First records of Palaearctic Agromyzidae (Diptera) from 40 countries and major islands

First records of 151 species in the family Agromyzidae are presented for 40 countries and major islands in the Palaearctic Region (Russia being split into four subregions): from Afghanistan (1 sp.), Albania (15 spp.), Algeria (1 sp.), Andorra (2 spp.), Armenia (4 spp.), Austria (14 spp.), Balearic Islands (4 spp.), Canary Islands (2 spp.), China - Palaearctic part (2 spp.), Corsica (5 spp.), Crete (6 spp.), Croatia (16 spp.), Czech Republic (4 spp.), Dodekanese Islands incl. Rhodes (5 spp.), Egypt (1 sp.), European Russia (2 spp.), Finland (12 spp.), France (1 sp.), Georgia (1 sp.), Germany (14 spp.), Great Britain (2 spp.), Greece (4 spp.), Iceland (1 sp.), Iran (8 spp.), Israel (1 sp.), Italy (12 spp.), Jordan (6 spp.), Kyrgyzstan (6 spp.), Lithuania (2 spp.), Macedonia (2 spp.), Mongolia (2 spp.), Morocco (6 spp.), Netherlands (1 sp.), Norway (3 spp.), Oman (1 sp.), Poland (1 sp.), West Siberia (1 sp.), East Sibiria (3 spp.), Kamchatka (5 spp.), Sardinia (1 sp.), Slovakia (4 spp.), South Korea (13 spp.), Spain (10 spp.), Sweden (7 spp.), Switzerland (5 spp.) and Turkey (1 sp.). For a few species morphological details or plant genera from the collecting localities are added as possible host plants. Phytomyza parvicella (Coquillett, 1902) exhibits an extremely disjunct distribution, occurring in the high Arctic from Alaska to west Greenland and on the highest mountains of Germany and Poland. Other rare species with Boreo-alpine disjunctions are recorded. Cerodontha (Cerodontha) phragmitophila Hering, 1935 reached a tiny artificial patch of its host plant within the Sahara sand desert. The thermophilic mediterranean Phytoliriomyza pectoralis (Becker, 1908) was detected on the Swedish sun-blessed island Öland. Chromatomyia obscuriceps (Hendel, 1936) (emerged from Triticum crop) is specified as a valid species occurring from Iceland to Kamchatka. A new definition for Chromatomyia nigra (Meigen, 1830) sensu stricto is presented. The American Amauromyza (Cephalomyza) abnormalis (Malloch, 1913), a possible agent against the harmful neophyte Amaranthus retroflexus, was detected for the first time in the Palaearctic Region. Gnaphalium is attributed as a first detected host plant genus of Phytoliriomyza venustula Spencer, 1976.
