| Objective:Systematic analyze the freshwater crab species in Wuyi Mountains area, summarize the diversity and breeding ground of freshwater crab species in Wuyi Mountains area, discuss their zoogeographical significance.Methods:Based on review and comparison the freshwater crab type specimens (Holotype) in the Wuyi Mountains and historical reference materials, field-collect samples from the 99 locations throughout Wuyi Mountains, using morphological classification and sorting.Results:.The ongoing study found that the geographical distribution of Wuyi Mountains has 5 genera and 33 species of freshwater crabs, and the species of freshwater crab accounts for 11.7%(33/282) of total in China; of which 87.9%(29/33) of the freshwater crab, were found only distributing in the mountains of east or west sides, probably because of higher altitude Wuyi mountains by blocking effects which confirms distribution pattern of geographic distribution that the freshwater crabs mostly mountains (water),and implies that the mountains have disctinct impact on ranges of freshwater aquatic creatures-fresh water crab in reproductive isolation.Study found that 4 species fresh water crabs can be distributed in the Wuyi mountains on both sides, and one of the reasons may be, in the geographical distribution of certain species freshwater crab,as the existence of low-altitude mountain access, and both sides of the river here, homogeneous connectivity objectively created a freshwater crab spread along the river natural conditions.Plus, field researchs and analysis of the past reference show that Wuyi Mountains at different altitudes and rugged terrain, topography and vegetation, climate, temperature differences and changes in freshwater crab species also have a significant effect on the breeding of reproduction, so that different species of freshwater crab prefer selecting presence of specific micro-ecological nature geography environment.
