Remarks. Ivinskis & Piskunov (1980) introduced a new genus Ivanauskiella and described I. turkmenica Ivinskis & Piskunov, 1980 as its type species. Later I. turkmenica was synonymized with I. psamathias ( Piskunov 1990b) . The female genitalia of I. psamathias published by Bidzilya et al. (1998) are incorrect and belong to another species, possibly M. nomadella (Zeller, 1868) (see above). Habitually I. psamathias resembles M. nomadella , but the adult is smaller in size and forewings and thorax are more lustrous. A description of the female genitalia is given below. It is new to the European part of Russia.

Female genitalia (Figs. 24–25). Antrum funnel-shaped, posteriorly broader. Colliculum with broad sclerotized plate. Ductus bursae simple, membranous tube, gradually widening towards corpus bursae. Corpus bursae asymmetrical sack with two separate signa, larger one horned, and smaller one roundish plate with ragged margins. Apophyses anteriores 0.8x length of apophyses posteriores.

Distribution. Bulgaria, Russia (S Ural, Volga-Don region), Ukraine ( Bidzilya 1997). Outside Europe in S Siberia, Mongolia, Turkmenistan and N Africa.
