The monotypic genus Silvispina M. Wang & Soulier-Perkins, gen. n. and new species S. changpotou M. Wang & Soulier-Perkins, sp. n. belonging to the family Lophopidae Stål, 1866, from Yunnan Province in China, is described and illustrated. The peculiarity of the first metatarsal segment of this genus is stressed and the taxonomic position of this new genus is discussed. The ornamentation and shape of metatibia and first tarsal segment (the characters that currently distinguish the subfamilies Menoscinae and Lophopinae) do not agree with either subfamily and the new genus is placed as incertae sedis in the Lophopidae. The genus Ridesa Schumacher, 1915 is removed from the family Lophopidae and placed in the Achilidae., Menglin Wang, Yinglun Wang, Adeline Soulier-Perkins., and Obsahuje bibliografii
The oldest butterfly fossil known, which was formed about 55 Ma in what is now Denmark, is described. The fragments of its forewing venation indicates it belongs to the Hesperiidae. Further reconstruction indicates that it fits in the Coeliadinae and is close to the extant genera Hasora and Burara. It is here described as Protocoeliades kristenseni gen. et sp. n. It is the first butterfly fossil found on a continent (Europe) where its closest relatives do not currently occur. Its position on the phylogenetic tree of the Coeliadinae and its importance in understanding the time dimension in the evolution of butterflies, and their ecological and biogeographic implications are discussed., Rienk De Jong., and Obsahuje bibliografii
