摘要

在坦桑尼亚中北部马亨德的一个丰富的始新世（~45.6 mya）maar Lagerstätte，描述了一个scarabaeoid化石（鞘翅目：Scarabaoeidea）Mahengea mckayi新属、新物种——唯一保存完好的昆虫化石，也是在该遗址发现的少数昆虫之一。许多鱼类和植物化石已从该遗址中找到并进行了描述。考虑到昆虫化石在其他起源和年龄相似的矿床中的丰富性，昆虫化石的缺乏令人惊讶。我们认为，在前火山口湖富含氧气的水域中，丰富的鱼类可能已经清除了大部分落入水中的陆地昆虫。尽管这里描述的化石无疑是Scarabaeoidea的一员，但其家族位置仍不确定。

An Eocene fossil scarab beetle (Coleoptera: Scarabaeoidea) from Tanzania

A fossil scarabaeoid (Coleoptera: Scarabaeoidea) Mahengea mckayi new genus, new species – the only well-preserved insect fossil and one of only a few insects found at the site – is described from an otherwise rich Eocene (~ 45.6 mya) maar Lagerstätte at Mahenge in central northern Tanzania. Numerous fossil fishes and plants have been recovered from this site and described. The dearth of insect fossils is surprising considering their richness in other deposits of similar origin and age. We suggest that the rich fish fauna present in the oxygen-rich parts of the water in the former volcanic crater lake may have scavenged most of the terrestrial insects that fell into the water. Although the fossil described here is undoubtedly that of a member of the Scarabaeoidea, the family placement remains unsure.

期刊介绍： The South African Journal of Science is a multidisciplinary journal published bimonthly by the Academy of Science of South Africa. Our mandate is to publish original research with an interdisciplinary or regional focus, which will interest readers from more than one discipline, and to provide a forum for discussion of news and developments in research and higher education. Authors are requested to write their papers and reports in a manner and style that is intelligible to specialists and non-specialists alike. Research contributions, which are peer reviewed, are of three kinds: Review Articles, Research Articles and Research Letters.
