“…Curtis (1991) reported that only one species of freshwater turbellarian, Mesostoma brincki Marcus 1970, had been positively identified from Namibia. In a comprehensive global collation of turbellarian species with Gondwanan affinities, Noreña et al (2003) (Böhmig, 1914)) from the region, but did not indicate how many of these occur in temporary wetlands. Houben et al (2014) reported P. foliacea from a temporary pond in Hluhluwe Game Reserve, SA.…”

“…The discovery of these new species in the Pacaya-Samiria National Park in Peru suggests the existence of a high diversity of turbellarians in this area, which up to now has remained largely unknown, and increases the general knowledge of the fauna of Neotropical turbellarians (Noren˜a et al 2003). Although such a diversity has gone unnoticed, we expect it to be one of the highest in South America.…”

Two New Rhabdocoels (Platyhelminthes) from the Peruvian Amazon Floodplain

Two new Rhabdocoel species from the Peruvian Amazonia are described: Sergia calae n. sp. (Dalyelliidae) and Mesostoma ucamara n. sp. (Typhloplanidae). Both species were captured in the Pacaya-Samiria National Park, Loreto, Peru, with plankton-nets dragged several times through the abundant littoral floating plant-community. This is the first record of micro-turbellarians in this region. The discovery of these new species in the Pacaya-Samiria National Park suggests the high diversity of this area, which up to now has remained largely unknown, increases the general knowledge of the fauna of Neotropical turbellarians.

“…Em ambientes límnicos, os macroturbelários incluem representantes de Tricladida e os microturbelários, de Catenulida, Macrostomida, Prolecithophora, Lecithoepitheliata, Proseriata e Rhabdocela (Young 2001). Segundo Noreña et al (2003), das 510 espécies de microturbelários citadas para as regiões do Gondwana, mais de 45% foram registradas no Brasil.…”

Turbellarians occur in a variety of wetlands, being also abundant in temporary water bodies. Several turbellarians are top predators in their microhabitats, many of them feeding on zooplankton. However, they are seldom taken into account in biodiversity studies. Information on turbellarian diversity in Brazilian freshwater ecosystems mainly came from taxonomical studies. In southern Brazil, there are a high number of wetlands, most of them represented by rice fields. Despite their impact on natural areas, these managed ecosystems can play an important role in freshwater biodiversity conservation. The aim of the present work was to report on an inventory done in irrigated rice fields of three areas of the Coastal Plain of southern Brazil, viz. Cachoeirinha, Santo Antônio da Patrulha e Camaquã. We found 144 species of freshwater turbellarians, distributed in six taxonomic groups (Catenulida, Macrostomida, Lecithoepitheliata, Proseriata, Rhabdocoela, and Tricladida). Twenty-three species are recorded for the first time for Brazil. Catenulida showed the highest relative abundance in Cachoeirinha, followed by Rhabdocoela. In Santo Antônio and Camaquã, Tricladida had the highest relative abundance, followed by Catenulida. Results suggest that some turbellarian species show a high level of habitat specificity with only 38% of the registered turbellarians occurring in a single study area. Although there is a paucity of turbellarian inventories in Brazilian natural wetlands, hampering a comparison between natural and managed wetlands, results indicate high species richness in the areas studied. Resumo: Os turbelários são encontrados em uma grande variedade de hábitats aquáticos, sendo abundantes inclusive em áreas úmidas temporárias. Diversos turbelários são predadores de topo nos seus microhabitats, muitos deles alimentando-se de zooplâncton. No entanto, raramente os turbelários são considerados em inventários de diversidade. Informações sobre sua diversidade nos ecossistemas límnicos brasileiros provêm principalmente de estudos taxonômicos. No Rio Grande do Sul, há um grande número de áreas úmidas, sendo a maioria delas representadas por lavouras de arroz. Esses ecossistemas manejados, embora tenham alto impacto sobre áreas naturais, podem exercer um importante papel na conservação da biodiversidade aquática. Este estudo teve por objetivo inventariar os turbelários ocorrentes em áreas de cultivo de arroz irrigado de três localidades da Planície Costeira do sul do Brasil (Cachoeirinha, Santo Antônio da Patrulha e Camaquã). Foram registradas 144 espécies de turbelários, distribuídas em seis grupos taxonômicos (Catenulida, Macrostomida, Lecithoepitheliata, Proseriata, Rhabdocoela e Tricladida). Vinte e três espécies são registradas pela primeira vez para o Rio Grande do Sul. Catenulida apresentou a maior abundância relativa em Cachoeirinha, seguida por Rhabdocoela, enquanto nas outras duas localidades, a maior abundância relativa foi de Tricladida, seguida por Catenulida. Os resultados sugerem que algumas espéci...
