Leg II 20–26, femur 8–9, genu 4– 5, tibia 4–5, tarsus 5–7, ω 5–6 distally rounded, empodium simple, 5–7, 6-rayed; femoral setae bv 7–8, genual setae l" 9–13, tarsal setae ft' 6–9, ft " 15–20, u' 3–3.5. Coxae mainly smooth with few dashes on coxae I; setae 1b 7–9, tubercles 1b 9–10 apart, setae 1a 15–21, tubercles 1a 6–8 apart, setae 2a 24–29, tubercles 2a 20–21 apart. Prosternal apodeme 7–8. Opisthosoma with 65–71 dorsal semiannuli, 60–63 ventral semiannuli (counted from first complete annulus after coxae II); 3–5 semiannuli between coxae and genital coverflap plus 2–3 transversal rows of lined granules at the base of the coverflap. Microtubercles: circular on posterior part of dorsal and ventral semiannuli; spiny on the rear margin of the last 3 dorsal semiannuli and elongated and linear on last 5 ventral semiannuli. Setae c2 26–28 on ventral semiannulus 7–9, setae d 30–40 on ventral semiannulus 17– 21; setae e 10–18 on ventral semiannulus 30–36; setae f 13–17 on ventral semiannulus 55–58; 5 annuli posterior to setae f. Setae h2 36–44 apically very fine, h1 absent. Genital coverflap 10–13, 18–20 wide, ornamented with 11–12 striae; setae 3a 11–14, 13–14 apart.

Body 168–190, 50–52 wide, 49 thick; palp genual setae d 3–4; prodorsal shield 27, 36–37 wide, lateral ocellar-like structures 6 diameter; setae sc 7–10, 19–20 apart. Opisthosoma with 64–69 dorsal semiannuli and 57–60 ventral semiannuli (counted from first complete annulus after coxae II); 4 semiannuli between coxae and genitalia. Setae: 1b 6–7, 1a 16–21, 2a 24–30, c2 19–20, d 31–33, e 10–11, f 14– 16, h2 35–48). Male genitalia 17–21 wide, setae 3a 8–12, 17 apart.

Nymph (n = 3) – Body wormlike, 149–154 (excluding gnathosoma), 36–37 wide, 43 thick; palp genual setae d 2; prodorsal shield 23–28, 30 wide; setae sc 6–7, 17 apart. Opisthosoma with 51–59 dorsal semiannuli, 48–51 ventral semiannuli (counted from first complete annulus after coxae II). Setae: 1b 4–7, 1a 13–15, 2a 17–20, c2 10–15, d 19–24, e 6–8, f 9–12, h2 22–25). Setae 3a 3.5–7, 7 apart on semiannulus 10 after coxae.

Type data Buxus sempervirens L. ( Buxaceae ); Halle am Saale, Sachsen, Germany.

Relation to the host plant

Leaf deformation, flower blasting; hairy bud gall-making (2–4 mm diameter); shortening of internodes ( Nalepa 1930; Baker et al. 1996; Soika and Labanowski 1999).

Localities and host plant

30 females, 5 males and 7 nymphs collected during March and July from Buxus sempervirens hyrcana (Pojark.) Takht. (Buxaceae) in Cheshmeh Bolbol, Bander Gaz, Golestan province, Iran .

Previous provincial records for Iran This is the first report of this mite from Iran.

Remarks

Iranian female characters largely matches the short original description and summarized drawings made by Keifer ( Baker et al. 1996). However, the Iranian specimens are longer [182–205 versus 170 in Baker et al. (1996)] and their coxae are mainly smooth with few dashes on coxae I, while according to Baker et al. (1996) coxae ornamented with few curved lines, lines, dashes and lines of granules. In addition the Iranian specimens have shorter seta d (30–40) than Nalepa described specimens with 56 long setae d.
