Remarks.

First species record for the Brazilian Amazon Coast. The features that confirm these specimens as Exogone (Exogone) breviantennata Hartmann-Schröder, 1959 are median and lateral antennae of similar size, compound spinigers and falcigers with bidentate blades (subdistal tooth larger than distal tooth) and falcigers in the anterior body with 3-4 relatively thick spines. This species is found worldwide in several habitats such as in seagrass in the intertidal zone, rocky shores, algae asSEMblages, soft bottoms ( San Martín and Bone 2001, Paresque et al. 2014), and others. The type material of E. (E.) breviantennata is from a mangrove ( Hartmann-Schröder 1959) as in the present study. However, this species has been recorded in several environments and it presents a circumtropical distribution ( Núñez et al. 1992).
