The pseudoscorpion genus Haplochernes Beier, 1932, is redescribed and restricted to those species of Chernetidae with only four setae on the cheliceral hand and a pair of moderately long, slender spermathecae. This new definition is shared by only two species: the type species H. boncicus (Karsch, 1881) from Japan and possibly Taiwan and H. wuzhiensis Gao and Zhang sp. nov. from Hainan Island, China. Haplochernes madagascariensis Beier, 1932 from Madagascar and H. hagai Morikawa, 1953 from Japan are treated as new synonyms of H. boncicus.
