Discussion and differential diagnosis. Pollanisus viridipulverulenta is the largest Pollanisus species in Eastern and South-Eastern Australia, including Tasmania ( Tarmann 2004). Pollanisus apicalis can be difficult to separate from small individuals of P. viridipulverulenta , especially the head ratios are similar with the height of the compound eye slightly bigger in P. apicalis .

However, the more triangular wing shape of the forewing,the broader hindwing in Pollanisus viridipulverulenta and the medially slightly translucent hindwings in P. apicalis usually separate the two species without problem ( Tarmann 2004). With its very large compound eyes, Pollanisus nocturna sp. n. cannot be confused with P. viridipulverulenta and P. apicalis .

Phenology and bionomics. Pollanisus viridipulverulenta is mainly collected flying in daytime and rarely at night. The known host-plants are Hibbertia obtusifolia , H. sericea and H. stricta (all Dilleniaceae ) ( Tarmann 2004).
