TL;DR: The 25 genera of Teleiodini (Lepidoptera: Gelechiidae) occurring in the Holarctic Region are revised and a new genus and new species, Arcutelphusa talladega, are described from Alabama and Mississippi, United States.
Abstract: The 25 genera of Teleiodini (Lepidoptera: Gelechiidae) occurring in the Holarctic Region are revised. A new genus and new species, Arcutelphusa talladega, are described from Alabama and Mississippi, United States. Evippe Chambers (1873a) is synonymized with Agnippe Chambers (1872a), Hapalosaris Meyrick (1917) is synonymized with Coleotechnites Chambers (1880b), and Laris Omelko (1988) is synonymized with Parastenolechia Kanazawa (1985). Telphusa is restricted to three species, and Teleiodes is restricted to four species. A key to genera and a checklist of species, which includes 28 new combinations, are provided. Each generic treatment includes descriptions of imagos, including venation and genitalia, and immature stages so far as known, larval hosts, diversity and distribution, and illustrations of selected species.
TL;DR: Pubitelphusa is proposed as a new genus for Gelechia latifasciella Chambers in North America and Concubina trigonalis Park and Ponomarenko in the Palearctic Region.
Abstract: . Pubitelphusa is proposed as a new genus for Gelechia latifasciella Chambers in North America and Concubina trigonalis Park and Ponomarenko in the Palearctic Region. Pubitelphusa latifasciella, most recently assigned to Telphusa, is redescribed, and male and female genitalia are illustrated. A neotype for G. latifasciella is designated. Concubina trigonalis is transferred to Pubitelphusa.
TL;DR: Two new species of the family Gelechiidae, Concubina trigonalis Park and Ponomarenko, n.
Abstract: Two new species of the family Gelechiidae, Concubina trigonalis Park and Ponomarenko, n. sp. and Teleiodes gangwonensis Park and Ponomarenko, n. sp. are described from Korea. Telphusa euryzeucta Meyrick, 1922, is transferred to Concubina: Concubina euryzeucta (Meyrick 1922), n. comb. Concubina subita N. Omelko and M. Omelko, 2004 is considered a new junior synonym of C. euryzeucta.
