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. The song of Dundubia vaginata from peninsular Malaysia is clearly different from Bornean populations' song. Short, narrow banded frequency modulated (FM) first part of bipartite phrases from Borneo resembles the end short part of phrases from peninsular Malaysia. The longer broadband 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 to be not a single taxon but rather a complex of speciesRaziskali smo napeve škržada Dundubia vaginata Fabricius 1787. Analiza napevov je bila narejena na 21 posnetkih različnih osebkov s štirih najdišč v celinski Maleziji in 10 posnetkih z enega najdišča na Borneu. Rezultate smo primerjali z že objavljenim opisom napevov z Bornea. Napevi škržada D. vaginata iz celinske Malezije se jasno razlikujejo od napevov bornejske populacije. Kratki, ozkopasovni in frekvenčno modulirani prvi deli dvodelne fraze bornejske populacije so analogni kratkim zadnjim delom fraze populacije iz celinske Malezije. Daljši širokopasovni deli fraz obeh populacij imajo podobne lastnosti. Na dveh najdiščih v celinski Maleziji smo posneli napev nepoznane simpatrične vrste škržadov. Napev je zelo podoben napevu bornejske populacije D. vaginata. Največja razlika je v neenaki dolžini fraz tega neidentificiranega, vendar verjetno sorodnega taksona. Naše raziskave kažejo, da je Dundubia vaginata v resnici kompleks vrstTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaPrirodoslovni muzej Slovenije
