 <tt>Abstract - We investigated the songs of the cicada Dundubia vaginata 
 Fabricius 1787. The sound emission analysis is based on 21 recordings 
 of different individuals from four localities in Peninsular Malaysia 
 and 10 recordings from one locality in Borneo. The results were 
 compared to the published description of song pattern from Borneo by 
 Riede & Kroker (1995). The song of Dundubia vaginata from Peninsular 
 Malaysia is clearly different from Bornean populations&#x2019; song. Short, 
 narrow banded frequency modulated (FM) first part of bipartite phrases 
 from Borneo resembles the last short part of phrases from Peninsular 
 Malaysia. The longer broad band parts of phrases in both populations 
 have similar properties. A song pattern of unknown sympatric cicada 
 species resembling the song of Bornean population has also been 
 recorded at two localities in Peninsular Malaysia. The most prominent 
 difference is unequal length of phrases in the song of this 
 unidentified but probably closely related cicada species. Dundubia 
 vaginata seems not to be a single taxon but rather a complex of 
 species.</tt><br>

 Another tropical cicada song has been published in the journal Scopolia 
 54: 1-15 (2004):
 
 Frequency modulated song of the cicada Maua albigutta (Walker 1856) 
 (Auchenorrhyncha: Cicadoidea) from South East Asia

 Abstract: The song and calling behaviour of the cicada Maua albigutta 
 (Walker, 1856) from S.E. Asia is described. The majority of the 
 investigations has been carried out in the Endau Rompin National Park, 
 Malaysia. The calling song comprises three main parts (A - C) with 
 characteristic amplitude and, especially in the third part, with 
 intense frequency modulation. The duration of the whole song is 38.2  
 5.1 s and is often repeated without interruption many times in 
 succession. Amplitude and frequency modulation is accompanied with 
 movements of the abdomen and during frequency modulated calls also with 
 changes of its shape. Songs from other localities (Kuala Lompat ? 
 Malaysia, Krui ? Sumatra) are slightly different but clearly follow the 
 same general pattern, and can be attributed with certainty to the same 
 species.
