Figs 1-4 , 14-20 , 21-28

Description.

Dorsum yellowish brown; eyes grey with posterior margin beige; vertex with a pair of black spots subapically; coronal suture indistinct distally, pale brown basally (Figs 1-3 ). Face yellowish brown with median area of frontoclypeus and anteclypeus brighter towards apex; lorum and gena whitish (Fig. 4 ). Pronotum yellowish brown with brownish spots at anterior margin. Scutellum yellow with lateral triangles dark brown (Fig. 3 ). Forewing hyaline, veins brown. Abdominal tergites black; sternites milky white; subgenital plate dark apically (Figs 2 , 14 ).

Ventral abdominal apodemes small, extended to 4th sternite (Figs 18 , 27 ).

Male genitalia. Pygofer dorsal appendage simple, slender and wavy, with the apex obliquely truncate (Figs 14 , 21 ). Subgenital plate with 3 lateral macrosetae in an oblique row slightly basad of midlength laterally (Figs 15 , 16 , 22 , 23 ). Style long and slender, apex with 3 points; preapical lobe well developed; several small tubercles subapically and at midlength (Figs 20 , 26 ). Aedeagal shaft long and stout, slightly laterally compressed, a pair of long slender basal processes on ventral surface of the shaft, parallel to the shaft in their basal half, then sharply turned in proximal direction in their distal half (Figs 17 , 19 , 24 , 25 ); dorsal apodeme short and robust, expanded laterally at apex; preatrium short (Figs 17 , 24 ). Connective U-shaped, with lateral arms long and stem broad (Figs 19 , 28 ).

Measurement.

Body length males 3.0-3.2 mm, females 3.2-3.3 mm.

Specimen examined.

Holotype ♂: China, Guizhou Prov., Dejiang, 22.VII.2017, coll. Chang Han and Bin Yan, on grape (GUGC). Paratypes: 5♂♂, 5♀♀, same data as holotype.

Etymology.

The new species is named from the Latin word " furcatus ", referring to the forked aedeagal process.

Remarks.

The new species is similar to Arboridia (A.) anteoculara Song & Li, 2013, but differs in only having a pair of processes on the ventrobasal surface of aedeagal shaft (Figs 17 , 24 ); the latter species having two pairs of processes and arising from both sides of the aedeagal shaft.

Host.

Vitis vinifera L. (grape).
