Tanytarsus volgensis Miseiko, 1967: Ekrem 2004: 139 (male, figs 194–202; = fimbriatus Reiss et Fittkau, 1971); Giłka & Paasivirta 2007: 107–109 (male, figs 7–9, 12, 14).
Material examined. Hwangju, 18–19 June 1981, 7 males ; Kaesŏng, 16 July 1981, 1 male ; Phjŏngjang, 11 June 1981, 27 males ; 13 June 1981, 28 males; 18 July 1981, 26 males; Sariwŏn, 18 June 1981, 5 males ; Sokam, 8 July 1981, 29 males; leg. W. Krzemiński.
Remarks. This eurytopic and widespread Holarctic species (cf. Giłka 2011c) was found as the most frequent and abundant tanytarsine in North Korea - recorded from two sites by Reiss (1980, as T. fimbriatus) and now confirmed at further 5 localities (123 males = over 55% of all examined specimens). Interestingly, an extremely wide range of the body size and colouration have been observed in the examined males, among which the biggest specimens, darker are nearly twice as long as the smallest ones, lighter (see also remarks to Micropsectra atrofasciata and M. joganplumosa).
