The four species of
Microcreagris first described by J. C. Chamberlin (1930) from China and Japan are transferred to the genus
Bisetocreagris Curcic and the type material is redescribed:
B. brevidigitata (Chamberlin) comb. nov.,
B. lampra (Chamberlin) comb. nov.,
B. orientalis (Chamberlin) comb. nov. and
B. silvestrii (Chamberlin) comb. nov. The type localities for the three species described from China are emended or clarified. Notes are given on
Bisetocreagris japonica (Ellingsen), which is also represented in the Chamberlin collection. The status of the genus
Chinacreagris Curcic, 1983 is discussed, and the genus is newly synonymized with
Bisetocreagris; the type species,
Microcreagris chinensis Beier, 1943, is newly synonymized with
B. silvestrii, and two new combinations are proposed:
B. kwantungensis (Beier, 1967) comb. nov., and
B. nankingensis (Curcic, 1983) comb. nov.
