旗腹蜂总科化石研究进展

PROGRESS IN THE RESEARCH OF FOSSIL EVANIOIDEA (INSECTA, HYMENOPTERA)

旗腹蜂总科Evanioidea是膜翅目Hymenoptera在侏罗纪大辐射时出现的一个重要类群。自1910年Brues命名了早白垩世产于美国的旗腹蜂总科的化石昆虫Pristaulacus rohweri和Pristaulacus bradleyi以来,世界古昆虫学家发表了30余篇关于旗腹蜂总科昆虫化石的文章。共记载4科、8亚科、35属、110种,分布于18个国家。本文统计了世界已记载的旗腹蜂总科的化石名录、地理分布及地质年代,初步总结世界旗腹蜂总科昆虫化石的组成特征,提出旗腹蜂总科化石研究中存在的问题,及对未来研究的展望。

Evanioidea is an important Superfamily of Hymenoptera appeared during the Jurassic radiation. In 1910, Brues described two fossil species of Evanioidea, Pristaulacus rohweri and Pristaulacus bradleyi, from the Early Cretaceous of America. After Brues＇s work, nearly 30 papers dealing with the fossil Evanioidea of world have been published, describing 35 genera and 110 species assigned to 4 families and 8 subfamilies from 18 countries. A list summarizing all described Evanioidea fossils with their distribution and geological age and a chart showing numbers of the described Evanioidea fossils in different geological ages are provided. The characters of insect community are summarized. Some issues in this research field and prospects for future research are discussed.
