Abstract
The tribe Amblyseiini Wainstein is diagnosed and 3 new subtribes are proposed: Amblyseiina n. subtribe, Proprioseiopsina n. subtribe, and Arrenoseiina n. subtribe. The subtribe Amblyseiina is reviewed in detail. Three new genera are proposed: Transeius n. gen., Maunaseius n. gen., and Graminaseius n. gen. The established genera are: Amblyseiella Muma, Amblyseius Berlese, Chelaseius Muma and Denmark, and Honduriella Denmark and Evans. Keys to the genera in the subtribe Amblyseiina are provided and exemplar species are figured. We propose a cladogram suggesting the relationships between the 3 subtribes in the Amblyseiini and between the constituent genera in the Amblyseiina.
