( Fig. 12 View Figure )

Description. FEMALE: (n = 12) Body fusiform, 342 (340–347), 111 (105–111) wide, 105 (103–110) thick; light yellow. Gnathosoma 90 (87–90), projecting downwards, pedipalp coxal setae (ep) 5 (5–6), dorsal pedipalp genual setae (d) 12 (11–12), chelicerae 82 (80–83). Prodorsal shield 37 (37–39), 80 (79–80) wide; prodorsal shield design with incomplete median and submedian lines, complete admedian lines; median, admedian and submedian lines connected and forming network. Scapular setae (sc) and tubercles absent. Coxal area with short lines and granules; anterolateral setae on coxisternum I (1 b) absent, proximal setae on coxisternum I (1 a) 40 (35–40), proximal setae on coxisternum II (2 a) 70 (68–71). Prosternal apodeme present. Legs: Leg I 53 (52–55) long, femur 24 (22–24), basiventral femoral seta (bv) absent; genu absent; tibia 10 (8–10), paraxial tibial seta absent; tarsus 12 (12–13), tarsal seta (u') 5 (5–6), tarsal empodium divided, each 8 -rayed, tarsal solenidion knobbed. Leg II 51 (48–51), femur 20 (19–21), basiventral femoral seta (bv) absent; genu absent; tibia 9 (8–9); tarsus 12 (12–13), tarsal seta (u') 5 (5–6), tarsal empodium divided, each 8 - rayed, tarsal solenidion knobbed. Opisthosoma: dorsal opisthosoma with 64 (62–65), smooth, with three dorsal ridges, middorsal ridge extend almost the length of the opisthosoma, subdorsal ridges which extend from 9 th dorsal annulus fade at 2 / 3 from anterior; ventrally with 86 (85–87) annuli, with nail-shape microtubercles. Setae c 2 absent; setae d 15 (12–15) on ventral annulus 34 (33–35); setae e 12 (10–12) on ventral annulus 55 (54–56); setae f 46 (46–48) on 11 th ventral annulus from rear. Setae h 1 minute. Female genitalia 25 (23–25), 33 (31–33) wide, coverflap with granules, proximal setae on coxisternum III (3 a) 8 (7–8).

MALE: Unknown.

Types. Holotype, female, from Buxus  sp. ( Buxaceae  ), Dangchang County, Gansu Province, China, 33 ° 57 ' 39 N, 104 ° 19 ' 45 E, September 13, 2005, collected by Zi-Wei Song and Xiao-Feng Xue. Paratypes, 11 females, with the same data as holotype.

Relation to host. Mites are vagrant on the undersurface of leaves, causing no apparent damage.

Etymology. The specific designation buxusis  is from the generic name of the host plant, Buxus  .

Remarks. This species is similar to Diptilomiopus octogonus Huang, 2001  , but can be differentiated by ventral annuli with nail microtubercles on annular rear margins (ventral annuli with round microtubercles in D. octogonus  ), dorsal opisthosoma with obvious median ridge and two subdorsal ridges (dorsal opisthosoma with only one faint median ridge in D. octogonus  ), coxal area with short lines and granules (coxal area with only granules in D. octogonus  ).
