Paratypes: eight females, same data as holotype; four females, Tehran, Karaj, 36 °04'N, 51 ° 19 'E, alt. 2200 m, 28 July 2009, O. Joharchi coll., on Polyphylla olivieri   (in JAZM and ANIC).

Description. Female. Dorsal idiosoma. Dorsal shield length 860–966 µm, width at level of r 3 504–546 µm (n = 4) ( Fig. 32 View FIGURES 32 – 40 ). Dorsal shield oval, narrower posteriorly, with weak postero-lateral reticulation, with 39 pairs of long setae, 22 pairs on podonotal section plus r 6 outside the shield, and 17 pairs on opisthonotal section, including two pairs of Zx setae between J and Z setae. Seta Z 4 longest (240–265 µm), s 3, s 4, s 5 (210–218 µm) and j 3 (170–180 µm) also long, j 6 long enough to reach to J 1, J 1 long enough to reach J 2 but not to J 3, J 4 not long enough to reach J 5. Soft skin surrounding shield with ten pairs of setae.

Ventral idiosoma ( Fig. 33 View FIGURES 32 – 40 ). Tritosternum with paired pilose laciniae, pre-sternal area weakly sclerotised. Sternal shield with straight anterior margin and slightly concave posterior margin, with three pairs of smooth sternal setae, one pair of lyrifissures adjacent to setae st 1, and a pair of circular pores between st 2 and st 3, anterior and antero-lateral surface of sternal shield with polygonal ornamentation, central and posterior are smooth. Metasternal platelets absent, metasternal setae st 4 and metasternal pores located in soft skin; endopodal plates II/III completely fused to sternal shield, endopodal plates III/IV elongate, narrow, curved. Genital shield tongue-shaped, length 327– 332 µm, maximum width 143–168 µm, posterior edge rounded, surface with polygonal ornamentation, bearing the genital setae st 5. Paragenital pores located on soft skin close to seta st 5. Anal shield triangular, its anterior half with lineate ornamentation, unpaired post-anal seta shorter than para-anal setae, cribrum large, anal pores located on minute platelets outside anal shield. Opisthogastric skin striated, with one pair of oval metapodal plates and 11 pairs of smooth setae, ZV 5 and JV 5 very long and wavy. Exopodal plates behind coxa IV small and narrow. Peritrematal shield free, peritreme extending from coxa IV to posterior level of coxa I, post-stigmatal section conspicuous and narrow, with one pair of pores.

Gnathosoma   . Epistome irregularly denticulate laterally, with smooth apical section ( Fig. 34 View FIGURES 32 – 40 ). Hypostomal groove with six rows of denticles, each with about ten small teeth, and a smooth anterior transverse line. Hypostome with four pairs of smooth pointed setae, internal posterior hypostomal setae h 3 longest ( Fig. 35 View FIGURES 32 – 40 ), corniculi robust and horn-like, reaching mid-level of palp femur. Palp chaetotaxy: trochanter 2, femur 5, genu 6, tibia 12, tarsus 15, genu with a distinct dorso-distal triangular condyle, all setae smooth and needle-like, palp tarsal claw twotined. Fixed digit of chelicera with a small basal triangular tooth about ten smaller teeth, and a larger median tooth ( Fig. 36 View FIGURES 32 – 40 ), pilus dentilis short and robust, dorsal seta long, thick, prostrate, movable digit with two large teeth, arthrodial membrane with a rounded flap and a few short filaments.

Legs. Legs II and III short, and leg IV longest. Chaetotaxy: Leg I: coxa 0 0/ 1 0/ 1 0, trochanter 1 1 / 1 0/ 2 1, femur 2 3 / 1 2 / 3 2, genu 2 3 / 2 3 / 1 2, tibia 2 3 / 2 3 / 1 2. Leg II: coxa 0 0/ 1 0/ 1 0, trochanter 1 0/ 1 0/ 2 1, femur 2 3 / 1 2 / 2 1 (pd 1 longest), genu 2 3 / 1 2 / 1 2 (pd 1 and pd 2 longest), tibia 2 2 / 1 2 / 1 2. Leg III: coxa 0 0/ 1 0/ 1 0, trochanter 1 1 / 1 0/ 1 1, femur 1 2 / 1 1 /0 1 (ad 1 a macroseta), genu 2 2 / 1 2 / 1 1 (ventral setae all thick, pd 1, ad 1 longest), tibia: 2 1 / 1 2 / 1 1 (pl and ventral setae thick). Leg IV: coxa 0 0/ 1 0/0 0, trochanter 1 1 / 1 0/ 1 1, femur 1 2 / 1 1 /0 1 (macroseta ad 1 342–350 µm, ad 2 84–85 µm, Fig. 38 View FIGURES 32 – 40 ), genu 2 2 / 1 3 /0 1 (macrosetae ad 1 163–172 µm, pd 1 152–155 µm, Fig. 39 View FIGURES 32 – 40 ), tibia 2 1 / 1 3 / 1 2 (pl 1 and ventral setae thick), tarsi I –IV with 18 setae 3 3 / 2 3 / 2 3 + mv, md, tarsus II with al 1, pl 1 and all ventral setae thick ( Fig. 37 View FIGURES 32 – 40 ), tarsus IV with four macrosetae ad 2 (210–230 µm), pd 2 (210–230 µm), ad 3 (210–222 µm), pd 3 (184–185 µm) ( Fig. 40 View FIGURES 32 – 40 ). All pre-tarsi with a pair of claws and a long thin membranous ambulacrum.

Insemination structures: Insemination ducts opening on posterior margin of coxa III, sacculus indistinct, apparently unsclerotised.

Etymology. This species is named in honour of Maryam Moradi, who supported this project in many ways. Notes. Hypoaspis maryamae   differs from almost all other species in the genus by the presence of four long macrosetae on tarsus IV and two macrosetae on genu IV. Only H. integer   has two macrosetae on genu IV; H. maryamae   differs from H. integer   by its longer sternal setae and the very long and wavy form of ZV 5. It also differs from H. (H.) polyphyllae   by its longer setae in the central area of the dorsal shield, especially j 6, J 1 and J 2, and by having a greater number of opisthogastric setae.
