Abstract

Four species of Cyrtoxipha occur in the United States. C. columbiana Caudell occurs throughout the southeastern States, C. gundlachi Saussure is restricted to peninsular Florida, and C. nola and C. confusa, n. spp., are known only from the mangrove areas of the south Florida coast. The songs of these species are distinctive in the field, and differences in pulse rate and rhythm are apparent from analyses of field and laboratory tape recordings. Other characters not previously used, such as male genitalia and stridulatory file, are useful in distinguishing the species of Cyrtoxipha. The stridulatory files of columbiana and gundlachi show geographic variation.
