Crotonrizzinii Farias & Riina, sp. nov. is a new species from Serra dos Órgãos National Park in the Atlantic Rain Forest domain (Rio de Janeiro state, Brazil). It is known from the municipalities of Guapimirim, Teresópolis and Petrópolis, where it grows in montane ombrophilous dense forest, between 500 and 1500 m elevation. This arborescent species belongs to CrotonsectionCyclostigma Griseb., a Neotropical lineage distributed in forest habitats from Mexico to northern Argentina. It is mainly characterised by its laciniate-glandular stipules, bracts with two inconspicuous glands (colleters) at the base and campanulate pistillate flowers with sepals covering the ovary. We describe and illustrate the new species, and compare it with close relatives occurring in the Atlantic Rain Forest. We also provide a distribution map, habitat information and suggestions for the assessment of its conservation status.

A study of chironomids (Diptera, Chironomidae) occurring in phytotelmata of Bromeliaceae was carried out in a fragment of the Atlantic Rain Forest in an area of the city of Magé, Pau Grande, one of the metropolitan areas of Rio de Janeiro City, during a period of 13 months between September 2006 and September 2007. Eight samplings were performed at intervals of 1 ½ months and the content of the phytotelmata of the bromeliad species Neoregelia concentrica (Vellozo) L.B. Smith, 1934 and Aechmea nudicaulis (Linnaeus) Grisebach, 1864, were examined. A taxonomical inventory and evaluation of the numerical abundance of Chironomidae larvae were performed in 50 specimens of the bromeliads, being 13 individuals of N. concentrica and 37 of A. nudicaulis. Three taxa of Chironomidae belonging to three distinct subfamilies were recorded: Polypedilum sp., Orthocladiinae genus A and Monopelopia sp. A total of 293 individuals of Chironomidae, were recorded, being 9 Polypedilum sp., 233 Orthocladiinae genus A, and 51 Monopelopia sp., the latter representing the first record of Monopelopia in phytotelmata in Rio de Janeiro State. Considering all samples, a mean density of 3.32 ± 2.62 chironomid larvae per phytotelmata was recorded. There was a positive relationship between the chironomid abundance and both precipitation and the volume of water in the phytotelmata. Apparently there is no preference by the chironomids regarding the colonistion of the bromeliad species.

O objetivo foi analisar a fauna de grilídeos, sua relação com diferentes composições vegetais, o nível de serapilheira e os efeitos da sazonalidade. Foram realizadas quatro coletas, nas quatro estações do ano, entre abril de 2008 e março de 2009. Foram coletados 503 grilídeos com armadilhas de solo, em oito pontos de coleta. Os insetos coletados foram identificados os seguintes gêneros Anurogryllus, Anurogryllus, Argizala, Hygronemobius, Nemobius, Odontogryllus e Pteronemobius. Os grilídeos não possuem afinidade com solos descampados, diminuindo consideravelmente no local mais impactado. O nível de serapilheira não interferiu na abundância e as mudanças sazonais mostraram importância na variação populacional, entretanto, a diversidade e dominância mostraram-se fiéis às alterações ambientais mesmo em menores valores de abundância. Esses resultados mostram que os grilídeos podem ser indicadores ambientais, pois respondem às modificações do meio. Composition and Diversity of the Crickets Fauna (Orthoptera: Grylloidea) in a Fragment of Atlantic Rain Forest in the Rio de Janeiro State Abstract. This study aimed to analyze the fauna of cricket, its relation with different plant compositions, litter level and seasonality effects. Four collections were performed, in four season of the year, between April 2008 and March 2009. It was collected 503 crickets using soil traps, in eight sampling points. The insects collected were identified as the genera Anurogryllus, Argizala, Hygronemobius, Nemobius, Odontogryllus e Pteronemobius. The crickets have no affinity with uncovered soil, decreasing significantly in more impacted places. The litter level did not affect the abundance and the seasonal changes shown importance in the population variation, however, diversity and dominance showed fidelity to environmental changes even in lower abundance. These results show that crickets may be environmental indicators due to the answers the changes in environment.

