 1758) is a vagrant in southernmost Brazil. We were unable to determine if records of Chlidonias niger (Linnaeus, 1758) for Brazil and southern South America refer to vagrancy or pseudo-vagrancy. Additionally, we verified the occurrence of breeding individuals of Anous minutus Boie, 1844 on Martin Vaz Island and confirmed that there is no evidence of breeding on neighboring Trindade Island.

This work presents new records and extends the geographic distribution of Heliconius sara apseudes in the Atlantic Forest of the state of Rio Grande do Sul. Five new records were taken along butterfly inventories carried out between 2005 and 2010 in distinct phytophysiognomies at Rio Grande do Sul northeast region: Swamp Forest, Atlantic Forest stricto sensu and Araucaria Moist Forest. The fact that all registers occurred in well preserved habitats of the Atlantic Forest emphasizes the need of conservation of this biome in Rio Grande do Sul.

Abstract Dioctophymatosis is caused by the giant kidney worm Dioctophyme renale which occurs in dogs, cats, and wild mammals. In Brazil, the disease has been diagnosed in dogs from several states around the country. In the present study, the occurrence of D. renale larvae in snakes from southern of Brazil is reported. Three specimens of Philodryas patagoniensis (Serpentes: Dipsadidae) (common names in Brazil: “parelheira”, “papa-pinto”) roadkill in the county of Capão do Leão, State of Rio Grande do Sul, southern Brazil, were necropsied. Two third-stage larvae of D. renale were found in the coelomic cavity of P. patagoniensis. This study reveals a new host for D. renale larvae in the southern region of the State of Rio Grande do Sul, Brazil. This particular geographic area of the country has stood out as several cases of D. renale infection have been reported in a number of vertebrates from this region including domestic dogs and cats and wild animals such as carnivores, fish, and freshwater turtles.

Collection Sites

One hundred eight rosy-billed pochards, Netta peposaca (Vieillot, 1816), collected in Brazil and Argentina were examined for endoparasites. Collection sites included the municipalities of Santa Vitória do Palmar and Jaguarão, Rio Grande do Sul State, Brazil (wintering site) and Alvear, Corrientes Province, northern Argentina (nesting site). Birds were frozen in dry ice after collection. During necropsy they were categorized according to sex and maturation, either adult or juvenile. The cestode Diploposthe laevis (Bloch) Jacobi, 1896 was found (prevalence 68.5%, mean infection was 2). The mean prevalence of D. laevis in Alvear (25.9%) was higher than found in Jaguarão and Santa Vitória do Palmar, Rio Grande do Sul (19%), and could be related to the nesting site and to the period when the birds may ingest a higher amount of food. This is the first record of a species of the genus Diploposthe in anatideans from South America, and the first record of the species in N. peposaca. Details of the cirrus pouch and vagina were described based on histological sections.

The Family

A taxonomic study of the fern genera Austroblechnum, Cranfillia, Neoblechnum, Lomaridium, and Telmatoblechnum, formerly Blechnum s.l. (Blechnaceae, Polypodiopsida), was conducted in southern and southeastern Brazil (Minas Gerais, Espírito Santo, Rio de Janeiro, São Paulo, Paraná, Santa Catarina, and Rio Grande do Sul) and 11 species were recognized (six of Austroblechnum, two of Cranfillia, one of Neoblechnum, one of Lomaridium, and one of Telmatoblechnum). One species has a circum-Antarctic distribution (plus Mexico), three species have a broadly Neotropical distribution, six species are restricted or almost restricted to South America and one is endemic to Brazil. New records are presented for six species in states from southeastern Brazil, in other regions of the country, as well as in other countries. Taxonomic descriptions, synonymies, lectotypifications, geographical distributions, and comments are presented for all genera and species occurring in the study area. We also give keys for the identification of Brazilian genera of Blechnaceae and for species of the genera treated here.

Three New Species

Three new species of Cypella are described and illustrated for the complex of grasslands ecosystems of Rio de La Plata: C. aurinegra, C. guttata and C. ravenniana. The former is endemic to the region of the Taquari river, southern Cerro Largo Department, Uruguay, and is closely related to Cypella fucata and C. luteogibbosa, but can be distinguished from these species by its yellow flowers stained with dark-purple, narrower outer tepals, smaller inner tepals, shorter adaxial crests of style branches, slender filaments, and seeds with smooth testa. Cypella guttata occurs in Artigas and Rivera Departments, northern Uruguay, and in Santana do Livramento Municipality, southwestern Rio Grande do Sul State, Brazil. This species resembles C. herbertii and C. lapidosa, and can be distinguished by its flowers with central depression showing red spots, filaments narrower and tape-shaped, style branches with shorter adaxial crests, and small transverse stigmatic surface of the abaxial crest. The range of geographic distribution of C. ravenniana includes southern Misiones, and northeast Corrientes Provinces, Argentina, and west and northwest Rio Grande do Sul State, Brazil. This species can be recognized by its one-flowered spathes, borne on short peduncles. Cypella ravenniana was firstly misidentified as C. suffusa; however, having as base the type and topotypical collections of the latter species, C. suffusa is recognized by its two-flowered spathes borne on long peduncles, and perigone golden-yellow with deep central concavity. Data about phenology, geographic distribution, conservation and dichotomous keys to segregate these three new species from its related species are supplied.
