Amblyseius largoensis belongs to the largoensis species group and to the largoensis species subgroup. It is widespread in tropical and subtropical regions of the world and was the most abundant species collected by Moraes et al. (2000) in French Caribbean Islands and an important species 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 is its first record in French Guiana.

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

Specimens examined: sixteen specimens (13 ♀♀, 1 ♂ and 2 imm.) collected during this study. Saint-Laurent-du-Maroni, Chemin de Mana (20 m aasl, lat. 5°29 ′ 18 ″ N, long. 52°35 ′ 00 ″ W), 1 ♀ and 1 imm. on Musa parasidiaca L. ( Musaceae ), 27/X/2001 ; Île du Salut

(3 m aasl, lat. 5°17 ′ 01 ″ N, long. 53°58 ′ 02 ″ W), 2 ♀♀ on Cocos nucifera L. ( Arecaceae ), 4

♀♀ on an unknown hostplant, 5 ♀♀ on M. paradisiaca , 1/XI/2001, 1 ♀, 1 ♂ and 1 imm. on Capsicum frutescens L. ( Solanaceae ), 2/XI/2001.

Remarks: morphological and morphometric characters and all measurements fit well the measurement given by Navia et al. (2014) for specimens from Brazil, La Réunion and Trinidad

& Tobago.
