Description of two new species of Ischyroceridae (Crustacea: Amphipoda) from the coast of Southeastern Brazil

Abstract: Taxonomic descriptions and figures are provided for 2 new species of Ischyroceridae (Cerapus jonsoni sp. nov. and Notopoma fluminense sp. nov.) from samples of Southwestern Atlantic, between the latitudes 22° and 24° S. Cerapus jonsoni sp. nov. is easily distinguished from others species of the genera recorded in Atlantic Ocean by dacyli of pereopods 6 and 7 with 1 accessory spine. Notopoma fluminense sp. nov. is characterized by 5 setal teeth on outer plate of maxilla 1, only 1 accessory spine on pereopod 7 d… Show more

“…Therefore, these characters should be taken with caution. Considering that the specimens of L. baconi recorded by Bousfield & Hoover (1997) and Valério-Berardo & de Souza (2009) were lacking robust setae in article 4 of male antenna 2, Gouillieux & Sauriau (2019) suggested that they could correspond to L. bifurcatum instead of L. baconi. While specimens of the introduced range studied in the present work fit within the original and subsequent description of L. baconi from native and exotic ranges, variability in the robust setae in article 4 of antenna 2 was observed.…”

“…Navarro-Barranco et al (2022) confirmed an established population of the species in New South Wales, reaching very high densities in Chowder Bay, Sydney. In 2001, L. baconi was recorded from Rio de Janeiro, Brazil (Valério-Berardo & de Souza, 2009;Serejo & Siquiera, 2018). In 2006, it was collected from the hull of a boat at Opua, New Zealand (McFadden et al, 2007;Ahyong & Wilkens, 2011).…”

“…As espécies de Hyalidae que ocupam os sistemas aquáticos de baixas latitudes apresentam um padrão de reprodução com períodos reprodutivos extensos (SAINTE-MARIE, 1991). A população natural de P. hawaiensis estudada apresentou dois períodos reprodutivos mais importantes, um mais curto no final do outono/inverno e outro mais longo no final da primavera e período de verão, como constatado para diversas espécies litorâneas no sudeste brasileiro (VALÉRIO-BERARDO; FLYNN, 2004). Este comportamento é explicado pela variação latitudinal da temperatura que permite a produção de duas ou mais gerações por ano nas baixas latitudes (CUNHA et al, 2000).…”

“…Várias espécies do grupo são adequadas ao cultivo e manipulação experimental devido as estratégias de vida que apresentam, tais como: produção continuada de ovos ao longo da vida, embriões disponíveis o ano inteiro, e pelo fato de exibirem o comportamento de amplexo copulatório, facilitando assim a determinação dos casais em cópula. Por essas características, o grupo tem sido utilizado em estudos ecológicos no sudeste brasileiro, englobando estudos de biologia reprodutiva (JACOBUCCI; LEITE, 2006;LEITE, 1996aLEITE, , 1996bLEITE, e 2002 e dinâmica populacional (VALÉRIO-BERARDO; FLYNN, 2002FLYNN, , 2004FLYNN et al, 2008;FLYNN et al 2009;PEREIRA, 2013).…”
