most abundant species collected by Moraes et al. (2000) in French Caribbean Islands and as a potential BCA of Raoiella indica Hirst in La Réunion Island ( Moraes et al. 2012). Using morphometric analyses of 36 characters, molecular analyses and crossing tests, Navia et al. (2014) studied specimens collected in Brazil, La Réunion Island and Trinidad and Tobago to determine whether A. largoensis populations from different geographic origins belong to the same taxonomic entity. Though differences in the lengths of some setae were observed, molecular analyses and crossing experiments indicated that populations from Indian Ocean and America were conspecific. This species was previously recorded from Mauritius Island by Ferragut and Baumann (2019) and Kreiter and Abo-Shnaf (2020b), and Rodrigues Island by Kreiter and Abo-Shnaf (2020a).

World distribution: this species is widely distributed in the tropical and subtropical regions of Africa, America, Asia and the Pacific Islands.

Specimens examined: 17 specimens in total, 8 ♀♀, 4 ♂♂ and 5 im. L’Abattoir,

Dziani lake (23 m aasl, 12°46 ′ 14 ″ S, 45°17 ′ 18 ″ E), 1 ♂ and 2 im. on Phoenix dactyliphera

L. ( Arecaceae ) and 1 ♂ on Artocarpus altilis (Parkinson) Fosberg (Moaceae) 27/XI/2018; L’Abattoir, City Center (15 m aasl, 12°47 ′ 18 ″ S, 45°16 ′ 21 ″ E), 2 ♀♀ and 1 im. on Mangifera indica L. ( Anacardiaceae ), 3 ♀♀ and 2 ♂♂ on Hibiscus rosa-sinensis (Malvaceae) with eriophid mite galls, and 3 ♀♀ and 2 im. on Cordia sebestena (Boraginaceae) , 27/XI/2018.

Remarks: morphological and morphometric characters and all measurements of Mayotte Island specimens fit well with those given in Zannou et al. (2007) for specimens from Africa, Navia et al. (2014) for specimens from Brazil, La Réunion and Trinidad & Tobago and Ferragut and Baumann (2019) for specimens from Mauritius. This is the third more common species of our samplings.
