Anaxipha hyalicetra sp. n. (Gryllidae, Trigonidiinae), a new sword-tailed cricket species from Arizona

Abstract

A new Anaxipha species is described from a locality in southeastern Arizona adjacent to the border with Mexico. The species is unique among the North American fauna by virtue of the broad tegmina, distinctive male genitalia, and calling song phrased in an irregular chirp with a variable pulse train rate. The possibility that the behavioral repertoire of this species includes aggressive song as well as calling song is discussed.
