腹足动物

Macro-invertebrate from Annelida, Mollusca and Arthropoda were found in six sections from Baihe to Zhejiang road in the Suzhou River, among which four species were from Oligochaeta, two species from Hirudinea, five species from Gastropoda, two species from Bivalvia and several species from Insecta.

苏州河白鹤至浙江路段6个采样断面大型底栖动物隶属于环节动物门、软体动物门及节肢动物门。其中寡毛纲4种、蛭纲2种、腹足纲5种、双壳纲2种及昆虫纲摇蚊科幼虫与潜蝇蛹。

The study history of cave invertebrate in China is summarized in this paper. We list new species of Chinese troglobiotic invertebrate found over the past twenty years, and two types of cave invertebrate are divided according to the differences of the habitat: terrestrial community and aquatic community. The review also emphasizes the current research on Arachnolida, Diplopoda, Insecta, Crustacea and Castropoda.

本文介绍了我国洞穴无脊椎动物研究的简史，列出了近20多年来我国发现的真洞穴无脊椎动物种类，并根据栖息环境的不同，将洞穴无脊椎动物划分为陆生群落和水生群落；着重介绍了蛛形纲、重足纲、昆虫纲、甲壳纲、腹足纲的研究现状。

Macro-invertebrate from Annelida, Mollusca and Arthropoda were found in six sections from Baihe to Zhejiang road in the Suzhou River, among which four species were from Oligochaeta, two species from Hirudinea, five species from Gastropoda, two species from Bivalvia and several species from Insecta.

苏州河白鹤至浙江路段6个採样断面大型底棲动物隶属於环节动物门、软体动物门及节肢动物门。其中寡毛纲4种、蛭纲2种、腹足纲5种、双壳纲2种及昆虫纲摇蚊科幼虫与潜蝇蛹。

The results of the analysis to complete 18S rDNA and partial 28S rDNA D 6-7 domain sequences of 30 collembolan species supported the monophyly of Poduromorpha and Symphypleona, Entomobryoidea is not a monophyly, familia Neelidae should be separated from Symphypleona. The situation about the superfamilia of Tomoceroidea and the familia Neelidae need further studies. The results of the further analysis to complete 18S rDNA and nearlly completely 28S sequences of 4 Protura, 6Collembola, 5 Diplura, 5 Insecta, 10 Crustacean, using 1 Myriapoda and 1 Chelicerata as outgroups indicated that Protura, Collembola and Diplura are monophy, respectively, Protura and Diplura have the nearest realationship, they make sister groups with Collembola and all of them assemble with Insecta to make a monophy cluster of Hexapod; The results support the monophy of Pancrusracea, Crustacean is not a monophy cluster and the realationships between them with Hexapod need further reseachers.

对我国的14科27属30种跳虫的18S rDNA全序列和28S rDNA部分序列(D6-D7)的基因信息数据进行分析，结果支持原目、愈腹目的单系性，长角目不形成单系群，支持短角科从愈腹目中分出，但鳞总科和短角目的分类地位有待于深入分析探讨；进一步比对4种原尾虫、6种跳虫、5种双尾虫、5种昆虫和10种甲壳动物的18S rDNA全序列和28S rDNA全序列，以1种多足动物和1种螯肢动物为外群，进行系统关系分析，结果显示：原尾纲、弹尾纲、双尾纲分别为单系群，原尾纲和双尾纲优先聚为一支，然后和弹尾纲构成姐妹群，以上三类又和昆虫聚为一支，支持六足动物的单系性，支持泛甲壳动物，但甲壳动物并未形成单系，其各类群和六足动物之间的亲缘关系尚须进一步确定。3。

The fragments of mtDNA COI gene were sequenced for 11 species from 3 subfamilies of Cypraeidae, and the homologous sequences of another 17 species of Cypraeidae were downloaded from GenBank.
