The characteristics of the females collected in this study are very close to those of the holotype except for the longer r3 and R1. Denmark et al . (1999) considered this species to be a senior synonym of Euseius vivax (Chant & Baker ) . In this paper, these are considered distinct species, as explained under E . vivax . Euseius fructicolus is most similar to Euseius stipulatus (Athias-Henriot) from which it is distinguished by the shape and size of the spermatheca as mentioned later in this paper in the key to species.
