Taxonomic status and molecular phylogeography of two sibling species of Polytremis (Lepidoptera: Hesperiidae).

ABSTRACT: The skipper Polytremis theca species complex is widely distributed in the south of the Qinling Mountains in China. A recent study of the Polytremis genus suggested that this species might encompass two differentiated lineages. We tested this hypothesis, by carrying out a phylogenetic study of this agricultural pest based on nationwide sampling and the evaluation of mitochondrial and nuclear DNA markers. We show that this species is actually an amalgamation of two sibling taxa (P. t. theca and P. t. fukia), which displayed levels of genetic divergence as great as those generally found between sister species in the Polytremis genus, suggesting that they actually correspond to two distinct species. The Divergence time estimates suggest that an active period of speciation within Polytremis occurred within the Pleistocene eras. Based on its distinct phylogenetic placement and geographical isolation, we suggest that the subspecies should be elevated to full species status under the phylogenetic species concept, which has significant management implications.

Project description:Analyses of whole genomic shotgun datasets, COI barcodes, morphology, and historical literature suggest that the following 13 butterfly species from the family Hesperiidae (Lepidoptera: Papilionoidea) in Texas, USA are distinct from their closest named relatives and therefore are described as new (type localities are given in parenthesis): Spicauda atelis Grishin, new species (Hidalgo Co., Mission), Urbanus (Urbanus) rickardi Grishin, new species (Hidalgo Co., nr. Madero), Urbanus (Urbanus) oplerorum Grishin, new species (Hidalgo Co., Mission/Madero), Telegonus tsongae Grishin, new species (Starr Co., Roma), Autochton caballo Grishin, new species (Hidalgo Co., 6 mi W of Hidalgo), Epargyreus fractigutta Grishin, new species (Hidalgo Co., McAllen), Aguna mcguirei Grishin, new species (Cameron Co., Brownsville), Polygonus pardus Grishin, new species (Hidalgo Co., McAllen), Arteurotia artistella Grishin, new species (Hidalgo Co., Mission), Heliopetes elonmuski Grishin, new species (Cameron Co., Boca Chica), Hesperia balcones Grishin, new species (Travis Co., Volente), Troyus fabulosus Grishin, new species (Hidalgo Co., Peñitas), and Lerema ochrius Grishin, new species (Hidalgo Co., nr. Relampago). Most of these species are known in the US almost exclusively from the Lower Rio Grande Valley in Texas. Nine of the holotypes were collected in 1971-1975, a banner period for butterfly species newly recorded from the Rio Grande Valley of Texas; five of them collected by William W. McGuire, and one by Nadine M. McGuire. At the time, these new species have been recorded under the names of their close relatives. A Neotype is designated for Papilio fulminator Sepp, [1841] (Suriname). Lectotypes are designated for Goniurus teleus Hübner, 1821 (unknown, likely in South America), Goniloba azul Reakirt, [1867] (Mexico: Veracruz) and Eudamus misitra Plötz, 1881 (Mexico). Several taxonomic changes are proposed. The following taxa are species (not subspecies): Spicauda zalanthus (Plötz, 1880), reinstated status (not Spicauda teleus (Hübner, 1821)), Telegonus fulminator (Sepp, [1841]), reinstated status (not Telegonus fulgerator (Walch, 1775), Telegonus misitra (Plötz, 1881), reinstated status (not Telegonus azul (Reakirt, [1867])), Autochton reducta (Mabille and Boullet, 1919), new status (not Autochton potrillo (Lucas, 1857)), Epargyreus gaumeri Godman and Salvin, 1893, reinstated status (not Epargyreus clavicornis (Herrich-Schäffer, 1869)), and Polygonus punctus E. Bell and W. Comstock, 1948, new status (not Polygonus savigny (Latreille, [1824])). Urbanus ehakernae Burns, 2014 and Epargyreus socus chota Evans, 1952 are junior subjective synonyms of Urbanus alva Evans, 1952 and Epargyreus clavicornis (Herrich-Schäffer, 1869), respectively, and Epargyreus gaumeri tenda Evans, 1955, new combination is not a subspecies of E. clavicornis.

