摘要

本文描述了始新世波罗的海琥珀中已灭绝的针石蝇(针石蝇科，针翅目)Chen sp. nov.，并与其他针石蝇进行了比较。baleuuctra dewalti Chen sp. 11 .不同于现存的和已灭绝的leucidae代表，其形态特征包括翼脉、独特的终末结构和宫颈修饰。新分类群最明显的特征是在发育良好的肛门下探针的侧面有两个齿状长刺。在新石蝇身上还发现了几种寄生螨。这是目前所知的最早的关于羽翅目螨寄生的化石证据。这项研究检查了一块保存完好的始新世波罗的海琥珀，并发现了一种新的针石蝇，作为第二种已知的寄生于螨虫的波罗的海石蝇。为balleuctra foraminis Chen, 2018a和Euroleuctra gillesi Chen, 2018b提供了形态学比较的新信息。

A new needle stonefly with parasitic mites from the Eocene Baltic amber

Baltileuctra dewalti Chen sp. nov., a new extinct species of needle stoneflies (Leuctridae, Plecoptera), is described and illustrated from the Eocene Baltic amber and compared to the other leuctrids. Baltileuctra dewalti Chen sp. nov. differs from both extant and extinct representatives of Leuctridae by a combination of morphological characters including wing venation, unique terminalia structures, and cercal modification. The most distinguishable character for the new taxon is the presence of two dentate long spines lateral to a well-developed subanal probe. Several parasitic mites are also found on the new stonefly. This is the earliest known fossil evidence for mite parasitism in Plecoptera. This study examines a well-preserved piece of Eocene Baltic amber and discovers a new needle stonefly as the second known species of Baltileuctra which is parasitized by mites. New infor-mation is provided for Baltileuctra foraminis Chen, 2018a, and Euroleuctra gillesi Chen, 2018b, for morphological comparison.

期刊介绍： Acta Palaeontologica Polonica is an international quarterly journal publishing papers of general interest from all areas of paleontology. Since its founding by Roman Kozłowski in 1956, various currents of modern paleontology have been represented in the contents of the journal, especially those rooted in biologically oriented paleontology, an area he helped establish. In-depth studies of all kinds of fossils, of the mode of life of ancient organisms and structure of their skeletons are welcome, as those offering stratigraphically ordered evidence of evolution. Work on vertebrates and applications of fossil evidence to developmental studies, both ontogeny and astogeny of clonal organisms, have a long tradition in our journal. Evolution of the biosphere and its ecosystems, as inferred from geochemical evidence, has also been the focus of studies published in the journal.
