17 (15–19), J2 18 (16–19), J5 10 (9–11), z2 40 (37–42), z4 45 (42–50), z5 16 (15–18), Z1 19 (18–21), Z4 64 (61–68), Z5 79 (75– 83), s4 63 (60–67), S2 50 (49–52), S4 24 (22–27), S5 16 (13–20), r3 40 (38–43), and R1 32 (30–34).

Peritreme — Long, extending to level setae j1.

Venter — Distances between st1–st1 59 (58–61), st2–st2 71 (70–72), st3–st3 81 (78–84), st1–st3 66 (65–69), st4–st4 77 (75–80), st5–st5 65 (60–70). Ventrianal shield reticulated with three pairs of pre-anal setae (JV1, JV2, and ZV2), and with a pair of small solenostomes gv (3) [distance gv3–gv3 38 (35–42)]. Length of ventrianal shield 125 (118–132), width at level of

ZV2 100 (94–106), width at level of anus 80 (75–85). Setae JV5 66 (63–70).

Chelicera — Fixed digit 32 (32–34) long with three teeth and pilus dentilis ; movable digit

31 (30–32) long with one tooth.

Spermatheca — As described by Döker et al. (2019), 21 (19–23) in length.

Legs — Measurements of macrosetae on leg IV as follows: SgeIV 50 (46–55), StiIV 36 (32–42) and StIV 74 (71–77).

Remarks — This is the second international record of this species. Morphological characteristics of the Syrian specimens are very close to those in the original description ( Döker et al. 2019). A single female of this species has been previously collected from

Syria in 2013 and has been identified as Graminaseius graminis (Chant) ( Barbar 2013) . This misidentification was due to the lack of enough specimens to check. According to the paper of Döker et al. (2019), G. recebi could be differentiated from G. graminis by having several longer dorsal setae (i.e. j4, j5, j6, J2, z2, z4, z5, Z1, S2, and S4) and more teeth on fixed digit (four teeth). Consequently, all the specimens collected from Syria are G. recebi , even if the maximum and /or the minimum lengths of setae mentioned above are slightly out of the range of setae given in the original description of G. recebi ( Döker et al. 2019) and fewer teeth on fixed digit (three teeth in Syrian specimens vs. four teeth in G. recebi ).
