Review of the leafhopper genus Alnetoidia Dlabola (Hemiptera: Cicadellidae: Typhlocybinae: Erythroneurini) from China, with descriptions of two new species Author Cao, Yanghui Author Yang, Meixia Author Zhang, Yalin text Zootaxa 2016 4193 3 573 587 journal article 10.11646/zootaxa.4193.3.7 fe135943-b0bd-4cde-803f-b6ea77b4e266 1175-5326 167246 CC45D5EB-5463-4D82-9CFB-234A0069C0BD Alnetoidia ( Alnetoidia ) gracilis sp. nov. ( Fig. 4 ) Description. Body yellowish, without markings. Abdominal apodemes ( Fig. 4 a) extended to hind margin of 4th sternite. Pygofer side ( Fig. 4 b) with several rigid setae on posterior margin; dorsal appendage sinuated; ventral appendage slim, extended from ventral margin of pygofer side. Subgenital plate ( Fig. 4 e) with group rigid setae near base, row of marginal microsetae from near base to apex, shorter than the basal ones, with 3 macrosetae subbasally along outer margin. Style ( Figs 4 f, g) with apical part footlike. Connective ( Fig. 4 h) broad, lateral arms short and broad. Aedeagal shaft ( Figs 4 i–l) tubular, curved dorsad, paired basal processes slim and long, the length and thickness slightly varies among individuals, some specimens bearing a small spinelike process on lateral margin; dorsal apodeme large in lateral view, preatrium short; gonopore apical on ventral side. Measurement. Male 3.42mm , female 3.45mm . Material examined. Holotype : ♂ , CHINA , Sichuan Prov., Mt. Emei , 950m , 30 x 1999 , coll. I. Dworakowska ; paratypes : 1♂ , 1 xi 1999 , other data same as holotype; 1♀ , 29 x 1999 , other data as holotype; 18♂♂ , Sichuan Prov., Ya’an , Hongta Botanic Garden , Pterocarya stenoptera , 12 vii 2010 , coll. Cao Yanghui . Host. Pterocarya stenoptera . Remarks. The new species is similar to A. ( Alnetoidia ) dujuanensis Song & Li , but differs in having the pygofer dorsal appendage shorter, the aedeagal shaft distinctly curved dorsad and the paired basal processes shorter and extended from the dorso-lateral margins of the shaft. Etymology. The specific epithet is derived from the Latin word “ gracilis ”, referring to the slender lateral processes of the aedeagal shaft.
