A new species of Hyalella (Crustacea, Amphipoda, Dogielinotidae) from the Atlantic Forest of Misiones, Argentina

Abstract

The freshwater genus Hyalella Smith, 1874 has a distribution restricted to the Western Hemisphere with most species being found in South America. In this report we describe a new species of Hyalella from the Atlantic Forest of the Misiones province, Argentina.

Population structure of two freshwater amphipods (Crustacea: Peracarida: Hyalellidae) from southern Brazil

“…The genus Hyalella Smith, 1874 is distributed in the Nearctic and Neotropical biogeographic regions; it is endemic from the Americas, and its species have a restricted distribution (Bousfield, 1996). The genus includes approximately 72 species (Baldinger, 2004;Colla and César, 2015;Streck et al, 2017;Bastos-Pereira et al, 2018.). Hyalella is found in a variety of freshwater environments, attached to aquatic macrophytes, swimming in the water column, or buried in the sediment (Kruschwiyz, 1978;Wellborn, 1995;Grosso and Peralta, 1999).…”

“…Information concerning ecological features of freshwater crustaceans are scarce, especially those with the order Amphipoda. In the last few years, understanding of American's Hyalella has risen with an increasing number of taxonomic publications, indicating that there is still a large number of species unknown to science (González and Watling, 2002a, 2002b, 2003a, 2003bBaldinger, 2004;Pereira, 2004;González et al, 2006;Cardoso et al, 2011;Bueno et al, 2013;Rodrigues et al, 2014;Cardoso et al, 2014;Colla and César, 2015). In Brazil, most studies of Hyalella concern new species descriptions (Bastos- Pereira and Bueno, 2013;Bueno et al, 2013;Cardoso et al, 2014;Bueno et al, 2014;Streck et al, 2017), however, knowledge on their life cycles, population biology e reproductive biology are limited by the studies of Castiglioni and Bond-Buckup (2008a) (Hyalella castroi González, Bond-Buckup andAraujo, 2006 andHyalella pleoacuta González, Bond-Buckup andAraujo, 2006), Castiglioni et al (2016) (Hyalella bonariensis Bond-Buckup, Araujo and Santos, 2008) and Ozga and Castiglioni (2017) Streck and Castiglioni, 2017).…”

A new species of freshwater amphipod (Crustacea, Amphipoda, Hyalellidae) from state of Rio Grande do Sul, Southern Brazil

“…The Family Hyalellidae is represented only by Hyalella Smith, 1874, which occurs throughout the Nearctic and Neotropical biogeographic regions, and it is endemic of the Americas (Baldinger 2004), presenting restrict distribution of species (Bousfield 1996). There are 74 limnic crustacean species of Hyalella (Marrón-Becerra et al 2014;Colla and César 2015;Streck et al 2017;Bastos-Pereira et al 2018), however the highest diversity of species occurs in South America, where 56 species are currently described (Rodrigues et al 2014, Colla andCésar 2015;Streck et al 2017;Bastos-Pereira et al 2018).…”

First record of the genus Hyalella (Amphipoda: Hyalellidae) from Santa Catarina State, Brazil, with description of two new species

“…South America bears almost 80% of the diversity of the genus (Rodrigues et al 2014;Colla & César 2015;Streck et al 2017;Bastos-Pereira et al 2018;Streck-Marx & Castiglioni 2019), yet only less than a third of the ecological studies with the genus deals with its southern species. There are 76 species described (Bueno et al 2019;Streck-Marx & Castiglioni 2019), 28 of which are from Brazil (Rodrigues et al 2014;Streck et al 2017;Bastos-Pereira et al 2018;Peralta & Isa Miranda 2019;Streck-Marx & Castiglioni 2019).…”
