Records of mining Lepidoptera in Belgium with nine species new to the country (Nepticulidae, Opostegidae, Tischeriidae, Lyonetiidae)

Abstract. Records of 56 species of mining Lepidoptera are given, mostly for Wallonia. Stigmella thuringiaca (Namur: Nismes, on Potentilla tabernaemontani), Ectoedemia arcuatella (Luxembourg, Namur, on Fragaria vesca) and Leucoptera lustratella (Luxembourg, Namur, on Hypericum perforatum) are reported new for Belgium on the basis of reared adults, Stigmella crataegella (Luxembourg: Belvaux, Crataegus monogyna), S. confusella (West Vlaanderen, Betula pubescens), Trifurcula subnitidella (Namur: Nismes, Lotus corniculatus), and Ectoedemia spinosella (Namur: Nismes, Prunus spinosa) are reported as new on the basis of vacated mines and Coptotriche heinemanni (on Agrimonia eupatoria) and C. gaunacella (on Prunus spinosa) are reported as new both from the province of Luxembourg: Torgny, each on the basis of a single larva and mine, of which rearing failed. In addition to these, 50 new provincial records are given, particularly for Liège, Luxembourg and Namur. The previous record of Ectoedemia agrimoniae is regarded to be in the province of Luxembourg, not Namur.
