TABLE 15 . Head ratio data. Pollanisus empyrea . P. amethystina . Discussion and differential diagnosis. Pollanisus empyrea ( Fig. 212 ) has uniformly brown narrow forewings covered with a few metallic coppery scales, more densely at the base of the forewing, while P. cupreus and P. nielseni are bigger, and their forewings are widely covered with coppery to golden metallic scales. The head ratio of P. empyrea is different from those of Pollanisus cupreus and P. nielseni . P. empyrea differs in habitus from P. amethystina , which has green metallic scales on the forewing upperside and on the upper side of the abdomen. Their head ratios are slightly different. Phenology and bionomics. Pollanisus empyrea is active during the day, when disturbed and at night ( 1 ). P. empyrea is linked to its larval host-plant Hibbertia cuneiformis (Dilleniaceae) ( Figs 213, 214 ), and it is assumed to feed also on H. commutata (Axel Kallies, pers. obs.). The larvae of P. empyrea ( Fig. 215 ) and P. amethystina ( Fig. 218 ) are similar in habitus and cannot be used for differentiation.
