Discussion and differential diagnosis. Both occurring in Northern Queensland, the habitus and head ratio of Pollanisus incertus are close to those of P. jirrbal sp. n., but the former differs in its slightly smaller compound eyes and the different larval host-plant. The holotype of P. incertus was obtained from a larvae collected on Tetracera nordtiana ( Figs 143–145 ) ( Tarmann 2004). Pollanisus species 5 (sensu Tarmann 2004) shares the same head ratio ( Table 10 ) and the nocturnal activity with P. incertus . and is therefore considered to belong to the same species.

Phenology and bionomics. Eggs and larvae ( Figs 146–148 ) were mainly collected on Hibbertia scandens and rarely on Tetracera nordtiana (both Dilleniaceae ). These two larval host-plants are often growing together. Most of the imagines ( Figs 149, 150 ) were collected at night with U. V. light.

The collected larvae found feeding on T. nordtiana , were easily moved to H. scandens (rearing observation BM).
