Lagostas são valiosos recursos pesqueiros na costa nordeste do Brasil. No estado de Pernambuco, as capturas das lagostas vermelha (Panulirus meripurpuratus) e verde (Panulirus laevicauda) foram elevadas, enquanto as da lagosta sapata (Scyllarides brasiliensis), reduzidas. Neste artigo, as variações mensais e anuais das capturas foram analisadas nos desembarques das três espécies entre 1999 e 2006. De maneira geral, a lagosta vermelha foi predominante. As capturas das lagostas vermelha e da verde decresceram rapidamente a partir do início da temporada de pesca, logo após o defeso, padrão esse não observado para a lagosta sapata. As capturas anuais provenientes das embarcações de comprimento pequeno ou intermediário foram maiores que as das embarcações de maior porte. São José da Coroa Grande, seguida do Recife, foi a cidade em que se verificaram as maiores quantidades desembarcadas. Houve zonação espacial no que diz respeito às proporções das três espécies nas capturas anuais. A lagosta vermelha foi amplamente dominante nas capturas da costa sul, onde a sapata não foi incomum. Na costa norte, a lagosta sapata foi rara, e a proporção de lagosta verde foi alta e similar à da lagosta vermelha.(AU)
Lobsters are valuable fisheries resources in the northeast coast of Brazil. In the Pernambuco state the catches of the red (Panulirus meripurpuratus) and the green (Panulirus laevicauda) spiny lobsters are high, while the catches of the slipper lobster (Scyllarides brasiliensis) is low. In this study the variability of the monthly and annual catches of those three species were analyzed with data obtained between 1999 and 2006. Overall the red lobster predominates in the catches. Catch of the red and the green lobsters decrease quickly starting from the beginning of the fishery after the closed season, but this do not occur for slipper lobster. Total annual catches of small or intermediate length boats were higher than summed catches of large boats. São José da Coroa Grande, followed by Recife, is the city with highest catches. There was spatial zonation concerning the proportions of the three species in the annual catches. The red lobster is largely dominant in the catches of the south coast, where the slipper lobster is not uncommon. In the north coast catches the slipper lobster are rare and the proportion of green lobster is high and similar to the proportion of the red lobster.(AU)

The only specimen listed in the original description of Scyllarides deceptor Holthuis, 1963 is the holotype from São Paulo, Brazil, presently housed in the Leiden Museum. From the original description, however, it is clear that the new species was actually based on a number of additional specimens. Six of them exist in the collections of the Museum of Zoology in São Paulo, and are shown herein to be paratypes of S. deceptor. Scyllarides deceptor and S. brasiliensis Rathbun, 1906, continue to be confounded with one another, in consequence of their very similar color patterns and locally sympatric distributions. As many as 251,786 tons of slipper lobsters have been landed in Santa Catarina between 2000 and 2007. These catches have been attributed to S. deceptor alone and did not take into consideration the existence of a second species in the area, S. brasiliensis. Correct recognition of slipper-lobster species will be critical to properly evaluate the lobster stocks in southeastern Brazil. An opportunity is taken herein to elaborate on the taxonomy of S. deceptor and S. brasiliensis.
