本文描述台灣產草蟬屬 (Mogannia Amoyt & Serville) 共五種,分別為草蟬 (M. hebes (Walker))、黑翅草蟬 (M. formosana Matsumura)、琉璃草蟬 (M. cyanea Walker)、姬草蟬 (M. minuta Matsumura)、黃色草蟬 (M. basalis Matusmura)。文中描述各種雌、雄蟲之外部形態、發音器、交尾器之構造,並附有成蟲種級之檢索表。本研究同時記錄寄主植物、棲地環境等生物學資料。另外並使用Microsoft Windows 作業系統下之 PRAAT 與 Sigview32電腦軟體對草蟬、黑翅草蟬、琉璃草蟬及姬草蟬進行聲音分析,製作頻譜圖 (Spectrography)、聲紋圖 (Sonagraphy) 與波形圖 (Waveform),所得各種鳴聲之頻率峰值顯示出種內聲音之專一性。
The taxonomy of genus Mogannia of Taiwan was studied and five species were comprised: M. hebes (Walker), M. formosana Matsumura, M. cyanea Walker, M. minuta Matsumura and M. basalis Matusmura. All species were described in detail and tymbal covering and operculum were illustrated. Key to species was given. Host plants and distribution were provided. Waveforms, sonagraphy and spectrography of M. hebes, M. formosana, M. cyanea, M. minuta were produced with PRAAT and Sigview32 at MS-Windows operation system. Song frequency peaks showed specificity of the genus Mogannia of Taiwan.
