| Summary: | Timandra rectistrigaria (Eversmann) (Fig. 57) Timandra rectistrigaria : Beljaev & Mironov 2019: 281 (Sakhalin). Material examined. 2 ♂, Zhitnitsa river, 1.VII.2003. Distribution. Russia (RFE: central Sakhalin, Kamchatka Peninsula, Magadanskaya Oblast, Khabarovskii Krai, Amurskaya Oblast, Primorskii Krai—middle and?northern Sikhote-Alin range; S Yakutia, S and W Siberia, Polar Urals). Remarks. The finding of T. rectistrigaria in Sakhalin significantly expands its distribution range to the east. Same as I. pallidata , in Sakhalin this species was found in a zone of the dominance of spruce-fir forests. T. rectistrigaria is an arctic-boreal trans-Siberian species, associated mainly with the specific Siberian larch swamps with thickets of Lonicera caerulea and various Vaccinium species. This species, together with Holarctias rufinaria (Staudinger), are endemic Siberan “Angarian” species, the presence of which in Sakhalin indicates the historical zoogeographic connections of the island with Eastern Siberia during the Pleistocene cooling era. In the continental RFE, the southernmost location of T. rectistrigaria on the Kolumbe river in the central Primorskii Krai was reported by Kurentzov (1937: 120). Due to the absence of other reports of this species south of the Amur river, this reference has been questioned (Beljaev & Mironov 2019). Fortunately, the original specimen collected by Kurentzov was recently found in the entomological collection of the FSC EATB, labelled as: “Kolumbe river, mixed valley taiga, 28.VI [19]34”—Primorskii Krai, Krasnoarmeiskii district, ~ 6 km E of Melnichnoe village, near the mouth of the Kolumbe river ~ 45°23’ N, 135°39’ E. This is the most southeastern confirmed locality for this species.An indication of T. rectistrigaria from the Kedrovaya Pad Nature Reserve (extreme southwest of Primorskii Krai, ~ 43° N) (Kurina 2022j) is highly doubtful, as the environment of this site—broadleaf and mixed forests with southern coniferous trees—is completely different from the characteristic ... |
