Type species: Typhlodromus (Anthoseius) rickeri Chant, 1960

Species of this subgenus are characterised by having the dorsal shield well sclerotized, mostly reticulated, with 18 pairs of setae, setae s6 present, Z1 absent. Z4 and Z5 often thick and serrated and may be knobbed. Ventrianal shield with four pairs of preanal setae. Macrosetae present on genu, tibia and tarsus and often knobbed. Chant & McMurtry (1994) recognised 9 species groups viz., arizonicus, transvaalensis , singularis, daresalaami, rickeri , religiosus, rhenanus , egypticus and bergi under the subgenus Anthoseius based on the presence or absence of S4, JV3 and JV4; morphology of the dorsal setae and their lengths; shape of the female ventrianal shield and the point of insertion of setae r3 and R1. Among these species groups the present species Typhlodromus (Anthoseius) himaliniae sp. nov. belongs to transvaalensis species group due to absence of JV3, and long serrated dorsal shield setae; T. (Anthoseius) kanchanjanghai sp. nov. belongs to rickeri species group with dorsal setae j3, z3, s4, s6 and Z5 elongated while setae z2, z4 and S5 shorter.
