Like Oligonychus tylus, the new species is not monophagous. Oligonychus tylus is known from Panicum maximum, Sorghum and an unidentified wild grass (Poaceae), and also Phoenix dactylifera (Arecaceae) (Baker & Pritchard 1960; Gerson et al., 1983; Sirsikar & Nagabhusanam 1986).Published as part of Zeity, Mahran, Srinivasa, N. & Gowda, C.

Tarsus II with 3 tactile setae and 1 solenidion proximad to duplex setae. Empodial spurs absent. Etymology. The specific epithet is derived from an adjective in Latin " hirsutus " meaning " hairy ", and refers to the hair like projections or processes on the dorsal striae of the female. Type material. Holotype one male, from G. sylvestre, University of Agricultural Sciences, Bangalore, south India (N13o04 ' 35''; E77o34 ' 46''; elevation 934 m), January 2015, coll. Mahran Zeity. Paratypes, 17 males and 10 females, data same as for holotype (AINP 1738). Remarks. The aedeagus of this new species is similar to Tetranychus kanzawai Kishida in having a broad and rounded dorsal margin with slight angulation. The aedeagus differs slightly in having the posterior projection extended and curved distally, whereas this projection is straight in T. kanzawai. Females also differ from T. kanzawai in having broken pregenital striae, whereas they are entire in T. kanzawai. Furthermore, the new species is distinctive from all described species under Tetranychus in having dorsal striae with lobes extended like hairs. Carbonnelle and Hance (2004) found that the shape of dorsal lobes was highly variable in the T. urticae species complex, thus showing it has limited diagnostic power. However, the dorsal lobes of T. hirsutus are so unique that we believe they can be used to distinguish this species from others. The extension of these dorsal lobes increases the total surface area and might play a significant role in temperature and body water regulation, as Jeppson et al. (1975) and Mollet and Sevacherian (1984) have opined. More investigation is required to ascertain the functional significance of these lobes. Biological observations. The new species inhabits the undersurface of leaves of Gymnema sylvestre. The body size of females is relatively large, while that of males is smaller. Both sexes are red in color but females are darker. Females lay orange colored eggs under silken webbing and freshly emerged adult females are ash colored, which develop into dark red females on maturity.Published as part of Zeity, Mahran, Srinivasa, N. & Gowda, C.

Number of tactile setae and solenidia (in parenthesis) on legs I–IV: I 2 – 1 – 10– 5– 9 + (1) – 13 + (1) + 2 duplexes</p> <p>II 2 – 1 – 6 – 5 – 7 – 13 + (1) + 1 duplex</p> <p>III 1 – 1 – 4 – 4 – 6 – 9 + (1)</p> <p>IV 1 – 1 – 4 – 4 – 7 – 10 + (1)</p> <p>Tarsus I with 4 tactile setae proximad to proximal duplex setae and 1 solenidion at level of proximal duplex setae. Tarsus II with 3 tactile setae and 1 solenidion proximad to duplex setae. Empodia I and II with an obvious mediodorsal spur; spur on empodium I stout and 2/3 length of proximoventral hairs; spurs on empodia III and IV absent.</p> <p> <b>Specimens examined.</b> 13 females and 13 males on <i>Bambusa bambos</i>, GKVK, Bangalore, south India, August 2012 coll. Mahran Zeity (AINP1002); 15 females and 17 males on <i>Bambusa bambos</i>, Dharwad, south India, September 2013 coll. Mahran Zeity (AINP1341); Six females and nine males on <i>Bambusa bambos</i>, Mudigere, south India, November 2013, coll. Mahran Zeity (AINP1397).</p> <p> <b>Remarks.</b> This species is similar to <i>Tetranychus bambusicola</i> Ehara, but females are separated by the ratio of the size and length of the tarsus I mediodorsal spur and relative to the proximoventral hairs. Both are larger in <i>T. bambusae</i> (15.2µm/ 22.5µm, ratio 68%), while they are smaller in <i>T. bambusicola</i> Ehara is (4µm/10µm, ratio 30%) (measurements are estimated from Ehara and Tho (1988)). The shape of the aedeagus differs slightly, with <i>T. bambusicola</i> having an angulate posterior tip. Both species, <i>Tetranychus bambusae</i> and <i>T. bambusicola</i>, were grouped by Flechtmann and Knihinicki (2002) in the 8th group of <i>Tetranychus,</i> being those with an obvious dorsomedian spur on at least empodium I. This species is a new record from India.</p>Published as part of <i>Zeity, Mahran, Srinivasa, N. & Gowda, C.
