溪蟹科

According to either sequence data sets or gene arrangement features at both gene junctions, Brachyuran crabs were monophyletic and divergent between Heterotremata and Thoracotremata. Potamoidea represented by S.

本文基于基因序列和排列数据的系统发生分析都支持短尾类是一单系群；异孔类和胸孔类互为姐妹群；以长江华溪蟹为代表的溪蟹总科与扇蟹总科、梭子蟹总科有较近的亲缘关系。

The phylogenetic analysis of these two nonmarine crabs together with intertidal, supratidal and swimming crabs based on portions of mitochondrial 16S rDNA sequences suggested that Grapsioidea, Ocypodoidea, Potamoidea and Portunoidea arose from a common marine ancestor, and the estimated divergence time are similar.

基于线粒体16S rDNA部分序列，对这2个类型的非海洋蟹类与潮间带蟹类、海洋蟹类之间的系统发生分析提示，方蟹总科、沙蟹总科、溪蟹总科和梭子蟹总科的蟹类起源于一个共同的海洋蟹类祖先，它们彼此之间的歧异时间基本一致。

Results We discovered and confirmed that there were 17 different species of 1st intermediate host of in Paragonimus Jiangxi, covering 2 families and 3 genera, and 23 different species of 2nd intermediate host, covering 1 order, 1 family and 3 genera, 15 of which were reported to be new species by the authors. Furthermore, a new genus of Jiangxi Huananpotamon was built up, based on the assumption that Wuyi mountain range is the developing centre of Huananpotamon , and tend to spread out towards Jiulian mountain of Nanling mountain range adjacent to Guangdong Province and Luoxiao mountain range next to Hunan Province. In addition, Jiangxi Province freshwater crab order was created at the end of research, as well as a complete classification and retrieval table of its order and genus. The authors also proved that the advantageous stocks of freshwater crabs carrying encysted metacercaria of Jiangxi Paragonimus westermani were Sinopotamon fukiense and S.wanzaiense .

结果 江西卫氏并殖吸虫第一中间宿主淡水螺种或媒介共计17种，隶属2科3属；第二中间宿主淡水溪蟹种或媒介为23种，隶属1总科1科3属，其中15种为作者等研究发现报告的新种；建立了江西并殖吸虫媒介新属——华南溪蟹属，认为武夷山脉是华南溪蟹属类群的分化中心，并有向与广东毗邻的南岭山脉的九连山和与湖南接壤的罗霄山脉扩展的趋势；建立了江西省淡水蟹类总科及科与属的分类检索表；证实携带江西卫氏并殖吸虫囊蚴的淡水溪蟹优势种群为福建华溪蟹、万载华溪蟹
