Oliarces clara, Moth Lacewing - Oliarces clara Anza-Borrego Desert State Park, San Diego County, California, USA April 29, 2009 Size: BL about 17 mm
This roach and several others were found dead in the primitive bathroom at Split Mountain. This is real desert! I collected three of them. The body length of the photograph is 17 mm with 23 mm to the wing tip. Another is 23 mm with 27 mm to the wing tip.
The closest match I could find is Eremoblatta subdiaphana in Helfer's How to Know the grasshoppers,.... called the Hairy Desert Cockroach. Notice the hairy head. This species is the only one in the book with obvious hair around the head. But, the key is a front tibia with seven spines at tip. We cannot find this feature. Instead the tibia seems to have spines going up the side. We tried to check this trait on all three specimens, but the legs are curled up underneath and are very difficult to see. BugGuide Photo # 185354 is of the Eremoblatta genus. There seems to be just one species?
Any help will be much appreciated.
