Based on a cladistic biogeographic analysis of 6 species-level phylogenies of harvestman taxa, wesearched for congruence in the historical relationships of 12 areas of endemism of the BrazilianAtlantic Rain Forest. We constructed general area cladograms using Primary Brooks ParsimonyAnaJysis （BPA）, BPA of nodes, and paralogy-free subtree analysis. These analyses resulted in 6general area cladograms, that allow to infer a general pattern of the relationships among areas ofendemism from the Brazilian Atlantic Rain Forest. Northern areas resulted related basally showingmain disjunctions at the Doce River Valley and Todos os Santos Bay/S^o Francisco River Valley.The remaining areas of endemism were included in a southern and a southeastern block, sepa-rated by the Ribeira do Iguape Valley. Incongruence Length Differences tests showed no significantincongruence among the resulting cladograms and other matrix partitions. We concluded that tec-tonism and ancient marine transgressions were the probable processes responsible for the maindisjunctions, whereas Neogene refugia seem to have caused the more recent disjunctions. Thegeneral pattern and redundancy in area relationships suggest a model of main reiterative barriersin diversification at multiple times for the evolution of the Atlantic Rain Forest. The renewal of cla-distic biogeography and the search for common biogeographic patterns are discussed.

Intraspecific phylogeography of Carchesium polypinum (Peritrichia, Ciliophora) from China, inferred from 18S-ITS1-5.8S ribosomal DNA

Based on the variation of site 34, 46, 241, 305 and 322 in the 18S-ITS1 rDNA sequence, 19 Carchesium polypinum populations collected from eight provinces of China were separated into northern and southern population along the delineation between the Yangtze River and the Pearl River. This geographic distribution pattern of Carchesium polypinum maybe results from two factors: the vicariance resulting from the formation of the delineation between the Pearl River and the Yangtze River accompanied with the uplift of Qinghai-Xizang Plateau, and the different dispersal paths of C. polypinum affected by the climate.
