Procyon cancrivorus is a wild animal that is found from Central America to Uruguay and northeastern Argentina. It is one of the least studied carnivore species in Brazil. For the purpose of identifying helminths that parasitize P. cancrivorus, individuals of this species that had been run over and killed by motor vehicles were collected from highways in the southern part of the state of Rio Grande do Sul. At necropsy, their organs, along with organ contents and mucous membranes, were examined for parasite collection. The nematodes found in the stomachs of these Procyonidae were cleared with lactophenol and Chandleronema longigutturata was identified. This report provides the first record of occurrences of C. longigutturata in the Neotropical region and its parasitism in P. cancrivorus.

A New Species

Abstract: A new species of the genus Temnocephala Blanchard, 1849 from southern Brazil was found on two species of anomuran crustaceans, Aegla spinipalma Bond-Buckup & Buckup, 1994 and Aegla grisella Bond-Buckup & Buckup, 1994, the latter classified as a vulnerable species by the "Lista de Referência da Fauna Ameaçada de Extinção no Rio Grande do Sul. Decreto no 41.672, de 11 junho de 2002". The crustaceans were collected from a tributary creek of the Forqueta river, Perau de Janeiro, Arvorezinha and a tributary creek of the Fão river, Pouso Novo, Rio Grande do Sul, Brazil; both localities belong to the Sub-Basin of Forqueta River. The new species differs from seven other temnocephalans epibionts on Aegla Leach, 1820, by having the following characters: 1. a long and slightly curved cirrus, 2. two vaginal sphincters, one proximal, big and asymmetric, and one distal, smaller and symmetric, and; 3. longer than wide, elongated epidermal 'excretory' syncytial plates (EPs), with a almost horizontally central excretory pore, displaced to the anterior portion of the plate. The new species' EP is the largest in total length among epibionts temnocephalans in crustaceans already registered. Regarding the similarities with the male reproductive system of Temnocephala axenosMonticelli, 1898, the new species has important differences in the female reproductive system. It has a larger proximal vaginal sphincter, located in the middle of the vagina, while the smaller distal one is at the extreme end of the organ. Besides that, the vaginal portion between the proximal and distal sphincters is conspicuous, with a strong muscular wall. This is the first record of a species of Temnocephala in the Taquari Valley, as well in the 'Perau de Janeiro', which is an area with a rich endemic fauna.

Three New Species

New data about slender orb-weaving species of the cosmopolitan genus Tetragnatha are presented. Tetragnatha chauliodus (Thorell, 1890) and Tetragnatha tenuissima O. Pickard-Cambridge, 1889 are redescribed, including one synonymy for each species and the first record of the first species to the Neotropical region. Also, three new species are herein described, all based on males and females. Tetragnatha megalocera new species is recorded exclusively from Brazil (Espírito Santo, Rio de Janeiro, Rio Grande do Sul and São Paulo states), while Tetragnatha renatoi new species is recorded from Venezuela, Argentina (Misiones) and Brazil (Paraná, Pernambuco, Rio Grande do Sul, Rondônia, Santa Catarina and São Paulo states). Finally, Tetragnatha chiyokoae new species is described from Yunnan province (China) and Okinawa (Japan), with an additional record for Taiwan. Furthermore, Tetragnatha exilima (Mello-Leitão, 1943), Tetragnatha filigastra Mello-Leitão, 1943 and Tetragnatha lactescens (Mello-Leitão, 1947) are nomina dubia.

New Host Record

The species Amblyomma longirostre Koch, 1844 is poorly known in the state of Rio Grande do Sul. Usually the adult stage could be found on Sphigurus spp. and the immatures on birds (Passeriformes). Although A. longirostre is distributed in the Neotropical region, from Panama to Uruguay, it also occurs in Central America and the United States. The aim of this study was to report that Ramphastos dicolorus Linnaeus 1766 is a new host record for this tick species.

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.

Rhipicephalus Sanguineus Sensu Lato

Rhipicephalus sanguineus, the brown dog tick, is responsible for maintaining and transmitting various pathogens, both in animals and human beings, and it is of great sanitary importance. This communication reports the first occurrence of Rhipicephalus sanguineus sensu lato parasitizing Rattus norvegicus in the state of Rio Grande do Sul, Brazil, and it is also the first record of this tick species parasitizing Rattus rattus in Brazil. The rodents were captured from the port area, located in the city of Pelotas, Rio Grande do Sul, Brazil. We collected 6 larvae of this tick species from 2 male R. rattus individuals, and 3 larvae from 2 female R. norvegicus individuals; parasitized specimens of both rodent species were captured from different sites within the experimental area. This record broadens the number of Rhipicephalus sanguineus sensu lato hosts in urban areas, indicating the need for continued monitoring on population density for both R. sanguineus and synanthropic rodents.

An analysis of bivalves shells collected off the coast of Rio Grande, Rio Grande do Sul, Brazil and specimens of scientific collections, identified as Cuspidaria braziliensis E. A. Smith, 1915 was made. From the examination of syntypes of C. braziliensis and the type species of the genus Plectodon Carpenter, 1864, a redescription was made and it is proposed to transfer the species to the genus Plectodon, resulting in the new combination Plectodon braziliensis (E.A. Smith, 1915). This is the first record of a Plectodon species for the South Atlantic.
