Neoseiulus viticolus Trincado & Martin, n. sp. (Figs 11–17) Diagnosis: This species is most similar to Neoseiulus brigarinus Beard, 2001, Neoseiulus cucumeris (Oudemans, 1930) and Neoseiulus noosae (McMurtry & Schicha, 1987). They all differ from the new species here described by having distinct atrium, and ventrianal shield much wider at level at ZV 2 than at level of anus. The former two species further differ by having three teeth on the fixed digit and one tooth on movable digit, while the latter further differs by having shorter Z 5. FEMALE: (4 specimens measured) Dorsum (Fig. 11). Dorsal shield reticulated, except for a transverse band between setae S 4 and S 5; with seven distinguishable pairs of pores and 11 pairs of lyrifissures; 398 (375– 412) long, 210 (205–218) wide; j 1 24 (23–25), j 3 26 (25–28), j 4 18, j 5 16 (15–18), j 6 19 (18–20), J 2 20, J 5 13, z 2 21 (20–23), z 4 23 (23–25), z 5 16 (15–18), Z 1 20, Z 4 43 (40–48), Z 5 56 (55–58), s 4 32 (30–35), S 2 29 (28–32), S 4 23 (20–25), S 5 23, r 3 24 (23–25), R 1 23 (20–25). All setae smooth, except for Z 4 and Z 5, serrate. Peritreme (Fig. 11). Extending forward almost to level of j 1. Venter (Fig. 12). Sternal shield smooth over most of its extent, with scant anterolateral striae; with three pairs of setae, and two pairs of lyrifissures; distances between St 1– St 3 71 (68–73), St 2– St 2 73 (68–78). Genital shield smooth; distance between St 5– St 5 81 (75–85). Ventrianal shield transversely striate in the anterior half and irregularly striate elsewhere, vase-shaped 136 (133–140) long, 92 (88–100) wide at ZV 2 level and 88 (85–90) at anus level, with three pairs of pre-anal setae and a pair of small, rounded pre-anal pores posteromesad of JV 2. Seta JV 5 41 (38–45). All ventral setae smooth. Two pairs of slender metapodal shields, the posterior distinctly larger. Chelicera (Fig. 13). Antiaxial lyrifissure distinct. Fixed digit 28 (25–30) long, with five teeth in addition to apical tooth and setiform pilus dentilis. Movable digit 31 (30–33) long, with two teeth in addition to apical tooth. Legs (Fig. 14). Macrosetae present only on leg IV, with tiny distal knob: Sge 29 (28–30), Sti 23, St 41 (38–45). Chaetotaxy of genu II 2 2/0, 2/0 1; genu III 1 2/1, 2/0 1. Spermatheca (Fig. 15). Calyx bell-shaped, 18 long. Atrium discrete. Male: (3 specimens measured) Dorsum. Dorsal shield similar to female; 311 (305–315) long, 212 (200–222) wide; j 1 21 (21–22), j 3 25 (23–26), j 4 16 (13–16), j 5 17 (15–18), j 6 17 (16–17), J 2 16 (16–17), J 5 11 (10–11), z 2 18 (17–18), z 4 24 (21–26), z 5 15 (14– 15), Z 1 19 (17–23), Z 4 34 (31–37), Z 5 42 (39–46), s 4 32 (27–36), S 2 22 (19–25), S 4 20 (19–21), S 5 20, r 3 22 (20–24), R 1 18 (16–20). All setae smooth, except for Z 4 and Z 5, serrated. Peritreme. Extending forward almost to level of j 3. Venter (Fig. 16). Sternogenital shield mostly smooth, with scant lateral striae; with five pairs of setae, and two pairs of liryfissures; distances between St 1– St 3 66 (66–67), St 2–St2 62 (61–62). Ventrianal shield reticulate, subtriangular, 188 (185–192) long, 141 (137–145) wide at anterior corners, with five pairs of pre-anal setae and a pair of small, rounded pre-anal pores posteromesad of JV 2. Metapodal shields indistinct. Chelicera (Fig. 17). Fixed digit 22 (21–22) long, with five teeth in addition to apical tooth and setiform pilus dentilis. Movable digit 20 (19–21) long, with one tooth in addition to apical tooth; spermadactyl with shaft 19 (15–21) and foot 8 (7–9) long. Legs. Macrosetae present only on leg IV, with tiny distal knob: Sge 21 (19–25), Sti 18 (15–19), St 33 (30–35). Etymology. The specific name viticolus refers to Vitis vinifera L., the plant species from which the types of this new species were collected. Type locality. Holotype female collected on 29 September 2009, from Pirque, Santiago Region, Chile, on Vitis vinifera L., associated with Brevipalpus chilensis Baker. Deposited at Departamento de Entomologia e Acarologia, Escola Superior de Agricultura “Luiz de Queiroz”, Universidade de São Paulo. One paratype female and one paratype male, same collection records as holotype; deposited at Departamento de Entomologia e Acarologia, Escola Superior de Agricultura “Luiz de Queiroz”, Universidade de São Paulo; two paratype females and one paratype male, same collection data as holotype, deposited at Museo Nacional de Historia Natural, Santiago to Chile.
