Abstract

A new species of tree crickets, Oecanthus beamerisp. nov., is described from the gypsum dunes of White Sands National Park in New Mexico, United States. The new species is currently known only from the type locality, where it appears to be specific to the gypsophile plant hoary rosemary mint (Poliomintha incana). This new species has the narrowed tegmina and calling song that are found in the nigricornis species group. Although it has morphological similarities to O. quadripunctatus and O. celerinictus, there are differences in the subgenital plates, tegminal measurements, coloring, tibial markings, song frequency, and song pulse rate. This new species has been given the common name White Sands tree cricket. We provide a key to all species in the nigricornis group. Video and song recordings are available online as Suppl. materials 1–8.
