Amblyseius duplicesetus Moraes & McMurtry

Amblyseius duplicesetus Moraes & McMurtry 1988: 13 ; Moraes et al. 2004a: 143, 2004b: 22 ; Zannou et al. 2007: 10 ; El­Banhawy & Knapp 2011: 25 . Amblyseius duplicisetus [sic], Chant & McMurtry 2004a: 208, 2007: 78.

Amblyseius duplicesetus belongs to the largoensis species group and to the largoensis species subgroup (Chant and McMurtry 2004a, 2007). It was found in Kenya ( Moraes and

McMurtry 1988; Zannou et al. 2007 ; El­Banhawy and Knapp 2011) and in Sri Lanka ( Moraes et al. 2004a). Its biology is totally unknown. This is the first mention of that species in Indian

Ocean Islands.

World distribution: Kenya, Sri Lanka.

Specimens examined: 18 specimens (13 ♀♀ and 5 ♂♂) collected during this study. Tsembehou, inside the village (446 m aasl, 12°12 ′ 27 ″ S, 44°27 ′ 54 ″ E), 1 ♀ on Mangifera indica L. ( Anacardiaceae ), 29/XI/2018 ; Chandra, inside the village (448 m aasl, 12°11 ′ 56 ″

S, 44°27 ′ 52 ″ E), 2 ♀♀ and 1 ♂ on Acalypha wilkesiana Müller Argoviensis (Euphorbiaceae) , 29/XI/2018 ; Pomoni, exit of the village (34 m aasl, 12°17 ′ 01 ″ S, 44°24 ′ 52 ″ E), 2 ♀♀ and

1 ♂ on Artocarpus heterophyllus Lamarck (Moraceae) , 1 ♀ and 1 ♂ on Artocarpus altilis (Parkinson) Fosberg (Moraceae) , 1 ♀ on Theobroma cacao L. ( Malvaceae ), 2 ♀♀ on Sygygium aromaticum (L.) Merrill and Perry ( Myrtaceae ) and 4 ♀♀ and 2 ♂♂ on an unknown tree with alternate leaves, 30/XI/2018.

Remarks: this is the second abundant species after P. horrifer but contrary to the later, the former was found in several sites. All measurements ( Table 2) fit well with those already published on this species with only very slight variations ( Moraes and McMurtry 1988 ; Moraes et al. 2004a ; Zannou et al. 2007 ; El­Banhawy and Knapp 2011). Measurements of female specimens of Anjouan are very similar with those collected from Kenya and Sri Lanka, except with shorter setae s4, Z4 and Z5. The male was already known, described and drawn by El­Banhawy and Knapp (2011) for the first time based on few measurements. We report here a complete set of measurements based on our 5 specimens to provide a full description ( Table 3).
