Key characteristics of species in this genus are: dorsal shield rotund, coarsely punctate or lightly imbricate; idiosomal setal pattern 10A:6D/JV-3:ZV±3; setae J2, S4, S5 absent, and seta ZV3 absent from all but Asperoseius baguioensis Corpuz-Raros, 1994 (members of the heveae species group of the genus Amblyseiulella Muma have the same dorsal setal pattern but seta ZV3 is always present); many dorsal setae short, subequal, strongly serrate, flattened; without prominent pores associated with z5; peritreme extending to level of j1; posterior margin of sternal shield concave; posterior margin of genital shield round to truncate; female ventrianal shield much longer than wide, approximately rectangular, without marked waist; preanal pores minute; imaginary line connecting minute ZV2, JV1 and JV2 forming an acute angle; calyx of spermatheca cupshaped; fixed cheliceral digit with few teeth; legs I–III with many short and thickened setae, but without true macrosetae; leg IV with 2 or 3 stout, elongate macrosetae with tips expanded, flattened.

Both species reported in this paper have preanal pores well separated.
