Description

FEMALE: (n = 6) Body fusiform, 200 (195–207) long, 55 (53–57) wide, 58 (55–61) thick; light yellow. Gnathosoma 21 (20–23), projecting obliquely down. Prodorsal shield 37 (36–38) long, 45 (43–47) wide; subtriangular; frontal lobe present; median, admedian and submedian lines present and connected. Scapular tubercles near rear margin, 30 (29–32) apart, scapular setae (sc) 27 (25–30) projecting posterior. Coxal area with short lines; anterolateral setae on coxisternum (1 b) 8 (7–9), proximal setae on coxisternum (1 a) 20 (19–22), proximal setae on coxisternum (2 a) 32 (30–35). Prosternal apodeme present. Legs with usual series of setae. Legs 31 (29–33), femur 9 (8–9), basiventral femoral setae (bv) 10 (9–11); genu 5 (5–6), antaxial genual setae (l'') 18 (17–19); tibia 9 (8–9), paraxial tibial setae (l') 6 (5–7), setae located 1 / 3 from dorsal base; tarsus 6 (5–6); tarsal empodium simple, 6 ­rayed, tarsal solenidion knobbed. Legs 25 (23–27), femur 7 (6–8), basiventral femoral setae (bv) 10 (10–11); genu 5 (4–5), antaxial genual setae (l'') 9 (8–10); tibia 6 (5–6); tarsus 5 (5–6); tarsal empodium simple, 6 ­rayed, tarsal solenidion knobbed. Opisthosoma: dorsal opisthosoma with 31 (29–32) annuli, with elliptical microtubercles, ventrally with 67 (65–70) microtuberculate annuli. Setae c 2 16 (13–18) on ventral annulus 12 (11–12); setae d 40 (35–44) on ventral annulus 24 (22–24); setae e 27 (23–30) on ventral annulus 43 (41–44), setae f 30 (28–32) on 6 th ventral annulus from rear. Setae h 1 4 (3–4). Female genitalia 13 (13–14) long, 20 (19–22) wide, coverflap with 8 longitudinal ridges and 3 transverse lines at base, proximal setae on coxisternum (3 a) 21 (19­23).

MALE: (n = 1) 163 long, 48 wide; genitalia 5, 16 wide, proximal setae on coxisternum III (3 a) 23.

Types

Holotype, female, China  : Shaanxi Province, Cuihua Mountain, 32 °59.40’N, 109 °00.04’E. August 14, 2005, from Salix babylonica  L. ( Salicaceae  ), coll. Xue, Xiao­ Feng & Song, Zi­Wei. Paratypes, 5 females and 1 male, with the same data as holotype.

Relation to host

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

Etymology

The specific designation salixis  is from the genetic name of host plant, Salix  .

Remarks

This species is similar to Tetra guiyangensis Kuang & Hong, 1989  , but can be differentiated by empodium 6 ­rayed (empodium 4 ­rayed in T. guiyangensis  ), dorsal annuli with elliptical microtubercles on rear annular margins (dorsal annuli smooth in T. guiyangensis  ) and with different shield designs.
