The parasitoid wasps Belytinae (Hymenoptera: Diaprioidea: Diapriidae) recorded thus far in the Atlantic Dense Ombrophilous Forest are reviewed at the supra specific level. The knowledge about the diversity of Belytinae in the Atlantic Forest is relatively poor, although these parasitoids may play a key role in the natural regulation of populations of the Mycetophilidae and Sciaridae (Diptera). The material used in this study comes mostly from standardized collections in 18 regularly spaced sites, from Paraíba to Santa Catarina Brazilian states, between 2000 and 2002, by the project “Richness and diversity of Hymenoptera and Isoptera along a latitudinal gradient in the Atlantic Forest – the eastern Brazilian rain forest” (Biota/SP – FAPESP). At each location ten Malaise traps and a hundred Moericke traps were installed, both along two parallel transects spaced 100 m from each other. Further, a similar effort for the sweeping of vegetation was applied at each locality, being each sweeping sample the result of 5 minutes of sweeping. Traps, and sweeping of vegetation in the summed localities yielded a total of 1,241 Belytinae specimens, of which we recognize 115 morphospecies in eight genera (Aclista, Belyta, Cinetus, Odontopsilus, Scorpioteleia, Lyteba, Tropidopsilus and Camptopsilus). A further belytine genus (Miota), recorded in similar environment, was found at the collection of the Federal University of Espírito Santo and added to the list, totalling nine here keyed genera; for each genus we include a diagnosis, comments and a discussion on its records, distribution and biology; we also provide twenty-two plates with 102 figures (93 photographs and 9 maps).

Understanding variation of species richness along latitudinal gradients, with more species toward the tropics, represents a challenge for ecologists. Species richness also varies according to the available area, with more species in larger regions, with area and latitude posited as major drivers of richness variations. However, species richness does not fully capture the evolutionary history behind those patterns. Phylogenetic diversity can provide insights on the role of time and evolutionary drivers of environmental gradients. We analyzed here the latitudinal gradient of endemic snakes from the Atlantic Forest of South America, a megadiverse and highly threatened portion of the Neotropics. We assessed the effect of area and average clade age on species richness and phylogenetic diversity, testing whether species richness and phylogenetic diversity increase with area availability and in lower latitudes. We found that area can predict species richness, but not phylogenetic diversity. Brazilian southeastern mountain ranges include larger patches of Atlantic Forest and the highest richness levels, but generally harboring snakes from relatively recent clades (neoendemics). There is a negative relationship between species richness and average clade age along the latitudinal gradient, with older clades found mainly in northern portions, increasing phylogenetic diversity at lower latitudes. Different dimensions of diversity, species richness and phylogenetic diversity, are thus affected in different ways by area and time for speciation in the Atlantic Forest, and this may be a trend in highly diverse tropical regions.

A New Species

Abstract—A new species of Eugenia from the Atlantic forest of Brazil is described and illustrated. Eugenia flavicarpa is restricted to the Floresta de Tabuleiro (lowland forests) of Espírito Santo state and is nested in Eugenia subg. Pseudeugenia. Considering all other species of the subgenus that occur in forest vegetation types of the Atlantic forest phytogeographic domain, Eugenia flavicarpa can be distinguished mainly by the combination of smooth leaves with indumentum on both surfaces, with two marginal veins, usually ramiflorous inflorescences, pedicels 4.5‐9.7 mm long, flower buds 3.5‐4 mm in diameter, and by the calyx lobes that are 2‐3 mm long with rounded to obtuse apices. Morphological analyses were performed to explore the significance of quantitative diagnostic features between the new species and the closely related species, Eugenia farneyi. Notes on the habitat, distribution, phenology, and conservation status of Eugenia flavicarpa are provided, as well as a key for all species of Eugenia subg. Pseudeugenia from forest vegetation of the Atlantic forest phytogeographic domain.
