This is the first report of the genus Stibarobdella for Northeastern Brazil. Two specimens isolated from the host were identified in the invertebrate collection at LIMCe (Laboratório de Invertebrados Marinhos do Ceará). The specimens were collected off Paracuru town, a coastal location in Ceará State, Northeastern Brazil (3°25′31″ S, 39°1′29″ W), at a depth of 40 m on July 13th, 1977. The host elasmobranch from which the specimens were retrieved Marine leeches, especially those with parasitic habits, are important components of the ecosystem (Siddal and Burreson 1998; Utevsky and Trontelj 2004; Wunderlich et al. 2011). Approximately twenty species of marine leeches, all of which of the family Piscicolidae, feed on blood from sharks and rays and are known to be vectors of elasmobranch hematozoa (Caira and Healy 2004; Utevsky and Trontelj 2004). Most piscicolids are circumglobal in tropical and subtropical oceans (Utevsky and Tronjelj 2004). Marine leeches feeding on elasmobranchs have previously been reported for

This paper describes a species of the genus Cyphocaris Boeck, 1871, the first record of the family Cyphocarididae Lowry & Stoddart, 1997 from Brazil. Two specimens, both females, were found in the stomach contents of a tuna caught in the Saint Peter and Saint Paul Archipelago. The new species is characterized by coxae 4 and 5 both large, coxa 4 partially overlapping coxae 2-3; coxa of pereopod 5 with ventral laminar projection and well-developed anteroventral lobe, broadly rounded and apically folded backwards, basis with anterior margin broadly rounded and posterior margin with large subacute naked projection (or spur); uropod 3, outer ramus paddle-shaped; and telson elongate and deeply cleft, with a nail.

A new Late Cretaceous species of Petalobrissus, Petalobrissus lehugueurae sp. nov., is described from the Jandaíra Formation, Potiguar Basin, state of Rio Grande do Norte. To date, this genus comprises a total of 20 species, only two of which, Petalobrissus setifensis and Petalobrissus cubensis have so far been recorded from the Jandaíra Formation. Petalobrissus lehugeurae sp. nov. is distinguished from its congeners in that gonopores occupy only a small portion of the genital plates, in having a slit-like periproct and a unique abrupt depression of the test that forms a pronounced keel below the periproct. In addition, an identification key to species of Petalobrissus is presented.

Two new species of Quadrimaera are described from Brazil. Quadrimaera yemanjae sp. nov. shows article 2 of mandibular palp longer than the others, coxa 1 with anteroventral corner rounded and 8 concavities on gnathopod 2 propodus palm. Quadrimaera miramirandella sp. nov. shows coxa 1 with anteroventral corner rounded and produced, gnathopod 1 with carpus longer than propodus with plumose setae, telson lobes equal in length. New distributional records are reported for Q. cristianae, Q. rocasensis and Q. pieteri. The female of Quadrimaera rocasensis is described for the first time. Quadrimaera pieteri is reviewed and established in Brazil. A taxonomic key of the genus is provided.
