Abstract: This study aimed to present a checklist of marine fishes from coastal environments of the Island of Santa Catarina, including comments on the zoogeographic affinities, conservation status of each species, and functional groups. A total of 169 fish species belonging to 30 orders and 58 families were recorded. The most speciose families were Sciaenidae, Carangidae and, Engraulidae, representing 26,62% of the recorded species. Anchoa was the richest genus, followed by Sphoeroides and Cynoscion. Most of the species have their distribution limited to the western Atlantic, and two groups of fish were distinguished according to the species distributions: 1) species occurring in the Caribbean and in the Brazilian Province; and 2) Transatlantic species. Thirteen species are critically threatened, 10 are overexploited on the Brazilian coast, and 2 are threatened by extinction. Most of the species are either marine stragglers or marine migrants, and most of them are zoobenthivores, piscivores, or both.

A New Species

A new species of Gastrophanella, G. cavernicola sp. nov. (Demospongiae: Siphonidiidae), is described from submarine caves in Fernando de Noronha Island (north-east Brazil), Carrie Bow Cay and Columbus Cay, Belize (central Western Atlantic), at depths of 5-30 m. It differs from all other species of the genus by its lobate shape with thin superficial canals and centrotylote tylostrongyles. Gastrophanella cavernicola sp. nov. is the second record of the genus Gastrophanella from both Brazil and the Caribbean. It is the sixth ‘lithistid’ sponge reported from the Brazilian coast, whereas at least 32 other desma-bearing sponges are known from the Caribbean. The genus now includes five valid species, G. implexa Schmidt from the West Indies (type species), G. mammilliformis Burton from South Africa, G. primore Gómez from the Pacific Coast of Mexico, G. stylifera Mothes & Silva from south Brazil, and G. cavernicola sp. nov. from north-east Brazil and Belize. Aciculites oxytylota Lévi & Lévi from New Caledonia is transferred to Siphonidium Schmidt. The family Siphonidiidae Lendenfeld, which is probably related to order Hadromerida, is redefined to contain only Siphonidium and Gastrophanella, both with fused rhizoclone desmas associated to microspined exotyles.

The island of Santa Catarina lies in the Atlantic Forest Domain of southern Brazil, one of the most threatened ecosys tems on the planet. It holds a wide variety of habitats, ranging from sand dune ‘restingas’ to mature rain forest. We report, for the first time, a survey of the bird species and their conservation status for the different habitats present on the island. We recorded 269 bird species of 54 families (25 species were seabirds). More than 50% (140) of the total number of species were residents or probable residents, 20% (58) were visitors and a relatively high number of species (61, 23%) had indeterminate residential status. Nearly 15% (35 species) of the 244 landbird species observed were endemic to the Atlantic Forest. Habitat specificity was recorded for 40% (97 species). We recorded one Endangered (Solitary Tinamou Tinamus solitarius), one Vulnerable (White-necked Hawk Leucopternis lacernulata), and three Near-threatened species (Azure Jay Cyanocorax caeruleus, Azure-shouldered Tanager Thraupis cyanoptera, Black-backed Tanager Tangara peruviana). We also recorded six locally threatened species that we predict will become extinct in the near future. The future for the birds of the island is uncertain, especially for habitat specialists, due to habitat loss for resort developments, and a lack of concern by the government and local people.

Senecio reitzianus was described from sand dunes in Lagoa da Conceição (Florianópolis, Santa Catarina state, southern Brazil). The species remained to be known only from the type. Almost seventy years later, we discovered a population of this species in Costão do Santinho, about 20 km from the type locality. A detailed account of this population is provided and its conservation status is assessed. We also present photographs of this species from the wild and also of the holotype, as well as a new description and comparisons with similar species in the genus. Our results reinforce the urgent need of further field work, especially on data-deficient species, in order to have a chance to prevent the species extinction.

A new species of the genus Tambja is described from the western Atlantic on the coast of Brazil. To date, the genus Tambja was represented in the Atlantic Ocean by nine species but only three of them have been recorded from the western Atlantic: T. gratiosa from the Gulf of Mexico, T. divae from Brazil and T. oliva from the Caribbean coast of the Isthmus of Panama. Tambja stegosauriformis sp. nov. is easily distinguished from all its congeneric Atlantic species of the genus by having very well developed light blue tubercles scattered on the yellowish-orange ground with an elongate crest behind the gill until the end of the tail. The anterior margin of the notum is very wide and elevated and it extends into a kind of lapel around the rhinophores. This peculiar external morphology and its conspicuous coloration characterize this species.

