New and interesting records of Balkans Lepidoptera are detailed. Holoterpna pruinosata (Staudinger, 1897), recently known in Europe only from Crimea, was re-discovered in the Balkan Peninsula. Idaea sericeata (Hübner, 1813) is shown to be a part of the Balkan fauna. Pabulatrix pabulatricula (Brahm, 1791) is new for the Central Balkans. Two genera and four species are new and six species are reported for the second time for Albania. For Montenegro, one genus and four species are new and four species are recorded for the second time. One genus and four species are new for the Republic of North Macedonia. Three species are new and two are reported for the second time for Serbia. Four species are new to Bulgaria and 11 are reported for the second time. For many other species, third localities are reported for certain countries. For other species we report highest or lowest altitude localities and southernmost/easternmost points of their range. Data for some other interesting species from these countries and Greece are also presented, including new localities for species with poorly known distribution in the Balkan Peninsula and Balkans countries. Illustrations of specimens and their genitalia are given when necessary. Altogether data for 267 species of Lepidoptera are presented here, with 200 figures of habitats, specimens and their genitalia. In addition one Tachinidae (Diptera) parasitoid is new for Albania, and a new host species is reported for it.
