Abstract:

Abstract The Nationally Determined Contributions (NDCs) to the Paris Agreement (PA) submitted so far do not put the world on track to meet the targets of the Agreement and by 2020 countries should ratchet up ambition in the new round of NDCs. Brazil’s NDC to the PA received mixed reviews and has been rated as “medium” ambition. We use the Brazil Land Use and Energy System (BLUES) model to explore low-emission scenarios for Brazil for the 2010–2050 period that cost-effectively raise ambition to levels consistent with PA targets. Our results reinforce the fundamental role of the agriculture, forest, and land use (AFOLU) sectors and explore inter-sectoral linkages to power generation and transportation. We identify transportation as a prime candidate for decarbonization, leveraging Brazil’s already low-carbon electricity production and its high bioenergy production. Results indicate the most important mitigation measures are electrification of the light-duty vehicle (LDV) fleet for passenger transportation, biodiesel and biokerosene production via Fischer-Tropsch synthesis from lignocellulosic feedstock, and intensification of agricultural production. The use of carbon capture and storage (CCS) as well as netzero deforestation make significant contributions. We identify opportunities for Brazil, but synergies and trade-offs across sectors should be minded when designing climate policies.

Abstract:

ABSTRACT Beards are an indication that man has reached maturity. It is with this idea in mind that the songs from the second album by artist Baco Exu do Blues, Bluesman, are analyzed. At the early age of 22, in his act of creation, Baco criticized the conditions of socioeconomic inequality and racism imposed on people of African descent, acting as an ideological sign in the construction of a Black Consciousness. As a symbol of insurgency, Baco also used mythical language to compose an identity and format his rap, creating a hero. Hip hop criticizes racial capitalism, established in Brazil with the colonization and the arrival of enslaved Africans. The compositions are analyzed as cries of resistance to necropolitics – a call to perform acts that relate ethical values and poetry when doing politcs.

Abstract:

Rock e política se enamoram desde o surgimento do gênero em meados da década de 1950, aliás, as “raízes” do rock and roll, como o blues, rhythm & blues, country e western já traziam motes da política. E no caso do denominado rock nacional dos anos 80 e sua ligação com a política não foi diferente. Desse modo, este artigo busca tratar historicamente da relação entre rock e política, ou seja, interpretar versos e acordes que ressoaram na acústica nacional entre arpejos e timbres de desesperanças com um futuro promissor do país, como na canção O adventista, da banda Camisa de Vênus; a descrença com o movimento estudantil retratada na canção Fé nenhuma dos Engenheiros do Hawaii; e o vazio político e a falta de ideologia representada pela canção Ideologia, de Cazuza.

Abstract:

During the reproductive season Blue-black grassquit (Volatinia jacarina) males are found in clusters, wherein they exhibit a distinctive display that consists of repeated, vertical leaps while simultaneously producing a brief vocalization. The main objective of this study was to describe details of the species' reproductive behavior in a "Cerrado" area of central Brazil and compare these data with some studies carried out in other areas. The data obtained concerning different aspects of nesting, laying and hatching were generally similar to those obtained in previous studies in other areas. However, we found that the typical clutch size of two eggs per nest is lower, and egg and nestling mortality rates higher in our area than what has been reported elsewhere. Our results suggest that males differ in time expended with different activities according to their reproductive condition and also provide extensive parental care. We found that display execution rates peak in the early morning and in the late afternoon and are higher in the middle of the breeding season. We also found that there is an inverse relation between the height of the display leap and the height of the perch.

Abstract:

Stomachs from 222 blue sharks collected along the Brazilian coast were analyzed - 116 from the northeastern region and 106 from the southern region. A total of 51 prey taxa were identified. The most important prey items in the southern region were Mysticeti whales, teleosteans, the gempylid Ruvettus pretiosus and the nomeid Arioma bondi. Cephalopods were more diverse, with dominance of vertical migrants Histioteuthis spp., Cranchiidae and the epipelagic octopus Ocythoe tuberculata. In the northeastern region, blue sharks consumed mainly teleosteans, including the alepisaurid Alepisaurus ferox and the gempylid Gempylus serpens. Among cephalopods, Histioteuthis spp. and the epipelagic octopus Tremoctopus violaceus were the dominant items. Predation upon schooling prey was occasional, as observed on Arioma bondi. Birds also were consumed in both regions; Puffinus gravis was the fifth most frequent item in the northeastern region. During the reproductive migration cycle, blue sharks likely prey in the thermocline, which is deeper in the northeastern region and closer to the surface in the southern region.

