摘要

After examining topotypic specimens of Euterpnosia varicolor Kato, I found that a new species is misidentified and described as E. varicolor in the most recent review of Cicadidae from Taiwan. I herein redescribed E. varicolor basing on topotypic specimens and also described the new species, E. alpina, and another allied new species, E. madawdawensis, from Taiwan. The membranous vesica and sclerotized projections on the apical part of aedeagus were described and proven to be reliable for identifying these three species. I also analyzed and characterized the distinct calling song of each species. After the taxonomic problems of E. varicolor were discussed, a neotype of E. varicolor was designated from topotypic specimens to prevent further confusion and misidentification.

在檢查來自模式產地的太平姬春蟬（Euterpnosia varicolor Kato）的標本之後，作者發現在一篇最新的臺灣產蟬科訂正中一個姬春蟬屬的新種被錯誤鑑定並且被描述為太平姬春蟬。因此作者根據來自模式產地的標本重新描述了太平姬春蟬並且描述了該新種以及另一個近緣的新種。作者描述了陽莖端部的膜狀囊以及骨化突起並證實這些構造在鑑別這三種姬春蟬時相當可靠。此外作者也分析了每種姬春蟬的嗚聲。最後作者討論了太平姬春蟬在分類上的問題，並在來自模式產地的太平姬春蟬標本中指定一隻雄蟬為新模式以避免日後的混淆與錯誤鑑定。
