摘要

褶翅目，俗称石蝇，是一种古老的水生昆虫，在淡水生态系统中具有重要的生态意义。本研究描述了石蝇的一个新属和新种 n. gen. n. sp.形态学检查揭示了......在分类学上属于石蝇亚目石蝇科（Arctoperlaria）的下目（Systellognatha）。独特的翅脉模式和生殖器结构将.与现存和已灭绝的石蝇科区分开来。为新石蝇建立了一个新的已灭绝化石科--Crossoperlidae n. fam.。这些发现有助于了解石蝇的进化、古多样性和生态适应性。

Taxonomy and evolutionary implications of a new fossil stonefly family (Insecta, Plecoptera) from Middle Cretaceous Kachin amber of northern Myanmar

Plecoptera, commonly known as stoneflies, represent an ancient order of aquatic insects with significant ecological importance in freshwater ecosystems. This study describes a new genus and species of stonefly, n. gen. n. sp., based on a female adult preserved in Middle Cretaceous Kachin amber. Morphological examination reveals the taxonomic placement of . within the infraorder Systellognatha of the suborder Arctoperlaria. Distinctive wing venation patterns and genitalic structures differentiate . from extant and extinct stonefly families. A new extinct fossil family, Crossoperlidae n. fam. is established for the new stonefly. The findings contribute to the understanding of stonefly evolution, palaeodiversity, and ecological adaptations.

期刊介绍： Palaeoworld is a peer-reviewed quarterly journal dedicated to the study of past life and its environment. We encourage submission of original manuscripts on all aspects of palaeontology and stratigraphy, comparisons of regional and global data in time and space, and results generated by interdisciplinary investigations in related fields. Some issues will be devoted entirely to a special theme whereas others will be composed of contributed articles. Palaeoworld is dedicated to serving a broad spectrum of geoscientists and palaeobiologists as well as serving as a resource for students in fields as diverse as palaeobiology, evolutionary biology, taxonomy and phylogeny, geobiology, historical geology, and palaeoenvironment. Palaeoworld publishes original articles in the following areas: •Phylogeny and taxonomic studies of all fossil groups •Biostratigraphy, chemostratigraphy, chronostratigraphy •Palaeoecology, palaeoenvironment and global changes throughout Earth history •Tempo and mode of biological evolution •Biological events in Earth history (e.g., extinctions, radiations) •Ecosystem evolution •Geobiology and molecular palaeobiology •Palaeontological and stratigraphic methods •Interdisciplinary studies focusing on fossils and strata
