Recent evidence on craniodental morphology suggests the acceptance of three species of lion tamarins (Leontopithecus). Confirmatory evidence is presented here using the morphology of long-call vocalizations recorded from several individuals of each type of lion tamarin. Recordings were made of Leontopicthecus rosalia, Leontopithecus chrysopygus, and Leontopithecus chrysomelas at the Centro de Primatologia do Rio de Janeiro (FEEMA) and of L. rosalia at Monkey Jungle in Florida. Thirty separate parameters were measured, and 17 of them differed significantly between populations. In general, L. chrysomelas had higher pitched calls with shorter note duration, while L. chrysopygus, the larger of the animals, had lower pitched calls with longer note duration. L. rosalia was either intermediate to the other two populations or resembled L. chrysopygus. Thus, the results from the analysis of vocal structures closely paralleled the results obtained with more traditional taxonomic methods and suggests that the quantitative analysis of vocal strucures can be a useful adjunct in taxonomy.
近期有关颅骨牙齿形态学的证据表明，狮狨属（Leontopithecus）应接受三种物种。本文通过对每种狮狨几个个体记录的长叫声形态提供了确证性证据。在里约热内卢灵长类动物中心（FEEMA）对金头狮狨（Leontopicthecus rosalia）、金臀狮狨（Leontopithecus chrysopygus）和黑须狮狨（Leontopithecus chrysomelas）进行了录音，并在佛罗里达的猴林对金头狮狨进行了录音。测量了30个不同参数，其中17个在不同种群间存在显著差异。总体而言，黑须狮狨的叫声音调较高，音符持续时间较短，而体型较大的金臀狮狨叫声音调较低，音符持续时间较长。金头狮狨要么处于其他两个种群之间中间状态，要么与金臀狮狨相似。因此，对声音结构的分析结果与用更传统分类方法获得的结果密切平行，表明对声音结构的定量分析可成为分类学中有用的辅助手段。
