Taxonomy and phylogeny of three euplotid ciliates isolated from northeast of China: Euplotes heilongjiangensis n. sp., E. daqingensis n. sp., and E. cf. daidaleos (Alveolata, Ciliophora, Euplotida)

As a new addition, two new Euplotes species have been published and added to the genus based on their live morphology, infraciliature and silverline system. Furthermore, the genetic data were also added and a reliable identification for environmental monitoring and resource investigations were provided.
