Abstract
The Jurassic damsel-dragonfly family Paragonophlebiidae was till now monogeneric, with the sole genus Paragonophlebia and the two species P. inexpectata and P. patriciae, from the Middle Jurassic of Central Asia. Here we describe the new genus and species Sinagonophlebia yananensis Nel and Huang, from the Middle Jurassic of China, and we attribute the late Triassic and early Jurassic Diastatommites liassina (Strickland, 1840) from UK to the same family. We restore it in the genus Diastatommites Tillyard, 1925. We also describe the selenothemistid Yananthemis zaoyuanensis Nel and Huang, nov. gen., nov. sp., plus an isophlebiid gen. et sp. indet. from the same outcrop. These three damsel-dragonflies increase our knowledge on the already impressive diversity of the Odonata from the Mesozoic of China.
期刊介绍：
Geobios publishes bimonthly in English original peer-reviewed articles of international interest in any area of paleontology, paleobiology, paleoecology, paleobiogeography, (bio)stratigraphy and biogeochemistry. All taxonomic groups are treated, including microfossils, invertebrates, plants, vertebrates and ichnofossils.
Geobios welcomes descriptive papers based on original material (e.g. large Systematic Paleontology works), as well as more analytically and/or methodologically oriented papers, provided they offer strong and significant biochronological/biostratigraphical, paleobiogeographical, paleobiological and/or phylogenetic new insights and perspectices. A high priority level is given to synchronic and/or diachronic studies based on multi- or inter-disciplinary approaches mixing various fields of Earth and Life Sciences. Works based on extant data are also considered, provided they offer significant insights into geological-time studies.
