A New Species

A new species, Isotogastrura praiana sp. nov., is described and illustrated based on the specimens collected from Rio de Janeiro, Southeastern Brazil. The new species is more similar to Mexican Isotogastrura ahuizolti Palacios-Vargas & Thibaud with respect to presence of two pre labral microchaetae and six sensillae on fourth antennal segments. Diagnostic features of new species are absence of sensilla D and presence of sensilla E on fourth antennal segments, distributing dorsal tubercles from second thoracic segment to third abdominal segment and greyish body color.

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

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.

A New Species

A new species of the freshwater amphipod Hyalella Smith, 1874 is described for the plateau of the Itatiaia National Park, located between the states of Minas Gerais and Rio de Janeiro, southeastern Brazil. This is the first Brazilian species of Hyalella found at more than 2,200 meters of altitude. The specimens were found in a small stream, buried under rocks, in the higher area of the Park. The main morphological characteristics that differentiate the new species are the extreme reduction of the size of the uropod 3, absence of apical setae on telson, absence of comb-scales on gnatopods 1 and 2, absence of curved seta on inner ramus of uropod 1 and sternal gills tubular on pereonites 3 to 7. The new species presents similarities with some cave species of the genus, apparently being troglophile and that is the process of adaptation to the hypogean habitat. The importance of creating new protected areas for the conservation of Hyalella in Brazil is discussed.

A new species of Mimosa is described from the Atlantic Rainforest and ecotone with the Cerrado of southeastern Brazil, in the states of Minas Gerais, Rio de Janeiro and São Paulo: M. porrecta L. Jordão, M.P. Morim & Baumgratz (Leguminosae). Related to M. sensitiva, it shares morphological affinities with this species but differs in having porrect-stellate trichomes, a new type of trichome for the genus, on the stems, and the dendritic trichomes in the fruits. The conservation status was assessed, according to IUCN criteria, as Least Concern.

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.

Here we describe a new genus, Cleidella gen. nov., and two new species, C. picea sp. nov. and C. silveirai sp. nov., all from Rio de Janeiro State, Brazil. The new genus is characterized by the interantennal distance subequal to scape length, antenna with 11 antennomeres, IV to X with two long symmetrical branches; mandibles long, projected and not crossed, pointed forward obliquely from head; maxillary palpi 4‑segmented, last segment digitiform; labial palpi 2‑segmented; posterior tentorial pit consisting of a single small fossa; elytron surpassing from the fourth to fifth abdominal segment, 3.3‑3.9× longer than wide; first tarsomere of protarsus with a ventral comb as long as the tarsomere length; wing with radial cell closed and transverse, vein r4 interrupted; aedeagus with paramere symmetrical, apex unevenly round, toothed inward, with short and scarce bristles. We provide a key to Mastinocerinae genera with 11 antennomeres, as well as illustrations for the diagnostic features for this new genus and a key to its species.

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.
