The Asian Species of Microcreagris Balzan (Pseudoscorpiones: Neobisiidae) Described by J.C. Chamberlin

Abstract

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.
