Abstract: Karstodiaptomus sheni n. gen., n. sp. is a new stygobiotic species of Calanoida (Crustacea: Copepoda), described from acave in Yunnan Province, China. It is the first record of stygobiotic calanoids from China and the fourth species from Asia.To accommodate the new species, a new genus, Karstodiaptomus n. gen., was erected. The new species is distinguishedfrom other representatives in the subfamily Speodiaptominae Borutzky, 1962 by the number of segments in the swimminglegs P1–P4 (Exp + Enp) as: 2+2, 2+2, 2+2, 3+2, the armature of the antennule, maxilla, maxilliped, and the structure ofthe fifth leg. The position of the new species in the subfamily Speodiaptominae is discussed, and a brief note on its ecologyis added.
