A new legume species from Southeastern Brazil, Poecilanthe fluminensis, is described and illustrated. It is readily distinguished from the remaining species of the genus by a combination of exclusively unifoliolate leaves with very short petioles (5–9 mm long), red calyx, and strongly dimorphic anthers (short anthers less than ¾ of the length of the longer ones). The new species, P. fluminensis, appears to be endemic to Rio de Janeiro State, Southeastern Brazil.

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.

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.

ABSTRACT A new species of loricariid catfish is described from the rio Perequê-Açú and surrounding basins, Parati, Rio de Janeiro State. The new species has the accessory process of ceratobranchial 1 more slender than the main body of the ceratobranchial, and a very large sesamoid ossification, markedly greater in size than the interhyal. Additionally, the new species presents a distinct dorsal color pattern consisting of a conspicuous horseshoe shaped light blotch with a central dark area posterior to the supraoccipital.

Shape And Size

Anaulacomera currently contains 147 valid species, of those 50 are recorded from Brazil. The genus is further divided into six subgenera, which can be distinguished on characteristics of the male terminalia. A new Brazilian species is presently proposed, Anaulacomera (Anallomes) curvata sp. nov., based on three males and one female collected at Parque Nacional de Itatiaia, Itatiaia, Rio de Janeiro State. It can be distinguished from all other species because of the pair of cerciform projections of the tenth male abdominal tergite and a combination of shape and size of the male cerci.

A new species of Multumbo Roewer, 1927 (Gonyleptidae: Hernandariinae), M. dimorphicus sp. nov., is described from Rio de Janeiro state, southeastern Brazil. It presents sexual dimorphism in leg IV, contrasting remarkably with the type species of the hitherto monotypic genus Multumbo and the closest genera (Piassagera Roewer, 1928 and Pseudotrogulus Roewer, 1932), which were all thought to have lost this dimorphism. The presence of sexual dimorphism in M. dimorphicus implies a complex scenario of loss or reversal of this character. New records are given of type species of genus, Multumbo terrenus Roewer, 1913, for which a lectotype is designated. New diagnoses are provided for Hernandariinae and Multumbo. Multumbo and Piassagera are transferred from the Gonyleptinae to the Hernandariinae.Uma nova espécie de Multumbo Roewer, 1927, M. dimorphicus sp. nov., é descrita do estado do Rio de Janeiro. Ela apresenta dimorfismo sexual na perna IV, condição em notável contraste com a espécie-tipo do até então gênero monotípico Multumbo e com os gêneros mais relacionados, Piassagera Roewer, 1928 e Pseudotrogulus Roewer, 1932, nos quais esse dimorfismo era considerado como perdido. A presença de dimorfismo sexual em M. dimorphicus sugere um complexo cenário de perda ou reversão desse dimorfismo. Também foram incluídos novos registros da espécie-tipo do gênero, Multumbo terrenus Roewer, 1913, e um lectótipo é designado. Novas diagnoses para Hernandariinae and Multumbo são apresentadas. Multumbo e Piassagera são aqui transferidos de Gonyleptinae para Hernandariinae.

Soaresia forficula sp. nov. is described from the Mantiqueira Mountain Range, Minas Gerais State, southeastern Brazil. The genus Soaresia H. Soares, 1945 previously included only Soaresia uncina H. Soares, 1945, hitherto recorded only from the type locality, Penedo, Rio de Janeiro State, in the same mountain range. A second record of S. uncina is given from a nearby locality, Serrinha do Alambari. The combined distribution of the species of Soaresia is restricted to elevations between 700 and 1300 m, in the Tropical & Subtropical Moist Broadleaf Forests biome. An emended diagnosis of the genus is given and complements are given to the description of S. uncina, including the first illustrations and description of the male genitalia.

Phylloicus Müller 1880 is an endemic Neotropical genus of Calamoceratidae characterized by adults that have diurnal to crepuscular habits. Currently, the genus contains 57 species, with 23 of these species recorded from Brazil. Herein, a new species of Phylloicus is described and illustrated based on specimens collected in Malaise traps from Southeast Region, Brazil. The new species can be characterized by the unusual lateral membranous lobes of abdominal segments IV–VII, metathoracic tibiae with brushes of setae and distal emargination, and the wide and long coremata on abdominal pleura VII. Otherwise, the genital structure is similar to that of Phylloicus monneorum Dumas & Nessimian 2010, being distinguished by the subtrapezoidal tergum X, the globose harpago of the inferior appendages, and the moustache-shaped phallotremal sclerite.
