The endemic Hawaiian genus Swezeyana Caldwell, 1940 is highly distinctive due to the extremely long genal processes. In addition, some of the immatures are ornamented with extraordinary tubercles and tentacles. Two Swezeyana species are redescribed, and seven new species are described, bringing the total number of species in the genus to nine. All species are hosted by a single, endemic host plant, Planchonellasandwicensis (Sapotaceae), which is distributed across all major islands in the archipelago. The majority of Swezeyana species are single island endemics. A sister taxon pair is found sympatrically on the same individual plants on Kauai, and putative sister or at least closely related species are also found sympatrically on Oahu and Hawaii, suggesting these taxa may have diversified in sympatry. However, there is no observed ecological niche partitioning, despite some striking morphological diversity, as all Swezeyana species have free-living immatures that are found on the leaf surface, and therefore no apparent biological shifts are coincident with occupying the same host plant. Two species groups are represented by strikingly different female terminalia structure and endoskeletal development, although ovipositor structure is very similar between the two groups. Mitochondrial DNA barcodes (COI and cytB) are provided for eight of the nine species. A phylogenetic analysis of the mitochondrial barcode regions indicates species relationships within Swezeyana and provides a comparison of genetic divergence with other Hawaiian endemic genera.

Two new endemic species of scarab beetles are described from Costa Rica, Onthophagus humboldtisp. nov. and Uroxys bonplandisp. nov.Onthophagus humboldtisp. nov. is also the tenth brachypterous Onthophagus species to be described worldwide, representing also a case of extreme brachyptery in Onthophagini. Illustrations for both new species, as well as marking differences with closely related species are included. Maps showing the distribution of the new species, as well as the distribution of brachypterous and endemic scarab-beetle species for Costa Rica are presented and discussed. The Cordillera de Talamanca represents an area where Scarabaeinae (four genera) show very high known levels of brachypterism in Mesoamerica. A reconstruction of the montane environment in the Cordillera de Talamanca during the Last Glacial Maximum (~24 ka) is analyzed, in order to try to understand a possible historical biogeography model that might promote high levels of brachypterism in scarab-beetles. The present study supports previous proposals that brachyptery is correlated with stable environments associated with deeply incised valleys. Tropical mountain ranges are also identified as having more endemics than lowland rain forests, contradicting accepted wisdom. Lastly, a mitochondrial DNA analysis supports the existence of the Onthophagus dicranius and the O. clypeatus species-groups as two well-defined and closely related branches.

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.

The subfamily Parornichinae and thus the genus Parornix Spuler, 1910 are reported for the first time in China. Two new species, P. sinensis Liu, sp. n. feeding on Amygdalus davidiana and P. yuliella Liu & Teng, sp. n. on Cerasus japonica, are described herein. Both host plant species belong to Rosaceae. Adult, genitalia of both sexes, and leaf mines are described and illustrated for both species. A Maximum Likelihood tree based on DNA barcodes available for Parornix is also provided for species separation. Reference barcodes for both new species are generated.

Examination of differences in phenetic variation between a number of closely related species of mites of the family Phytoseiidae from four widely different environments in North America, ranging from subarctic to subtropical, was undertaken. Phenetic variation was measured by (1) determining the numbers of taxa recorded in given areas as a measure of the richness of species and genera; (2) determining interspecific morphological diversity using multivariate techniques based on frequency distributions of the taxonomic distances between pairs of species; and (3) by using phenogram analyses to determine the species groups in a given area.The results show a consistent trend in the degree of diversity. The more northerly communities have fewer taxa and these show little phenetic diversity, whereas the more southern communities have more taxa and they show greater phenetic diversity.

The North American fauna of Drymeia Meigen was studied. Four new species are described (Drymeia huckettisp. nov., Drymeia pontisp. nov., Drymeia vockerothisp. nov., Drymeia woodorumsp. nov.), and three new synonymies are proposed: Drymeia amnicola (Huckett, 1966) (= Drymeia rivalis (Huckett, 1966), syn. nov.); Drymeia glacialis (Rondani, 1866) (= Drymeia alpicola (Rondani, 1871), syn. nov.); and Drymeia spinitarsis (Aldrich, 1918) (= Drymeia longiseta Sorokina & Pont, 2015, syn. nov.). An annotated checklist, DNA barcodes (when available), and keys for each sex of the 24 named species of North American Drymeia are provided. The utility of DNA barcodes for the identification of Drymeia species across a wide geographical range was explored using sequences from five countries. A match between morphology and DNA barcodes was found for 71% (22/31) of species studied (including three unnamed taxa). The remaining nine species clustered into two groups of taxa with very little interspecific variation within clusters (groups of two and seven species). Caution is advised against using DNA barcoding as the only determination tool for Drymeia material without prior knowledge of its limitations for certain species groups.

