The specimen maybe Neoseiulus womersleyi if almost dorsal setae are long. In addition, Galendromus occidentalis is shown in this section as a morphological similar species to N. womersleyi, although G. occidentals is not indigenous but was introduced as a trial in the past (We cannot find today). N. womersleyi is clearly discriminated from G. occidentals by the arrangement of dorsal setae and shape of ventri-anal shield. （豊島・植物防疫(2012)に詳述）．
1. The specimen maybe Neoseiulus womersleyi (ケナガカブリダニ) if dorsal setaej3, z2, z4, s4 present, z3, s6 absent, and the length of dorsal seta j5 is longer than the distance between pores of j5 and j6. End of peritreme located near the dorsal seta j3. Ventri-anal shield looks like a pentagonal and a home plate of baseball.
2. Galendromus occidentalis (オキシデンタリスカブリダニ: 導入種) characterized by the dorsal setae (j3,z2,z3,z4,s4,s6), dorsal seta R1 is absent, dorsal seta j5 is shorter than the distance between pores of j5 and j6, peritreme is short, and ventri-anal shield shaped as a gourd or as a flower vase.
