Diplogyniopsis fluctuosumsp. nov. associated with passalid beetles is described based on females from China on undermined passalid beetles, as well as on females and males from Thailand on Aceraius helferi (Coleoptera: Passalidae). The species represents the second known species of Diplogyniopsis Trägårdh, prompting us to redefine the genus diagnosis. [ABSTRACT FROM AUTHOR]

The genus Arrhenoseius Walter & Lindquist, 2000 is recorded for the first time from the Oriental Realm on the basis of two new species. Arrhenoseius hallidayisp. nov. can be distinguished from other species of the genus by the ventrianal shield bearing five pairs of ventral setae and unsclerotised ventro-lateral cuticle without setae in the adult female, and Arrhenoseius granulatussp. nov. can be distinguished by the ventrianal shield bearing eight pairs of ventral setae and unsclerotised lateral cuticle with six pairs of setae. A key to species of Arrhenoseius is given based on the adult females. [ABSTRACT FROM AUTHOR]