Unknown Species

Despite the increasing number of reports on the deep-sea molluscs from the south-western Atlantic, we know very little about the protobranchs. The lack of information on the protobranch Pelecypoda off southern Brazil is reflected in the genusYoldiella. This contribution is part of an effort to increase the knowledge about this group off the Brazilian coast. Eight species ofYoldiellaare recognized here. ForYoldiella biguttata, previously reported from Brazil, the known distribution is extended southwards to the Campos Basin. ForYoldiella similisthis is the first record in the western Atlantic Ocean. ForYoldiella extensaandYoldiellaaff.jeffreysithis is the first record for Brazil. Four previously unknown species are described,Yoldiella lapernoisp. nov.,Yoldiella paranapuaensissp. nov.,Yoldiella arariboiasp. nov. andYoldiella curupirasp. nov. Considering only conchological features for the Atlantic species we could propose some clusters of species ofYoldiella.

The genus Rhinoptera is composed of eight species widely distributed in tropical, subtropical and temperate coastal waters, which inhabit bays, estuaries and river mouths. Cownose ray Rhinoptera bonasus has been reported to inhabit the Western Atlantic including the Gulf of Mexico and the Caribbean, whereas the Brazilian cownose ray R. brasiliensis has been considered endemic to the coast of Brazil. Recent reports of R. brasiliensis in the Gulf of Mexico bring about the question of whether the species has a wider range than previously reported. Here, the mitochondrial genes COI, Cytb, NADH2 and the nuclear gene RAG1 were used to distinguish among species and to confirm the presence of R. brasiliensis in the Gulf of Mexico. R. brasiliensis specimens collected along the southern Gulf of Mexico showed a remarkable genetic and morphological affinity when compared with R. brasiliensis specimens from Brazil, supporting the presence of the species in Mexico (from Veracruz through Campeche) and providing evidence that its distribution ranges from Brazil to the Caribbean Sea and the Gulf of Mexico. Both species overlap geographically to a large degree, leading to a reassessment of their conservation status. Our results also show that R. bonasus distribution in the Gulf of Mexico may be restricted to the northern portion, in US waters.

A regional marine reservoir correction (ΔR) of 33±24 14C yr for southern Brazil was obtained from 6 marine shell samples collected in the states of Santa Catarina and Paraná. This work also presents a ΔR estimation of 8±17 14C yr for the southern and southeastern Brazilian coast from the states of Rio de Janeiro to Santa Catarina, obtained by including 7 ages published in previous works. The high variability of R in modern and Holocene samples from the Brazilian coast is also discussed.

Doris verrucosa Linnaeus, 1758 is the type species of Doris, the type genus of Dorididae. Its currently accepted distribution includes the Mediterranean, Eastern (Europe and Africa) and Western Atlantic (Massachusetts, USA to Santa Catarina, Brazil). Until now, papers on the anatomy of this species dealt with restricted characters such as rhinophores, radula and reproductive organs, never comparing specimens from different localities. In this study we have examined the anatomy of species similar to D. verrucosa from the Brazilian coast, and compared them with samples of D. verrucosa from Europe, the type locality. After an extensive complementary anatomical study of the circulatory, excretory, digestive, reproductive and nervous systems, the identity of the Brazilian specimens is clarified, proving that they belong to a different species. To solve the consequent nomenclatural gap, we revalidate Staurodoris januarii Bergh, 1878, described from Brazil, transferred to the genus Doris. The nominal species Doris verrucosa is, therefore, restricted to European waters.

This article presents and describesPlantago humboldtiana, an extremely narrow endemic rheophytic new species from a waterfall in Corupá, Santa Catarina state, southern Brazil. The new species is unique in presenting a combination of type-G antrorse trichomes on scapes, pendulous inflorescences and 1-seeded pyxidia. Only one population is known to exist, despite intensive search efforts in nearby, similar environments. Its conservation status is assessed as critically endangered (CR) as the only known population is restricted to a dramatically small area, and is subject to extreme fluctuation due to occasional floods, and also to intense visitation by tourists, which can disturb its fragile habitat. We also present an updated identification key to the species ofPlantagothat occur in Santa Catarina. The recent description of three narrow endemic, threatened new species ofPlantagoin Santa Catarina, which is the Brazilian state with its flora best studied, highlights the need for more taxonomic research, especially in the neotropics.
