Rübsaamen无腹茧蜂（双翅目：瘿蚊科：Clinodiplosini）是一个主要是泛北极瘿蚊属，其物种与广泛的种子植物科，无论是作为瘿诱导剂或inquilines。在这项研究中，我们描述了来自日本的三种无腹二倍体：A。阿德托斯; sp.取食于马兜铃娃儿藤（Tylophora aristolochioides Miq.）（夹竹桃科）; A.空中列车。sp.诱导络石（Trachelospermum asiaticum（Sieb.）等Zucc。）Nakai和T.细柄变种liukiuense（夹竹桃科）;繁缕; sp.在Stellaria uliginosa Murray var. undulata（Thunb.）Ohwi（石竹科）。利用线粒体COI基因、核糖体16 S基因和核核糖体28 S基因对3个新种和GenBank中已发表的其它斜二孢属植物进行了系统发育分析。分析支持单系性的Ametrodiplosis，尽管变量的生活史的三个物种。此外，它表明很低的种内遗传分化的个体之间的不同地点和/或寄主植物。本文提供了三个日本新种的分类检索表。
Ametrodiplosis Rübsaamen (Diptera: Cecidomyiidae: Clinodiplosini) is a mostly Holarctic gall midge genus whose species are associated with a wide range of seed plant families, either as gall-inducers or inquilines. In this study, we describe three species of Ametrodiplosis from Japan: A. adetos n. sp. feeding in the flowers of Tylophora aristolochioides Miq.(Apocynaceae); A. aeroradicis n. sp. inducing aerial root galls on Trachelospermum asiaticum (Sieb. et Zucc.) Nakai and T. gracilipes var. liukiuense (Apocynaceae); and A. stellariae n. sp. forming leaf bud galls on Stellaria uliginosa Murray var. undulata (Thunb.) Ohwi (Caryophyllaceae). A molecular phylogenetic analysis using mitochondrial COI and ribosomal 16S genes and nuclear ribosomal 28S gene were conducted for the three new Ametrodiplisis species and other clinodiplosine taxa sequences available in GenBank. The analysis supported the monophyly of Ametrodiplosis despite the variable life history of the three species. In addition, it indicated very low intraspecific genetic divergence among the individuals from different localities and/or host plants. A taxonomic key to the three new Japanese species of Ametrodiplosis is provided.
