ZooKeys 221: 19–29. doi: 10.3897/ zookeys.221.3207 Abstract Littoral dipluran Parajapyx pauliani Pagés, 1959 was redescribed based on the specimens collected in Hainan Island, South China. The littoral habitat was confirmed for the species, as the first report of arenicolous dipluran in China. DNA barcoding fragment was sequenced for five Parajapyx species (18 individuals) from China, and this is the first report on DNA barcodes used for dipluran identification. The mean intra- and interspecific divergences are 1.9% and 19.1% respectively. Synonymy of P. paucidentis and P. isabellae was confirmed. Keywords Diplura, Parajapyx, littoral, DNA barcodes analysis, China Introduction The genus Parajapyx was erected by Silvestri (1903) with type species P.
