Synonyms and other taxonomic changes
Dichopetala Brunner von Wattenwyl, 1878
Obolopteryx Cohn, Swanson & Fontana, 2014
Explanation of Names
Most of our U.S. species formerly placed in the genus Dichopetala were transferred to a new genus, Obolopteryx, by Cohn, Swanson, & Fontana 2014 (with the exception of D. pollicifera, which was placed in genus Planipollex). The genus Dichopetala now contains only one species D. mexicana, which is not found in the U.S.
Numbers
7 spp. in our area, 14 spp. total (1)(2)
Size
13-25 mm body length (D. brevihastata)
Identification
Medium-sized, robust, flightless katydids. Forewings of females essentially absent (present as small scales). Males have short forewings used only in stridulation. Determination of species requires examining characters including the male cercus, female subgenital plate, and ovipositor.
Range
sw. US, extending into Mexico(2); D. brevihastata is widespread (se. AZ to so. TX), our other spp. largely restricted to TX(3)
Habitat
Species occur in a wide range of habitats, including mountains, low woodlands, shrublands and deserts (Cohn, Swanson, & Fontana 2014)
Season
July-October (D. brevihastata)
Food
Probably mostly herbivorous. Some species reported to eat flowers(4)
