03BE87E6DA75287283565CD83355ADDF.taxon	discussion	Remarks: Metharpinia dentiurosoma was described with material from Buenos Aires (Argentina) and this is the first record of the species for Brazilian waters. Due to characteristics of antennae, mandibles, gnathopods and uropods, this species seems to be morphologically close to Mi. uroserratus described for Sepetiba Bay, Rio de Janeiro state, Brazil (22 ° 58 ′ S, 44 ° 02 ′ W). However, it can be distinguished by the latter by presenting: head with a visible acute dorsolateral projection, rostrum slightly exceeding apex of first article of antenna 1; epimeral plate 3 posteroventral corner strongly produced into a large tooth and facial margin with an oblique row of stout setae. Geographic distribution: Argentina: Argentine Sea; Brazil (this report): coast of the states of Rio de Janeiro, São Paulo and Santa Catarina. Bathymetric range: 14 ‑ 72 m depth.	en	Andrade, Luiz F., Senna, André R.

03BE87E6DA7C287483FE5F183347AA1F.taxon	discussion	Remarks: Metharpinia grandirama was described with material from Buenos Aires (Argentina) and this is the first record of the species for Brazilian waters. Due to characteristics of antennae, gnathopods and especially the shape of uropods 1 ‑ 2, this species seems to be morphologically very close to Mi. breviramus, described for Arraial do Cabo, Rio de Janeiro state, Brazil (23 ° 03 ′ S, 42 ° 02 ′ W), with both presenting rami of uropods 1 ‑ 2 much shorter than the other species of their respective genus. However, M. grandirama can be distinguished by the latter by subtle characteristics like: head with a visible dorsolateral projection; pereopod 7, basis not so expanded posteriorly; setal distribution on epimeral plates 1 ‑ 3; and number of stout setae on uropods 1 ‑ 2. Even if morphological variations are reported for different individuals of both species, due to the strong similarities on their uropods, a new analysis of the type material used for the original descriptions is necessary in order to confirm if both species are valid or if they should be synonymized. Geographic distribution: Argentina: Argentine Sea; Brazil: coast of the states of Rio de Janeiro and São Paulo. Bathymetric range: 9 ‑ 72 m depth.	en	Andrade, Luiz F., Senna, André R.