Project description:Genomic sequencing and analysis of worldwide skipper butterfly (Lepidoptera: Hesperiidae) fauna points to imperfections in their current classification. Some tribes, subtribes and genera as they are circumscribed today are not monophyletic. Rationalizing genomic results from the perspective of phenotypic characters suggests two new tribes, two new subtribes and 50 new genera that are named here: Ceratrichiini Grishin, trib. n., Gretnini Grishin, trib. n., Falgina Grishin, subtr. n., Apaustina Grishin, subtr. n., Flattoides Grishin, gen. n., Aurivittia Grishin, gen. n., Viuria Grishin, gen. n., Clytius Grishin, gen. n., Incisus Grishin, gen. n., Perus Grishin, gen. n., Livida Grishin, gen. n., Festivia Grishin, gen. n., Hoodus Grishin, gen. n., Anaxas Grishin, gen. n., Chiothion Grishin, gen. n., Crenda Grishin, gen. n., Santa Grishin, gen. n., Canesia Grishin, gen. n., Bralus Grishin, gen. n., Ladda Grishin, gen. n., Willema Grishin, gen. n., Argemma Grishin, gen. n., Nervia Grishin, gen. n., Dotta Grishin, gen. n., Lissia Grishin, gen. n., Xanthonymus Grishin, gen. n., Cerba Grishin, gen. n., Avestia Grishin, gen. n., Zetka Grishin, gen. n., Turmosa Grishin, gen. n., Mielkeus Grishin, gen. n., Coolus Grishin, gen. n., Daron Grishin, gen. n., Barrolla Grishin, gen. n., Brownus Grishin, gen. n., Tava Grishin, gen. n., Rigga Grishin, gen. n., Haza Grishin, gen. n., Dubia Grishin, gen. n., Pares Grishin, gen. n., Chitta Grishin, gen. n., Artonia Grishin, gen. n., Lurida Grishin, gen. n., Corra Grishin, gen. n., Fidius Grishin, gen. n., Veadda Grishin, gen. n., Tricrista Grishin, gen. n., Viridina Grishin, gen. n., Alychna Grishin, gen. n., Ralis Grishin, gen. n., Testia Grishin, gen. n., Buzella Grishin, gen. n., Vernia Grishin, gen. n., and Lon Grishin, gen. n. In addition, the following taxonomic changes are suggested. Prada Evans is transferred from Hesperiinae to Trapezitinae. Echelatus Godman and Salvin, Systaspes Weeks, and Oenides Mabille are removed from synonymy and are treated as valid genera. The following genera are new junior subjective synonyms: Tosta Evans of Eantis Boisduval; Turmada Evans of Neoxeniades Hayward, Arita Evans of Tigasis Godman, and Alera Mabille of Perichares Scudder. Eantis pallida (R. Felder) (not Achlyodes Hübner), Gindanes kelso (Evans) (not Onenses Godman and Salvin), Isoteinon abjecta (Snellen) (not Astictopterus C. and R. Felder), Neoxeniades ethoda (Hewitson) (not Xeniades Godman), Moeris anna (Mabille) (not Vidius Evans), and Molo pelta Evans (not Lychnuchus Hübner) are new genus-species combinations. The following are species-level taxa: Livida assecla (Mabille) (not a subspecies of Livida grandis (Mabille), formerly Pythonides Hübner) and Alychna zenus (E. Bell) (not a junior subjective synonym of Alychna exclamationis (Mabille), formerly Psoralis Mabille); and Barrolla molla E. Bell (formerly Vacerra Godman) is a junior subjective synonym of Barrolla barroni Evans (formerly Paratrytone Godman). All these changes to taxonomic status of names are propagated to all names currently treated as subspecies (for species), subgenera (for genera) and synonyms of these taxa. Finally, taxa not mentioned in this work are considered to remain at the ranks and in taxonomic groups they have been previously assigned to.
