### Introduction

The study of Elachistidae in Ukraine goes back more than 150 years. NOWICKI (1860) was the first who mentioned 16 species of grass-mining moths in his fundamental “Enumeratio Lepidopterorum Haliciae orientalis” devoted to the Lepidoptera of eastern “Halicia” (now Lvov region). Three additional species were recorded from this region five years later (NOWICKI, 1865). This outstanding beginning was carried on by the next generation of Polish lepidopterists in the first third of XX century. KLEMENCIEWICZ (1898, 1899, 1901, 1902, 1905, 1906, 1907), GATNAR (1906), STÖKL (1908, 1922), BRUNICKI (1913) contributed greatly to the study of all groups of Lepidoptera, and Elachistidae among them, in the territories of present Lvov and Ivano-Fankovsk regions mainly. At the same time HORMUZAKI (1907, 1910) published two important papers on Microlepidoptera of Bukowina, mentioning seven Elachistidae species from Tchernovtsy region. KHRANEVICH (1927) reported one species from Khmelnitsky region. Nearly all the faunistic information obtained by these authors was summarized in a monograph “Fauna motyli Polski” by SHILLE (1930). As a result the number of Elachistidae species known by 1930 from the western Ukraine was 37. Shille’s monograph remains the most complete compilation on Lepidoptera of the western Ukraine up to now.

In the beginning of the XX century the first records of Elachistidae were taken from others regions. KSENZHOPOLSKY (1915) recorded one species from the vicinity of Zhitomir. LJUBOMUDROV (1917) and ZHIKHAREV (1928) found one species in Kiev. Later LEBEDEV (1937) and SOVINSKY (1938) listed four and five species of Elachistidae respectively for Kiev in their contributions to the Microlepidoptera fauna of Kiev region.

Incredible but true: more than 40 years passed before the study of Microlepidoptera (incl. Elachistidae) in Ukraine was recommenced. In 1981-1989 the late A. Zagulajev organized a series of collecting trips to the Crimea. It was the beginning of the integrated study of all families of micromoths in this region. In 1983 this initiative was taken up by Yu. Budashkin, who started the permanent twelvemonth study of diversity and ecology of Lepidoptera in Crimea. Concerning Elachistidae this work has yielded a first contribution directly devoted to the grass-mining moths of Ukraine (BUDASHKIN & SINEV, 1991). In this paper, the authors compiled all known data on Elachistidae from the Crimea at that time. As a result a list of 24 species was provided for Karadagh Nature Reserve, and four species were described as new, two of which are now considered valid.

Since 1990, O. Bidzilya and A. Zhakov have been studying the Elachistidae mainly in the steppes regions of Ukrainian mainland. Kamennye Mogily Nature Reserve (Zaporozhie and Donetsk regions) was one of the first localities that has been intensively studied. The summarized list of Lepidoptera of this Nature Reserve includes nine species of grass-minning moths (BIDZILYA et al., 2001). In the mean-time 28 Elachistid species from the steppe zone and other regions have been mentioned in the series of faunistic papers (BIDZILYA, 1995, BIDZILYA & BUDASHKIN, 1998, BIDZILYA et al., 2003, 2006).

The current study of Elachistidae is part of an ongoing project on prepearing “The Catalogue of Lepidoptera of the Ukraine”. During the work on this first compilation on Ukrainian Lepidoptera we revised all data already published, studied additional materials from the collections of the Schmalhausen Institute of Zoology (Academy of Sciences of Ukraine), Kiev National Taras Shevchenko University and Karadagh Nature Reserve. We also critically checked all literature sources which deal with Elachsitidae from Ukraine. It turned out to be especially urgent due to the fact that the taxonomy of Elachistidae changed considerable over the last two decades. A number of new species have been described, several groups of closely related species have been revised, some species have been recognized as “species complexes” based on the study of type materials, etc. (KAILA et al., 2001, KAILA & JUNNILAINEN, 2002, KAILA et al., 2003, SUGISIMA, 2005, KAILA, 2007, 2009, 2011, 2012).

