All setae smooth, except Z4 and Z5 which are serrated. Peritreme extending forward to the level of j1.
Venter (Fig. 9). Sternal shield smooth, with three pairs of setae and two pairs of lyrifissures; distance between st1-st3 57: 58 (56–60) and between st2-st2 63: 65 (63–67). Genital shield smooth, distance between st5-st5 63: 63 (61–64). Ventri-anal shield smooth, nearly pentagonal, with lateral margins slightly concave posterior to ZV2; with three pairs of pre-anal setae and a pair of mesad to JV2; 99: 102 (98–110) long, 83: 84 (82–86) wide at level of ZV2, 79: 79 (76–82) wide at level of anus. Setae ZV1, ZV3 and JV4 on integument surrounding ventri-anal shield. Setae JV5 smooth; 40: 41 (40–42) long.
Chelicera (Fig. 10). Movable digit 27: 27 (26–28) with three teeth, fixed digit 27: 28 (27–28) with 11–13 teeth.
Spermatheca (Fig. 11). Cervix cup-shaped; 5: 6 (5–7) long, atrium nodular.
Legs (Fig. 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). Chaetotactic formula of genu II: 2-2/0-2/0-1 and genu III: 1-2/1-2/0-1.
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 s4 <40 µm, Z4 <50 µm and Z5 <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.
