( Fig. 4 ) Female : (n = 12) 160 long, 45 wide, 40 thick; light yellow in color. Gnathosoma 15, projecting obliquely down. Prodorsal shield 38 long, 38 wide; prodorsal shield with frontal lobe; median, admedian and submedian lines present, admedian and submedian lines connected and forms network. Dorsal tubercles on rear shield margin, 24 apart, scapular setae ( sc ) 7 projecting posteriorly. Sternal line present. Coxal area with short lines; anterolateral setae on coxisternum I ( 1b ) 5, proximal setae on coxisternum I ( 1a ) 12, proximal setae on coxisternum II ( 2a ) 30. Legs I 30 long, femur 9, basiventral femoral setae ( bv ) 10; genu 5 long, antaxial genual setae ( l'' ) 18 long; tibia 7, paraxial tibial setae ( l' ) 6, setae located 1/3 from dorsal base; tarsus 6 long; tarsal empodium simple, 7­rayed, tarsal solenidion tapered. Legs II 28 long, femur 8, basiventral femoral setae ( bv ) 6; genu 4 long, antaxial genual setae ( l'' ) 5 long; tibia 6; tarsus 6 long; tarsal empodium simple, 7­ rayed, tarsal solenidion tapered. Dorsal opisthosoma with 28 annuli, with obscure spiny microtubercles on rear annular margins, ventrally with 54 microtuberculate annuli. Setae c2 20 on ventral annulus 9; setae d 38 on ventral annulus 22; setae e 10 on ventral annulus 38; setae f 15 on 5th ventral annulus from rear. Setae h1 4 long. Female genitalia 13 long, 18 wide, coverflap with 10 longitudinal ridges, proximal setae on coxisternum III ( 3a ) 10 long. FIGURE 4. Tetra formosae n. sp. A, dorsal view of female; B, coxae and female genitalia; C, legs I and II; D, lateral microtubercles; E, empodium; F, male genitalia. Male : (n = 2) 150 long, 38 wide; genitalia 5 long, 15 wide, proximal setae on coxisternum III ( 3a ) 15 long. Type data : Holotype , female, from Lespedeza formosa (Vog.) Koehne (Leguminosae) , Baotianman, Neixiang County, Henan Province, P.R. China , 23 July 2004 , coll. X.­F. Xue. Paratypes , 11 females and 2 males , 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, formosa . Note : This species is similar to Tetra shiheziensis Wang & Lu, 2004 , but can be differentiated by the prodorsal shield with complete median line, empodium 7­rayed, solenidion tapered and dorsal annuli with spiny microtubercles.
