Megacraspedus cottiensissp. 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 new species belongs to the M. faunierensis species group based on genitalia morphology and DNA barcodes, and was hitherto confused with M. neli Huemer & Karsholt, 2018 from the southwestern Alps. However, it clearly differs in morphology and DNA barcode sequences from that species and from M. faunierensis Huemer & Karsholt, 2018. The new species is suspected of being a regional endemic of the Cottian Alps.

AbstractBy means of an integrative taxonomic approach using morphology and DNA barcodes, multiple cryptic species within Lasioglossum (Dialictus) petrellum (Cockerell) (Hymenoptera: Halictidae) were discovered. Analysis of DNA barcode sequence data from across the supposed range of L. petrellum revealed distinct genetic differences that correlate with patterns of morphological variation and geographical distribution. The most morphologically distinct pair of species had the smallest DNA-barcode gap. The taxonomic limits of L. petrellum are revised and four new species are described and illustrated: L. (D.) tuolumnensesp. nov., L. (D.) griswoldisp. nov.L. (D.) droegeisp. nov., and L. (D.) viridipetrellumsp. nov. A key to species of the “L. petrellum” group is provided.

An integrative taxonomic analysis of the European species of theAgrotisfatidicaspecies-group is presented with special reference to the European sister taxa ofA.fatidica(Hübner, 1824); in addition, a general overview of the entire species-group is given. The remarkable differences found in the barcodes of the Central and Western European populations ofA.fatidica(sensu lato) led us to recognise isolated species of theA.fatidicacomplex. Two new species,A.mayrorumsp. n.(Northern Italy and the French Alps) andA.mazelisp. n.(French Pyrenees) are described. The neotype ofA.fatidicais designated.Agrotisluehrivon Mentzer & Moberg, 1987 is treated as a subspecies ofA.fatidica(stat. n.).

Taxonomic Approach

The taxonomy of the Palearctic genusMegacraspedusZeller, 1839 (Lepidoptera, Gelechiidae) is revised, based on external morphology, genitalia and DNA barcodes. An integrative taxonomic approach supports the existence of 85 species which are arranged in 24 species groups (disputed taxa from other faunal regions are discussed). Morphology of all species is described and figured in detail. For 35 species both sexes are described; for 46 species only the male sex is reported, in one species the male is unknown, whereas in three species the female adult and/or genitalia morphology could not be analysed due to lack of material.DNA barcode sequences of the COI barcode fragment with > 500 bp were obtained from 264 specimens representing 62 species or about three-quarters of the species. Species delimitation is particularly difficult in a few widely distributed species with high and allegedly intraspecific DNA barcode divergence of nearly 14%, and with up to 23 BINs in a single species. Deep intraspecific or geographical splits in DNA barcode are frequently not supported by morphology, thus indicating a complex phylogeographic history or other unresolved molecular problems.The following 44 new species (22 of them from Europe) are described:Megacraspedusbengtssonisp. n.(Spain),M.junnilainenisp. n.(Turkey),M.similellussp. n.(Bulgaria, Romania, Turkey),M.golestanicussp. n.(Iran),M.tokarisp. n.(Croatia),M.nelisp. n.(France, Italy),M.faunierensissp. n.(Italy),M.gredosensissp. n.(Spain),M.bidentatussp. n.(Spain),M.fuscussp. n.(Spain),M.trineaesp. n.(Portugal, Spain),M.skouisp. n.(Spain),M.spinophallussp. n.(Spain),M.occidentellussp. n.(Portugal),M.granadensissp. n.(Spain),M.heckfordisp. n.(Spain),M.tenuiuncussp. n.(France, Spain),M.devoratorsp. n.(Bulgaria, Romania),M.brachypterissp. n.(Albania, Greece, Macedonia, Montenegro),M.barcodiellussp. n.(Macedonia),M.sumpichisp. n.(Spain),M.tabellisp. n.(Morocco),M.gallicussp. n.(France, Spain),M.libycussp. n.(Libya, Morocco),M.latiuncussp. n.(Kazahkstan),M.kazakhstanicussp. n.(Kazahkstan),M.knudlarsenisp. n.(Spain),M.tenuignathossp. n.(Morocco),M.glaberipalpussp. n.(Morocco),M.nupponenisp. n.(Russia),M.pototskiisp. n.(Kyrgyzstan),M.feminensissp. n.(Kazakhstan),M.kirgizicussp. n.(Afghanistan, Kazakhstan, Kyrgyzstan),M.ibericussp. n.(Portugal, Spain),M.steinerisp. n.(Morocco),M.gibeauxisp. n.(Algeria, Tunisia),M.multipunctellussp. n.(Turkey),M.teriolensissp. n.(Croatia, Greece, Italy, Slovenia),M.korabicussp. n.(Macedonia),M.skuleisp. n.(Spain),M.longivalvellussp. n.(Morocco),M.peslierisp. n.(France, Spain),M.pacificussp. n.(Afghanistan), andM.armatophallussp. n.(Afghanistan).NevadiaCaradja, 1920,syn. n.(homonym),CauloecistaDumont, 1928,syn. n.,ReichardtiellaFilipjev, 1931,syn. n., andVadeniaCaradja, 1933,syn. n.are treated as junior synonyms ofMegacraspedus.

