CHINA , Yunnan Province : Menglun , 19.v.2012 , coll. Wang Fang , 1 slide, 1 adult ♀ ; Tengchong , 6.v.2012 , coll. Wang Fang , 1 slide, 2 adult ♀♀ ; Mengla , 21.v.2012 , on Cycas revoluta (Cycadaceae), coll. Wang Fang , 1 slide, 1 adult ♀ . Diagnosis (based on observed specimens, and descriptions and illustrations by Hamon & Williams (1984) and Tang (1991)) . Adult female body very elongate and extremely narrow, 2.5–5.5 mm long, 1.0–2.0 mm wide, fresh insects creamy-white to yellowish green, older females reddish brown to black. Dorsum with derm strongly sclerotized in older females, with small round or oval clear areas (areolations) present; dorsal setae robust, spine like and slightly tapering with pointed or bluntly rounded apices; tubular ducts absent; submarginal tubercles numbering 8– 19 around dorsum; preopercular pores numbering 8–13, situated anterior to anal plates; anal plates each triangular, together quadrate, posterolateral margin slightly longer than anterolateral margin, bearing 1 subdiscal seta, 3 apical setae; anogenital fold with 2 pairs of anterior margin setae, and 2 pairs of lateral marginal setae. Margin with marginal setae slender with pointed apices; each stigmatic cleft containing 3 spines, median spine 3–4 times as long as a lateral spine, both cylindrical with bluntly rounded apices. Venter with antennae reduced, each with 3 segments, occasionally 5; 2 pairs of inter-antennal setae present; submarginal setae present; long pregenital setae numbering 3 pairs; legs reduced, tibio-tarsal articulations fused; claw digitules unequal, with 1 thick and 1 thin; multilocular disc pores each primarily with 7 loculi, occasionally with 5–8 loculi, present around genital area and on preceding 2 or 3 abdominal segments; and ventral tubular ducts absent. Host plants. Recorded from members of 42 genera belonging to 29 families (García-Morales et al . 2016). For Chinese records, Mangifera indica (Anacardiaceae) , Syzygium jambos (Myrtaceae) ( Tang 1991 ) and Cycas revoluta (Cycadaceae) . Distribution.
