RESUMEN
First description of the hitherto unknown male of Cyana nigrilineata (Hampson, 1900) (Lepidoptera, Erebidae: Arctiinae) is presented. This species is similar to Cyana malayensis (Hampson, 1914) and C. barisana Roesler & Kppers, 1976 in external features and the structure of the male genitalia. These three species co-occur in Sumatra Island.

Global environmental changes may cause dramatic insect declines but over century-long time series of certain species' records are rarely available for scientific research. The Menetries' Tiger Moth (Arctia menetriesii) appears to be the most enigmatic example among boreal insects. Although it occurs throughout the entire Eurasian taiga biome, it is so rare that less than 100 specimens were recorded since its original description in 1846. Here, we present the database, which contains nearly all available information on the species' records collected from 1840s to 2020. The data on A. menetriesii records (N = 78) through geographic regions, environments, and different timeframes are compiled and unified. The database may serve as the basis for a wide array of future research such as the distribution modeling and predictions of range shifts under climate changes. It represents a unique example of a more than century-long dataset of distributional, ecological, and phenological data designed for an exceptionally rare but widespread boreal insect, which primarily occurs in hard-to-reach, uninhabited areas of Eurasia.

Victrix svetlanae sp. n. is described from Russian Far East, Khabarovsk Krai. The new species belongs to the subgenus Poliobrya Hampson, 1908. New species is most similar to V. umovii (Eversmann, 1846) and V. patula (Püngeler, 1907) but differs in both external and genital characteristics. This is the first record of the genus Victrix in the Far East.
