Jiang, Jia, Luo, Gui-Mei & Song, Yue-Hua, 2021, Two new species of the genus Arboridia Zachvatkin from China (Hemiptera: Cicadellidae: Typhlocybinae), Zootaxa 5005 (3), pp. 349-357 : 354-356

Arboridia (Arborifera) changlingensis sp. nov.

( Figs 5–8 , 27–34 )

Description. Vertex white, with two pairs of preapical spots: one pair of oval black spots located near anterior margin; another pair located on both sides of coronal suture ( Figs 5, 7 ). Face white, with a transverse brown-black stripe extended from antennal pits to frontoclypeus, anteclypeus pale ( Figs 6, 8 ). Pronotum mostly dark brown ( Figs 5, 7 ). Scutellum brown, with basal triangles and apex black, a nearly triangular black spot situated between basal triangles ( Figs 5, 7 ). Fore wing mostly grey to black with oblique black bands extended to costal margin ( Figs 5, 6 ).

Male abdominal apodemes slightly extending beyond 3rd sternite ( Fig. 27 ).

Male genitalia. Pygofer dorsal appendage simple, straight in dorsal view, curved downward in lateral view, hook-like apically ( Figs 28, 29 ). Subgenital plate with 2 macrosetae in middle and several fine setae at apex, row of short stout setae from subbase to apex along upper margin ( Figs 28, 30 ). Style long and slender, with 3 points at apex, first two points short, third point elongate, slender and curved; preapical lobe developed ( Fig. 31 ). Aedeagus strongly compressed and broad in lateral view, with two pairs of processes arising from apex and base of shaft respectively, basal processes long and slender, shorter than shaft, truncate at apex, distal processes short and curved ventrad, V-shaped in ventral view; preatrium short; a pair of small triangular flanges arising from dorsal margin of shaft near midlength; gonopore almost apical, on ventral surface ( Figs 32, 33 ). Connective V-shaped, lateral arms long and stem very short ( Fig. 34 ).

Measurement. Male length 3.4 mm (including wing).

Specimen examined. Holotype: ♂, CHINA, Guizhou Prov., Guiyang, Changlingpo Forest Park, 27 VI 2020, coll. Jia Jiang and Xiaowei Yuan.

Remarks. This new species is similar to Arboridia surstyli Cai & Xu, 2006 , but differs in having the aedeagus with pair of small hilly processes on the dorsal side instead of sharp inverted processes ( Figs 32, 33 ), and the central lobe of connective absent ( Fig. 34 ).

Etymology. The new species is named after its type locality: “Changlingpo” Forest Park, Guizhou Province, China.
