Song, Yue-Hua & Li, Zi-Zhong, 2015, Review of the genus Arboridia Zachvatkin (Hemiptera: Cicadellidae: Typhlocybinae), with description of two new species from China, Zootaxa 3990 (4), pp. 584-592 : 588

Arboridia ochracea Song & Li , sp. nov.

(Figs D–F, 8–15)

Description. Vertex brownish yellow, with pair of milky yellow preapical spots medially. Eyes black (Figs D, E). Face brownish yellow (Fig. F). Pronotum pale yellow, with central part translucent, revealing three large black spots on mesonotum (Fig. D). Scutellum with apex and basal triangles black (Fig. D). Fore wing yellowish white, clavus with continuous dark brown vitta parallel to suture (Figs D, 8).

Male abdominal apodemes small, not surpassing 3rd sternite ( Fig. 9 ).

Male genitalia: Pygofer dorsal appendage simple, shallowly bifurcate at apex ( Fig. 10 ). Subgenital plate without basolateral angulate projection, with 4 macrosetae in oblique row and row of short rigid setae along upper margin; apical 1/3, with dark color ( Fig. 11 ). Style long, with 2 sharp points at apex; preapical lobe small but distinct ( Fig. 12 ). Aedeagus with two pairs of processes arising from apex and base of shaft respectively, basal processes short, slender and closely appressed on ventral surface of shaft, distal processes approximately same length but arising laterad of gonopore and extended posterolaterad; aedeagal shaft long, only median area slightly bent ventrad; gonopore large, apical on ventral surface; preatrium much longer than dorsal apodeme, evenly curved in lateral view ( Figs 13, 14 ). Connective robust, broadly V-shaped ( Fig. 15 ).

Measurement. Body length males 3.2–3.3 mm, females 3.3–3.4 (including wing).

Specimen examined. Holotype: ♂, CHINA, Henan Prov., Mt. Baiyun, 17-VIII-2008, coll. Yuehua Song and Can Li (GUGC). Paratypes: 1♂, 3♀♀ (GUGC); 1♂, 1♀(GZNU), same date as holotype.

Remarks. The new species can be distinguished from other species of the genus by its unique aedeagus, which has two pairs of processes arising from apex and base of aedeagal shaft respectively ( Figs 13, 14 ).

Etymology. The specific name is derived from the Latin word “ ochraceus ”, referring to the fore wing clavus with continuous orange-brown vitta (Fig. D).
