原尾纲重新分群的特征分析(六足总纲)

1996年第20届国际昆虫学大会（意大利佛罗伦萨）上，尹文英根据多年研究的新发现提出了原尾纲Protura分为3目10科的新建议，仅刊登在该次会议的论文摘要中，至今尚未能详细阐述重新分群的重要特征和分析。本文拟就原尾纲不同类群的成虫和幼虫主要特征进行分析和比较，结果证明原尾纲分为3目（Yuan目、华Yuan目和古Yuan目）10科，更符合原尾虫客观发展的自然规律。

ANALYSIS OF THE MAIN CHARACTERS FOR REGROUPING THE CLASS PROTURA(HEXAPODA)

The senior author, YIN Wen\|Ying suggested a new consideration on the higher taxa systematic of the Class Protura at the 20th International Congress of Entomology at Firenze, Italy in 1996. Only a brief abstract of this suggestion was published in the Proceedings of the Congress. The present paper deals mainly with the comparison of the important characters among the different groups of the Class Protura, and a cladistic analyses based on these characters. All the results support the new suggestion for regrouping the Protura into 3 orders: Acerentomata, Sinentomata and Eosentomata; subdivided into 10 families reflecting phylogenetic relationships in the Class Protura, and also improving the previous classical taxonomic system.