Geophagy is a habit recorded for parrots, which seek earthy or soil-like substances presumably to help them in digestive functions, whether mechanical or chemical ones. Few studies are devoted to this feeding peculiarity in the Pantanal region. Here are reported two events of geophagy, for the Blue-and-yellow Macaw (Ara ararauna) and the Nanday Parakeet (Aratinga nenday) in the Pantanal subregions of the Miranda-Abobral and Nhecolândia, Mato Grosso do Sul, respectively.

Abstract:

Two new species of the genus Melanorivulus are herein described from the middle Rio Verde drainage, upper Rio Paraná basin, Mato Grosso do Sul, Brazil. Both new species are members of the Melanorivulus pictus clade, diagnosed by having ventral process of angulo-articular vestigial and flanks intense greenish blue or greenish golden to purplish blue above anal fin base in males. Melanorivulus nigropunctatus, new species, from wetlands of a small drainage tributary of right side of the Rio Verde, differs from all other congeners by possessing black dots over the head and body in both sexes and pectoral fin orange with a dark grey margin in males. Melanorivulus ofaie, new species, is found in a similar environment, but at the opposite margin of the Rio Verde. It is distinguished by males presenting flank greenish blue to light blue, with seven to nine oblique chevron-like red bars, ventral portion of head whitish with dark brown spots, dorsal fin yellow with two to three transverse broad red oblique stripes and distal region red, anal fin light orangish yellow, basal area light blue with short red bars and distal portion with a dark red margin, and caudal fin yellow or orangish yellow with three to four vertical red bars in the dorsal and middle portions, sometimes with a orange distal margin. Both new species are considered endangered due to the loss and degradation of their habitat.

Abstract:

AbstractBrumadoite, ideally Cu3Te6+O4(OH)4-5H2O, is a new mineral from Pedra Preta mine, Serra das Eguas. Brumado, Bahia, Brazil. It occurs as microcrystalline aggregates both on and, rarely, pseudomorphous after coarse-grained magnesite, associated with mottramite and quartz. Crystals are platy, subhedral. 1—2 μm in size. Brumadoite is blue (near RHS 114B), has a pale blue streak and a vitreous lustre. It is transparent to translucent and does not fluoresce. The empirical formula is (Cu2.90Pb0.04Ca0.01)Σ2.95 (Te0.936+Si0.05)Σ0.98O3.92(OH)3.84.5.24H2O. Infrared spectra clearly show both (OH) and H2O. Microchemical spot tests using a KI solution show that brumadoite has tellurium in the 6+ state. The mineral is monoclinic, P2/m or P21. Unit-cell parameters refined from X-ray powder data are a 8.629(2) Å, b 5.805(2) Å, c 7.654(2) Å,β 0 103.17(2)°, F 373.3(2) Å3, Z= 2. The eight strongest X-ray powder-diffraction lines [d in Å,(I),(hkl)] are: 8.432,(100),(100); 3.162,(66),(2̄02); 2.385,(27),(220); 2.291,(12),(l̄22); 1.916,(11),(312); 1.666,(14),(4̄22,114); 1.452,(10),(323,040); 1.450,(10),(422,403). The name is for the type locality, Brumado, Bahia, Brazil. The new mineral species has been approved by the CNMNC (IMA 2008-028).

Abstract:

Morphological characters and phylogenetic trees generated by analyses of segments of two mitochondrial genes cytochrome b and cytochrome c oxidase I support recognition of three new species of the ‘Geophagus’ brasiliensis species group from coastal basins of northeast Brazil. All new species were diagnosed by exclusive morphological characters and exclusive nucleotide transformations. Geophagusrufomarginatus sp. n., from the Rio Buranhém Basin, is distinguished from all other species of the group by dorsal-fin lappets with red edges, the presence of longitudinal series of small light blue spots between the anal-fin spines and rays, and non-denticulated gill-rakers; it is closely related to G.brasiliensis and G.iporangensis. Geophagusmultiocellus sp. n., from the Rio de Contas Basin, is distinguished from all other species of the group by having small pale blue spots with minute bright blue dots at their centres, that are often vertically coalesced to form short bars on the caudal fin. Geophagussantosi sp. n., from the Rio Mariana Basin, is distinguished from all other species of the group by having blue stripes parallel to the dorsal and anal fin rays on their longest portions. Geophagusmultiocellus and G.santosi belong to the same clade of G.itapicuruensis. The clade composed by the Rio Paraguaçu Basin species was recovered as the sister group of the other species of the ‘G.’ brasiliensis species group.

