Abstract

A new species of Archipsocidae, Archipsocus palaeosinicus n. sp., is described and illustrated from the middle Miocene Zhangpu amber. This taxon possesses all the synapomorphies of the Archipsocidae family and can be confidently classified within the genus Archipsocus due to its exceptional preservation, which allows for the detailed examination of the morphological traits used to define the genus and its species. Archipsocus palaeosinicus n. sp. is distinguished from other species of Archipsocus, inter alia, because of the first flagellomere that is shorter than the pedicel, a relatively flat antennal diagram, a unique arrangement of marginal setae on its fore- and hindwings, distinct venation patterns in both wings, and hindlegs with the first tarsomere longer than the second. The discovery of this species indicates that the genus Archipsocus likely had a broad distribution, with representatives in both China and Mexico during the Miocene.

中国中新世漳浦琥珀中发现的一种新的 Archipsocidae (Psocodea: Psocomorpha)

在中中新世张浦琥珀中描述并说明了猿科一新种——古猿猿（Archipsocus paleosinicus n. sp.）。该分类群具有长尾猿科的所有突触形态，由于其保存完好，可以自信地归类为长尾猿属，这使得对用于定义该属及其物种的形态学特征进行详细检查成为可能。古埃及Archipsocus paleosinicus n. sp.与其他Archipsocus物种的区别在于，除其他外，第一个鞭毛比花梗短，相对平坦的触角图，其前后翼边缘刚毛的独特排列，两翼的脉状模式明显，以及后腿的第一个跗端比第二个更长。这一物种的发现表明Archipsocus属可能具有广泛的分布，在中新世期间在中国和墨西哥都有代表。

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
