(2021) ( Fig. 3 : A–E) Female– One specimen measured. Idiosomal setal pattern: 10A:9B/JV–3:ZV. Dorsal idiosoma ( Fig. 3A ) – Dorsal shield oval, slightly constricted at R 1 level, 425 long and 288 wide at j6 level, smooth with some striae anterolaterally; with 19 pairs of dorsal setae ( r 3 and R 1 included); dorsal shield setae smooth, except for Z 4 and Z 5 , slightly serrated; lengths: j 1 38, j 3 46, j 4 8, j 5 6–7, j 6 8, J 2 9, J 5 9, z 2 14, z 4 15, z 5 8, Z 1 13, Z 4 115, Z 5 263, s 4 101, S 2 11 , S 4 11 , S5 8 ; setae r 3 14 and R 1 10 on lateral integument; Z 4 , Z 5 and s 4 are the longest, dorsal shield with 7 pairs of solenostomes ( gd 1 , gd 2 , gd 4 , gd 5 , gd 6 , gd 8 , gd 9 ) and 11 pairs small poroids. Peritreme – Extending almost beyond setae j 1 ( Fig. 3A ). Ventral idiosoma ( Fig. 3B ) – Sternal shield slightly wider than long, posterior margin straight, smooth at the central area with a few lateral striae, 79 long, 87 wide at level of setae ST 2 , three pairs of setae and two pairs of pores ( iv 1 and iv 2 ), ST 1 41, ST 2 35, ST 3 33;distances between ST 1 –ST 3 76 and ST 1 –ST 1 71, ST 2 –ST 2 79; metasternal setae ST 4 33 and a pair of pores ( iv 3 ) on small platelets; genital shield smooth width at widest point 82, ST 5 33; two pairs of metapodal shields, primary 26 long and accessory 17 long; ventrianal shield smooth vase-shaped ( Fig. 3B ), length 133, width at level of setae ZV 2 , 68, and width at level of paranal setae 74; with three pairs of preanal setae ( JV 1 27, JV 2 25, ZV 2 21); four pairs of setae surrounding ventrianal shield on integument ( JV 4 11, JV 5 71, ZV 1 20, ZV 3 11), five pairs of pores surrounding ventrianal shield. Ventrianal shield with a pair of elliptical pores ( gv 3 ) posteromesad to JV 2 , distance between these pores 32. Spermatheca – Calyx elongate 35 long, 4 in diameter at the middle part of the calyx; one-third of calyx wall toward vesicle much thinner than the rest; atrium relatively large and C-shaped ( Fig. 3D ). Chelicera – Fixed digit 30 long with about 10 teeth and a pilus dentilis; movable digit 33 long with 4 teeth ( Fig. 3C ). Legs – Leg IV ( Fig. 3E ) with three pointed macrosetae, SgeIV 111, StiIV 87, StIV 70; length of macrosetae on other legs: SgeI 44, SgeII 40, SgeIII 47; length of legs from the base of coxae to the tip of claws: leg I 311, leg II 233, leg III 256, leg IV 321; chaetotactic formulae of genua and tibiae I–II–III–IV with 10(2-2/1, 2/1-2) – 7(2- 2/0, 2/0-1) – 7(1-2/1, 2/0-1) – 7(1-2/0, 2/1-1) and 10(2- 2/1, 2/1-2) – 7(1-2/1, 1/1-1) – 7(1-1/1, 2/1-1) – 6(1-1/0, 2/1-1) setae respectively. Distribution – Many tropical and subtropical countries (see Demite et al., 2021 ). Specimen examined – One female , 12 November 2015 , Phoenix sp. , in greenhouse, Hortus Botanicus Amsterdam , The Netherlands ( 52°22’00.4”N 4°54’25.8”E ), collector: Farid Faraji. Remarks – It seems that Amblyseius herbicolus has a well-established population in the greenhouse of Hortus Botanicus Amsterdam for generations. The features of the specimen found in The Netherlands fits well with the re-descriptions of this species. The spermatheca figures by Denmark & Muma (1989) and Zannou et al. (2007) show a uniform calyx wall while ours shows the part of calyx towards atrium thicker. The photograph by Ferragut et al. (2010) indicates that feature very well.
