Background The singing cicadas (Hemiptera: Cicadidae) of Bulgaria were poorly known. There are published records for 14 species: Cicada orni, Lyristes plebejus, Cicadatra atra, Cicadatra hyalina, Cicadatra persica, Cicadetta montana, Cicadetta mediterranea, Dimissalna dimissa, Oligoglena tibialis, Tympanistalna gastrica, Pagiphora annulata, Saticula coriaria, Tibicina haematodes and Tibicina steveni. New information Two species from this list were doubtful in the beginning of our study, since Tympanistalna gastrica is distributed in central and southern Portugal and Saticula coriaria is a north African species. We checked three major institutional collections housed in Sofia, Bulgaria: the National Museum of Natural History (SOFM), the Institute of Zoology (ZISB) and the Biology Faculty of Sofia University "St. Kliment Ohridski" (BFUS). We confirmed 11 of the species mentioned in literature, except Cicadetta mediterranea and found two additional species: Cicadatra platyptera and Cicadetta macedonica (the specimens in BFUS were bioacoustically confirmed). Based on this knowledge, we further investigated the singing cicadas of Bulgaria with the use of morphological and bioacoustic methods in the years 2008, 2009, 2010, 2012, 2016, 2018 and 2019. We were not able to confirm the presence of Cicadatra persica and Cicadetta mediterranea, but found three additional species: Cicadetta brevipennis s. lat., Cicadetta cantilatrix and Tettigettula pygmea. Using the bioacoustic methods, we also detected unknown singing patterns, which could belong to three or four additional taxa, which need to be described. The Bulgarian fauna of singing cicadas at the moment consists of 16 confirmed and 3-4 potential species.

基于生物声学的保加利亚鸣蝉（半翅目：蝉科）清单和临时图谱

背景保加利亚的鸣蝉（半翅目：蝉科）鲜为人知。已发表记录的有 14 个物种：鸟蝉、Lyristes plebejus、Cicadatra atra、Cicadatra hyalina、Cicadatra persica、Cicadatra montana、Cicadatta mediterranea、Dimissalna dimissa、Oligoglena tibialis、Tympanistalna gasta、Pagiphora annulata、Saticula coriaria、Tibicina haematodes 和 Tibicina steveni。新信息 该列表中的两个物种在我们的研究开始时是值得怀疑的，因为胃鼓室菌分布在葡萄牙中部和南部，而 Saticula coriaria 是北非物种。我们检查了保加利亚索非亚的三个主要机构收藏：国家自然历史博物馆 (SOFM)、动物学研究所 (ZISB) 和索非亚大学“St. Kliment Ohridski”(BFUS) 生物学系。我们确认了文献中提到的 11 个物种，除了地中海蝉，并发现了另外两个物种：蝉翼和马其顿蝉（BFUS 中的标本经过生物声学证实）。基于这些知识，我们在 2008 年、2009 年、2010 年、2012 年、2016 年、2018 年和 2019 年使用形态学和生物声学方法进一步调查了保加利亚的鸣蝉。我们无法确认桃蝉和蝉的存在。 Cicadetta mediterranea，但发现了三个额外的物种： Cicadetta brevipennis s。纬度， Cicadetta cantilatrix 和 Tettigettula pygmea。使用生物声学方法，我们还检测到未知的歌唱模式，它们可能属于需要描述的三个或四个额外的分类群。