The main aim of the present paper is to provide the final list of Ukrainian grass-mining moths updated in accordance to the latest changes in taxonomy and nomenclature of the family. The system of Elachistidae in the present list follows KAILA (1999) except for Dibrachia Sinev & Sruoga, 1992, Biselachista Traugott-Olsen & Nielsen, 1977 and Cosmiotes Clemens, 1860 that we treat as separate genera according to SINEV (2008). The sections on “Distribution” are arranged geographical from northwest to south-east and countries referred to by their current names. The doubtful records are mentioned with “(?)”.

#### List of species

Perittia farinella (Thunberg, 1794) Distribution: Northern and Central Europe, Russia (North-Western of the European Part) (PARENTI, 1996, SINEV, 2008). In Ukraine it is known from Ivano-Frankovsk region (BIDZILYA et al., 2006).

Perittia herrichiella (Herrich-Schäffer, 1855) Distribution: Northern and Central Europe, Russia (Southern Ural) (PARENTI, 1996, KAILA et al., 2003, SINEV, 2008). In Ukraine is known only from Lvov region (KLEMENCIEWICZ, 1905, 1906, SCHILLE, 1930).

Perittia weberella Whitebread, 1984 Distribution: Switzerland, Russia (Southern Ural) (WHITEBREAD, 1984, PARENTI, 1996, KAILA et al., 2003, as sibirica Sin.). In Ukraine it is known only from the Donetsk reg. (BIDZILYA & BUDASHKIN, 1998).Notes: The species was erroneously recorded from the Southern Ural as Perittia sibirica Sinev, 1992 (KAILA et al., 2003). Later this record was mentioned in the “Catalogue of the Lepidoptera of Russia” (SINEV, 2008). P. sibirica is known only from the Irkutsk region (SINEV, 1992, SINEV & SRUOGA, 1997, SINEV, 2008) and must be removed from the European fauna.

Perittia karadaghella Sinev & Budashkin, 1991 Distribution: Crimea, Asia Minor (BUDASHKIN & SINEV, 1991, KAILA, 2009). In Ukraine it is known only from Crimea (Karadagh Nature Reserve) (BUDASHKIN & SINEV, 1991, BUDASHKIN, 2004).

Stephensia brunnichella (Linnaeus, 1767) Material examined: 1♀, Crimea, Dobroe, Krasnolesie, forest road, 11-13, 20-IV-1989 (Zagulajev).

In Ukraine it was known from Lvov and Ternopol regions as well as from Crimea (KLEMENCIEWICZ, 1898, STÖKL,1922, SCHILLE, 1930, BUDASHKIN & SINEV, 1991).

Dibrachia kalki (Parenti, 1978) Distribution: Germany, Austria (?), Italy, Slovakia, Hungary, Russia (Middle and Lower Volga, Southern Ural, Tuva), Kazakhstan (PARENTI, 1978, SINEV & SRUOGA, 1992, PARENTI, 1996, HUEMER, 2000, KAILA et al., 2003, SINEV, 2008, HUEMER, 2013). In Ukraine was known only from Donetsk region (BIDZILYA & BUDASHKIN, 1998).

In Ukraine it was known only from Lvov región (NOWICKI, 1860). Notes: The Elachista regificella-complex comprises three closely related and possible sympatrically distributed species: E. regificella Sircom, 1849, E. tengstromi Kaila, Bengtsson, Sˇulcs & Junnilainen, 2001 and E. geminatella (Herrich-Schäffer, 1855) (KAILA et al., 2001). As a result of the re-examination of the above cited specimen of “E. regificella” we found out that it actually referred to E. geminatella, whereas E. regificella must be removed from the fauna of Ukraine (BIDZILYA et al.,2006). It is unclear which species from this complex is referred to in the “Catalogue of the Lepidoptera of Russia” (SINEV, 2008).

In the original description the species is compared with E. pullicomella. However, as far as one can judge from the rather unclear photographs of adult and the genitalia, the habitus, phallus, valva and other characters of E. volgella are indistinguishable from those of E. littoricola. We therefore synonymyze it with the latter.
