Aculops baligouis sp. nov.

( Fig. 1 )

Description. FEMALE: (n = 6) Body fusiform, 216 (198–220), 50 (48–51) wide, 56 (53–58) thick; light yellow. Gnathosoma 25 (24–27), projecting obliquely down. Prodorsal shield 36 (35–37), 40 (38–41) wide; subtriangular; frontal lobe acuminate; median line present 1/3 at base and connected with admedian lines at basal 1/3, admedian and submedian lines connected and form network. Dorsal tubercles on rear margin, 21 (20–21) apart, scapular setae (sc) 31 (29–33) projecting posterior. Coxal area with granules; anterolateral setae on coxisternum (1b) 6 (6–7), proximal setae on coxisternum (1a) 12 (11–14), proximal setae on coxisternum

(2a) 29 (28–33). Prosternal apodeme present. Legs with usual series of setae. Legs 28 (25–30), femur 8 (8–9), basiventral femoral setae (bv) 10 (10–11); genu 4 (4–5), antaxial genual setae (l'') 20 (18–21); tibia 7 (6–7), paraxial tibial setae (l') 5 (5–6), setae located 1/3 from dorsal base; tarsus 5 (5–6); empodium simple, 4­ rayed, tapered solenidion. Legs 24 (23–25), femur 6 (6–7), basiventral femoral setae (bv) 10 (10–11); genu 3 (3–4), antaxial genual setae (l'') 7 (6–7); tibia 6 (5–6); tarsus 5 (4–5); empodium simple, 4­rayed, tapered solenidion. Opisthosoma: dorsal opisthosoma with 35 (32–38) annuli, with elliptical microtubercles, ventrally with 56 (53–62) annuli, with spiny microtubercles. Setae c2 12 (10–14) on ventral annulus 11 (10–11); setae d 30 (28–33) on ventral annulus 23 (22–24); setae e 20 (18–20) on ventral annulus 38 (38–39), setae f 25 (23–27) on 6th ventral annulus from rear. Setae h1 4 (3–4). Female genitalia 12 (12–13), 20 (20–21) wide, coverflap with 10 longitudinal ridges and 3 transverse lines at base, proximal setae on coxisternum (3a) 15 (14–18).

MALE: (n = 3) 186 (180–195), 38 (37–38) wide; genitalia 5 (5–6), 16 (16­17) wide, proximal setae on coxisternum III (3a) 15 (14–17).

Types. Holotype, female, China: Henan Province, Hui County, Baligou, 35°53.72’N, 113°34.70’E. July 11, 2004, from Acer sp. L. ( Aceraceae ), coll. Xue, Xiao­Feng. Paratypes, 5 females and 3 males, with the same data as holotype.

Relation to host. Vagrant on leaf surface. No damage to the host was observed.

Etymology. The specific designation baligouis is from the place where the host plant and the mite were found, Baligou.

Remarks. This species is similar to Aculops wikstrolmiai Huang, 2001 a, but can be differentiated by dorsal opisthosoma with elliptical microtubercles (with spiny microtubercles and smooth at posterior in A. wikstrolmiai ), coxal area with granules (with short lines in A. wikstrolmiai ), empodium 4­rayed, tapered solenidion (empodium 6­rayed, knobbed solenidion in A. wikstrolmiai ). This species is also similar to A. glabri ( Keifer), 1952 , but can be differentiated by coxal area with short lines (coxal area smooth in A. glabri ), ventral annuli with spiny microtubercles (ventral annuli with round microtubercles in A. glabri ).
