Diagnosis. Female. Body length 351-421 and width 208- 277 μm. Dorsal shield smooth, with light anterolateral lineation; all dorsal setae short, thin, smooth; Z5 smooth, may have 1-2 small barbs. Sternal shield smooth. Ventrianal shield with pair small round pores, distance between pores 37-38. Fixed digit of chelicera with five or six teeth, two anterior and three or four posterior teeth; movable digit with one strong tooth and a bump, may be a second vestigial tooth. Calyx of spermathecal apparatus long, narrow, tubular, parallel-sided basally and arms diverging strongly distally to form V-shape (trumpetshaped); atrium large, as broad as junction with major duct; major duct membranous, broad near atrium and narrowing towards sperm-induction pore. Leg IV with long setaceous macroseta on basitarsus. Dorsal adenotaxy: gd 2, gd 5, gd 8 not visible, gd 4 present.

Remarks. The first description of this species was based on three adult females collected from weeds in an apple orchard on the North Island of New Zealand by Collyer (1964b). Unfortunately, the original illustration and specimen descriptions lacked fine details and provided no clear understanding of this species. Thus, Schicha (1980) later re-described the species after remounting female lectotypes collected by Collyer. Schicha (1983) and Beard (2001) provided additional morphological and biological data after finding the species in Australia. Beard (2001) described this species on apple trees and orchard groundcover (in Tasmania), and in litter beneath apples (in New South Wales). Schicha (1983) synonymiz- ed Amblyseius salish Chant and Hansell with N. harrowi in a comparative study of neighboring species, although this identity is difficult to confirm because the peritreme of A. salish reaches almost to the level of j 3 ( Chant and Hansell, 1971), whereas that the peritremes of N. harrowi extends to the base of j 1 ( Amano et al., 2011). Ragusa and Athias-Henriot (1983) suggested that N. harrowi (Collyer) was synonymous with N. agrestis ( Karg, 1960) , but limited data currently prevent the confirmation of this synonymy.
