BengtA.Bengtsson,Lokeg.3,S-38693Farjestaden,[email protected] Introduction The photographs (about 10) were processed by the software Helicon Focus Version 4.2.8 (10871). The TheEuropeanfaunaofthemicrolepidopterousfamily genitalia illustrationswereproduced inasimilarmanner Scythrididae is comparatively well explored and only a withmulti-layertechnique,usingthesamecameraanda few new species have been found and described after Euromex EB compound Microscope with a plan lens the review of the West Palaearctic Scythrididae by 5/0.18. Bengtsson (1997). An interesting exception from this is the number of new species that have been described fromthemosteasterlypartsofEuropeinorclosetothe Ural Mountains,andfrom NorthAfricaandTurkey,from where more than twenty new species have been described (e.g. Nupponen 1999, 2003, 2004, 2005a, 2005b, 2007, 2009, 2010; Nupponen et al. 2003; and Nupponenetal.2000). During2011OleKarsholtatZMUC,Copenhagen,sent meadamagedscythrididspecimen,collectedbyL.Srnka, with itsgenitalia in a plastictube.
