Abstract

This study delves into the taxonomy of the stonefly family Peltoperlidae known from mid-Cretaceous Burmese amber. Based on a broad survey, the fossil family Petroperlidae Sroka, Staniczek & Kondratieff, 2018 is herein considered as a subfamily (Petroperlinae stat. nov.) within Peltoperlidae; and the subfamily Borisoperlinae Chen and Xu, 2020 syn. nov. is synonymized with Petroperlinae stat. nov. The diagnostic characters of all genera of Petroperlinae stat. nov. are revised and summarized. In addition, two new petroperline stoneflies, Graciloperla bulbosa gen. et sp. nov. and Graciloperla stylata gen. et sp. nov., are described based on male adults, which exhibit well-preserved aedeagal structures, the first known for fossil Peltoperlidae.

中白垩世缅甸琥珀Peltoperlidae的修正（昆虫亚目：翅翅目），附一新属两新种描述

本研究探讨了中白垩纪缅甸琥珀中已知的石蝇科Peltoperlidae的分类。根据广泛的调查，化石科Petroperlidae Sroka， Staniczek & & & Kondratieff， 2018被认为是Peltoperlidae中的一个亚科（Petroperlinae stat. 11 .）；Chen and Xu, 2020 syn11 .与Petroperlinae stat. 11同义。对Petroperlinae stat. 11各属的诊断特征进行了修订和总结。此外，本文还描述了两种新的石蝇，Graciloperla bulbosa gen. et sp. nov.和Graciloperla stylata gen. et sp. nov.，这两种石蝇基于雄性成虫，它们具有保存完好的aedeagal结构，这是在Peltoperlidae化石中首次发现的。

期刊介绍： Cretaceous Research provides a forum for the rapid publication of research on all aspects of the Cretaceous Period, including its boundaries with the Jurassic and Palaeogene. Authoritative papers reporting detailed investigations of Cretaceous stratigraphy and palaeontology, studies of regional geology, and reviews of recently published books are complemented by short communications of significant new findings. Papers submitted to Cretaceous Research should place the research in a broad context, with emphasis placed towards our better understanding of the Cretaceous, that are therefore of interest to the diverse, international readership of the journal. Full length papers that focus solely on a local theme or area will not be accepted for publication; authors of short communications are encouraged to discuss how their findings are of relevance to the Cretaceous on a broad scale. Research Areas include: • Regional geology • Stratigraphy and palaeontology • Palaeobiology • Palaeobiogeography • Palaeoceanography • Palaeoclimatology • Evolutionary Palaeoecology • Geochronology • Global events.
