Remarks. Micropsectra atrofasciata is an eurytopic and one of the most common species within the genus and the tribe in Europe (Giłka 2011c), distributed across the Palaearctic region. The wide geographical range and distinct intraspecific variations in the body size and colouration, depending also on a generation (seasonal heteromorphism), as well as in the shape of some key structures of the hypopygium (cf. Giłka 2000, 2001a, 2011a; see also remarks to Micropsectra joganplumosa and Tanytarsus volgensis below), were probably the reason for multiple descriptions of this species under different names. A redefinition of M. atrofasciata by Stur and Ekrem (2006) includes eight junior synonyms. Here, we analyzed another name, Micropsectra tonewdeea Sasa et Tanaka, 2002, based on description of the adult male and photographs of the holotype displayed on the website of the NMNS (405:070). A comparison of diagnostic characters shows that the type specimen described for this name falls within the wide range of morphological variability of M. atrofasciata . As far as we know, the name, treated as synonymous here, has not been used apart from the original description based on materials from locus typicus in Gunma Prefecture, Honshu (Sasa & Tanaka 2002).
