| 摘 要： | 鼻优草螽Euconocephalus nasutus(Thunberg)]和苍白优草螽Euconocephalus pallidus (Redtenbacher)]外形相似，但其鸣声特征和发声器的结构明显不同。鼻优草螽鸣声的每个脉冲组由4个脉冲串构成。脉冲组持续时间4．5ms脉冲组间隔为1．8ms，主能峰频率为11．37kHz。苍白优草螽鸣声的每个脉冲组仅由1个脉冲串构成，脉冲组持续时间1．6ms，脉冲组间隔为4．3ms，主能峰频率为11．03kHz，鼻优草螽发声锉较弯曲，中部稍粗壮，两端稍细，苍白优草螽发声锉较直，呈棒状。

| Abstract: | Euconocephalus nasutus (Thunberg) and E. pallidus (Redtenbacher) were quite similar in morphology,but their songs and the stridulatory organs were obviously different. The chirp of the songs of E. nasutus lasts 4 5?ms,consisting of 4 pulse strings with an inter chirp interval of 1 8?ms,and the frequency of highest power peak is about 11 37?kHz. The chirp of the songs of E. pallidus has only one pulse string with an inter chirp interval of 4 3?ms. The pulse string duration is 1 6?ms and the frequency of highest power peak is about 11 03?kHz. The file of E. nasutus is curved with thin ends and enlarged middle portion. The file of E. pallidus is straight,and slightly widened in the middle portion. |
