Large Coreid (female) of about 3cm body length; base colour reddish brown with yellow venation on fore wings and red bands on legs; single red band on antennae where a small flat flap forms. These bugs were plentiful on Acacia sp, clustered in groups of 5 or more (picture #2). Apparently males and females can be told apart by the size of femurs on hind legs, which are very thick in males.
Semi-arid region in El Cimatario nature park, just outside Queretaro.
