Wing pattern variation and DNA barcodes defy taxonomic splitting in the New Zealand Pimelea Looper Notoreas perornata (Walker) (Lepidoptera: Geometridae: Larentiinae): the importance of populations as conservation units.

The endemic Notoreas perornata (Walker, 1863) complex (Lepidoptera: Geometridae: Larentiinae) from the North Island and northern South Island of New Zealand is reviewed. Larvae feed on Pimelea spp. (Thymelaeaceae), frequently in highly fragmented and threatened shrubland habitats.

A new leaf-mining moth from New Zealand, sp. nov. (Lepidoptera, Gracillariidae, Gracillariinae), feeding on the rare endemic shrub (Lamiaceae), with a revised checklist of New Zealand Gracillariidae.

Hoare & Patrick, (Lepidoptera, Gracillariidae, Gracillariinae) is described as a new species from New Zealand. It is regarded as endemic, and represents the first record of its genus from the southern hemisphere. Though diverging in some morphological features from previously described species, it is placed in genus Triberti, based on wing venation, abdominal characters, male and female genitalia and hostplant choice; this placement is supported by phylogenetic analysis based on the COI mitochondrial gene.
