A new species of the genus Ivela Swinhoe (Lepidoptera, Erebidae, Lymantriinae) from Guangdong, China.

Ivelayini sp. nov., is described from Guangdong, China based on morphological characters and molecular data. Adults, including genitalia and wing venation, and pupa are illustrated and compared to those of similar species. A key to Chinese Ivela species is provided. Assignment of the new species to Ivela Swinhoe is based primarily on a molecular phylogenetic analysis and is corroborated by morphology. Life histories of I.yini and Dendrophlepssemihyalina Hampson are discussed.

Review of the genus Daplasa Moore (Lepidoptera, Erebidae, Lymantriinae) from China, with description of new species.

The tussock moth genus Daplasa Moore, 1879 is reviewed from China. Hitherto four species are recognized, where one new species, D. nivisala sp. n., is described and one new combination D. melanoma (Collenette, 1938) comb. n. is proposed. Adults and their genital structures are provided, together with a key to the species of Daplasa with the occurrence in China.

Morphological and molecular evidence for a new species of the genus Panolis Hübner, [1821] (Lepidoptera: Noctuidae).

A new species of the genus Panolis Hübner, [1821], P. xundian sp. nov., is described and illustrated from southwestern China. It is well-defined morphologically by the male genitalia, with a well-developed pollex at the distal terminal of the sacculus and a broad, ventrally concave cucullus, the female corpus bursae with four long signum-stripes. Based on a 658 bp segment of the mitochondrial cytochrome c oxidase subunit I gene, we report the pairwise genetic distance of 2.5% from its allied species P. exquisita Draudt, 1950. Molecular phylogenetic analyses using three genes (2189 bp in total length) indicate that the new species belongs to the P. exquisita species group.

A new species of the genus Polyphena Solovyev, 2014 (Lepidoptera: Limacodidae) from China.

Polyphena chongzuoensis sp. nov. is described from China, as the twelfth species of Polyphena Solovyev, 2014. This new species is morphologically similar to P. bana (Cai, 1983), but differs in male genitalia from the latter by short spurs of anellus and aedeagus without obvious apical processes. Male adult and its genitalia are illustrated. The new species is supported molecularly by the analysis of pairwise genetic distances from a 658 bp of the mitochondrial cytochrome c oxidase subunit I gene, with the minimum distance value of 6.4% from its allied species P. annae.
