With the aim of creating an inventory of the metazoan gill parasites of Salminus hilarii in the Taquari River, state of São Paulo, Brazil, five species of monogeneans (Anacanthorus contortus,A. bicuspidatus, Annulotrematoides parisellei, Jainus iocensis andTereancistrum arcuatus) are reported the first time for this host. A total of 28 fish were sampled quarterly between April 2011 and January 2012, with 10 hosts in a lentic ecosystem and 18 in a lotic ecosystem. Quantitative ecological descriptors (prevalence, intensity of infestation and abundance) were calculated for the purpose to comparing the two ecosystems sampled (lentic and lotic ecosystems). However, no quantitative difference between the lentic and lotic ecosystems was observed. The present study has made available a checklist for species of the genus Anacanthorus and their hosts and geographical distribution in the Neotropical region up to the present time.

A revision of the genus Eucharitolus Bates, 1885 is presented. Three new species are described from the Neotropical Region: Eucharitolus depressus sp. nov. (Espírito Santo, Brazil), Eucharitolus spilotus sp. nov. (Rondônia and São Paulo, Brazil) and Eucharitolus longus sp. nov. (Madre de Dios, Peru). The geographical distribution of Eucharitolus pulcher is expanded to include Bolivia (Santa Cruz). Leiopus dorcadioides White, 1855 is transferred to Eucharitolus and its geographical distribution is also expanded to include Peru (Junin). A key to species is provided. All the species are illustrated.

The genus Coelinius (Hymenoptera: Braconidae: Alysiinae) is reported for the first time from Brazil and the Neotropical region. The genus occurs in southeastern Brazil, in the states of Minas Gerais, Rio de Janeiro and São Paulo. Four new species of Coelinius are described and illustrated: C. canastra sp. nov, C. itamonte sp. nov., C. kali sp. nov. and C. lux sp. nov.

In the present paper, we described the first record of an epibiont protozoan Epistylis sp. Ehrenberg, 1830 (Ciliophora, Peritrichia) attached to Ergasilus chelangulatus Thatcher and Brasil-Sato, 2008, parasite of Pimelodus maculatus Lacépède, 1803 in Brazil, with electron microscope observations. Fish were collected in Veados River, state of São Paulo and the crustacean Ergasilus chelangulatus being registered for the first time in this river, expanding its geographical distribution in Brazil.

Terrestrial Isopods were sampled in four protected Atlantic Forest areas located in Serra do Mar, state of São Paulo, southeastern Brazil. A total of 2,217 individuals of six species (Atlantoscia sp., Benthana werneri, Pseudodiploexochus tabularis, Pudeoniscus obscurus, Styloniscus spinosus and Trichorhina sp.) were captured in pitfall traps. The exotic species S. spinosus is recorded for the first time for the Americas. Another introduced species, P. tabularis, previously recorded only from the state of Rio Grande do Sul, had its geographic distribution extended to the state of São Paulo. The most abundant isopods in this study belong to an undescribed species of Atlantoscia.

An updated checklist of xylophilous Agaricomycetes from the Brazilian Cerrado showed 127 species, 22 families and nine orders (Agaricales, Atheliales, Auriculariales, Corticiales, Gloeophyllales, Hymenochaetales, Polyporales, Russulales, and Thelephorales). The new list includes new specimens collected between 2009 and 2011 in Reserva Biológica de Mogi-Guaçu, São Paulo State, Brazil, and a revision of material previously known from Cerrado. Twelve species are mentioned for the first time for Brazil and 51 are recorded as new for the Cerrado.

Abstract C. brasiliensis is described and illustrated. Information on the hosts (Podocarpus elatus, P. lambertii and P. neriifolius), geographical distribution (Paraná, Rio Grande do Sul, Santa Catarina and São Paulo, Brazil), dispersal and pathogenicity of C. brasiliensis is presented. Symptoms of the disease caused by C. brasiliensis are described.

Clathrosporium retortum sp. nov., collected on submerged mixed leaf litter samples at Ilha do Cardoso State Park, São Paulo state, Brazil, is described based on morphological and molecular data. The fungus is characterized by forming whitish, dense, subglobose to irregular propagules, hyaline to subhyaline when young, subhyaline to dark brown at maturity, that are formed by densely interwoven conidial filaments with each conidial cell repeatedly branching bilaterally or occasionally unilaterally. Phylogenetic analyses using partial LSU nrDNA sequence data suggest that C. retortum belongs in the Sordariomycetes (Ascomycota) where it forms a well-supported clade with Clohesia corticola in the Sordariomycetidae, but its ordinal or familial placement remains unresolved. Its phylogenetic placement confirms the polyphyletic nature of aeroaquatic fungi like Clathrosporium, as it was distantly related to one available sequence in GenBank named as C. intricatum, the type species, which is phylogenetically related to the Helotiales (Leotiomycetes). However, due to lack of authenticity of the identity of this sequence with the type specimen of C. intricatum, a broad concept of Clathrosporium is tentatively adopted here to accommodate the present fungus instead of introducing a new genus. Beverwykella clathrata, Helicoön septatissimum and Peyronelina glomerulata are recorded for the first time from Brazil. Cancellidium applanatum and Candelabrum brocchiatum are new records for the state of São Paulo.

Electrona risso, a warm circumtropical lanternfish species distributed in all oceans, has been reported in the western Atlantic from Suriname to Southern Brazil. Re-examination of specimens attributed to this species which presumably supported the southernmost record in the western South Atlantic and are available at Museu de Zoologia, Universidade de São Paulo, Brazil, revealed that they were misidentified and are really Electrona paucirastra. As a result, E. paucirastra is reported for the first time in southern Brazil and the distribution of E. risso in the western Atlantic is discussed.

Xanthacrona Wulp, 1899 has been recorded in several countries of South America, but records in Brazil are few. Here, we record Xanthacrona tuberosa Cresson, 1908, Xanthacrona phyllochaeta Hendel, 1909, and Xanthacrona tripustulata Enderlein, 1921 for the first time from Brazil, and provide new records of Xanthacrona bipustulata Wulp, 1899 from the states Acre, Amazonas, Espírito Santo, Maranhão, Mato Grosso do Sul, Pará, Roraima, and São Paulo.

This work presented the inventory of ferns and lycophytes of Jaú, São Paulo state. Sixty-eight species of ferns and one of lycophyte were recorded, distributed in 16 families and 32 genera. The richest families were Pteridaceae and Thelypteridaceae with 15 species each, Polypodiaceae (7spp.), Blechnaceae and Dryopteridaceae (5 spp. each). The most common guild of life form was terrestrial herbs with 57 species, followed by epiphytes (6 spp.), arborescent, aquatic and lithophytes (2 spp. each) and hemiepiphytes and scandents with one species each. The analysis of the geographical distribution showed that 46% of the species (32 spp.) occur in the Neotropics, 20 species occurs in Southern America, eight are endemic of Brazil, five pantropical and four are exotic. This study can further collaborate in the protection and preservation of the few remnants which represent probably the last areas where some species of these groups of plants occurring in the municipality.
