Is Copytus Skogsberg, 1939 (Crustacea: Ostracoda) a neocytherideid? <br />With description of a new family and two new species

Abstract

The genus Copytus Skogsberg, 1939 was erected based on C. caligula, recovered from bottom sediments of the South Georgia Island, Antarctica. However, we propose herein that Skogsberg’s species is a junior synonym of Cytherideis laevata Brady, 1880 also collected from Antarctica and, therefore, Copytus laevata (Brady, 1880) becomes the type species. The position of the genus Copytus in the family Neocytherideidae is discussed, and a new family is proposed. In addition, we consider the genus Neocopytus Külköylüoðlu, Colin &amp; Kiliç, 2007 invalid, and some of its species are transferred to Copytus. Finally, two new species of Copytus are herein described, C. cuspidata sp. nov. and C. wuerdigae sp. nov., and their geographic, bathymetric and stratigraphic distributions are discussed.

Paleoecological characterization of ostracods in beachrocks from the Northern sector of the Rio Grande do Sul Coastal Plain, Brazil

“…and Copytus sp. are typically marine (Sanguinetti et al, 1991(Sanguinetti et al, , 1992Aiello et al, 1993;Whatley et al, 1997;Coimbra et al, 2020).…”

Provinciality of Ostracoda (Crustacea) in the Northeastern and Eastern Brazilian shelves based on neontological and paleontological analyses

“…Their faunal survey inspired many other taxonomic and zoogeographical studies, which resulted in the description of taxa typical of warm or temperate waters and a better understanding of the distribution patterns of the Brazilian benthonic shelf ostracods (e.g. Purper & Ornellas, 1987a,b, 1989Coimbra & Ornellas, 1986Ramos, 1994Ramos, , 1996Coimbra et al, 1994Coimbra et al, , 1995Coimbra et al, , 1999aCoimbra et al, ,b, 2004Coimbra et al, , 2020Fauth & Coimbra, 1998;Carmo & Sanguinetti, 1999;Ramos et al, 1999Ramos et al, , 2004Ramos et al, , 2012Ramos et al, , 2014Coimbra & Fauth, 2002;Coimbra & Carreño, 2002;Coimbra & Carmo, 2002;Bergue & Coimbra, 2002;Machado & Drozinsnki, 2002;Coimbra & Bergue, 2003;Aiello et al, 2004;Machado et al, 2005;Luz & Coimbra, 2015;Bergue et al, 2016;Coimbra & Morais, 2016;Morais & Coimbra, 2019).…”