Abstract:

In the present study, a cluster analysis, in relation to the species composition of the catches, was used to classify 6,486 fishing sets by a longline fleet based in São Paulo State, Brazil, from 1998 to 2006. Based on the proportions of 12 species and three broader species groups, three clusters were identified: C1: other fishes; C2: blue shark; C3: swordfish. Results indicated that the fleet targeted mainly blue shark and swordfish and also showed that the blue shark importance in this fishery has been growing progressively trough the years. Offshore areas were exploited mainly in the first and fourth quarters (from 2001 mainly), while the fishing effort was more concentrated near the continental shelf break, during the second and third quarters (for the whole period). The longline fishery based in Sao Paulo State changed fishing strategy to target different species which produced important changes in catch-per-unit-effort (CPUE) of the main species caught. Cluster analysis seems to have appropriately identified these changes over time, which is an important information, often missing in logbooks.

Abstract:

Wheat, corn and rice crops in Brazil use seeds treated with systemic insecticide/nematicide carbofuran, mixed to rhodamine B red dye. Carbofuran is toxic and rhodamine B is attractive to wild birds that eat up these seeds, resulting in notable mortality during planting. A field experiment was performed in southeast Brazil to evaluate if camouflaged seeds would be less consumed by wild birds in comparison to commercial seeds with red-colored rhodamine B and aposematic blue seeds. Camouflaged seeds were less removed than seeds with rhodamine B and natural colors. The camouflaging was more effective in the presence of irregularities and litter. There was no removal of blue-colored seeds. As legislation requires treated seeds to receive a different color to avoid accidents with humans, camouflaging may be used as replacement of rhodamine B to reduce mortality rates of wild birds.

PeerJ 7 (October 14, 2019): e7780. http://dx.doi.org/10.7717/peerj.7780.

Full text

Abstract:

The native range of the blue crab Callinectes sapidus spans Nova Scotia to northern Argentina. In the US, it constitutes a keystone species in estuarine habitats of the Atlantic coast and Gulf of Mexico (GOM), serving as both predator and prey to other species, and also has historically represented a multi-billion dollar fishery. Knowledge relevant to effective management and monitoring of this ecologically and economically important species, such as levels of population genetic differentiation and genetic diversity, is necessary. Although several population genetics studies have attempted to address these questions in one or more parts of its distribution, conflicting results and potential problems with the markers used, as well as other issues, have obscured our understanding on them. In this study, we examined large-scale genetic connectivity of the blue crab in the US, using 16 microsatellites, and genotyped individuals from Chesapeake Bay, in the US Atlantic, and from nine localities along the US GOM coast. Consistent with the high long-distance dispersal potential of this species, very low levels of genetic differentiation were detected for the blue crab among the ten US localities examined, suggesting it constitutes a large panmictic population within this region. Estimations of genetic diversity for the blue crab appear to be high in the US, and provide a baseline for monitoring temporal changes in this species. Demographic analyses indicate a recent range expansion of the US population, probably during the Holocene. In addition, capitalizing on published microsatellite data from southern Brazil, our analyses detected high genetic differentiation between localities in the US and Brazil. These results point to the need for examination of genetic diversity and differentiation along the area spanning the US to southern Brazil.

Abstract:

ABSTRACT Brazil is the largest producer and exporter of sugarcane in the world, and the sugar and ethanol sector has invested in the development of new technologies and methods of planting to meet the market demand. Thus, the aim of this study was to evaluate the performance of sugarcane at the acclimation phase and under field conditions, from pre-sprouted seedlings exposed to supplementary lighting, through light-emitting diode, in the period of acclimation in a greenhouse. The experiment was carried out in Carpina, PE, Brazil, from January to September 2017. The experimental plots were composed of pre-sprouted seedlings acclimated in greenhouse, exposed to the supplementary lighting systems, 90% Red + 10% Blue (R:B 90/10), 80% Red + 20% Blue (R:B 80/20), 70% Red + 30% Blue (R:B 70/30) and a control. The evaluation of seedling growth was performed through the measurement of biometric indicators: plant height (cm); stem length (cm); stem diameter (cm) and number of tillers. The biometric indicators showed no significant differences, but plants under lighting systems with a greater proportion of the red wavelength (R:B 80/20 and R:B 90/10) showed higher percentage of survival in the field.

