“…The syncytial plates of T. trapeziformis sp. nov., being trapezoidal, are much different than the plates of the seven Neotropical species showed by DAMBORENEA & CANNON (2001) and the three species described from aeglid anomuran crustaceans, belostomatid hemipterans, and trichodactylids of Rio Grande do Sul (AMATO et al 2003. These records for Rio Grande do Sul are the only papers which can be compared to the present report for having used the same techniques to show the DLSPs and mounting cirri laying flat in deF mounting medium, and only T. lutzi has been recorded on trichodactylid crabs but it shows very distinct characters when compared to what is now observed in T. trapeziformis sp.…”

Temnocephala trapeziformis sp. nov., ectosymbiont on Trichodactylus fluviatilis Latreille, 1828 is described from the State of Rio Grande do Sul, southern Brazil. Sixty-eight crabs were examined, of which 61 (89.7 %) were positive for this species of the genus Temnocephala Blanchard, 1849. Eggs, as well as adult and young specimens, were found on the pleural areas of the carapace, in the orbital cavities, and, usually, on the fourth pair of pereiopods. The temnocephalans were always devoid of body pigmentation, although they kept the red eye pigment, undiluted in specimens fixed by hot (90ºC) phosphate buffered 10% formalin. The most distinctive characters of the new species are: 1) the shape and size of the cirrus and the characteristics of its introvert section; 2) the trapezoidal shape of the dorsolateral post-tentacular 'excretory' epidermal syncytial plates, with the nephridiopore in the lower inner corner of the plate; and 3) the number, size, and distribution of the rhabdite producing glands, as observed in very young specimens.

Microturbellarians (Platyhelminthes and Acoelomorpha) in Brazil: invisible organisms?

2016

Microturbellarians typically belong to the benthos and may occur in a wide variety of environments. They are abundant in freshwater and marine ecosystems and may occur in moist terrestrial habitats. However, turbellarians are seldom taken into account in studies of biodiversity. Most studies on Brazilian microturbellarians had taxonomical purposes and were done in the years 1940-1950. Thus, information on their occurrence and ecological aspects are dispersed throughout several papers. We intend here to summarize the biogeographical distribution and ecological aspects of microturbellarians recorded for Brazil, indicating the main gaps in their knowledge and possible actions to enhance studies on this group. There are 239 species of microturbellarians registered for Brazil, with records distributed in 12 states. However, just three states located in southern Brazil have records of 94% of microturbellarian species. Thus, knowledge on the systematics and geographical distribution of Brazilian microturbellarians clearly reflect the scientific activity over many years or decades in two states of southeastern and southern Brazil. Considering the scant information on this group in Brazil, which is also the situation of the Neotropical microturbellarians in general, some actions should be proposed. First, it would be necessary to sample in the diverse biomes, as well as in the various river and sea basins, based on standardized sampling protocols. Second, it would be necessary to encourage diverse research groups to include microturbellarians and/or turbellarians in general into biodiversity inventories and studies on community structure of invertebrates. Third, it is necessary to increase the number of research groups on microturbellarians, in order to augment the studies on their morphology, systematics, and ecology. Considering their abundance, species richness and ecological importance in aquatic environments, despite some peculiarities regarding their sampling, sorting and identification procedures, the challenge to study microturbellarians and enhance knowledge about them in Brazilian ecosystems should be faced.Keywords: Platyhelminthes, species diversity, Neotropical region, systematics, ecology. Microturbelários (Platyhelminthes e Acoelomorpha) no Brasil: organismos invisíveis? ResumoMicroturbelários são tipicamente bentônicos e podem ocorrer em uma ampla variedade de ambientes. São abundantes em ecossistemas marinhos e de água doce, podendo ocorrer em ambientes terrestres úmidos. Entretanto, turbelários raramente são considerados em estudos de diversidade. A maioria dos estudos sobre microturbelários brasileiros tiveram propósito taxonômico e foram realizados nos anos 1940-1950.

“…Besides the validity of the record of Temnocephalida order for the state, not cited by the Biota project (Forneris, 1999a), when contributing to the preservation of this group, Japi streams help to maintain the ecological ectosymbiosis relation between temnocephalida and crustraceans of the Aegla (Amato et al, 2003) and Trichodactylus genera (Amato et al, 2006). Still using the Biota Project FAPESP inventory results (Steiner and Amaral, 1999), Japi Mountain also collaborates for the conservation of freshwater polychaete of the Stratiodrilus Tabanidae Tipulidae Hymenoptera Diapriidae Scelionidae genus, and it is possible to suggest that S. arreliai Amaral & Morgado, 1997 is present in Japi, considering only the distribution information (proximity to Jaraguá peak) and hosts (Aegla sp.…”

Preservation of terrestrial fauna and flora has been the main reason for the settlement of most protected areas in the past 30 years, but although those areas may include water bodies, this does not necessarily mean that the biodiversity of freshwater environments are also protected. In the present study, the fauna inventory of eight streams (1 st , 2 nd , 4 th and 5 th orders) of three microbasins of Japi Mountain, a Biosphere Reserve of Atlantic Forest recognised by UNESCO since 1994, located in São Paulo state, southeast of Brazil, was conducted. The hypothesis of this study is that the conservation of this area is important for the maintenance of the aquatic biodiversity of this biome, and so, this world hotspot deserves priority conservation actions. From 2005 to 2007, benthic macroinvertebrates, fishes and, eventually, anuran amphibians were sampled in these streams. The results showed that Japi Mountain contributes to the conservation of 138 taxonomic units of the aquatic biota and covers a rich and representative biodiversity of freshwater fauna of the world (0.2%), Neotropical region (0.9%), Brazil (2.4%) and São Paulo state (17.9%). The studied streams in the Environmental Protection Area help protect endangered taxa like the fishes Neoplecostomus paranensis and Pareiorhina cf rudolphi, and shelter freshwater invertebrates and fishes whose distribution is restricted to the Brazilian territory. Japi Mountain is also an important haven of species that was missing there like the frog species Vitreorana eurygnatha. Thus, this species inventory emphasises the importance of conservation actions of the freshwater environments of this Biosphere Reserve of Atlantic Forest.Keywords: amphibians, freshwater, fish, invertebrates, protected areas. A importância de uma Reserva da Biosfera da Mata Atlântica para a Conservação da Fauna de Riachos ResumoA conservação da fauna e flora terrestres tem sido a principal razão para o estabelecimento da maioria das áreas protegidas nos últimos 30 anos, porém, apesar de muitas destas áreas apresentarem corpos d'água, isto não significa necessariamente que a biodiversidade dos ambientes dulcícolas também estará protegida. No presente trabalho foi realizado o levantamento da fauna de oito riachos (1ª, 2ª, 4ª e 5ª ordens) de três microbacias da Serra do Japi, localizada no estado de São Paulo e reconhecida como Reserva da Biosfera da Mata Atlântica pela UNESCO desde 1994. A hipótese do estudo é de que a conservação desta área seja de grande importância para a manutenção de sua biodiversidade aquática, comprovando assim a necessidade de ações prioritárias de conservação deste bioma.
