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.

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.

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.

Taxonomic Framework

An integrative taxonomic approach that utilizes the DNA barcode region of cytochrome c oxidase subunit 1 in conjunction with traditional morphological approaches identifies five distinct species previously recognized as Lasioglossum (Dialictus) tegulare (Robertson). Differences in DNA sequences and congruent, albeit minor, morphological variation support separation of L. tegulare into five species. Unique nucleotide substitution patterns for each species allows for character-based diagnostics using DNA barcodes. The names L. ellisiae (Sandhouse) and L. lepidii (Graenicher) are removed from synonymy. Two new species, L. puteulanum Gibbs sp. n. and L. carlinvillense Gibbs sp. n., are described. A key is provided, which permits the identification of both males and females. The utility of the DNA barcode region as part of an integrative taxonomic framework is discussed.

A New Species

Both sexes of a new species, Stylicletodes wellsi sp. nov. (Harpacticoida: Cletodidae), are described from material collected from sediments in the East China Sea. The new species belongs to a species group whose members are characterized by an anal operculum that has a backwardly directed, median linguiform process and fifth legs that display naked or sparsely pinnate armature elements in both sexes. Within this group, S. wellsi sp. nov. is morphologically closest to S. reductus Wells, 1965 but differs primarily from its European congener in the armature pattern of P4 (both rami) and the female P5. Distribution records of all species are summarized and an updated identification key to the seven valid species in the genus is presented. Taxonomic issues related to the type species S. longicaudatus (Brady, 1880) are briefly discussed.

Morphological And Molecular Data

The subgenus Dudaica Strand of the genus Drosophila Fallén has been known to comprise only two species: Drosophila (Dudaica) senilis Duda, 1926 (recorded from Indonesia, Philippines, Vietnam, Bhutan, and India) and D.malayana (Takada, 1976) (recorded from Malaysia). In the present study, this subgenus is revised, with D.malayana redescribed and six new species discovered and described from China, Malaysia, and Indonesia: gracilipalpis Katoh & Gao, sp. n., puberula Katoh & Gao, sp. n., albipalpis Katoh, Toda & Gao, sp. n., qiongzhouensis Katoh & Gao, sp. n., orthophallata Katoh, Toda & Gao, sp. n., and dissimilis Katoh & Gao, sp. n. Both morphological and molecular data (DNA barcodes) are used to distinguish the above species. A key to species of this subgenus is provided.

The genus Myopsalta Moulds is distributed throughout much of Australia. Previous studies have associated several undescribed species with the Myopsalta crucifera (Ashton) species complex. The present study informally divides the cicadas in the genus Myopsalta into two species groups. It provides a revision of the M. crucifera species group, which includes redescriptions of M. crucifera s. str. and M. mackinlayi (Distant). The identity of the latter species is further refined and attributed to material formerly presented under the name Myopsalta atrata (Goding & Froggatt). In addition to the redescriptions, 14 new species belonging to the M. crucifera species group are described, including M. albiventris n. sp., M. bassiana n. sp., M. chrysopedia n. sp., M. gordoni n. sp., M. leona n. sp., M. longicauda n. sp., M. majurae n. sp., M. melanobasis n. sp., M. parvula n. sp., M. platyptera n. sp., M. riverina n. sp., M. septa n. sp., M. umbra n. sp. and M. xerograsidia n. sp. A key to species in the genus Myopsalta is provided. Standard morphological descriptions and descriptions of calling songs unique to each species are included along with a discussion on different song types in the M. crucifera species group.

A New Species

A new species, Baetis pentaphyllus sp. nov., is described on the basis of larvae from the Far East of Russia (type locality Bolshoi Garmakan River). Larvae of Baetis pentaphyllus sp. nov. may be distinguished from other Baetis species by the presence of only five pairs of tergalii on segments III–VII. The mitochondrial COI sequence obtained from the described species was compared with the data present in GeneBank and BOLD. The DNA barcodes allowed discrimination of B. pentaphyllus sp. nov. from other species of Baetis with available sequence data. The average interspecific K2P distances were 10–15%, which are values well above those associated with intraspecific variation. COI sequences as well as 36 morphological larval characters were analysed using Bayesian inference to relate the described species to the recognized species-groups of the Baetis genus. B. pentaphyllus sp. nov formed a sister clade to B. vardarensis + B. lutheri which belong to the Baetis lutheri species-group.
