Figs 5-9 , 29-36 , 37-44

Description.

Dorsum orange, yellow or beige. Eyes black, inner and posterior margins white (Figs 5 , 6 ). Vertex without pair of dark spots, with a white patch each side of midline basally; coronal suture orange yellow (Figs 5 , 7 , 8 ). Face orange yellow. Pronotum with ivory or pale white streaks situated laterad of anterior margin. Scutellum pale or whitish yellow with lateral triangles dark to pale brown (Figs 5 , 7 , 8 ). Forewing with oblique pale reddish-orange vittae in clavus and adjacent area of wing. Abdominal segments milky yellow, tergites with segment margins brown. Subgenital plate with nearly 2/3 apically dark (Figs 5 , 6 ).

Ventral abdominal apodemes small, extended to posterior margin of 3rd sternite (Figs 32 , 43 ).

Male genitalia. Pygofer dorsal appendage claw-like (Figs 29 , 37 ). Subgenital plate with 3 lateral macrosetae in an oblique row slightly basad of midlength (Figs 31 , 38 ). Style slender, with 2 points, heel point small; sword-like apically with transverse wrinkles in lateral view (Figs 30 , 41 ), serrated in ventral view (Fig. 42 ). Aedeagus relatively small, shaft laterally compressed, digitate and slightly upturned in lateral view; subbasally with three processes, two basal processes and a single unpaired spike basad, the distal paired processes divergent with branches slender, the proximal process slightly shorter and more robust, finger-like in ventral view (Figs 34 , 35 , 39 , 40 ); preatrium long. Connective V-shaped (Figs 36 , 44 ).

Measurement.

Body length males 2.7-2.9 mm, females 2.9-3.0 mm.

Specimen examined.

Holotype ♂: China, Guizhou Prov., Jianhe, 26.V.2017, coll. Chang Han and Yaowen Zhang, on kiwi (GUGC). Paratypes: 23♂♂, 25♀♀, same data as holotype on kiwi; 3♂♂, 6♀♀, China, Guizhou Prov., Wujiang, 19.V.2017, coll. Chang Han and Bin Yan, on walnut (GUGC).

Etymology.

The new species name is derived from the Latin words " ruber " (red) and " vittatus " (banded), referring to the reddish-orange oblique stripes on the forewings.

Remarks.

The new species can be distinguished from most Arboridia species by its vertex and pronotum without dark spots (Figs 5 , 7 , 8 ) and reddish-orange stripes on the forewing. Its male genitalia is similar to A. (A.) lunula Song & Li, 2013, but can be distinguished by the sword-like apex of the style and aedeagus with three basal ventral processes, the upper paired processes slender (Figs 34 , 39 ).

Host.

Actinidia chinensis Planch (kiwi fruit); Juglans regia L. (walnut).
