Elevation of a Subspecies of tibicen (Hemiptera: Cicadoidea: Cicadidae) to a Full Species (original) (raw)

2011, The Southwestern Naturalist

The Tibicen bifidus species complex is composed of T. b. bifidus and T. b. simplex . We analyzed biogeographical, morphological, and physiological parameters to determine if these taxa represent two species. There are significant differences in biogeography, as well as selection of host-plant and several morphological characteristics. Comparisons of their calling songs approach statistical significance. Sound-pressure level of alarm calls and thermal responses of the two taxa do not differ significantly. Our data suggest that the two taxa represent distinct species.
