A new species of Piarosoma Hampson, 1893 (Lepidoptera, Zygaenidae, Procridinae, Artonini) from Arunachal Pradesh, India.

A new species, Piarosoma arunachalensis sp. nov., is described and illustrated based on external characters and the genitalia of two male specimens from Tale Wildlife Sanctuary, Lower Subansiri District, Arunachal Pradesh, India. The new species is distinguished from other Piarosoma by a combination of: a) presence of large hyaline patches on the wings, b) the absence of any white or yellow markings on the patagia and the abdominal segments, and c) differences in male genitalia.

Revision of the genus Pollanisus Walker, 1854(Lepidoptera: Zygaenidae: Procridinae).

The genus Pollanisus is endemic for Australia. Its revision is mainly based on head studies and includes 21 known species and 7 new species, Pollanisus jumbun sp. n., Pollanisus yugambeh sp. n., Pollanisus horakae sp. n., Pollanisus worimi sp. n., Pollanisus kalliesi sp. n., Pollanisus jirrbal sp. n. and Pollanisus nocturna sp. n. Moreover, two species, Pollanisus eumetopus syn. n. and Pollanisus eungellae syn. n., are synonymized with Pollanisus acharon (Fabricius, 1775). The status of 8 unnamed species (Tarmann, 2004) is discussed. New data on the phenology and bionomics are provided. New host plants in the genus Hibbertia (Dilleniaceae) are reported.

Phylogenetic position of the 'extinct' Fijian coconut moth, Levuana iridescens (Lepidoptera: Zygaenidae).

Levuana iridescens Bethune-Baker, 1906, a day-flying moth purported to be endemic to the Fijian Island of Viti Levu and a former pest of its coconut palm trees, was last observed in 1956 and has been officially declared extinct by IUCN since 1996. The controversial classical biological control method that resulted in the (presumed) demise of this moth has given this species an iconic status in biological control studies. We investigated the sister-group relationships and phylogenetic placement of this moth using NGS-obtained ancient DNA sequences from museum specimens of L. iridescens collected in the 1920s, combined with 31 morphological characters used in earlier studies and 2 new characters. Our findings show that Levuana is most closely related to the Australian genus Myrtartona. The significance of these findings is discussed.

"Ino Budensis var. Mollis" Grum-Grshimailo, 1893 (Lepidoptera: Zygaenidae) from Eastern Asia recognized as a valid species on the base of morphological and molecular analysis.

Based on morphological and molecular data, Ino budensis var. mollis Grum-Grshimailo, 1893, from China, so far treated as a synonym of Jordanita (Roccia) paupera (Christoph, 1887), is here recognized as a good species, Jordanita (Roccia) mollis (Grum-Grshimailo, 1893), stat. nov. This species is recorded as new for the fauna of Russia and Korea. An identification key for this species is provided.
