蜉蝣目化石的研究进展

回顾了世界蜉蝣目化石研究简史,列出已发表的化石种类名录、分布及年代,共40科、124属、218种,其中包括中国的8属13种;描述了不同地质时期主要蜉蝣化石的分类单元和分布地区.简要介绍了蜉蝣分类系统及系统发育、稚虫食性、与其它昆虫的关系和古生态等方面的研究成果.在本文的第2部分,初步分析了目前该类群所存在的一些问题,并对今后的研究工作进行了展望.

PROGRESS IN THE STUDY OF EPHEMEROPTERA (MAYFLY) FOSSILS

This paper reviews the history and current status of the research on Ephemeroptera fossils from 7 aspects. Up to now, 40 families, 124 genera, 218 species of fossils have been reported from all over the world, including 8 genera and 13 species from China. A checklist of all described Ephemeroptera fossils, with their distribution and geological age is provided. Mayfly diversity and distribution during the main geological epoch are introduced. Phylogeny and higher classification of mayflies, feeding habits of nymphs, relationship with other insects, palcoecology and important value in biostmfigraphic correlation are briefly summarized. In the second part, some problematical issues in this research field are enumerated, such as association of mayfly imago and nymph, validity of some known species etc. An integrative and thorough study of mayfly should be taken into consideration in future.
