Description

FEMALE: (n = 5) Body fusiform, 230 (223–232) long, 80 (78–83) wide, 73 (71–75) thick; light yellow. Gnathosoma 20 (19–21), projecting obliquely down. Prodorsal shield 43 (41–44) long, 68 (65–70) wide; subtriangular; frontal lobe broad; median, admedian and submedian lines present. Scapular tubercles on rear margin, 32 (31–32) apart, scapular setae (sc) 13 (11–15) projecting posterior. Coxal area with short lines; anterolateral setae on coxisternum (1 b) 6 (6–7), proximal setae on coxisternum (1 a) 25 (22–27), proximal setae on coxisternum (2 a) 32 (30–34). Prosternal apodeme present. Legs with usual series of setae. Legs 33 (31–35), femur 9 (9–10), basiventral femoral setae (bv) 8 (8–9); genu 5 (4–5), antaxial genual setae (l'') 20 (18–21); tibia 9 (8–9), paraxial tibial setae (l') 4 (4–5), setae located 1 / 3 from dorsal base; tarsus 6 (5–6); tarsal empodium simple, 4 ­rayed, tarsal solenidion slightly knobbed. Legs 29 (27–31), femur 8 (7–8), basiventral femoral setae (bv) 9 (8–10); genu 4 (4–5), antaxial genual setae (l'') 6 (5–7); tibia 7 (6–7); tarsus 6 (5–6); tarsal empodium simple, 4 ­rayed, tarsal solenidion slightly knobbed. Opisthosoma: dorsal opisthosoma with 29 (27–31) annuli, with filament microtubercles, ventrally with 42 (40–45) microtuberculate annuli. Setae c 2 18 (16–19) on ventral annulus 7 (7–8); setae d 50 (45–52) on ventral annulus 15 (14–16); setae e 17 (15–18) on ventral annulus 25 (24–26), setae f 26 (24–28) on 5 th ventral annulus from rear. Setae h 1 3 (2–3). Female genitalia 15 (14–15) long, 24 (23–24) wide, coverflap with 6 longitudinal ridges, proximal setae on coxisternum (3 a) 24 (22–25).

MALE: (n = 6) 178 (175–181) long, 65 (63–66) wide; genitalia 5 (5–6), 20 (19–22) wide, proximal setae on coxisternum III (3 a) 11 (10–13).

Types

Holotype, female, China  : Shaanxi Province, Mei County, Taibai Mountain, 34 °01.51’N, 107 °48.36’E. September 1, 2004, from Crataegus pinnatifida Bunge  ( Rosaceae  ), coll. Xue, Xiao­Feng & Song, Zi­Wei. Paratypes, 4 females and 6 males, with the same data as holotype.

Relation to host

Mites are vagrant on leaf surface, causing no apparent damage.

Remarks

This species is similar to Tetra intermedia Huang, 2001  , but can be differentiated by opisthosoma with filament microtubercles on dorsal annuli (smooth in T. intermedia  ), coxal area with short lines (smooth in T. intermedia  ), setae h 1 present (absent in T. intermedia  ) and paraxial tibial setae (l') present (absent in T. intermedia  ).