Three New Species

The taxonomy of the Palaearctic Caryocolum schleichi species group is revised, leading to a largely new species concept. Initially described as four different species (C. schleichi, C. arenariella, C. dianthella, C. improvisella), these taxa were later considered as subspecies. Recently the taxon C. arenariella was re-instated to species level without, however, revision of the remaining three subspecies. Analysis of DNA barcodes of the mtCOI (Cytochrome c Oxidase 1) gene of all four validly described taxa showed an unexpected pattern of genetic diversity. Careful re-examination of morphological traits, particularly male and female genitalia, fully supported this pattern, leading to the re-instatement of C. dianthellasp. rev. and C. improvisellasp. rev. as valid species and the description of three new species, all of them occurring in the Alps: C. messnerisp. nov. (Italy, Slovenia, Bulgaria, Greece), C. lamaisp. nov. (Italy, France) and C. habelerisp. nov. (France, Switzerland, Germany). All species are described in detail and the adults and genitalia of both sexes are illustrated.

Two new species of Leptanilloides are described: L. copalinga Delsinne & Donoso sp. nov., and L. prometea Delsinne & Donoso sp. nov., based on workers collected in the leaf litter and soil of the Andes of southern Ecuador. Both species belong to the L. biconstricta species-group (formally diagnosed here). The metatibial gland, considered a synapomorphy for Dorylinae, is observed in L. prometea sp. nov. but seems absent in L. copalinga sp. nov. We provide a COI DNA barcode for both species and a revised key for the worker caste of all known species in the genus. We also describe a single male identified as a potential new Leptanilloides species on the basis of morphology. Furthermore, its mitochondrial COI gene sequence does not match any previously barcoded species. However, we refrain from giving it a specific name because of our lack of knowledge about the worker caste. So far, half of the 14 Leptanilloides species have been discovered above 1500 m in the mountain forests or páramos of the Ecuadorian Andes, confirming, if needed, the biological significance of these threatened habitats.

Three New Species

The Saturniidae is one of the most emblematic families of moths, comprising nearly 3000 species distributed globally. In this study, DNA barcode analysis and comparative morphology were combined to describe three new species within the genus Automeris, which is the most diverse genus in the family. Automeris llaneros Decaëns, Rougerie & Bonilla, sp. nov., Automeris mineros Decaëns, Rougerie & Bonilla, sp. nov., and Automeris belemensis Decaëns, Rougerie & Bénéluz, sp. nov. are described from the Colombian Orinoco watershed, the Colombian Eastern Cordillera, and the area of endemism of Belém in the Brazilian Amazonia, respectively. They all belong to the Automeris bilinea (Walker, 1855) species subgroup, which comprises a number of species that are sometimes difficult to distinguish from each other using morphology alone. Here, the description of these three new species is based on significant differences from their closest relatives, either in terms of wing patterns, genitalia, DNA barcodes or a combination of these features.

