Updated checklist and distribution of the diaptomid copepods (Copepoda, Calanoida, Diaptomidae) of China

We present an updated checklist of the Diaptomidae of China, based on a literature review and on original field data from all over China during 2012-2016. A total of 19 genera and 56 species have been recorded. Neutrodiaptomus has the highest species richness (10 species), followed by Arctodiaptomus (9 species). Only one species each of Eudiaptomus , Mixodiaptomus , Eodiaptomus , Dentodiaptomus , Dolodiaptomus , Allodiaptomus , Karstodiaptomus , Metadiaptomus and Paradiaptomus was found. The taxonomic status of 16 species was revised: one wrongly attributed genus, Argyrodiaptomus , was corrected to Sinodiaptomus . First records for China include Arctodiaptomus parvispineus and one new cave-dwelling genus, Karstodiaptomus , is added. One Latin name from Shen & Sung’s book (1979) is corrected. Remarks on nomenclature and taxonomic issues are supplemented with information on the geographical distribution of the various species within China.