Abstract:

Lagoa Santa, a small town in southeastern Brazil where naturalist Peter Lund lived, is regarded nowadays as an important historical site for the biological sciences. From 1847 to 1855, J.T. Reinhardt, hosted by Lund, collected 343 bird species. This material is an outstanding reference for many modern ornithological studies. The present paper reports the occurrence of some rare and threatened birds for the region of Lagoa Santa between 1998 and 2005. In this account I list the Rusty-margined Guan Penelope superciliaris Temminck, 1815; the Roseate Spoonbill Platalea ajaja Linnaeus, 1758; the Maguari Stork Ciconia maguari (Gmelin, 1789); the Wood Stork Mycteria americana Linnaeus, 1758; the Black Hawk-eagle Spizaetus tyrannus (Wied, 1820) and the Turquoise-fronted Parrot Amazona aestiva (Linnaeus, 1758). It is also reported the southernmost record for the Blue-and-yellow Macaw Ara ararauna (Linnaeus, 1758) and the range extension of the Crowned Slaty flycatcher Griseotyrannus aurantioatrocristatus (d'Orbigny and Lafresnaye, 1837). These data can be used as a baseline for studies of colonization and extinction.

Abstract:

Abstract In the presente study, cluster analysis was performed to classify 1080 interviews with captains of national pelagic longline fleet (2000 to 2011), and 38 trips of the chartered fleet (2003 to 2008), in relation to the composition of species landed. For the national fleet 4 groups were identified: 1 - Albacores, 2 - Blue shark, 3 - Swordfish, and 4 - Dolphinfish. For the chartered fleet 3 groups were identified: 1 - Swordfish, 2 - Blue shark, and 3 - Albacores. The results indicated that part of the national fleet change their strategies according to the availability of the target species and market demand (internal and external). A part of the fleet from Espírito Santo state operates in the region between December and March, exclusively to capture dolphinfish. The chartered fleet differed from the national one as regards the fishing areas of each target species, mainly as regards swordfish and blue shark. Despite the great difference in the data sets, it is evident that both the national and the chartered fleets operated in accordance with their peculiarities and technological development, adopting strategies that optimize catches and net profits per trip.

Abstract:

Habitat use by the Little Blue Heron (Egretta caerulea) and discovery of feeding territoriality are discussed here. The results showed the existence of a territorial individual defending an area (2,564.46 ± 943.56 m²) close to the mangrove, and non-territorial individuals (9.17 ± 2.54) in the rest of a demarcated area (mean area for the non-territorial: 893.25 ± 676.72). A weak positive correlation (r = 0.47, df = 46, p < 0.05) was found between the overlapping of territorial and non-territorial individuals (2.85 ± 3.07 m²) and the mean overlapped area for territorial individuals (171.41 ± 131.40 m²). Higher capture (1.52 ± 1.14 × 1.00 ± 1.37 catches/minutes) and success rates (0.45 ± 0.31 × 0.21 ± 0.27) and lower energy expenditure rates (45.21 ± 14.96 × 51.22 ± 14.37 steps/minutes; and 3.65 ± 2.55 × 4.94 ± 3.28 stabs/minutes) were observed for individuals foraging in areas close to the mangrove. The results suggest that the observed territorial behaviour is more related to a number of food parameters than to intruder pressure, and also that the observed territoriality might be related to defense of areas with higher prey availability.

