This work presents an updated catalogue of the Lepidoptera found in the Faroe Islands. It includes 170 species recorded between 1781 and 2023. For each species all relevant literature is listed, details of the first record are given, and the status as either resident, migrant or introduced (and perhaps naturalized) is stated. Details on biology are...

The genus Zizyphia and the species Z. cleodorella is diagnosed and its separation from the closely related Z. zizyphella Amsel, 1935 is elaborated. The adult habitus and genital structure, and the species’ habitat are illustrated. The systematic position of the genus is dis...

In this contribution, all together 121 Gelechiidae species are reported for the Croatian Island of Krk. Almost half, 61 species, were already covered in other publications. After the revision of published data from other authors and additional surveys, we were able to confirm additional 60 species for the island and add additional biogeographic dat...

A new species of Gnorimoschemini (Gelechiidae), Klimeschiopsis arnoldfransorum sp. nov., is described from specimens collected in Spain. The species is most closely related to Klimeschiopsis terroris (Hartig, 1938), with which it was hitherto mixed, but differs particularly by its small size with reduced yellowish-white forewing markings, the chara...

Thiotricha sumpichi sp. nov. is described from Greece and Croatia. The systematic position of the new species within Thiotricha is discussed based on external and genitalia characters and from DNA barcodes of the mitochondrial COI gene (cytochrome c oxidase 1).

The main purpose of this catalogue was to improve our knowledge of the Lepidoptera fauna of Iran and acquire a better knowledge of the patterns of distribution of this large insect order within the country. These patterns not only show the large-scale structure of the faunal elements of this order in Iran, but also highlight research gaps and and o...

The Azores is a remote oceanic archipelago of nine islands which belongs to the Macaronesia biogeographical region hosting a unique biodiversity. The present Azorean landscape is strongly modified by the presence of man and only in small areas, where the soil or climate was too rough, have primitive conditions remained unchanged. Despite the fact t...

We provide diagnostics for eight species groups of Oriental Pseudopostega Kozlov (Lepidoptera: Opostegidae) and a pictorial key for their identification. We designate three new species groups, P. frigida and P. strigulata groups, and the P. auritella group for two Palaearctic species, and rename the P. nigrimaculella group as the P. matrona group....

We describe and illustrate Anthophila variabilis Falck, Karsholt & Rota, sp. n. (Choreutidae) from Tenerife (Canary Islands, Spain). The new species is outstanding due to the variability of its male genitalia. It is closely related to A. fabriciana (Linnaeus, 1767), and more distantly related to Anthophila threnodes (Walsingham, 1910), which is end...

Monopis jussii Kaila, Mutanen, Huemer, Karsholt & Autto, sp. nov. (Lepidoptera, Tineidae) is described as a new species. It is closely related to the widespread and common M. laevigella ([Denis & Schiffermül-ler], 1775), but differs in its distinct COI DNA barcode sequences, four examined nuclear loci as well as details in forewing coloration and p...

Megacraspedus cottiensis sp. nov. is described from the western Alps (prov. Torino, Italy). The dorsal habitus and genitalia for both the male and brachypterous female are provided.

The identity of Gelechia sircomella Stainton, 1854, is considered. The two syntypes were destroyed by war action in 1940. The conclusion after consideration of the best available evidence is that it is merely a form of Aproaerema taeniolella (Zeller, 1839).

Spiniphallelus eberti sp. nov. (Iran) and Spiniphallellus naumanni sp. nov. (Afghanistan) are described. The position of the genus within the subfamily Anomologinae is briefly discussed, as is the degree of development of the gnathos in the male genitalia of two species within the same genus. A key to all Spiniphallellus species is given, and adult...

Sobre la base del reciente trabajo de campo, principalmente por el primer autor, registramos como nuevas las siguientes once especies de Microlepidoptara para las Islas Canarias: Prays peregrina Agassiz, 2007 (Praydidae); Epicallima mikkolai (Lvovsky, 1995) (Oecophoridae); Stathmopoda auriferella (Walker, 1864) (Stathmopodidae); Scythris albidella...

In a recent paper in ZooKeys, Wiemers et al. (2018) provided an updated list of European butterfly names. In this list the authors follow gender agreement for species names, when interpreted as adjectival in derivation, in contrast to the common practice among most lepidopterists. Here we comment on this aspect of the paper, and voice our concern t...
