 8. Hemelytra with both yellow to brownish yellow patches dissimilar in size, the subbasal patch an extremely small elongate stripe on corium adjoining claval suture and, distal (second) one a large patch about halfway on inside of hemelytra on apical area of corium and base of membrane, covering most of AIC and narrow basal area of AEC (Fig. 5A&D).............................................................................................
