The Araneidae is a speciose family including web-spinning spiders that are very abundant in various terrestrial ecosystems. Sixty-five araneid species from 20 genera were collected during an inventory of riparian forests in southern Brazil. Among these were one new species, described here as Mangora piratini sp. nov. Also discovered were the previously unknown males of Alpaida citrina (Keyserling, 1893), A. octolobata Levi, 1988 and Testudinaria lemniscata (Simon, 1895), which are described here for the first time. Metazygia floresta Levi, 1995, Ocrepeira malleri Levi, 1993 and Testudinaria quadripunctata Taczanowski, 1879 are recorded for the first time for Rio Grande do Sul State, Brazil.

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.

A New Species

A new species of triadal coralsnake (Micrurus) is described from Rio Grande do Sul, Brazil. The new species differs from other Micrurus species in southern Brazil by the following characters: snout mostly black, head completely black, white gular region, triads with middle black ring 1.5 to 2 times longer than the external black rings, white rings shorter than the external black rings.  The new species occurs sympatrically with M. altirostris and adds to the following known triadal species for the region: M. baliocoryphus, M. pyrrhocryptus, M. lemniscatus, and Micrurus decoratus. Its current range is restricted to Rio Grande do Sul but it may reach adjacent areas of Argentina and Paraguay.

(A new species of Graphis [Graphidaceae: Lichenized Ascomycota] and a revised key of the genus in Rio Grande do Sul, southern Brazil). In this paper we describe a new species of the lichen genus Graphis, namely G. suzanae Koch & Feuerstein. This species is characterized mainly by lirellae with entire labia, a partially exposed disc with orange pigment in the epithecium, a lateral thalline margin, a laterally carbonized excipulum, a clear hymenium, and transversely septate ascospores measuring 40–44 × 8–10 μm. The chemistry of the species was assessed through TLC analysis. A complete key with G. suzanae and 56 more species of Graphis that where previously recorded to the state of Rio Grande do Sul, southern Brazil, is included.

A New Species

AbstractA new species of Pseudis is described from São Francisco de Paula, Rio Grande do Sul, Brazil. It is known from the southern parts of the Serra Geral where it occurs in grassland, inhabiting permanent ponds and still-water zones of slow flowing creeks. It is characterized by a paired vocal sac and a bulbous thumb, considerably widened at the base. It is distinguished from P. minutus by its different call, body coloration, rounded snout, and a more robust body with shorter hindlimbs. Advertisement call, tadpole, and life history are described. The taxonomy of the family Pseudidae in Rio Grande do Sul is discussed, supporting the synonymy of Lysapsus mantidactylus and P. meridionalis with P. minutus.

The Resthenini genus Opistheurista has been known until now by the single species O. clandestina, which occurs in the Nearctic region. While studying mirids from Rio Grande do Sul, Brazil, we found a female exemplar as a new species. We provide descriptions, diagnoses, illustrations, and a key to distinguish the two species of genus Opistheurista.
