Species delimitation of cockroaches from China, with seven new species (Blattodea, Ectobiidae, Pseudophyllodromiinae).

Nearly 450 specimens were collected from 27 locations in China and their morphology was examined. Then 68 sequences were obtained and used to carry out phylogenetic analyses as well as species delimitation analyses using General Mixed Yule Coalescent (GMYC), Automatic Barcode Gap Discovery (ABGD), and Poisson Tree Processes (bPTP). GMYC analysis resulted in 21 molecular operational taxonomic units (MOTUs) (confidence interval: 20-22), which was completely consistent with the result of the bPTP.

New record of Uvarov, 1939 (Blaberidae, Epilamprinae) from China, with three new species based on morphological and COI data.

The genus Uvarov, 1939 (Blaberidae, Epilamprinae) is recorded for the first time from Hainan Island, China. Three new species, Wang & Wang, , Wang & Wang, , and Wang & Wang, , are described based on morphological data and a molecular analysis using Automatic Barcode Gap Discovery (ABGD). Additional barcode data of blaberid species, including these three new species, are provided to facilitate future species identification.
