Other Names



Distributed throughout Asia: Japan, South Korea, Taiwan (Moraes et al., 2004); Australia: Tasmania, Victoria, NSW, ACT, Queensland (Schicha, 1987; Beard, 2001); New Zealand (Ho et al., 1995).


N. womersleyi is very similar to Neoseiulus longispinosus (Evans). The two species can be distinguished by examining the dorsal seta S5 - it is long (as long as S4) and barbed in N. womersleyi, and short (much shorter than S4) and smooth in N. longispinosus. The two species are often misidentified. Collyer (1982) noted that the length of seta S5 is very variable, and suggested that N. womersleyi is a junior synonym of N. longispinosus, but her opinion was not supported in later taxonomic publications. It is likely that some of Collyer's "N. longispinosus" were in fact N. womersleyi. Schicha (1987) and Beard (2001) list N.womersleyi as common in Australia on a wide range of herbaceous plants and small shrubs, including strawberry, black currant, and pot plants. This species is often found in association with the two-spotted mite, Tetranychus spp.