Seven species of the genus Chiromyza Wiedemann are recorded in Brazil: C. brevicornis (Lindner, 1949), C. enderleini (Lindner, 1949), C. leptiformis (Macquart, 1838), C. ochracea Wiedemann, 1820, C. stylicornis (Enderlein, 1921), C. viridis Bezzi, 1922 and C. vittata Wiedemann, 1820. Herein I describe a new species, Chiromyza raccai sp. nov., based on 88 specimens (41 males, 47 females) from the Atlantic Rain Forest mountains of State of Rio de Janeiro, Brazil, in the city of Miguel Pereira. The new species is distinguished from the related species C. ochracea and C. vittata by the structure of male terminalia. Chiromyza raccai sp. nov. has the distal region of the phallus rounded with two conspicuous apical setae, C. ochracea has the distal surface of the phallus wide and flatness, and C. vittata has the distal surface of the phallus rounded with outer margin rugose.

Studies have identified the central region of the Brazilian Atlantic Forest as an area of high biodiversity and endemism. Strong anthropogenic pressure has made protected areas in Rio de Janeiro State important sites for biodiversity conservation as they contain many areas of extreme biological importance. We sought to document and qualitatively describe the arboreal species composition of the Tinguá Biological Reserve by examining the collection data of the herbaria at the Instituto de Pesquisas Jardim Botânico do Rio de Janeiro (RB) and the Universidade Federal Rural do Rio de Janeiro (RBR). The survey identified 563 species belonging to 249 genera and 77 families, including 13 new occurrences for Rio de Janeiro State, 34 endemic species for the state, 17 vulnerable species, 15 endangered species, and one critically endangered species. Our results demonstrate the importance of this environmental protection area to the conservation of many plant populations and identified the region as harboring high tree diversity—thus reinforcing its role as an important forest remnant in a fragmented landscape within a threatened biome.

The Atlantic Rain forest, which is considered the second largest pluvial forest in the American continent, has had an estimated 93% of its original area destroyed. Although studies concerning the herpetofaunal diversity in this biome have been intensified in the past years, its diversity is still underestimated. The Nucleo Experimental de Iguaba Grande (NEIG) is included in an Environmental Protection Area (APA de Sapeatiba) in the Iguaba Grande municipality, Rio de Janeiro state, Brazil (22º 51' S and 42º 10' W). The goal of this study was to conduct an inventory of the reptile and amphibian species that occur in this area between July 2008 and December 2009. We recorded 19 species of amphibians (18 anurans and one caecilian) and 15 species of reptiles (three lizards, 11 snakes and one amphisbaenian). Leptodactylus latrans and L. mystacinus had the highest capture rates among amphibians captured, and among reptiles, Ameiva ameiva, Hemidactylus mabouia and Mabuya agilis had the highest capture rates. Rarefaction curves for both amphibians and reptiles did not reach the asymptote, indicating that the species richness in the NEIG is still underestimated.

A new species of Dendrophryniscus is described from the Atlantic Rain Forest, in the Serra dos Órgãos, State of Rio de Janeiro, Brazil, at 1050 m a.s.l. The description was based on three female specimens, with a mean snout-vent length of 23.0 mm. The new species, Dendrophryniscus organensis, differs from the eight other known species in having a characteristic dorsal color pattern, with the tips of the fingers and toes, the snout, and the sub-rostral crest reddish-orange, rostral angle accentuated, end of the snout triangular in dorsal view, and the relation of tibia and snout-vent length equals to 0.4. The large size of the oocytes suggest that the new species reproduces in bromeliads, which places the new species in the D. brevipollicatus group together with D. berthalutzae, D. carvalhoi, D. krausae, and D. stawiarskyi.
