襀翅目化石的研究进展

回顾中国及世界襀翅目化石研究进展,列出已发表的化石种类名录、分布及年代,共19科、85属、225种;襀翅目化石世界分布,但主要集中在前苏联地区,中国仅14种.不同地质年代发现的襀翅目种类、数量和特征不同.本文并简要介绍稚虫食性、系统学、古地理和古生态等方面的研究成果,并初步分析了研究中存在的一些问题和今后需要解决的问题.

PROGRESS IN THE STUDY OF PLECOPTERA FOSSILS

The history, status quo and some problems on the taxonomic researches of Plecoptera fossils are reviewed in this paper. A checklist of fossil Plecoptera, with their distribution and geological age are provided. Up to now, 19 families, 85 genera, 220 species and 5 indefinitive species have been reported, which were founded in the entire world, but most of them were distributed in former USSR region, only 14 species were recorded in China. Number and abundance of Plecoptera fossils are diverse during the different geological age. Phylogenetic system, feeding habits of nymphs, paleogeography and paleoecology of fossil stoneflies are summarized briefly. The present contradicting proposals and problems are far from being resolved, a comprehensive research of Plecoptera should be taken into consideration in our future work.
