This species was described from Algeria (Athias­Henriot 1960). It is mainly known from the south of the Western Palearctic region. Euseius stipulatus is a common species reported from many plants, including cultivated plants such as peach, avocado and vines. It is especially abundant in citrus orchards ( Ragusa 1977, Ferragut et al. 1983, Papaioannou­Souliotis et al.

1994, Ragusa 2006, Kreiter et al. 2010, Sahraoui et al. 2012). Several studies have shown its ability to feed on pollen but also on pests such as T. urticae and P. citri or eriophyid mites

( Ferragut et al. 1992, Santaballa et al. 1994, Abad­Moyano et al. 2009, Pina et al. 2012).

Euseius stipulatus was already recorded in Madeira Island by Papadoulis and Kapaxidi (2011)

and Ferragut and Baumann (2020).

Remarks: the features and measurements of the adult female and male specimens collected in this study agree with those provided by Ferragut and Escudero (1997) and by Ferragut et al. (2010) for specimens from Spain. This is the most abundant (22% of the total number of phytoseiids collected) and frequent species (31% of total samples, just like for A. herbicolus which is similarly abundant) herein collected. As emphasized by Ferragut and Baumann (2020), the report of E. hibisci by Carmona (1973) should be considered a misidentification, as already suggested by Papadoulis & Kapaxidi (2011). Ferragut has examined specimens labelled as “ Amblyseius hibisci ” sent by M.M. Carmona and they were, in fact, E. stipulatus . Euseius hibisci must be removed from the species list reported in Madeira.
