摘要
The eight valid species previously placed in the agalliine leafhopper genus Chromagallia Linnavuori （C. saucia （StUd）, C. carvalhoi Gongalves et al., C. lamasi Gongalves et al., C. lanceolata Gongalves et al., C. paraguayensis Gongalves et al., and C. zanolae Gongalves et al.） are reviewed based on comparative morphological studies, and the concept of this genus is narrowed to include only three species with yellow maculae （C flavofasciata （Stal）, C. longistilata （Coelho ＆ Durra）, and C. rodriguesoi sp. nov.）. A redescription and revised diagnosis of the genus are provided. The type species, C. flavofasciata, is redescribed and the female of C. longistilata is described and illustrated in detail for the first time. Two new genera, Rubragallia, and Neorubragallia are erected to include the six species with red maculae formerly placed within Chromagallia. Rubragallia includes R. saucia （Stal） n. comb., and R. paraguayensis （Goncalves et al.） n. comb.. Neorubragallia includes N. lamasi （Goncalves et al. ） n. comb., N. lanceolata （Goncalves et al ） n. comb., N. zanolae （Goncalves et al.） n. comb., N. carvalhoi （Goncalves et al.） n. comb., and N. mervini sp. nov.. Keys to species of the three genera, and taxonomic notes are provided.
基于比较形态学对曾归入圆痕叶蝉亚科铬黄圆痕叶蝉属Chromagallia的8个有效种(C. saucia(St l), C. flavofasciata (St l), C. longistilata (Coelho & Dutra), C. carvalhoi Gon alves et al., C. lamasiGon alves et al., C. lanceolata Gon alves et al., C. paraguayensis Gon alves et al.和 C. zanolae Gon alves etal.)进行了订正,明确了该属的范围仅限于具有黄斑的3个种(C. flavofasciata (Stl), C. longistilata(Coelho & Dutra) 和 C. rodriguesoi sp. nov.),对该属进行了重新描述,并修订了鉴别特征。此外,对模式种 C. flavofasciata 进行了重新描记,首次提供了 C. longistilata 的雌性生殖器图,并作了描记。把曾归入铬黄圆痕叶蝉属 Chromagallia 具有红斑的6个种移出并新建了2个新属:Rubragallia 和Neorubragallia,其中 Rubragallia 包括 R. saucia (Stl) n. comb.和 R. paraguayensis (Gon alves et al.) n.comb., Neorubragallia 包括 N. lamasi (Gon alves et al.) n. comb., N. lanceolata (Gon alves et al.) n. comb.,N. zanolae (Gon alves et al.) n. comb., N. carvalhoi (Gon alves et al.) n. comb. 和 N. mervini sp. nov.。文中提供了3个属的分种检索表,并对不同种的分类地位及3个属的划分进行了讨论。
