Tetra suspensae  n. sp. ( Fig. 1View FIGURE 1)

Female: (n = 6) Body fusiform, 198 long, 60 wide, 65 thick; light yellow in color. Gnathosoma 20, projecting obliquely down. Prodorsal shield 50 long, 58 wide; prodorsal shield with frontal lobe; median line present 1 / 3 at base, median and admedian lines connected by transverse line at basal 1 / 3, admedian and submedian lines connected by transverse line at basal 2 / 3. Dorsal tubercles on rear shield margin, 30 apart, scapular setae (sc) 7 projecting posteriorly. Sternal line present. Coxal area with granules; anterolateral setae on coxisternum I (1 b) 7, proximal setae on coxisternum I (1 a) 15, proximal setae on coxisternum II (2 a) 28. Legs I 30 long, femur 10, basiventral femoral setae (bv) 10; genu 5 long, antaxial genual setae (l'') 20 long; tibia 6, paraxial tibial setae (l') 4, setae located 1 / 3 from dorsal base; tarsus 5 long; tarsal empodium simple, 4 ­rayed, tarsal solenidion knobbed. Legs II 28 long, femur 8, basiventral femoral setae (bv) 10; genu 4 long, antaxial genual setae (l'') 6 long; tibia 6; tarsus 5 long; tarsal empodium simple, 4 ­rayed, tarsal solenidion knobbed. Dorsal opisthosoma with 22 annuli, with spiny microtubercles on rear annular margins, ventrally with 55 microtuberculate annuli. Setae c 2 15 on ventral annulus 12; setae d 35 on ventral annulus 24; setae e 20 on ventral annulus 40; setae f 22 on 5 th ventral annulus from rear. Setae h 1 3 long. Female genitalia 15 long, 22 wide, coverflap with 10 longitudinal ridges, proximal setae on coxisternum III (3 a) 15 long.

Male: (n = 1) 165 long, 45 wide; genitalia 5 long, 18 wide, proximal setae on coxisternum III (3 a) 10 long.

Type date: Holotype, female, from Forsythia suspensa (Thunb.) Vahl (Compositae)  , Tianchishan mountain, Song County, Henan Province, P.R. China, 13 July 2004, coll. X.­ F. Xue. Paratypes, 5 females and 1 male, with the same data as holotype.

Relation to host: Vagrant on leaf surface. No damage to the host was observed. Etymology: Derived from the specific epithet of the type host plant, suspensa  . Note: This species is similar to Tetra forsythiae Boczek, 1961  , but can be differentiated by the shield design with median and submedian lines, dorsal annuli with spiny microtubercles and coxal area with granules.
