Genital shield smooth, distance between st 5 -st 5 63: 63 (61–64). Ventri-anal shield smooth, nearly pentagonal, with lateral margins slightly concave posterior to ZV 2; with three pairs of pre-anal setae and a pair of mesad to JV 2; 99: 102 (98–110) long, 83: 84 (82–86) wide at level of ZV 2, 79: 79 (76–82) wide at level of anus. Setae ZV 1, ZV 3 and JV 4 on integument surrounding ventri-anal shield. Setae JV 5 smooth; 40: 41 (40–42) long.

Chelicera ( Fig. 10View FIGURES 8 – 12). Movable digit 27: 27 (26–28) with three teeth, fixed digit 27: 28 (27–28) with 11–13 teeth.

Legs ( Fig. 12View FIGURES 8 – 12). With macrosetae smooth and pointed of the following lengths: Sge I 26: 26 (25–29), Sge II 26: 27 (26–28), Sge III 29: 29 (28–31), Sti III 22: 22 (21–22), Sge IV 43: 44 (42–47), Sti IV 23: 22 (22–23), St IV 47: 47 (43–50).

Type material. Holotype female, Nova Granada, on Albertia edulis (Rich.) A. Rich.  ( Rubiaceae  ), April 2009, P.R. Demite coll. Paratypes: one female, June 2008, P.R. Demite & A.C. Lofego colls., five females, March 2010, P.R. Demite & A.C. Lofego colls. All paratypes same host and locality as holotype.

Etymology. The specific name refers to city of Nova Granada, where the type specimens of this species were collected.

Remarks. This new species belongs to the obtusus species group and the andersoni species subgroup. Only two species of the andersoni subspecies group have s 4 <40 µm, Z 4 <50 µm and Z 5 <100 µm: Amblyseius leonardi McMurtry & Moraes, 1989  and A. neocrotalariae Gupta, 1978  . Females of the new species differ from A. leonardi  by having the macrosetae Sge IV and Sti IV smooth and pointed, and Sge IV 1.29 times as long. It differs from A. neocrotalariae  by having Sti IV 0.55 times as long, and in the shape of the spermatheca.
