Abstract

The genus Anaxipha has at least 13 North American species, eight of which are described here. Ten species fall into these three species groups: exigua group (exigua Say, scia Hebard and n. spp. thomasi, tinnulacita, tinnulenta, and tinnula); delicatula group (delicatula Scudder and vernalis n. sp.); litarena group (litarena Fulton and rosamacula n.sp.). The remaining three (imitator Saussure, fultoni n.sp., and calusa n.sp.) have no close relatives among the other species. Most new species were initially distinguished by their calling songs, and in most cases sympatric populations proved cleanly separable by features of male genitalia and tooth-counts of stridulatory files. Species groups were based mostly on comparisons of male genital structures and the results of DNA barcoding. Species are here characterized not only by their songs and morphology, but also by geographical, ecological, and seasonal distributions. […]
