Scapular tubercles on rear margin, 27 (26–28) apart, scapular setae (sc) 7 (6–8) projecting posteriorly. Coxal area with heavily granules and few short lines; anterolateral setae on coxisternum I (1b) 7 (7–8), proximal setae on coxisternum I (1a) 11 (10–12), proximal setae on coxisternum II (2a) 18 (16–20). Prosternal apodeme present. Legs: Leg I 30 (29– 32), femur 8 (8–9), basiventral femoral seta (bv) 13 (10–14); genu 4 (4–5), antaxial genual seta (l'') 22 (21– FIGURE. 3 Indotegolophus bambusae sp. nov.

Types. Holotype, female, from Bambusa sp. ( Gramineae ), Wanluo Mountain, Chizhou City, Anhui Province, China, 30°39'N, 117°31'E, October 4, 2007, coll. by Zi-Wei Song and Zhen Wang. Paratypes, 5 females and 1 male, 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 wanluoensis is from the locality where the host plant and the new species were collected, Wanluo Mountain.

Remarks. This species is similar to A. bambusus Huang, 2001 b, but can be differentiated by prodorsal shield design with incomplete median line and submedian lines (prodorsal shield with complete median and submedian lines in A. bambusus ); dorsal opisthosoma with round microtubercles (dorsal opisthosoma smooth in A. bambusus ); female genital coverflap with cross lines at base (female genital coverflap smooth at base in A. bambusus ).
