摘要

The genus Arrhenoseius Walter & Lindquist, 2000 is recorded for the first time from the Oriental Realm on the basis of two new species. Arrhenoseius hallidayi sp. 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 granulatus sp. 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.
