Gnathosoma— 41 (38–45), abruptly curved downward; dorsal pedipalp genual setae (d) 10 (8–13), pedipalp coxal setae (ep) 5 (4–6), palp tarsal ventral setae (v) 5 (5–6); cheliceral stylets 45 (43–49). Prodorsal shield— 53 (51–56), 70 (68–72) wide, frontal lobe long and thin, bent at right angle; median line forked forming Y-shape, admedian and submedian lines incomplete. Scapular tubercles set ahead of rear shield margin, 24 apart, scapular setae (sc) 2 (2–3), directed mediad. Coxisternal plates— Prosternal apodeme present, coxisternal plates І and ІІ sculptured with lines; anterolateral setae on coxisternum І (1b) 14 (12–17), 13 (12–13) apart; proximal setae on coxisternum І (1a) 23 (20–27), 8 (7–8) apart; proximal setae on coxisternum ІІ (2a) 66 (60–70), 27 (27–28) apart. Coxal-genital annuli 8. Legs— Segments normal. Legs І 40 (39–44), trochanter 2 (2–3), femur 14 (13– 14), basiventral femoral setae (bv) absent; genu 5 (5–6), antaxial genual setae (l'') 43 (35–50); tibia 12 (12– 13), paraxial tibial setae (l ʹ) located laterally apical, 17 (15–18); tarsus 7 (7–8), paraxial fastigial tarsal setae (ft') 35 (31–38), antaxial fastigial tarsal setae (ft'') 30 (27–34), paraxial unguinal tarsal setae (u') 10 (9–10); tarsal empodium (ω) broad and entire, 10 (10–11), 8-rayed, tarsal solenidion 9 (9–10), knobbed. Legs ІІ 37 (35–41), trochanter 2 (2–3), femur 14 (13–14), basiventral femoral setae (bv) 7 (7–8); genu 5 (5–6), antaxial genual setae (l'') absent; tibia 9 (8–9); tarsus 7 (7–8), paraxial fastigial tarsal setae (ft') 33 (30–37), antaxial fastigial tarsal setae (ft'') 10 (9–13), paraxial unguinal tarsal setae (u') 10 (9–10); tarsal empodium (ω) broad and entire, 10 (10–11), 8-rayed, tarsal solenidion 9 (9–10), knobbed. Opisthosoma— Dorsum with median broad furrow, dorsal annuli 20, with filamentous microtubercles on rear annular margin; ventral annuli 77 (76–79), with rounded microtubercles on rear annular margin; setae c2 23 (20–25), on 13–14th ventral annulus; setae d 71 (65–75), 33 (32–34) apart, on 28–30th ventral annulus; setae e 22 (20–25), 16 (15–18) apart, on 54-56th ventral annulus; setae f 39 (35–43), 23 (22–24) apart, on 5th ventral annulus from rear; setae h1 absent, setae h2 81 (75–85). Female genital coverflap— 17 (16–18), 32 (32–33) wide, sculptured with basal 12 longitudinal ridges, proximal setae on coxisternum ІІІ (3a) 15 (13–19), 13 (12–15) apart.
Male (n = 1) Body 161, 65 wide. Prodorsal shield— 50, 67 wide, anterior lobe long and thin, bent at right angle; median line forked forming Y-shape, admedian and submedian lines incomplete. Scapular tubercles set ahead of rear shield margin, 24 (23–25) apart. Legs— Segments normal. Legs І basiventral femoral setae (bv) absent; antaxial genual setae (l'') present; paraxial tibial setae (l ʹ) located laterally and apically; tarsal empodium (ω) entire, 8-rayed, tarsal solenidion knobbed. Legs ІІ basiventral femoral setae (bv) present; antaxial genual setae (l'') absent; tarsal empodium (ω) broad and entire, 8-rayed, tarsal solenidion knobbed. Opisthosoma— Dorsum with median broad furrow, dorsal annuli 20, with filamentous microtubercles on rear annular margin; ventral annuli 76, with rounded microtubercles on rear annular margin; setae h1 absent. Male genitalia— 28 wide, proximal setae on coxisternum ІІІ (3a) 12, 12 apart.
Type data. Holotype female, Bubeng village, Mengla county (21°30’N, 101°28’E), Yunnan, China, 26- Nov.-2007, from Dendrocalamus latiflorus Munro (Poaceae), collected by Guo-Quan Wang. Paratypes, 7 females and 1 male, were mounted on 8 slides, with the same data as holotype.
Relation to host. The mites are vagrants on the leaf undersurfaces, no visible damage seen.
Etymology. The specific designation is derived from the generic name of the type host plant.
Remarks. The new species is separated from the other two species of the genus, N. bambusae Kuang & Hong, 1990, and N. guangxiensis Wei & Xie, 2009, by the anterior shield lobe long and thin, bent at a right angle and the dorsal annuli with filamentous microtubercles. In N. bambusae and N. guangxiensis, the anterior shield lobe is blunt and the dorsal annuli are smooth (Kuang & Hong 1990; Wei et al. 2009b).
