This species belongs to the largoensis species group, and the largoensis species subgroup for the same reasons.
It is widespread in all tropical and subtropical regions of the world and was the most abundant species collected by Moraes et al. (2000) in French Caribbean Islands.
Using morphometric analyses of 36 characters, molecular analyses and crossing tests, Navia et al. (2014) studied specimens collected from 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.
World distribution: this species is widely distributed in the tropical and subtropical regions of Africa, America, Asia and the Pacific Islands.

Remarks: morphological and morphometric characters and all measurements fit well with measurement values given by Zannou et al. (2007) for specimens from Africa, Navia et al. (2014) for specimens from Brazil, La Réunion and Trinidad and Tobago an,d Ferragut and Baumann (2019) for specimens from Mauritius. This is of the three more numerous species collected during this study and probably one of the more common species on the island, with A. passiflorae and E. ovaloides.
