The Brazilian expeditions Revizee and Oceanprof collected samples from the southwest Brazilian coast between depths of 200 and 2200m. These expeditions sampled eleven species ofOplophoridae, ten of them new records for Southwestern Atlantic: Oplophorus gracilirostris A. Milne Edwards, 1881; O. spinosus (Brullé, 1839); Acanthephyra eximia A Milne Edwards, 1881; A. acutifrons Bate, 1888; A. quadrispinosa Kemp, 1939; A. stylorostratis (Bate, 1888); Ephyrina benedicti Smith, 1885; Janicella spinicauda (A. Milne Edwards, 1883); Notostomus elegans A. Milne Edwards, 1881; Systellaspis debilis (A. Milne Edwards, 1881) and S. pellucida (Filhol, 1885). The specimens are described and figured.
La superfamille des Coronuloidea de la côte brésilienne est révisée. Elle inclut 16 espèces ou sous-espèces réparties en deux familles et 8 genres. La famille des Coronulidac comprend 12 espèces ou sous-espèces: Chelonibia caretta, C. patula, C. testudinaria, Coronula diadema, C. reginae, Xenobalanus globicipitis, Playlepas decorata, P. hexastylos hexastylos, P. h. ichthyophila, Platylepas sp., Stomatolepas elegans, S. transversa. La famille des Tetraclitidae comprend: Tetraclitella divisa, Newmanella radiata, Tetraclita stalactifera stalactifera et T. s. floridana. La taxonomie, l'habitat dans l'Atlantique sud-occidental et la distribution de ces espèces sont discutés. Les caractères diagnostiques des sous-familles des Platylepadinae et des Coronulinae ont été analysés et il est apparu que la première sous-famille est un groupe artificiel. La formation du test est comparée chez Platylepas et Stomatolepas; ce dernier genre est révisé et les espèces sont redécrites.
A B S T R A C TThe adult of Scalpellopsis striatociliata and the ontogeny of its capitular and peduncular plates are described. During ontogeny, S. striatociliata develops the carino-lateral (CL) and inframedian (L2) plates heterochronously after some peduncular plates (cl), which is unique. The position of Scalpellopsis as sister-group of the other scalpellids is reaffirmed. The Scalpellidae have diverse peduncular plate patterns, with the 8-plated pattern being ancestral and the most widespread among the genera. The peduncular plate patterns of several species of Scalpellidae are presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
