Redescription of arenicolous dipluranParajapyx pauliani (Diplura Parajapygidae) and DNA barcoding analyses ofParajapyx from China

摘要

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 divergencesare 1.9% and 19.1% respectively. Synonymy of Parajapyx paucidentis and Parajapyx isabellae was confirmed.
