TL;DR: A checklist of Gelechiidae in America north of Mexico is provided based on additions of new taxa and nomenclatorial changes in publications since 1978, which includes the addition of 253 new species and 8 new genera.
Abstract: A checklist of Gelechiidae in America north of Mexico is provided based on additions of new taxa and nomenclatorial changes in publications since 1978. This checklist includes the addition of 253 new species and 8 new genera, 30 species and 5 genera previously unrecorded from North America, 4 species inadvertently omitted in the previous checklist, and many nomenclatorial changes. Ymeldia Hodges, 1963 is transferred to Oecophoridae. The following new synonymies are established: Neoschema Povolny, 1967, n. syn. of Gnorimoschema Busck, 1900; Scrobipalpulopsis Povolný, 1987, n. syn. of Scrobipalpula Povolný; 1964, Tuta Kieffer & Jorgensen, 1910, rev. syn. of Phthorimaea Meyrick, 1902; Eupolella Fletcher, 1940, n. syn. of Dichomeris Hubner, [1818]; Eupolis Meyrick, 1923, n. syn. of Dichomeris Hubner, [1818]; Aristotelia nigrobasiella Clarke, 1932, n. syn. of Aristotelia isopelta Meyrick, 1929; Aristotelia intermediella (Chambers, 1879), n. syn. of Aristotelia pudibundella (Zeller, 1873); Gelechia brumella Clemens, 1864, n. syn. of Chionodes continuella (Zeller, 1839); Anacampsis bidiscomaculella (Chambers, 1874), rev. syn. of Anacampsis fullonella (Zeller, 1873); Aroga trachycosma (Meyrick, 1923), n. syn. of Aroga elaboratella (Braun, 1923); and Dichomeris caryaefoliella (Chambers, 1872), n. syn. of Dichomeris georgiella (Walker, 1866). The following new combinations are made: Monochroa pullusella (Chambers, 1874), n. comb., Monochroa robusta (Braun, 1921), n. comb., Gnorimoschema klotsi (Povolný, 1967), n. comb., Gnorimoschema powelli (Povolný, 1998a), n. comb., Scrobipalpuloides chiquitella (Busck, 1910), n. comb., Scrobipalpuloides chiquitelloides (Powell & Povolný, 2001), n. comb., Scrobipalpuloides elaborata (Povolný, 2000), n. comb., Scrobipalpuloides insularis (Powell & Povolný, 2001) n. comb., Scrobipalpuloides isolata (Povolný, 2000) n. comb., Scrobipalpuloides spinosa (Povolný, 2000), n. comb., Scrobipalpuloides totalis (Povolný, 2000), n. comb., Scrobipalpuloides truncata (Povolný, 2000), n. comb., Scrobipalpula lutescella (Clarke, 1934), n. comb., Scrobipalpula lycii (Powell & Povolný, 2001), n. comb., Scrobipalpula physaliella (Chambers, 1872), n. comb., and Scrobipalpa arenaceariella (Powell & Povolný, 2001), n. comb. New records for the Nearctic Region are given for Carpatolechia fugitivella (Zeller), Carpatolechia notatella (Hubner), Carpatolechia proximella (Hubner), and Altenia perspersella (Wocke). This checklist also provides the type localities of species based on examination of specimens and published references. Subfamilies have been divided into tribes, which has required rearrangement of genera. References that include new taxa or nomenclatorial changes since 1978 are provided.
TL;DR: In this paper, Biondi et al. presented the first attempt to classify T. absoluta among taxa of Gnorimoschemini using cladistic methodology.
Abstract: Tuta absoluta (Meyrick, 1917) is one of the most notorious pests of solanaceous plants in the World (Biondi et al. 2018), however, its supra-specific classification has been an historical point of contention. Its original genus, PhthorimaeaMeyrick, 1902, was a catch-all within the family and the generic limits among its contained tribe, Gnorimoschemini Povolný, 1964, are unstable. This study represents the first attempt to classify T. absoluta among taxa of Gnorimoschemini using cladistic methodology. We constructed a tree hypothesis based on 22 morphological characters using the nominal taxa for the genera Phthorimaea, ScrobipalpuloidesPovolný, 1987, and TutaKieffer and Jorgensen, 1910 among the ingroup; and the nominal taxon for the tribe Gnorimoschemini, Gnorimoschema gallaesolidaginis (Riley, 1869), as the outgroup. The parsimony analysis resulted in a single shortest tree with T. absoluta in a monophyletic clade that included Phthorimaea operculella (Zeller, 1873), the type species of Phthorimaea. The genera Tuta and Scrobipalpuloides were also resolved in the tree hypothesis. We propose the reinstated combination Phthorimaea absoluta Meyrick, 1917 and the new combination Phthorimaea chiquitella (Busck, 1910). The genera Tuta (with the single species Tuta atriplicellaKieffer and Jorgensen, 1910) and Scrobipalpuloides remain valid in Gnorimoschemini. We provide a history of the taxonomy of Tuta absoluta and a detailed character list and matrix used in our analysis.