Abstract:

Dahlstedtia Malme (Leguminosae) is a neotropical genus, native to the Brazilian Atlantic Forest, and comprises two species, D. pinnata (Benth.) Malme and D. pentaphylla (Taub.) Burk., although it has been considered a monotypic genus by some authors. Leaf anatomy was compared to verify the presence of anatomical characters to help delimit species. Foliar primordium, leaflet, petiolule, petiole and pulvinus were collected from cultivated plants (Campinas, SP, Brazil) and from natural populations (Picinguaba, Ubatuba and Caraguatatuba, SP, Brazil - D. pinnata; Antonina, PR, Brazil - D. pentaphylla). Studies on leaflet surface assessment (Scanning Electron Microscopy), as well as histology and venation analyses were carried out of dehydrated, fresh and fixed material from two species. Leaflet material was macerated for stomatal counts. Histological sections, obtained by free-hand cut or microtome, were stained with Toluidine Blue, Safranin/Alcian Blue, Ferric Chloride, Acid Phloroglucin. Secretory cavities are present in the lamina, petiolule, petiole, pulvinus and leaf primordium in D. pentaphylla, but not in D. pinnata, and can be considered an important character for species diagnosis. Other leaf characters were uninformative in delimiting Dahlstedtia species. There is cambial activity in the petiolule, petiole and pulvinus. This study, associated with other available data, supports the recognition of two species in Dahlstedtia.

Abstract:

When I first arrived in Salvador, Brazil in 1991, I stayed with the relatives of friends I had made in Amsterdam. This family lived in a very poor part of Penambuas, itself a poor neighborhood at the periphery of Salvador. An open sewer ran in front of the house. This sewer, in turn, emptied out into an even larger sewer at the bottom of the hill. The toilet of my hosts did not work, but at least they had a house (largely because of money sent from Amsterdam). Their neighbor's home consisted of rubble piled to make unstable walls topped by a roof of broken boards. At the bottom of the hill, next to the larger sewer, young children, who seemed to have no parents, lived in a makeshift tent of tom blue plastic. Despite the daily scrubbing that the daughters of my hosts gave to their own house, cockroaches lived happily on the bathroom walls and in the kitchen cupboards, while rats lurked under the washing trough. The children from the blue tent begged daily at the door for food.

Growth rate and the photosynthetic pigments chlorophyll a, chlorophyll c, carotenoids and phaeopigments were measured under white, blue and red light of the same intensity (8 and 20 µE.cm-2.s-1). Growth rate increased under blue light while red light increased chl a concentration. The relative proportion of chl a and carotenoids did not change, demonstrating the absence of complementary chromatic adaptation.

Abstract:

O título abre um panorama largo e complexo. Sugere o vôo alto de uma águia no céu azul por cima das montanhas. Mas homem maduro é prudente, até cauteloso. Sabe que não tem asas para voar. Ao menos no centro do Brasil, o pássaro que voa nas alturas não é águia. É urubu. Em vez de ficar sonhando ou querendo voar como um grande pássaro de asas largas, toda iniciativa humana moral começa com os seres humanos, como são, onde estão pisando na terra e quais possibilidades eles têm para responder às chamadas de Deus e às necessidades dos próximos. Fazer uma radiografia da contextualização do referido apelo moral e de suas possibilidades, no Brasil, hoje, é objeto do ensaio do Autor.Abstract: The title opens a large and complex panorama. It suggests the flight of an eagle, high up in the blue skies above the mountains. But the mature man is prudent, even cautious. He knows he has no wings and cannot fly. At least in the brazilian hinterland the bird flying high is not the eagle but the vulture. Instead of day-dreaming or hoping to fly like a large bird with huge wings, we must remember that every moral human initiative begins with the human beings as they actually are, on the ground where they stand and with the possibilities they have of answering God’s summons and to his/her fellow beings’needs. The objective of the Author’s essay is to take an X-ray of the context of this moral appeal and the possibilities of its realization in contemporary Brazil.

En el poema narrativo Song for Anninho, Jones combina música, poesía y oralidad para reconstruir -por medio de la imaginación y de hechos históricos, y desde un punto de vista femenino que incorpora los significados modernos del blues- la memoria de resistencia del Quilombo de Palmares, un conjunto de asentamientos de esclavos fugitivos fundados en el nordeste de Brasil a comienzos del siglo XVII. Así, este poema épico es, en realidad, una canción híbrida que, cantada por una mujer, vincula a Brasil y Estados Unidos a través de la diáspora y la esclavitud.