Taxonomic Confusion

Akodon oenos Braun, Mares, and Ojeda, 2000 was described on a large sample of individuals collected from two localities near Mendoza city, Argentina. This sample was obtained in the 1980’s by Julio R. Contreras and María I. Rossi and labeled, but never published, as “Akodon minoprioi new species.” The description provided by Braun and collaborators was limited to craniodental and color pelage traits compared with those of five individuals of the sympatric form A. molinae Contreras, 1968. Akodon oenos was proposed as new and presumptively allied to the A. varius species group of Akodon. In February 2009 we collected an individual of Akodon in Llancanelo Natural Reserve, southern Mendoza, that morphologically fits the original description of A. oenos. Further study of some individuals of the type series of A. oenos reinforces this taxonomic hypothesis for the Llancanelo specimen. However, comparisons with other Akodon species overlooked by Braun and collaborators, reveals striking similarities with the widespread and phenotypically variable species A. spegazzinii Thomas, 1897. The evidence at hand, including morphological, karyological, and genetical traits, allows us to propose a new taxonomic scenario. A. oenos is considered here a junior synonym of A. spegazzinii and therefore belongs to the A. boliviensis species group of Akodon, extending the known geographic distribution for this species at least to southern Mendoza piedmont in the ecotone between the Monte and Patagonia eco-regions. More generally, this situation highlights the necessity when working with complex genera (as many sigmodontines are) to perform extensive comparisons and to use several sets of evidence in order to reduce the probability of generating biologically redundant names and more taxonomic confusion.

Megacraspedus laseni sp. nov. is described from Dolomiti Bellunesi (Veneto Region, Prov. Belluno, Italy). The habitus of the adult and male genitalia are described and illustrated whereas the female sex remains unknown. The new species belongs to the Megacraspedus pentheres species group and is closely related to the southern alpine M. eburnellus Huemer & Karsholt, 2001 from which it differs in morphological characters and in DNA barcode sequence. Megacraspedus carolustertius Gastón & Vives, 2020 is synonymized with M. quadristictus Lhomme, 1946, syn. nov.

A New Species

The assembly of a DNA barcode library for Australian Lepidoptera revealed that Oenochroma vinaria Guenée, 1858, as currently understood, is actually a mix of two different species. By analyzing DNA barcodes from recently collected specimens and the 150 year-old female lectotype of O. vinaria, we propose a reliable assignment of the name vinaria to one of these two species. A lectotype is designated for Monoctenia decora, a confirmed synonym of O. vinaria, and a new species, Oenochroma barcodificata sp. nov., is described. This species is only known from Tasmania and New South Wales; its biology and immature stages are described in detail.

In addition, seven new synonyms were recognized: P. acongruens (Zhang & Shi, 1997), syn. nov.; P. antillaria (Chen & Toda, 1997), syn. nov.; P. kukuanensis Máca, 2003, syn. nov.; P. linae (Máca & Chen, 1993), syn. nov.; P. shillongensis (Singh & Gupta, 1979), syn. nov.; P. takadai (Okada, 1977), syn. nov.; and P. watanabei (Máca & Lin, 1993), syn. nov. A key to all Asian species (except for the eparmata species complex) of this subgenus was provided. All currently available DNA barcode (partial mitochondrial cytochrome c oxidase subunit I (COI) gene) sequences of this subgenus (217 sequences of 54 species) are employed in a molecular analysis using different species delimitation methods. The results indicate that approximately 68.5% (37 of 54 spp.) of Phortica (s. str.) species could be clearly distinguished from closely related morphospecies or cryptic species.
