Exploring the relationship of and (Blattodea, Blattidae, Blattinae) from a morphological and molecular perspective, including a description of four new species.

This study utilized six genes (, , , , and ) from a total of 40 samples to construct maximum likelihood (ML) and Bayesian inference (BI) phylogenetic trees in order to infer the relationships between the morphologically similar genera Stål, 1874 and Bey-Bienko, 1957. The phylogenetic analysis showed the two genera have a close relationship and were recovered as sister groups based on ML and BI analyses. Four new species are described among these samples, i.e., sp. nov., sp. nov., sp. nov. and sp. nov. based on morphological and data. A key to the worldwide is provided.
