Abstrakt		Vibrational signals (songs) were recorded and compared for two stink bug species, Thyanta pallidovirens andT custator accerra. Females of both species produced two songs Male T pallidovirens also produced two songs, whereas maleT c. accerra produced four. Sangs emitted by females of both species were comparable in structure and function, as was one of the male-produced songs During the courtship phase of mating behavior, males of both species emitted a song with similar function but different temporal and spectral properties. Basic properties of songs, such as the dominant frequencies, were similar to those of songs of other pentatomid specie but the extensive use of frequency modulation and overlapping duets were novel. Differences in songs, combined with differences in male-produced pheromones, may play a role in the reproductive isolation of these congeners.
