Synopsis An intriguing new genusand species of cockroach (Blattodea), Raphidiomimula burmitica, is described in Cretaceous amber from Myanmar. Raphidiomimidae previously were known only as compression fossils from the Upper Jurassic (Kimmeridgian) of Karatau, Kazakhstan. The structure of the cockroaches, including the apparently raptorial forelegs of Raphidiomimula, suggests they were predatory. The new fossil has several features that are apomorphic and others that are plesiomorphic with respect to the two previously known genera, Raphidiomima and Cameloblatta. The relationships of Raphidiomimidae to other Blattodea and Dictyoptera remain obscure.
