Discovery of five new species of from Yunnan and Hainan, China (Blattodea, Pseudophyllodromiidae).

We examined new materials from Yunnan and Hainan Province, China, and discovered new species using both morphological and molecular species delimitation (ABGD) methods. Five new species are described: Li & Wang, , Li & Wang, , Li & Wang, , Li & Wang, , and Li & Wang, All five species are placed under the species group. An updated key and checklist of species from China are provided.

Phylogenetic analysis of Blaberoidea reveals non-monophyly of taxa and supports the creation of multiple new subfamilies.

The superfamily Blaberoidea is a highly species-rich group of cockroaches. High-level blaberoidean phylogenetics are still under debate owing to variable taxon sampling and incongruence between mitochondrial and nuclear evolution, as well as different methods used in various phylogenetic studies. We here present a phylogenetic analysis of Blaberoidea based on a dataset combining the mitochondrial genome with two nuclear markers from representatives of all recognized families within the superfamily.
