【摘要】 <正> 白颈飞虱 Sogata sirokata系Matsumura et Ishihara于1945年作为新种发表,1963年Fennah将其移至绿飞虱属Chloriona白背飞虱亚属内,后白背飞虱亚属又被提升为白背飞虱属Sogatella。我们经过研究,认为白颈飞虱不应置于长唇基飞虱属SogatoDistant或白背飞虱属Sogatella Fennah内,为此,作者将其与广东省和福建省采集的3新种一并建立无皱飞虱属Paracorbulo(新属),以白颈飞虱为模式种,新属新种描更多还原

【Abstract】 The present paper reports a new genus and three new species of the tribe Delphacini of the subfamily Delphacinae collected from China. The type specimens are deposited in Nanjing Agricultural College and Anhui Agricultural College respectively.Paracorbulo Tian et Ding, gen nov. This new genus is separated from Sogata Distant by the submedian carinaeof the vertex united before the apex, by the clypeus relatively short and by the second segment of antennae longer than broad (less than 3:1); from Sogatella Fennah by the submedian carinae of vertex, by the pale medial dorsal band, and by the shape of the diaphragm and aedeagus of male genitalia. Type species: Sogata sirokata Matsumura et Ishihara.Kew to species1(2) Frons swollen abruptly under the level of lower margin of eyes, vertexsubrectangularly rounding into frons, the outer apical angle of genitalstyles triangular, maerop. f. length: (?) 1.7mm, (?) 2.4mm.
