New records of caddisflies of the genus Plectrocnemia Stephens, 1836 (Trichoptera: Polycentropodidae) from Siberia (Russia)

Abstract

Previously, caddisflies of the genus Plectrocnemia Stephens, 1836 were unknown in the fauna of Siberia. In May-October 2018 adult P. kusnezovi Martynov, 1934 and P. wui (Ulmer, 1932) were collected in the upper part of the Yenisei River basin (Republic of Khakassia, Abakan city, Abakan River valley) with a UV lamp. These records clarify the northern and western boundaries of their ranges. Distribution of P. kusnezovi and P. wui in Asia and flight periods in the region are given. A possible record of P. conspersa (Curtis, 1834) in Western Siberia is discussed; this species is known from the Ural Mountains, Southern Siberia (Salair Ridge) and Xinjiang-Uygur Autonomous Region of China.
