The genus Jaspis comprises 32 valid species, six of which were previously recorded from the Atlantic Ocean. Two species have already been recorded from the Brazilian coast: J. johnstonii and J. salvadori (Rio Grande do Sul and Espírito Santo States respectively). Their respective type specimens, deposited at Muséum National d'Historie Naturelle, Pa...

... Regarding the Potiguar Basin, some new species have been described in the last decade (i.e., 16 new species/ records-see Supplementary File) and studies have continued to be published over the years (e.g., Barros et al. 2013;Carvalho et al. 2013;Domingos et al. 2013;Cavalcanti et al. 2014aCavalcanti et al. , 2014bCavalcanti et al. , 2015aCavalcanti et al. , 2015bCavalcanti et al. , 2018Santos et al. 2014bSantos et al. , 2016Lira & Pinheiro 2015;Neto et al. 2018;Dias et al. 2019Dias et al. , 2023, demonstrating that we are still uncovering this fauna. These recent studies played a crucial role in developing our updated list of marine sponge species from RN, which is important for filling the gaps in Wallacean and Linnean shortfalls. ...
The Brazilian spongiofauna is still one of the least known worldwide, and the Northeastern region of Brazil is the one with the greatest recorded diversity. Previous studies on sponges in the Rio Grande do Norte State focused on deeper regions of the Potiguar Basin and oceanic islands, lacking any records from intertidal environments. The present study aimed to investigate the biodiversity of marine sponges from two beaches on the northern coast of Rio Grande do Norte. The specimens were collected in intertidal beachrocks of Baixa Grande and Ponta do Mel beaches (Areia Branca, RN) quarterly between August 2018 and May 2019, using the active search method for 2 hours during low tide. We identified 19 species belonging to the Demospongiae class, four taxa were considered dominant and six were considered rare according to the sampling period. Our study considerably improved the knowledge of the spongiofauna for the Rio Grande do Norte State, with six new taxa occurrences: Placospongia sp., Dysidea robusta, Haliclona (Reniera) manglaris, Haliclona (Reniera) tubifera, Haliclona (Soestella) caerulea and Amorphinopsis atlantica. Additionally, we present an updated checklist of marine sponge species
from RN, including location, coordinates, and geographic distribution details.
Three new isomalabaricane-type terpenoids, jaspiferins H (1), I (2), and J (3), were isolated from the marine sponge Jaspis stellifera collected from the South China Sea. The structures of the new metabolites were elucidated on the basis of extensive spectroscopic methods.
