Abstract

A new genus and species Yananphasma chresmodoides n. gen. n. sp. of susumaniid (Insecta) is described from the Middle Jurassic Yan’an Formation in China, based on a well preserved complete forewing. Our observation shows that these polyneopteran insects have narrow elongate forewings with parallel veins in their distal part, have a venation of phasmatodean type instead of archaeorthopteran type, with the median vein well separated from the radial vein and cubital vein and cubitus anterior emerging from the stem cubitus.
文章标题陕西中侏罗统水蚤科一新种(昆虫亚目:水蚤科)
根据保存完好的完整前翅,在中国中侏罗统延安组描述了sussusmaniid (insect)中的Yananphasma chresmodoides n. gen. n. sp一新属和新种。我们的观察表明,这些多翅目昆虫的前翅狭长,远端有平行的静脉,脉脉为phasmatodean型而不是archaeorthopteran型,中间静脉与径向静脉和肘静脉分离良好,前肘静脉从茎肘静脉中伸出。

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