Abstract:

Entimus serpafilhoi, a new species of the weevil genus Entimus from southeastern Brazil is described. It is distinguished from other species of the genus because it lacks the green, blue and gold iridescent scales typical of most other species. Superficially this species is similar to E. arrogans, which also lacks such scales, but the phylogenetic analysis shows it to be more closely related to E. excelsus and E. nobilis. The new species inhabits the ‘restinga’ forest, in contrast to other species from the state of Rio de Janeiro (Brazil) that are found in the Atlantic forest further from the coast.

Pulp and paper secondary waste-treatment systems in Brazil, Canada, New Zealand, and the U.S.A. contained dynamic cyanobacterial communities, some of which exceeded heterotrophic bacterial biomass. No other viable photoautotrophic populations were detected in the ponds. Regardless of geographical location, Oscillatoriales including Phormidium, Geitlerinema, and Pseudanabaena were the dominant taxa. As well, Chroococcus (Chroococcales) was an important genus in Brazil and New Zealand. The possible impact of cyanobacteria on waste-treatment efficiency deserves further study given their large biomass and diverse metabolic characteristics.Key words: cyanobacteria, blue-green algae, heterotrophic bacteria, community structure, pulp and paper secondary waste treatment.

Abstract:

It is well known that crystals of topaz from the Eastern Brazilian Pegmatite Province may turn blue by the irradiation with60Co gamma rays followed by heat treatment. Also, it is known that the sensation of color changes with the thickness of these crystals. The dependence of the color, given by 1931 CIE chromaticity coordinates, with the thickness of the crystal was analyzed. The absorbance used in the calculation of these coordinates was given by the sum of Gaussian lines. The parameters of these lines were determined through the decomposition of the optical absorption spectra in the ultraviolet and visible regions. The decomposition revealed several lines, whose assignment was made considering studies in spodumene and beryl crystals and highly accurate quantum mechanical calculations. The transmittance becomes very narrow with increasing thickness, and the CIE chromaticity coordinates converge to the borderline of the CIE Chromaticity Diagram at the wavelength of maximum transmittance. Furthermore, the purity of color increases with increasing thickness, and the dominant wavelength reaches the wavelength of maximum transmittance.

Abstract:

In this study the floral biology, breeding system, visitors and pollinators of Paliavana tenuiflora were analyzed in campos rupestres in the Chapada Diamantina, Mucugê, Bahia, Brazil. Paliavana tenuiflora is a shrub with blue-violet, bell-shaped flowers, with anthesis at 11:00 h; the flowers last about six days. Large amounts of nectar are produced (volume average 15.5µL, concentration 22.7% and sugar content 5.0 mg mL-1). The amount of nectar is not related to the time of day, but concentration varied with volume. The species is self-compatible, but fruit set depends on pollinators. Although nectar is available by day and night, flowers of P. tenuiflora fit the bee pollination syndrome, and are actually pollinated by Bombusbrevivillus. However, the hummingbird Phaethornis pretrei can be considered an occasional pollinator, due to its behavior and low frequency of visits. Our results suggest a mixed pollination system, although the importance of P.pretrei as a pollinator remains to be better evaluated.

A comparative study was performed with five samples of palygorskite from different locations through ore dressing and chemical and mineralogical characterization, using the XRD, XRF and methylene blue titration techniques. According to the results, there are significant differences in the samples composition. Among them, the most significant difference was the cation exchange capacity (CEC) value, which ranged from 24.0 to 41.0 meq.100 g-1, followed by the content of some oxides and the crystalline phases present. Despite coming from the same region, the samples contained distinct impurities.

Para este fim, inicialmente, constroem-se variáveis relacionadas às taxas de acidentes do trabalho (fatal, lesão e doença) para as subclasses da Classificação Nacional de Atividades Econômicas (CNAE) e estima-se a função de salários hedônicos para diferentes amostras de trabalhadores separadas por gênero e grau de risco da ocupação juntamente com o cálculo do valor estatístico de uma vida (VSL), de doenças e de lesões para cada amostra. Os resultados mostram que para os homens em geral, o VSL é de R$2,442 milhões, enquanto para os homens blue-collars este valor é de R$1,119 milhão. Para as mulheres em geral, o VSL obtido é de R$1,088 milhão, porém, para as mulheres blue-collars os resultados obtidos não permitiram inferências a respeito. Ademais, constata-se que o VSL médio calculado para o Brasil está muito abaixo do obtido para a maioria dos países, inclusive dos países em desenvolvimento.

Abstract:

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.
