本文描述一種產於臺灣北部山區，屬於姬春蟬屬varicolor種群的新蟬種－－翠峰姬春蟬(Euterpnosia ampla sp. nov.)。相較於其他近緣種，本種體形明顯較大且雄性腹部形狀較寬。在varicolor種群中本種偏暗的體色與高山姬春蟬(E. alpine)的體色十分近似，但陽莖形態顯示本種可能與臺灣東部所產的新港山姬春蟬(E. madawdawensis)較為近緣。

A new species of cicada, Euterpnosia ampla sp. nov., belonging to the varicolor group, was described from Northern Taiwan. This species is distinct from other allied species in its large body size and wider male abdomen shape. The species is similar to E. alpina in its dark coloration but the morphology of aedeagus shows that E. ampla should be more closely related to E. madawdawensis from Eastern Taiwan.
