The occurrence of ephyrae of the scyphozoan orders Semaeostomeae and Rhizostomeae is reported for the first time for the Brazilian coast. The specimens, caught in plankton tows in the São Sebastião Channel and the Cananéia lagoon estuarine system, are: Chrysaora lactea (Semaeostomeae), Phyllorhiza punctata (Rhizostomeae), and an unidentified species of Pelagia (Semaeostomeae). A table with all species of scyphozoan with the known life cycle is provided.

Although the participation of the macromedusae has been relatively low, in areas of elevated concentration, the relative importance was high, making its participation almost exclusive among other zoological groups. Those registers of abundance and the respective areas of high concentration of macromedusae, which were associated to high primary production sites, may serve as a theoretical reference of the abundance of these organisms for future studies that aim to evaluate possible changes in jellyfish populations. Keywords: macromedusae, Rhacostoma atlanticum, Olindias sambaquiensis, bycatch, southern and southeastern Brazil.Evaluación preliminar de la captura incidental de medusas capturadas frente al sur y sureste de Brasil RESUMEN. El registro de formas macromedusoides de las clases Hydrozoa, Scyphozoa y Cubozoa en su hábitat en el sur y sureste de Brasil se efectuó mediante observadores científicos. Después de cada salida de pesca, se cuantificó la composición de la captura y se registró la localización de cada uno de los lances efectuados entre los años 2008 y 2011. El registro de las macromedusas se sistematizó para analizar su distribución espacio-temporal, áreas de concentración y su relación con los demás componentes del descarte de la pesca. El análisis de la captura analizada en 986 lances de pesca mostró que el porcentaje de organismos varió entre 6 y 16%. Las hidromedusas Rhacostoma atlanticum y Olindias sambaquiensis fueron las especies más abundantes y más ampliamente distribuidas. R. atlanticum fue registrada entre 20 y 140 m de profundidad y O. sambaquiensis en aguas más costeras, entre 10 y 70 m. Ninguna otra especie fue registrada en profundidades superiores a 60 m. Las áreas de mayor concentración fueron el litoral centro-norte de Santa Catarina y el litoral de Paraná, sector norte de São Paulo y sector centro-norte de Rio Grande do Sul. A pesar que el porcentaje de estos organismos fue relativamente bajo, en áreas de elevada concentración, la importancia relativa fue alta, y su presencia fue casi exclusivo entre los demás grupos zoológicos. Estos registros de abundancia y las respectivas áreas de alta concentración de macromedusae, asociadas a los áreas de alta producción primaria, pueden servir como referencia teórica de la abundancia de estos organismos para futuros estudios cuyo objetivo sea evaluar los posibles cambios en las poblaciones de medusas. Palabras clave: macromedusas, Rhacostoma atlanticum, Olindias sambaquiensis, pesca incidental, sur y sureste de Brasil.

“…Then, Larson (1986) accomplished the first study covering a wide spatial range reporting the highest number of findings from Antarctic seas up to 30°S but based mainly on the inhabitants of the outer continental shelf and oceanic environments. A few years later, Mianzan published the first systematics and biogeographic account of these taxa, including for the first time neritic species from the Uruguayan and Argentine continental shelves (Mianzan, 1986(Mianzan, , 1989a(Mianzan, , 1989bMianzan et al, 1988). Ten years later, Mianzan & Cornelius (1999) provided the first literature review about the taxonomy and biogeography of these species, including maps of their spatial distribution.…”

“…Despite of being previously reported (Table 2 in Duarte et al, 2012), polyps of C. lactea have been never found in their natural habitat. Although Mianzan (1989a) specifically stated that polyps have not been found in the wild, the presence of ephyrae suggests they should be located nearby at the Bahía Blanca harbor. Interestingly, ephyrae were frequently found only in the Bahía Blanca Estuary and neighboring areas (from October to January; Dutto et al, 2017) but never in the Río de la Plata Estuary (Fig.…”

In this study, we reported the species composition and spatial distribution of Scyphomedusae and Cubomedusae from the southwestern Atlantic and Subantarctic region and reviewed the available knowledge of life history traits of these species. We gathered the literature records and presented new information collected from oceanographic and fishery surveys carried out between 1981 and 2017, encompassing an area of approximately 6,7 million km 2 (32-60°S, 34-70°W). We confirmed the occurrence of 15 scyphozoans and 1 cubozoan species previously reported in the region. Lychnorhiza lucerna and Chrysaora lactea were the most numerous species, reaching the highest abundances/biomasses during summer/autumn period. Desmonema gaudichaudi, Chrysaora plocamia, and Periphylla periphylla were frequently observed in low abundances, reaching high numbers only occasionally. Phacellophora camtschatica, Aurelia sp., Drymonema gorgo, Atolla chuni, Stygiomedusa gigantea and Pelagia cf. noctiluca were observed always in low numbers. Atolla wyvillei, Stomolophus meleagris, Desmonema comatum and Tamoya haplonema were reported just a few times and mostly individually. Although new species/reports can be found as surveys are undertaken, these results are considered to be the reliable baseline for further ecological studies seeking to understand the ecological role that these jellyfish play in marine ecosystems.
