Abstract
New founds of 4 species of East Asian Geometridae: Megabiston plumosaria (Leech, 1891), Photoscotosia lucicolens (Butler, 1878), Callabraxas fabiolaria (Oberthür, 1884), and Dysstroma cinereata (Moore, 1867) in the extreme southwest of the Russian Far East are presented and discussed due to the actual distribution and its current trends. From them Ph. lucicolens is recorded from Russia and China (Jilin) for the first time. Identity of specimens of "Photoscotosia atrostrigata" and "Dysstroma cinereata" in Barcode of Life Database is revised to Ph. lucicolens and Paradysstroma corussaria (Oberthür, 1880) respectively. These founds probably indicate northern expansion of ranges of geometrid moth in accordance with the current climatic trend of global warming. Potential harmfulness of M. plumosaria in RFE is assumed. The validity of Dysstroma cinerea cesa Koçak & Kemal, 2001, as a substitute name for Dysstroma cinereata japonica (Heydemann, 1929) is substantiated.
Highlights
The extreme southwest of the Russian Far East borders on North Korea and Northeast China
One more species is added to them, a new one for the Russia – Photoscotosia lucicolens (Butler, 1878); new and unpublished finds of C. fabiolaria, D. cinereata, and M. plumosaria are presented
Trends to penetration of southern moth into RFE start to be observed from registration on eSW RFE of Sphingidae – remarkable moths which hardly be loosed by insert collectors
Summary
The extreme southwest of the Russian Far East (hereinafter referred to as eSW RFE) borders on North Korea and Northeast China. It is located in the Khasanskii Rayon of the Primorskii Krai. Biota of the eSW RFE possesses many East Asian faunistic and floristic elements, common with Korea, Japan and China, which do not go north of this territory. In the flora, these are, for example, such prominent woody plants as Pinus densiflora, Betula schmidtii and Rhododendron schlippenbachii. Nomenclatural notes on Dysstroma cinereata japonica (Heydemann, 1929) and Dysstroma cinereata cesa Koçak & Kemal, 2001, are given, with regads to correct original combination of genus and same species names of Heydemann's nominal taxa
