First records of species of Gelechioidae from Bitterfeld amber (Insecta, Lepidoptera) and notes on two gelechioid species from Baltic amber

Research on Lepidoptera from the Bitterfeld amber is still in a very early stage. The superfamily Gelechioidea is here recorded for the first time from this deposit. Descriptions of male individuals of two species are provided including parts of their external genitalia. The fossils differ from extant representatives of European Gelechioidea by several characters which justify the establishment of two new genera: Barthelius pumilus gen. et sp. nov. (family incertae sedis) and Krutzschius nanarius gen. et sp. nov. (family incertae sedis). The reasons of the unresolved family affiliation of both taxa are shortly discussed. Descriptions of males of two gelechioid species from Baltic amber, Symmoca hoffeinsorum sp. nov. and Oegoconites rohdendorfi Kusnetzov, 1941 provide additional taxonomic and biogeographical background.
