Abstract

Liang, J., Shih, C. & Ren, D., October 2017. New Jurassic predatory cockroaches (Blattaria: Raphidiomimidae) from Daohugou, China and Karatau, Kazakhstan. Alcheringa 42, 101–109. ISSN 0311-5518.

Two new species and a new combination in a new genus of predatory cockroaches, Falcatusiblatta gracilis and F. qiandaohua from the Middle Jurassic Jiulongshan Formation of Daohugou, China and F. karatavica (Vishniakova) comb. nov. from the Upper Jurassic Karabastau Formation of Karatau, Kazakhstan are described within Raphidiomimidae. The new taxa are distinguished by the presence of a very long ovipositor (plesiomorphy) and elongate cerci with heteronomous articles and forewing markings with irregular patch-like shapes of light and dark patterns (autapomorphies).
