High Diversity

Three new species of the six-eyed haplogyne and ecribellate spiders from the genus Ochyrocera Simon, 1891 are illustrated and described based on males and females from southeastern Brazil: Ochyrocera tinocoi new species (Sooretama, Espírito Santo state), Ochyrocera garayae new species (Linhares and Sooretama, Espírito Santo state) and Ochyrocera itatinga new species (Rio de Janeiro city, Rio de Janeiro state). The new species expand the distribution range of Ochyrocera in Brazil and increase to 50 the total number of species described, from which hitherto 33 species occur in South America, acknowledging the high diversity of the genus for the region.

Hemipsilichthys nimius, new species, is described from the upper Perequê-Açu River in Parati, in the southern coast of Rio de Janeiro State, southeastern Brazil. The new species is distinguished from the remaining 18 Hemipsilichthys species by modally having eight branched rays in the dorsal fin (vs. seven branched rays), by possessing a posteriorly expanded dorsal-fin membrane connecting the last dorsal-fin ray to the dorsum and, except from H. gobio and H. papillatus, by having teeth cusps equal in size (vs. small lateral cusp or unicuspid teeth in both dentary and premaxilla). From H. gobio and H. papillatus it is further distinguished by the larger orbital diameter and by its V-shaped dorsal-fin spinelet. Hemipsilichthys nimius shares with H. gobio and H. papillatus several characters that might be indicative of close relationships. These putative phylogenetic relationships are discussed.

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.

Unknown Male

Two new species of Dilobopterus Signoret, 1850 are described from the Atlantic Rainforest of Rio de Janeiro State, Southeastern Brazil, based on specimens collected in Angra dos Reis (D. nelsoni sp. nov.) and Itatiaia (D. sakakibara sp. nov.). Holotypes are deposited in Museu Nacional, Universidade Federal do Rio de Janeiro. These are the first species of the genus described after the publication in 1977 of the last comprehensive monograph on the New World Cicadellini. We also describe the previously unknown male of D. segmentalis (Signoret, 1853) based on specimens from the Atlantic Rainforest of Espírito Santo State, Southeastern Brazil (municipality of Santa Teresa). We propose a group of species within Dilobopterus (trinotatus group) based on features of the paraphyses of D. trinotatus (Signoret, 1853), D. segmentalis, and D. sakakibara sp. nov..

Eremanthus praetermissus is endemic to Serra do Mar, in the northeastern part of São Paulo state and the southern part of Rio de Janeiro state; it is characterized by hemispherical, brown syncephalia, heads connate for 1/3 to 2/5 of their length, with 3–4 florets per head and brown phyllaries with purple apices. Eremanthus ovatifolius is endemic to campos rupestres of Pico da Aliança, in the eastern part of Minas Gerais state, and is characterized by ovate leaves, hemispherical syncephalia, heads connate for 1/4 to 1/2 of their length and 3–4 florets per head. The affinities of these species are discussed. A key to all species of Eremanthus is provided.

A new species of Pacholenus Schoenherr from southeastern Brazil (Coleoptera, Curculionidae, Molytinae), and new occurrences of species of the genus. Pacholenus monteiroi sp. nov. (type-locality Brazil, Rio de Janeiro state, Carapebus, Parque Nacional da Restinga de Jurubatiba) is described and illustrated. The weevil develops as a stem gall-former in Calyptranthes brasiliensis Spreng (Myrtaceae). The new species is easily distinguished from the other five known of the genus by the presence of a prominent supra-ocular ridge. An updated key for identification for all species of Pacholenus is provided. Three species of Pacholenus are presently recorded for the states of Rio de Janeiro and São Paulo; P. pelliceus and P. monteiroi occur in both states, while P. penicillus is only known from Rio de Janeiro; P. hispidus occurs in São Paulo, being the most widespread species of the genus, ranging from Minas Gerais south to Santa Catarina.
