Taxonomic Position

Cohort Gamasina

    Subcohort Dermanyssiae

  Superfamily Phytoseioidea

Family Phytoseiidae Berlese

Subfamily Typhlodrominae Chant & McMurtry

Galendromus (Galendromus) Muma

(syn. = Metaseiulus, Typhlodromus in part)

 

Diagnostic characters: Typhlodrominae, Metaseiulini (setae s6 present; z3 usually present; z6, S4 and JV4 absent) with:

 

Similar taxa.  Phytoseiinae lack setae Z1, S2, S4 and S5.  Amblyseiinae lack both setae z3 and s6Ascids usually have dorsal shields with 22 or more pairs of setae and only rarely (e.g. Blattisocius) have phytoseioid-like corniculi.  Within the Metaseiulini only Galendromus have setae R1 absent and S2 present; Galendromus (Mugidromus) species have shorter dorsal setae and setae j3 inserted well behind setae j1.

 

Ecology & Distribution. Species of Galendromus are found primarily in Central America and the southern United States, but species used in biological control of spider mites (e.g. G. occidentalis) have been introduced around the world.
