摘要

在中生代时期，人工构形甲虫科Ommatidae具有高度的多样性。尽管它们曾经具有很高的分类多样性和形态差异，但许多中生代杂交虫分类群仍然知之甚少，部分原因是保存有限。在这里，我们报告了一个保存非常完好的化石，我们将其描述为一个新的ommatid属和种，Limnomma daohugouensegen。et sp. nov.，来自中国东北中侏罗统稻虎沟Lagerstätte。这个新属可以很容易地从其他单胞虫中区分出来，因为在腹体5上有一个圆形的非结核区域。讨论了这一新分类群与中生代Brochocoleus属和Burmocoleus属的分类关系。

Limnomma, a new genus of Ommatidae from the Middle Jurassic Daohugou beds (Coleoptera, Archostemata)

The relictual archostematan beetle family Ommatidae attained high diversity during the Mesozoic. Despite their once high taxonomic diversity and morphological disparity, many Mesozoic ommatid taxa remain poorly understood, partly due to limited preservation. Here we report an exceptionally well-preserved fossil, which we describe as a new ommatid genus and species, Limnomma daohugouensegen. et sp. nov., from the mid-Jurassic Daohugou Lagerstätte in Northeast China. The new genus can be most easily distinguished from other ommatids by the presence of a circular non-tuberculate region on ventrite 5. The new taxon is discussed in relation to the classification of the Mesozoic genera Brochocoleus and Burmocoleus.

期刊介绍： Founded in 1857 as Berliner Entomologische Zeitschrift, Deutsche Entomologische Zeitschrift is one of the World''s oldest international journals of systematic entomology. It publishes original research papers in English on the systematics, taxonomy, phylogeny, comparative morphology, and biogeography of insects. Other arthropods are also considered where of relevance to the biology of insects. The geographical scope of the journal is worldwide. Deutsche Entomologische Zeitschrift (DEZ) is dedicated to provide an open access, high-quality forum to contribute to the documentation of insect species, their distribution, their properties, and their phylogenetic relationships. All submitted manuscripts are subject to peer-review by the leading specialists for the respective topic. The journal is published in open access high-resolution PDF, semantically enriched HTML and machine-readable XML versions.
