RESUMO:

Microcrustaceans of the Copepoda subclass are considered the most abundant metazoans of marine zooplankton. These small aquatic animals play an important role in the marine ecosystem, in addition, they have great economic importance. The order Siphonostomatoida Thorell, 1859 is composed of organisms that live as parasites or in association with other animals. Currently, 2.235 species of siphonostomatoids are known to science, however, 79% of this diversity corresponds to fish parasites, probably due to the damage caused to aquaculture. Thus, only 21% of known species live in association with marine invertebrates. Among the Siphonostomatoida families, Asterocheridae is the largest associated with marine invertebrates, with about 289 species in 64 genera, probably a consequence of being used as a deposit of species that do not belong to the other families. This work two new species are described for the Asterocheridae family, associated with the sponge Callyspongia. Asterocheres sp. nov. differs from the other congeners for presenting the following combined characteristics: body shape, antenna exopod ornamentation, maxilliped formula, absence of the aesthetasc-like element in the maxilla, and presence of two setae on leg 5. The second new species, Phyllocheres sp nov., presents as exclusive characteristic: mandibular palp with 1-segmented and maxilliped with 4 segments. Therefore, we contribute to the increase in knowledge of Brazilian diversity, with the description of two new species: Asterocheres sp. nov., and Phyllocheres sp. nov. In addition, the first record of Phyllocheres for the Atlantic Ocean.
