Some new species and new record of the genus Arboridia Zachvatkin (Hemiptera: Cicadellidae: Typhlocybinae) from six provinces of China Author Song, Yue-Hua Author Li, Zi-Zhong text Zootaxa 2013 3613 3 229 244 journal article 10.11646/zootaxa.3613.3.2 4b188f10-8f29-4218-aeb9-b27f491b0403 1175-5326 222347 8657AF12-4839-4C95-87A4-42287F86EFF4 Arboridia Zachvatkin, 1946 Arboridia Zachvatkin, 1946: 153 Type species: Typhlocyba parvula Boheman, 1845 Khoduma Dworakowska, 1972: 403 Type species: Khoduma jacobii Dworakowska, 1972 Description . Dorsum yellow, brown, white or reddish. Color pattern orange, red or brown. Head narrower than pronotum. Crown fore margin weakly produced, broadly rounded apically. Vertex usually with pair of dark preapical spots. Anteclypeus pale, concolorous with rest of face or dark. Pronotum pale or with dark medial vitta or almost entirely dark. Scutellum with lateral triangles dark; apex dark or concolorous with rest of scutellum. Fore wing with or without oblique vittae or with dark spots. Abdominal apodemes small, extended dorsomesad or large, extended beyond posterior margin of 3rd sternite. Male genitalia : Pygofer lobe broad and rounded, usually with sparse long fine setae and microtrichia well developed. Pygofer dorsal appendage movably articulated, ventral appendages absent. Subgenital plate with lateral margin distinctly widened subbasally, apex pocket-like, with 2–4 subbasal macrosetae on outer margin. Style apex usually with 3 points, but second point sometimes absent. Aedeagus usually with paired or unpaired processes, with preatrium about as long as or shorter than shaft. Aedeagal shaft slender or broad in lateral view. Connective median anterior lobe absent or very small, lateral arms long and stem absent or very short, depressed. Notes. The genus is similar to Kapsa Dworakowska, 1972 externally (body slim, dorsum yellow, brown or white, head and face narrow) but the vertex usually has a pair of dark preapical spots. It also differs in having the style with a second extension and the connective without a central lobe (lobe well developed in Kapsa ). The genus is also similar to Ziczacella Anufriev, 1970 in morphology, but the latter differs in having the forewing with a longitudinal zigzag-shaped stripe. Also, Ziczacella differs from Arboridia in having a distinct group of basolateral setae on the male pygofer lobe, and in lacking the well developed second point of the style apex. Distribution. Palaearctic and Oriental regions.
