Remarks. This species was known only from the Alborz of Iran , where it is a widespread summer and autumnal emerging stonefly ( Aubert 1964 , Theischinger 1976 ). This peculiar species shares an isolated position within the genus Nemoura , together with N. persica Zwick, 1980 (also endemic to the Alborz ) and N. monae Joost, 1977 (known from the Greater Caucasus (Krasnodar Krai) and the Lesser Caucasus ( Georgia ) – Zhiltzova 2003). In Azerbaijan , we collected the species both in the northeast (Gəncə-Qazax region) and the southwest ( Naxçıvan ) of the Lesser Caucasus. It was found in single or few specimens at high elevation seeps covered by tall sedges and other herbs. New for the fauna of Azerbaijan , and the whole of the Caucasian region.
