This is the first record of cercariae of Monascus filiformis (Rudolphi, 1819) and of Chaetognatha as a secondintermediate host in the southwest Atlantic Ocean. The morphology of the sporocyst and cercaria from Nucula obliqua (Bivalvia:Nuculidae) and a full description of the metacercaria from hydromedusae are given. The life cycle of M. filiformis involves threehosts. The bivalve N. obliqua is the first intermediate host, Chaetognatha and medusae are the second intermediate hosts, and thejurel Trachurus lathami (Pisces: Carangidae) is the final host. The life cycle of M. filiformis occurs in shallow waters in theArgentine Sea and differs from Køie’s experimental scheme for the North Sea in the addition of planktonic invertebrates assecond intermediate hosts. The life cycle proposed here follows the general pattern given for the family Fellodistomidae.

New Habitats

The introduction of non-indigenous marine species in new habitats is generally associated with ships arriving at ports, driven by species transported in ballast water and sediment and biofouling communities on ship hulls, drifting object and underwater surfaces in dock areas. The present paper reports the record of the specie Sternaspis aff. nana in the Atlantic Ocean, discussing its possible conservation status and method of arrival to Brazil. Sediments samples were collected in the external area (11 m depth) of the Suape Harbor (Brazil) in February 2018. Two individuals of Sternaspis aff. nana were recorded, representing the first record of this species in the Southwest Atlantic Ocean. The way S. aff. nana arrived in Brazilian waters cannot be easily determined, the short-lived lecithotrophic larvae of sternaspids suggest that the specimens found in Suape have arrived in ballast sediment. An increase in trade between Brazil and Asian countries since the 2000s has led to that more ships coming from China having arrived in Brazilian harbors. The arrival of S. aff. nana, originally described in the South China Sea, in the Suape harbor area may have resulted from this intense movement of ships between China and Brazil.

Substrate Use

The present study analyzed and compared diet and feeding behavior (substrate use, position in water column, interactions with other fishes) of Kyphosus spp. (sea chubs) in a Brazilian subtropical reef. Juveniles (< 160 mm) of Kyphosus incisor consumed both algae and invertebrates, which were mainly calanoid copepods. Juvenile and small adults of also observed foraging in the water column. We thus provide the first record of omnivory for Kyphosids in the southwest Atlantic Ocean.

In this work we record two species belonging to the polyclad family Pseudocerotidae from the littoral zone of the Península Valdés (Patagonia, Argentina). This is the first record of members of Cotylea and the third of Polycladida from Argentina. The two new records are Phrikoceros mopsus, a species described for Brazil and Colombia and Thysanozoon brocchii, a cosmopolitan species. Morphological features of both species are presented. These two new records contribute to the knowledge of polyclads from Patagonia and to the general understanding of their biogeography in the Southwest Atlantic Ocean.
