Field Notes
Description:
A short, squat winged female Tettigoniid about 2.5 cm in length. Her coloring is perfect for tree trunk camouflage. She has black triangular markings on the abdomen and beautiful pink eyes. The wings seem much too small to carry her weight if she were to fly. The ovipositor is short and curved and has tiny teeth on the upper edge. You can see the tympanum for "hearing" on the front tibia in several of the pictures. Family Tettigoniidae. This is only a recently described species and the the type locality is San Cristobal de Las Casas, Chiapas, Mexico (http://orthoptera.speciesfile.org/Common/basic/Taxa.aspx?TaxonNameID=11…).
Habitat:
Garden at night, semi-rural residential area, San Cristobal de Las Casas, Chiapas, Mexico 2,200 meters.
Notes:
Many thanks to Holgar Braun for the identification.
Studies in Mexican Tettigoniidae: A new genus of Copiphorini and the first description of male Conocephalus (Aphauropus) leptopterus Rehn and Hebard and the female of Insara acutitegmina. Fontana, Buzzetti, Mariño-Pérez & García García states "... Tribe Insarini Rehn and Hebard, 1914 and Insara Walker, 1869.
