The class Diplopoda is known for species of low dispersal capacity and limited distribution area, being restricted to mountains, islands, or patches of forests. Members of the Class have agricultural and medical importance. The Chelodesmidae family is the second in richness for Diplopoda, with about 800 described species. In Chelodesmidae, the genus Atlantodesmus Hoffman, 2000 is known for the absence of ventral projections on the sternites of the body rings and for characteristics of the reproductive structure of the males. To date, seven species of the genus are known widely distributed along the Atlantic Forest and Cerrado. Among these species, Atlantodesmus teresa (Hoffman) is endemic to the Atlantic Forest. The present work aims to characterize the species based on an ultrastructure analysis and mapping its distribution in the biome from data gathered in biological collections. As result, 15 adults from the states of Espírito Santo and Minas Gerais were identified, with the main morphology related to the male gonopods. Further studies are still necessary to understand the distribution of the genus and the richness of the family in the biome. [ABSTRACT FROM AUTHOR]

Six new Kielmeyera species (Calophyllaceae) are presented here (K. cataractae, K. colibri, K. doceana, K. inopinata, K. oreophila, and K. stevensii), all from the Atlantic Forest in southeastern Brazil, from the states of Espírito Santo, Minas Gerais, and Rio de Janeiro. Complete descriptions, illustrations, and morphological comparisons with the most similar species for each new species are provided. We also estimated their conservation status according to IUCN criteria. Additionally, an identification key for Kielmeyera species with pollen grains in monads and usually ciliated sepal margins from Atlantic Forest and a comparison table are provided.

Behuria comosa Tavares, Baumgratz & Goldenberg is a new species from Minas Gerais and Espírito Santo, Brazil. It can be recognized by the branch nodes, sinuses of the leaf margins and domatia comose, leaves and inflorescence axes frequently three-whorled, flowers five(–six)-merous, calyx lobes broadly triangular and with the apex laterally flattened, and petals glabrous, thickly apiculate. © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society, 2008, 158, 489–492.
