description: Neoseiulus neomarginatus n. sp.
Diagnosis. This new species belongs to the barkeri species group, with the atrium of the spermatheca forked at the juncture with the major duct, and to the womersley species subgroup of Schicha, by having the atrium enlarged, deeply forked at the juncture with the major duct, joined to the calyx by a stalk; calyx V-shaped. It is similar to N. neoaurescens Moraes & Mesa, N. cinctutus (Livshitz & Kuznetsov), N. marginatus (Wainstein) and N. scapilatus (Van der Merwe) which are also members of the same species subgroup. Differences between Neoseiulus neomarginatus n. sp. and the related species are summarised in Table 2.

Female (n = 8). Dorsum (Figure 6). Dorsal setal pattern 10A:9B (r3 and R1 on interscutal membrane). Dorsal shield oval with waist, sclerotised, smooth, with a few lateral striations, bearing seven pairs of solenostomes (between j3 and z2, anteromedian to z4, posteromedian to z5, posterior to s4,anteromedian to Z1, anteromedian S4 and anterior to S5); six pairs of small pores (sensilla) visible on dorsal shield; muscle-marks (sigilla) visible, mostly on podosoma, length of dorsal shield (j1–J5) 314 (305–325), width (distance between bases of s4) 149 (135–158) (distance between bases of S2) 175 (158–186). All dorsal setae smooth except for Z4 and Z5, which are slightly serrated. Measurements of dorsal setae as follows: j1 15 (14–16), j3 23 (20–26), j4 16 (14–18), j5 14 (12– 16), j6 16 (14–16), J2 20 (20–22), J5 10 (10–12), z2 22 (22–26), z4 24 (22–24), z5 14 (12–16),Z1 24 (22–26), Z4 45 (42–46), Z5 51 (49–53), s4 33 (32–38), S2 32 (30–36), S4 30 (24–32), S5 21 (20–22), r3 22 (20–24) and R1 21 (18–26).
Peritreme. Extending to level between setae j1 and j3.
Venter (Figure 7). Ventral setal pattern 14:JV–3:ZV. Sternal shield smooth, slightly sclerotised, with three pairs of setae (ST1, ST2 and ST3) and two pairs of pores (pst1 and pst2); length (ST1–ST3) 62 (59–65), width (distance between setae ST2) 64 (61–69); metasternal setae ST4 and a pair of pores (pst3) on metasternal shields. Genital shield smooth; width at level of genital setae (ST5) 63 (59–67). Ventrianal shield pentagonal, with transverse striae, with three pairs of preanal setae (JV1, JV2 and ZV2), anal setae (a1, a2 and a3), one pair of small solenostomes posteromedian of JV2 and sigilla posterolaterally. Length of ventrianal shield 113 (103–119), width 108 (101–115). Setae JV4, JV5, ZV1, ZV3 and seven pairs of pores on integument surrounding ventrianal shield. Setae JV5 smooth, much longer than others 43 (38–49) in length.
Chelicerae (Figure 8). Fixed digit 28 (26–30) long with three visible teeth, with pilus dentilis; movable digit 29 (28–32) long with one tooth.
Spermatheca (Figure 9). Calyx V-shaped 13 (12–16) in length; atrium enlarged, deeply forked at juncture with major duct, joined to calyx by a stalk, minor duct not visible.
Legs (Figure 10). Length of legs (base of coxae to base of claws): leg I 341 (333–352); leg II 246 (238–257); leg III 246 (238–257); leg IV 328 (317–344). GeII, GeIII and GeIV with eight, seven and seven setae respectively; BtIV with one macroseta 66 (61–69) in length.
Male. Unknown.
Type material. Holotype female and two female paratypes collected at Pithari, Co. Chania, Crete Island, 24 April 2011, on Anchusa sp. (Boraginaceae). Two female paratypes collected at Iolkos, Co, Magnisia, Thessalia, 18 December 2011, on litter under Pinus sp. (Pinaceae); three female paratypes collected at Hymettos Mountain, Co, Attiki, Sterea Hellas, 18 March 2012, on moss.
Etymology. The name of this new species is derived from the closely related species N. marginatus.
