Abstract

Two new species, Helochares guoi Yang & Jia, sp. nov. and Helochares distinctus Jia & Tang, sp. nov., are described. Two species are recorded for the first time from China: Helochares negatus Hebauer, 1995 from Yunnan, and Helochares minusculus d’Orchymont, 1943 from Guangdong. Additional faunistic data from China are provided for the following species: Helochares hainanensis Dong & Bian, 2021, Helochares nipponicus Hebauer, 1995, Helochares sauteri d’Orchymont, 1943, Helochares densus Sharp, 1890, Helochares lentus Sharp, 1890, Helochares neglectus (Hope, 1854) and Helochares anchoralis Sharp, 1890. The Chinese fauna of Helochares comprises 16 species, 11 of which are illustrated in this contribution. Helochares crenatus Régimbart, 1921 is removed from the Chinese fauna.
