The Lasioseius phytoseioides species group (Acari: Blattisociidae): new characterisation, description of a new species, complementary notes on seven described species and a taxonomic key for the group.

The Lasioseius phytoseioides species group was first characterised over 50 years ago. Two species of this group, Lasioseius chaudhrii (Wu & Wang) and Lasioseius parberlesei Bhattacharyya, have been considered potentially effective as biological control agents of pest mites of the family Tarsonemidae on rice (Oryza sativa L.) in Asia.
