Material and Methods (Huemer & Karsholt 2020) and their DNA barcode library (Huemer et al. 2020). In Romania the study of the Gelechiidae was neglected for a very long time, in the majority of the publications only a few data were provided, mainly as part of regional faunistic studies (e.g. Mann 1866; Rebel 1911; Popescu-Gorj & Drághia 1964, 1967, 1968; Wieser et al. 2000), catalogues of collections (e.g. Popescu-Gorj 1964; Nemeș & Danila 1970; König 1975; Kovács & Kovács 2001), and rarely records of species (e.g. Nemeș 1968; Popescu-Gorj 1985a; Kovács & Kovács 1994, 2002a, 2002b). Their number in the checklists reflect the degree of their knowledge: 61 in Caradja (1899), 74 in Caradja (1901), both which refer to Dobrogea, Muntenia, Moldova and Oltenia, and 174 in Czekelius (1918) referring to Banat, Crișana and Transylvania. The first recent attempt to gather all published data was the work of Popescu-Gorj (1984), as part of the checklist of the Romanian Microlepidoptera. Unfortunately it was only a simple list comprising 176 Gelechiidae species. The first critical reassessment of the Gelechiidae fauna in Romania (Kovács & Kovács 2000) became possible only after the publication of the European revisions cited in the first paragraph, it was based on the combination of an overview of the literature together with the study of the material in the L. Diószeghy collection (deposited in the Székely National Museum in Sfântu Gheorghe) and of the authors’ collection, which resulted in the identification of 239 species. The previously mentioned study was also the basis of the Gelechiidae family in the last two checklists of the Romanian Lepidoptera by Rákosy et al. (2003), giving 250 species, and Rákosy & Goia (2021), comprising 260 species. Over the last two decades an important amount of gelechiid material was collected by the authors, several new studies were published on a continental level (see above) and significant changes have taken place in the systematics of the family (Karsholt et al. 2013, Huemer & Karsholt 2020), however, the latter were not reflected in the latest Romanian checklist (Rákosy & Goia 2021), all these factors justifying the reassessment of the Romanian Gelechiidae fauna.

To compile this owerview we examined a rich material of more than 9,600 Romanian specimens of the Gelechiidae. The overwhelming majority came from our own collection together with the material in the L. Diószeghy collection deposited in the Székely National Museum of Sfântu Gheorghe. Additionally, a few specimens from the collections of M. Brătășeanu (deposited in the Museum of Brașov), V. Albu, V. Dincă, L. Rákosy and the late V. Vicol were also studied. Some data were kindly provided by M. Stănescu (curator at MGAB), Zs. Bálint and G. Katona (curators at HNHM). The genitalia of almost every species were examined. If the identification based on external characters alone was difficult, e.g. in specimens belonging to the genera Aproaerema and Scrobipalpa, we made as many genitalia preparations as necessary to identify all of the specimens. In the case of 13 species DNA barcode sequences of the mitochondrial COI gene were also obtained. Identification was usually made by the authors, but a couple of species were determined or confirmed by O. Karsholt, P. Huemer and Z. Tokár, all these are mentioned in the annotations. The data obtained were combined with the results of a critical re-evaluation of the literature. Included in the checklist are 7 species which remain unidentified and are probably undescribed taxa. Invasive species are also included. The systematic list follows the higher classification proposed by Karsholt et al. (2013), at generic and at specific level we follow the European checklist of Gelechiidae (Huemer & Karsholt 2020). Synonyms are not provided as they are listed in that checklist. An annotation was compiled of all listed taxa summarizing the current knowledge: the general distribution based on literature; occasionally also host-plant data; a summary of the most important literature data for the Romanian distribution, including, if possible, the first record; and a concise list of recent collecting sites based mainly on the examined material, but occasionally also on the latest publications. The regional division of the country follows Rákosy & Goia (2021: 6-7), but we reduced their number from 8 to 7 by disregarding the very small and very heterogeneous region Maramureș and Satu Mare (MM SM) and unifying Maramureș with Transylvania and Satu Mare with Crișana, in view of the natural zoogeographical connections. Detailed data are given only in the case of the first Romanian or regional records, and of a few rarely recorded species. The habitats and collecting methods are mentioned, but concise data about their biology are only exceptionally given. The occurrence of those species for which no voucher material has been examined is considered uncertain and in need of confirmation. Following the traditions in the case of the first Romanian records and confirmed species, figures of the adults and/or genitalia are provided. The genitalia 2