The genus Antispila Hübner, [1825] is newly recorded from mainland China. Antispila sinensissp. n., the first formally named Heliozelidae species in mainland China, is described. The host plant of the new species, Cornus walteri Wangerin (Cornaceae), is widespread through east Asia and is used as a shade tree in city parks in Jinan City, where the moth causes damage to foliage. Morphological and molecular analyses distinguish A. sinensissp. n. from its close relatives. The adult, pupa, larva, host plant, leaf-mines, and the shield of the new species are illustrated, as are male and female genitalia, venation, and larval chaetotaxy. DNA barcodes of the new species are also provided.

Until now, 20 species of leaf-mining micromoths of the genus Phyllocnistis Zeller (Lepidoptera, Gracillariidae) have been known to occur in the Neotropical region. Here we revise the previously known species and describe seven new species: four from French Guiana, P. kawakitai Brito & Lopez-Vaamonde, sp. nov., P. norak Brito & Lopez-Vaamonde, sp. nov., P. ohshimai Brito & Lopez-Vaamonde, sp. nov., P. petronellii Brito & Lopez-Vaamonde, sp. nov.; and, three from Brazil, P. helios Brito & Moreira, sp. nov., P. jupiter Brito & Moreira, sp. nov. and P. xylopiella Brito & Becker, sp. nov. Lectotypes are designated for P. aurilinea Zeller, 1877; P. citrella Stainton, 1856; P. rotans and P. sexangula Meyrick, 1915. Detailed descriptions of the pattern of forewing fasciae are provided for all species. Host plant associations, photographs of adults and illustrations of genitalia, when available, are provided for the described species of Neotropical Phyllocnistis. In addition, DNA barcodes were used for the delimitation of some species.

In this revision of the genus Rhytidoponera on the island of New Caledonia, 18 species are recognized: seven previously described taxa (acanthoponeroides Viehmeyer, atropurpurea Emery, fulgens Emery, numeensis Andre, pulchella Emery, versicolor Brown, and wilsoni Brown) and 11 new species (aquila sp.nov., arborea sp.nov., depilis sp.nov., insularis sp.nov., koumensis sp.nov., litoralis sp.nov., luteipes sp.nov., mimica sp.nov., nitidiventris sp.nov., opaciventris sp.nov., and terrestris sp.nov.). All of these species are endemic (except perhaps terrestris, for which there is a questionable record from Vanuatu), and they segregate into four species-groups: acanthoponeroides group (one species), fulgens group (four species), numeensis group (three species) and pulchella group (ten species). Alate queens have not been found in any species, suggesting that colonies are entirely worker-reproductive. The behaviour and nest architecture of species in the pulchella group indicates specialization as foliage-foragers on understorey and forest edge vegetation, in contrast to the ground-foraging tendencies of the remaining species. Some pulchella-group species are involved in mimicry complexes with other ants and other foliage- frequenting arthropods. Closely related species of New Caledonian Rhytidoponera are usually distributed allopatrically, and conspecific populations exhibit a wide range of morphological differentiation.

A new species of pyrenomycete, Nodulosphaeria edgari, is described from western Canada and western U.S.A. A closely related species, Nodulosphaeria olivacea (Ellis) L. Holm, is redescribed from the lectotype and additional collections from western U.S.A. The two species sometimes occur together on the same host plant material. Nodulosphaeria edgari was previously reported from western U.S.A. under the misapplied names Leptosphaeria erigerontis (Berlese) Berlese and Nodulosphaeria olivacea. Species concepts are stabilized based on type studies of the three taxa. Host plant and geographic records are revised.

AbstractThe pupal cremasters of twelve species of Japanese oak-feeding Phyllonorycter are examined. The cremasters, even those of closely related species, are specifically distinct. Combined with descriptions of European and North American species, the present results indicate that the cremaster can be used as a diagnostic character for the species of Phyllonorycter. A new species, P. persimilis, which was previously confused with P. similis Kumata, and the female of P. nipponicella (Issiki), hitherto unknown, are described. The nipponicella complex including these species is reviewed and the speciation of its members is discussed in relation to diversification of the host plant preference.
