A specific mate-recognition system involved in speciation and phylogeny of the world Lipara-species was investigated on the basis of acoustic, physical and behavioral pro-perties of the male and the female vibratory signals. Acoustic data obtained here were on 8 known and 3 unknown species of total 611 individuals and 50,944 signals occurred in the male mating behavior. Male signals of another genus, Calamoncosis, which is closely related to Lipara phylogenetically, were also examined to consider the state of primitive signal pattern. After examining their acoustic parameters with oscillographic and frequency spectral apparates between populations of different species or different populations of the same species, multivariate statistical analyses were performed for culculating the significancy of difference, dissimilarity, and for doing cluster group-ing. Physical properties of the male signals among different populations of geographi-cally isolated in the same species were found to be individually specialized to some extent, and this explained the degree of ancient possession of common gene-pool and that of isolation period occurred by incident geographic separation of the reedy marshed. In some species, male signals of certain populations showed their origin of invasion in common from continental element of China, or evidence brought about random drift resulted from its long-time isolation from neighbor populations. In this occasion, 2 new sibling species of the rufitarsis-group in Japan, 1 new sibling species of the Lucens-group in Soviet Union, and 1 unknown species of the rufitarsis group in the Ishigaki Is. were found for the first time.

本文从振动信号的声学、物理和行为特征出发，探讨了世界脂鲤属（Lipara-species）种的一个特殊的配偶识别系统。在此基础上，对8种已知种和3种未知种共611只个体进行了声学数据采集，共采集到50,944个雄性交配行为信号。雄性信号的另一个属，Calamoncsis，这是密切相关的Lipara遗传，也进行了检查，以考虑原始信号模式的状态。在不同种间和同种不同种间用声波图和频谱分析仪测定其声学参数后，进行多元统计分析，计算差异的显著性、相异性，并进行聚类。同一种内地理隔离的不同种群间雄性信号的物理特性具有一定的个体特化性，这解释了芦苇沼泽偶然地理隔离所造成的共同基因库的古老占有程度和隔离期的长短。某些种的雄性信号表明它们共同起源于中国大陆成分，或与邻近种群长期隔离而导致随机漂移。本文报道了日本rufitarsis组的2个新兄弟种、苏联Lucens组的1个新兄弟种和石垣群岛rufitarsis组的1个未知种。首次被发现。
