General Aspects

Two new species of the genus Cephalophoxoides Gurjanova, 1977 are described. The material examined was collected during the Mini Biological Trawl (MBT) project, off Brazil’s southeastern coast on the states of Rio de Janeiro and São Paulo, at depths ranging from 34 to 75 meters. Cephalophoxoides fortisetus sp. nov. resembles C. homilis (Barnard, 1960) in some general aspects of mandible, propodus of gnathopods 1–2, basis of pereopod 5 and rami of uropod 1. However, it can be distinguished by the latter species mainly by distinct characters on the maxilliped, gnathopod 1, uropod 2 and uropod 3. Also, the new species presents 1 short and 2 long stout setae on the lobes of telson as a notable character. Cephalophoxoides obtusimanus sp. nov. can be distinguished from its congeners by presenting gnathopod 1 with an obtuse and weakly chelate palm as an exclusive character of the genus. An identification key for all species of Cephalophoxoides of the world is provided.

Two New Species

Two new species of Myrcia from the Atlantic rainforest in southeastern Brazil, Myrcia congestiflora and Myrcia longipaniculata are here described and illustrated. Myrcia congestiflora occurs in São Paulo and Rio de Janeiro states and is similar to Myrcia cerqueiria, differing by having densely sericeous indumentum (versus sparse and shorter trichomes), larger flowers and flower buds (flower buds with 3–4 mm versus 1.1 mm long) and by acute or obtuse calyx lobes rather than rounded. Myrcia longipaniculata is known for one collection from the boundary of São Paulo and Rio de Janeiro differing from Myrcia spectabilis mainly by the longer inflorescence size (29 cm versus 3.5–21.5 cm long.) as well as for presenting a strong reddish or ferruginous indumentum (versus brown to yellowish).

Males And Females

The genus Aguana Melichar, 1926 previously included only two species from the Atlantic Forest of Southeastern Brazil. Here we provide a revised diagnosis for the genus and describe two new Brazilian species and the female of A. imbricata (Signoret, 1854). The new taxa are A. picinguaba sp. nov. (states of Rio de Janeiro, São Paulo, and Santa Catarina) and A. spitzi sp. nov. (State of São Paulo). Aguana species are very similar to one another externally and can be distinguished mainly by features of the male terminalia (especially of the aedeagus) and female sternite VII. A key to males and females of the genus is added (except the female of A. russata Young, 1977).

Two new species of Ctenitis (Dryopteridaceae) from South America are described and illustrated: Ctenitis christensenii is endemic to southeastern Brazil and C. glandulosa occurs from southeastern to northeastern Brazil and in Guyana. An identification key and notes about the distribution, habitat and taxonomy of the new species, C. falciculata and allies are provided. Moreover, seven lectotypifications and two new synonyms are proposed.

A New Species

Miconia goldenbergiana, a new species from the Atlantic Forest in southeastern Brazil, is described and illustrated. The new species have been extensively collected since the end of the XIX century but have been confused with M. budlejoides and M. formosa, species that also have discolorous and suprabasal leaves and glomerulate inflorescences. From the first species, it can be distinguished by papyraceous leaves with the abaxial surface covered by lepidote trichomes. From the second species, it can be distinguished also by the texture of leaves, and by its narrower size, crenulate to serrulate margins and acute base, besides the smaller size of the flowers. The new species is known from the states of Espírito Santo, Rio de Janeiro and eastern São Paulo, and is in danger of extinction.

Two new species of Paratubana Young, 1977 are described and illustrated from Rio de Janeiro state, southeastern Brazil, based on specimens collected in alpine fields (above 1,800 m) of the Serra dos Órgãos mountain range. Paratubana auromarginata sp. nov. (Pico da Caledônia) can be recognized by the paraphyses with the apex bifurcate, forming an outer subquadrate projection and inner spiniform process, whereas in P. takiyae sp. nov. (Parque Nacional da Serra dos Órgãos) the paraphyses have a pair of strong spiniform processes directed dorsally and crossing each other. The two new species are apparently closely related to each other and both use Eryngium L. (Apiaceae) as host plants. A key to males of the ten known species of the genus is added, as well as two maps of their known distribution.

Xestospongia Muta

Petrosiidae (Haplosclerida, Demospongiae) is characterized by the hard and friable consistency, and an isotropic reticulated skeleton of oxeas/ strongyles. The Brazilian coast and oceanic islands harbor three out of four known genera of Petrosiidae: Neopetrosia de Laubenfels, 1949; Petrosia (Petrosia) Vosmaer, 1885 and Xestospongia de Laubenfels, 1932. A taxonomic survey of samples from several expeditions housed at the Porifera Collection of Museu Nacional, Universidade Federal do Rio de Janeiro, with additional comparative materials obtained from the Museu de Ciências Naturais, Fundação Zoobotânica do Rio Grande do Sul, and Universidade Federal de Pernambuco enabled the description of two new species: P. (P.) revizee sp. nov. and X. dorigo sp. nov. We also recorded a range extention for Neopetrosia proxima and Xestospongia muta, and Xestospongia grayi was synonymized with X. muta. Other species reported from the country are diagnosed, and an identification key for Petrosiidae from Brazil is provided.

(Bahia State, Brazil) and L. viridis sp. nov. (Rio de Janeiro, São Paulo, and Paraná States, Brazil). Species belonging to the new genus can be distinguished from other genera of Cicadellini based on the following characters: (1) pronotum narrower than head with lateral margin parallel; (2) male pygofer without processes; (3) subgenital plate longer than pygofer with many microsetae distributed across its surface; (4) aedeagus with an unpaired apical process, and (5) paraphyses absent.
