Abstract

Abstract: A new subfamily of Praesiricidae (Pamphilioidea), Decorisiricinaesubfam.n., is erected based on three new genera: Decorisiricius gen.n., Limbisiricius gen.n. and Brevisiricius gen.n. Two new species – Decorisiricius patulus gen. etsp.n. and D. longus sp.n. – from the Lower Cretaceous Yixian Formation and three species – Limbisiricius aequalis gen. etsp.n., Limbisiricius complanatus sp.n. and Brevisiricius partialis gen. etsp.n. – from the Middle Jurassic Jiulongshan Formation, are described. Based on these well‐preserved new fossil specimens and previously published data, the nonmonophyly of Praesiricidae is confirmed and the phylogenetic relationships of species of Praesiricidae are analysed for the first time. Two main clades within Praesiricidae are recognized from the cladistic analysis: Decorisiricinaesubfam.n. forms a monophyletic lineage, with the remaining members of Praesiricidae plus Megalodontes (Megalodontesidae) forming its sister group. The two subfamilies Archoxyelydinae and Praesiricinae are discarded with no strong supported synapomorphic characters based on phylogenetic research. A key to all genera of Praesiricidae is provided.
