The taxonomic position of Asian Holopedium (Crustacea: Cladocera) confirmed by morphological and genetic analyses

The cladoceran Holopedium gibberum Zaddach, 1855 (Ctenopoda: Holopediidae) was once thought to occur broadly in the northern hemisphere, but its cryptic sister species was recently separated from H. gibberum sensu stricto (s.s.) as a new species, Holopedium glacialis. In East Asia, although “H. gibberum” occurrence has been recorded in many water bodies, the identity of the surveyed populations has rarely been confirmed via molecular analyses....
