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).
