9442E457FB4357A5BEFC9664198DA294.taxon	description	Fig. 3 A-F, 4 A-D, 5 A, C, 6 A-F	en	Collins, Nancy, Lightfoot, David C. (2022): A new species of tree cricket (Orthoptera, Gryllidae, Oecanthinae) from Chihuahuan Desert gypsum dunes in the United States and a key to the nigricornis species group. Journal of Orthoptera Research 31 (2): 181-189, DOI: http://dx.doi.org/10.3897/jor.31.79036, URL: http://dx.doi.org/10.3897/jor.31.79036
9442E457FB4357A5BEFC9664198DA294.taxon	diagnosis	Diagnosis. - The antennal markings of O. beameri sp. nov. can total two, three, or four, with the medial mark on the scape usually broken into two pieces (Figs 3 C, 4), while O. quadripunctatus has either two or four marks with the medial mark on the scape being a solid post, and O. celerinictus always has a solid medial mark on the scape and never lacks the upper outer mark on the scape and is never round. The two antennal marks on the pedicel of O. walkeri (Collins and Symes 2012) touch, and those of O. argentinus touch or nearly touch, while the marks on O. beameri sp. nov. do not. The male and female subgenital plates of O. beameri sp. nov. (female: wide shallow notch as in Fig. 5 A; male: rounded end as in Fig. 5 C) can be distinguished from O. quadripunctatus (female: deep narrow notch as in Fig. 5 B; male: tapered to a rounded tip as in Fig. 5 D). When next to each other, a male O. beameri sp. nov. has a lighter coloring and smaller proportion of tegmen width to abdomen width than a male O. quadripunctatus (Suppl. material 5). Oecanthus beameri sp. nov. lacks the dark black lines across the proximal portion of the hind tibiae that are very common on O. celerinictus, but faint lines can be present (Fig. 3 F). The deep black setae on the hind femora of O. salvii (Collins and Schneider 2020) are not present in O. beameri sp. nov. See below for more detailed diagnostic information.	en	Collins, Nancy, Lightfoot, David C.

9442E457FB4357A5BEFC9664198DA294.taxon	etymology	Etymology. - Specific epithet in recognition of Raymond Beamer who collected the specimens in 1932 that were discovered in the ANSDU collection in 2019. The common name, White Sands tree cricket, is for the location where this species was discovered with high potential for endemism.	en	Collins, Nancy, Lightfoot, David C.

9442E457FB4357A5BEFC9664198DA294.taxon	description	Female paratype description. - (n = 1) Latticed vein pattern on translucent greenish-white wings. Abdomen pale white (Fig. 3 E). Body length 11.5 mm; pronotal length 2.0, distal pronotal width 2.0; hind femur length 7.0; cerci 4.5; ovipositor length 3.5. The tip of the ovipositor flared (Fig. 6 F) and extending just beyond the tips of the cerci. Distal end of subgenital plate with a wide, shallow notch (Fig. 5 A). The only female collected (Fig. 3 E) was missing the distal ends of the wings, thus dorsal photos not included.	en	Collins, Nancy, Lightfoot, David C.
