Prodorsal shield with frontal lobe, 38 (35–41) long, 67.5 (65– 70) wide; median, admedian and submedian lines complete; shield design with network, each lateral sides with short lines. Scapular tubercles set ahead of rear margin, 27 (25–29) apart; scapular setae ( sc ) 6.5 (6–7), projecting mediad. Coxal area with granules, coxae І sternal line present, coxal seta І ( 1b ) absent, coxal seta І ( 1a ) 4.5 (4–5), coxal seta III ( 2a ) 10 (10–11). Legs segments tibiae fused with tarsi. Legs І 21.5 (20–24), femur 10 (9–11), basiventral femoral setae ( bv ) 7.5 (7–8); genu 3 (3), antaxial genual setae ( l'' ) 25 (23–28); tarsus 7 (7–8); tarsal empodium simple, 4-rayed, tarsal solenidion knobbed. Legs І 21 (19.5–22.5), femur 9 (9–10), basiventral femoral setae ( bv ) 11 (10–12); genu 2.5 (2–3), antaxial genual setae ( l'' ) 10 (9–12); tarsus 7 (7–8). Opisthosoma arc-shaped, dorsal opisthosoma with 52 (50–54) annuli, smooth; ventrally annuli 58 (56–61), with elongated microtubercles. Setae c2 17 (15–18) on ventral annulus 6; setae d 53 (48–56), on ventral annulus 19; setae e 7.5 (6–9), on ventral annulus 32, setae f 15 (13–18), on 7th ventral annulus from rear; Caudal setae ( h2 ) present, accessory setae ( h1 ) absent. Female genitalia 17.5 (15–20) long, 23 (21–25) wide, MALE: Not seen. FIGURE 2. Disella baisensis sp. nov. CGF, coxigenital area of female; D, dorsal aspect of female; E, empodium (enlarged); L1, Legs І; L2, Legs І; LS, lateral view of annuli (enlarged) (scale CGF = 21; D =37; L1, L2 = 15). Types. Holotype , female , Tongling Great Canyon , 12 km East of Jingxi county ( 23°15'N , 106°41'E ), Guangxi Zhuang Autonomous Region , China , 11-Aug.-2004 , from Caesalpinia sp. ( Fabaceae ) , coll. Sui-Gai WEI and De-Wei LI . Paratypes , 16 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 baisensis is derived from the geographic area in which it was collected. Notes. This species is similar to Disella octcella Huang 2001 , but can be differentiated by prodorsal lateral shield design with network and dashes, coxal area with granules, accessory setae ( h1 ) absent ( D. octcella shield sides with short lines, coxal area smooth, accessory setae ( h1 ) present).
