Abstract
Pseudaeginella montoucheti (Quitete, 1971) is redescribed based on newly collected specimens from red and brown algae and tubiculous polychaete colony that were obtained from shallow waters at Tamboretes Archipelago, Balneário Barra do Sul and Sepultura Beach, Bombinhas, Santa Catarina State, Brazil. Of 10 species of Pseudaeginella so far reported, Pseudaeginella montoucheti is closest to Pseudaeginella sanctipauli Laubitz, 1995, but differs from the latter by having more numerous body spines including ventro-lateral ones over gills on pereonites 3 and 4, and the antenna 1 length measuring half body length. An identification key for Pseudaeginella species and a checklist of Caprellidea occurring along the Brazilian coasts are also presented.
Highlights
The knowledge on ecology and biology of Brazilian caprellids is restricted to some areas and substrata, mainly those living on macroalgae from southeastern and southern coast (Masunari 1982; Dutra 1988; Arenzon and Bond-Buckup 1991; Wakabara et al 1991; Dubiaski-Silva and Masunari 1995; Mittmann and Müller 1998; Jacobucci et al 2002; Jacobucci et al 2006; Leite et al 2007; Dubiaski-Silva and Masunari 2008)
Collections were conducted at two Islands - Pássaros Island (26°22'S, 48°31'W) and Araras Island (26°27'S, 48°34'W) – in Tamboretes Archipelago, municipality of Balneário Barra do Sul (16th May 2009) and at Sepultura Beach, Bombinhas (30th June 2011) Santa Catarina State, southern Brazil
Caprellideans were found in the phytal of the red algae Amphiroa beauvoisii Lamouroux and Spyridia aculeata (Schimper) Kützing, of the brown alga Sargassum cymosum C
