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).
