Although around 3,000 species of nudibranchs are known worldwide, only nearly 100 species are reported from Brazil. From Bahia State, northeastern Brazil, only seven species are listed. The current article provides four new records of nudibranchs from this region: Geitodoris pusae (Marcus 1955); Felimida paulomarcioi (Domínguez, García and Troncoso 2006); Felimida binza (Marcus and Marcus 1963) and Cadlina rumia Marcus 1955. The new records presented herein fill part of a historical gap in the species geographic distribution, and increase to eleven the number of nudibranch species known from Bahia.

Abstract:The polyclad Pericelis cata has been reported in two distinct localities along the North Atlantic: Curaçao and the Caribbean coast of Colombia. Recently identified from the Southwestern Atlantic, the species was first described from the Cabo Frio region (23°S) (Rio de Janeiro State), a transitional zone between warm and cold water species located southeastern Brazil. The second location is in the northeastern coast in warm waters, in the entrance of the Todos-os-Santos Bay, a geographic area within the Brazilian Biotic Province, an important center of marine biodiversity of the Tropical Atlantic.

The current article provides the first record of Annulobalcis aurisflamma Simone and Martins, 1995 outside São Paulo state, Brazil. Herein we extend its geographical distribution to northeastern Brazil.

Sea slugs are interesting models to study post-copulatory sexual selection in simultaneous hermaphrodites due to the enormous variation of their reproductive systems. However, the knowledge of the functional morphology of their reproductive system is limited to few species, and it is rarely discussed in the context of sexual selection theory. In this study, we investigated the functional morphology of the spermcontaining chambers (i.e., ampulla, seminal receptacle, and bursa copulatrix) of the reproductive system of Okenia polycerelloides (Ortea & Bouchet, 1983), based on light, confocal, and electron microscopy. Although the morphology of the ampulla is similar to other species, indicating that it is a site for autosperm storage, we found some sperm facing the ampullar epithelium, a feature commonly regarded as characteristic of the seminal receptacle of sea slugs. The seminal receptacle of O. polycerelloides showed secretory activity and contained sperm with distribution and orientation suggestive of stratification of allosperm from distinct mating events, a feature that would affect sperm competition. The bursa copulatrix had epithelial cells with secretory and absorptive characteristics, and contained degraded sperm and yolk granules within its lumen. Comparative analyses of the contents of each organ demonstrated that sperm digestion occurs in the bursa copulatrix and affects sperm heads first, changing their morphology from slender and curved to shorter and ellipsoid before complete lysis. Although digestion and absorption of surplus sperm are currently the main hypothesized functions for the bursa copulatrix, its role in cryptic female choice should not be ruled out. The close structural connection between the seminal receptacle and bursa copulatrix, as well as their muscular walls, would enable control over the fate of the sperm received in each mating event, that is, storage or digestion.

Abstract:The nudibranch Flabellina dana Millen and Hamann, 2006 is reported from two localities in the northeastern Brazilian coast. These are the first records of this species, previously recorded from localities in the Bahamas and the Caribbean Sea, in South Atlantic Ocean, extending its known geographic distribution more than 3500 km southward.
