REGISTRO DE OCORRÊNCIA DO Hoplosternum littorale (HANCOCK, 1828) (SILURIFORMES: CALLICHTHYIDAE) NA BACIA DO RIO SALGADO NO SUL DO CEARÁ-BRASIL

The current paper had as objective to record the occurrence of H. littorale in the Salgado River basin, Juazeiro do Norte municipality, in the southern region of Ceará, based on the collection of 12 specimens, made with the use of appropriate tools with a thickness of 0.5 cm, the fishes were captured on the Carás River and the São José River, effluents of the Salgado River. With larger sizes and weights, the fishes collected in São José River seem to have adapted to the pollution, since the river receives sanitary sewage from the surrounding neighborhoods and in the dry season is its only source of water. The Carás River does not have sanitary sewage, but its banks have been deforested with several silted places. By demonstrating an ease of adjusting better to a polluted environment and with low oxygen content, the species characterizes an invasive profile.Keywords: Biodiversity; Ichthyofauna; Semi-arid; Tamoatá.O presente trabalho teve como objetivo registrar a ocorrência do H. littorale na bacia do rio Salgado na região Sul do Ceará, município de Juazeiro do Norte, baseado na coleta de 12 espécimes, feita com a utilização de tarrafas com malha de espessura 0,5 cm, foram capturados no rio Carás e no riacho São José, afluentes do rio Salgado. Com tamanhos e pesos maiores, os peixes coletados no riacho São José, parecem ter se adaptado à poluição, visto que o riacho recebe esgotos sanitários dos bairros circunvizinhos e no período de estiagem é sua única fonte de água. Já o rio Carás não apresenta esgotos sanitários, porem tem suas margens desmatadas com vários locais assoreados. Por demostrar uma facilidade de se ajustar melhor a um ambiente poluído e com pouco teor de oxigênio, a espécie caracteriza um perfil de invasora.Palavras-chave: Biodiversidade, Ictiofauna, Semiárido, Tamoatá

New Cretaceous (Aptian/Albian) boxer shrimp (Crustacea, Decapoda, Stenopodidea) from the Araripe Sedimentary Basin, NE, Brazil.

Stenopodidean shrimps are mostly cryptic in their habitats and are typically related with coral rubble or dead coral heads, rocks and crevices, and in association with other marine invertebrate such as sponges, crinoids and corals. Here, we describe a new stenopodidean shrimp, Dubiostenopus parvus n. gen. n. sp., from the Romualdo Formation (Aptian/Albian), Araripe Sedimentary Basin. The specimen studied here was collected in the municipality of Trindade, Pernambuco State, Brazil. The specimen is the imprint of a small shrimp approximately 10 mm in length, with a robust cephalothorax, a well-developed cheliped in the third pereiopod, and a second pleura not overlapping the first. This is the first stenopodidean shrimp described from the Romualdo Formation and the first described from South America. Comparisons with other Brazilian shrimp-like fossils are made, as well as comparisons with all other fossil stenopodideans
