(Figure 1)  
 Diagnosis   
 This new species belongs to the americanus species group (Chant and McMurtry 2004), characterized as having the z4 longer than z2, at least 2 / 3 as long as the distance between its base and that of s4. Amblyseius ica sp. nov. also belongs to the dombeyus species subgroup, since it has an elongate and tubular calyx. This subgroup was previously represented by a single species, Amblyseius dombeyus (Denmark and Evans, 1999). The new species differs from A. dombeyus by having setae j3 and z4 shorter (0.5), and pre-anal pores placed posterior and longitudinally aligned with the base of setae JV2, whereas in A. dombeyus they are mesad and transversely aligned with the bases of setae JV2.   
 Specimens examined   
 Holotype female, from Rubus sp. (Rosaceae) leaves, 24 July 2008, Serra do Japí, Jundiaí, State of São Paulo, Brazil, 23 ◦ 11 ′ S, 46 ◦ 52 ′ W, P.R. Demite and J.C. de Souza colls. Paratypes: six females and one male, from same host, date and collectors as the holotype; two females and one male, 24 June 2009, from same host and collectors as the holotype; nine females from Melinis minutiflora Beauv. (Poaceae) leaves, 16 June 2009, A.C. Lofego coll. All paratypes from same locality as the holotype.

 Etymology   
 The specific name ica is the acronym of the “International Congress of Acarology”, in allusion to the XIII ICA, held in Brazil in August 2010.
