First Report of <i>Temnocephala brevicornis</i> Monticelli 1889 (Temnocephalidae: Platyhelminthes) in Argentina

Temnocephala brevicornis Monticelli 1889, ectosymbiont of Hydromedusa tectifera Cope 1869, is reported for the first time for Argentina. Numerous temnocephalans from Arroyo Villoldo in the locality of Magdalena, Buenos Aires, Argentina were stained in toto to be studied. This commensal species in turtles was originally cited in association with Hydromedusa maximiliani (Mikan) and Hydraspis radiolata Mikan in Brazil. Afterwards, it was found on other fresh water turtle species in Brazil and Uruguay.Facultad de Ciencias Naturales y Muse

Se identificaron varios lotes de diferentes regiones de Argentina. Para cada lote se proporciona la siguiente información: localidad de colección georeferenciada, colector y fecha de recolección, número de colección, los datos de la etiqueta (transcriptos con exactitud de la redacción original), observaciones y el mapa de las localidades geográficas.We present here a catalog of the Trichodactylidae (Crustacea, Brachyura) deposited in the Crustacean Collection of Museo de La Plata, Argentina. Eighty lots were studied, comprising eight species. Among these lots, many had been characterized by R. Ringuelet and by C. Magalhães; several lots from different regions of Argentina were identified. For each lot the following information is provided: georeferenced locality of collection, collector and collecting date, collection number, labelling data (a precise transcription of the original wording), remarks, and map of the locations.Facultad de Ciencias Naturales y Muse

A South American bioinvasion case history: Limnoperna fortunei (Dunker, 1857), the golden mussel

Two factors combine in this age of globalization to favor the establishment of alien species in natural environments: human activities and global climate change. This paper reviews the recent invasion of the golden mussel, Limnoperna fortunei, in South America, including its impacts in natural and human environments. This case study allows the identification of the likely impacts that morphologically and functionally similar invasive species will have in similar environments, such as in North America, which is considered to be at high risk of invasion by L. fortunei.Fil: Darrigran, Gustavo Alberto.

Ecosystem engineering impact of Limnoperna fortunei in South America

Limnoperna fortunei, or golden mussel, has invaded aquatic ecosystems in the Americas following it introduction from Southeast Asia. It is not only an aggressive invasive species, it is also a very effective ecosystem engineer, altering both ecosystem structure and function, and causes great ecological and economic impacts. This paper describes its impact as an ecosystem engineer (on benthic communities and the water column). A review of the existing scientific literature is presented, and the impact and the mechanisms by which the golden mussel modifies, maintains, and creates new environmental conditions in the invaded South American inland freshwater environments are analyzed. Understanding the ecosystem engineering roles of L. fortunei is important for its management and/or control in the invaded areas, and in cases of future invasions.Fil: Darrigran, Gustavo Alberto.

Type and non-type specimens of Aegla (Decapoda: Anomura: Aeglidae) housed in the Museo de La Plata, Argentina

The present contribution deals with the type and non-type material of the species of Aegla (Decapoda: Anomura: Aeglidae) deposited in the Invertebrate Collection of Museo de La Plata, Argentina. One hundred and thirty-four lots are included, of which 10 lots are type specimens. The material examined includes 11 of the 13 species known from Argentina. Among the studied lots, those examined by Ringuelet (1948, 1960) and by Bond-Buckup & Buckup (1994) stand out. Also, several lots from different regions of Argentina were identified. Type specimens examined were compared with the original descriptions; photographs of the specimens are given in the present report. For each lot the following information is provided: georeferenced locality of collection, collector and collecting date, bibliographical references, category, number of collection according to the rules of the Museo de La Plata, label data (precise transcription), remarks and map of the locations.Fil: César, Inés Irma.

Checklist of free-living microturbellarian flatworms (Turbellaria, Platyhelminthes) in the Suquía River Basin, Córdoba, Argentina

Free-living microturbellarians are a part of lentic and lotic aquatic assemblages and play an important but underestimated role in aquatic ecosystems. Consequently, they are not included in studies on the dynamics of freshwater aquatic invertebrate communities. We report eight new records of microturbellarians from the Suquía River (Córdoba, Argentina): Catenula lemnae Dugès, 1832, Stenostomum arevaloi Gieysztor, 1931, Stenostomum aff. amphotum Marcus, 1945, Macrostomum aff. quiritium Beklemischev, 1951, Macrostomum platensis Adami, Damborenea & Ronderos, 2012, Microstomum sp., and Mesostoma erhenbergii (Focke, 1836). We discuss these results within the geomorphological history of the river basin.Fil: Adami, Mariana Laura. Universidad Nacional de La Plata. Facultad de Ciencias Naturales y Museo.

A taxonomic revision of South American species of the genus Stenostomum O. Schmidt (Platyhelminthes: Catenulida) based on morphological characters

This paper revises the genus Stenostomum based on a rich collection of species from Argentina and on a review of bibliographical resources of all known South American species. The description of South American species is standardized. The new genus Anokkostenostomum is established and several species of Stenostomum are transferred to it based on the absence of light-refracting bodies and the presence of a metameric anterior brain lobe. We report five Stenostomum species and three Anokkostenostomum species new to Argentina and present an identification key for South American species. Finally, all the world species are compiled, with an overview of their distribution.Facultad de Ciencias Naturales y Muse
