Higher-level relationships within the Lepidoptera, and particularly species-rich subclade Ditrysia, are generally not well understood, although recent studies have yielded progress. We present most comprehensive molecular analysis of lepidopteran phylogeny to date, focusing on among superfamilies.483 taxa spanning 115 124 families were sampled for 19 protein-coding nuclear genes, from which maximum likelihood tree estimates bootstrap percentages obtained using GARLI. Assessment heuristic...

Abstract The need for robust estimates of times divergence is essential downstream analyses, yet assessing this robustness still rare. We generated a time-calibrated genus-level phylogeny butterflies (Papilionoidea), including 994 taxa, up to 10 gene fragments and an unprecedented set 12 fossils host-plant node calibration points. compared marginal priors posterior distributions assess the relative importance former on latter. This approach revealed strong influence root age but most...

In this catalog, we attempt to assemble all fossil records of Lepidoptera described formally or informally in the worldliterature. A total 667 dealing with at least 4,568 specimens have been compiled. They include descriptions of131 genera and 229 species, as well 72 extant 21 species which some these fossilssupposedly belong show superficial similarity.

Background Yponomeutoidea, one of the early-diverging lineages ditrysian Lepidoptera, comprise about 1,800 species worldwide, including notable pests and insect-plant interaction models. Yponomeutoids were earliest lepidopteran clades to evolve external feeding extensively colonize herbaceous angiosperms. Despite group's economic importance, its value for tracing early evolution, biodiversity phylogeny Yponomeutoidea have been relatively little studied. Methodology/Principal Findings Eight...

The eminent entomologist Aristide Caradja (1861-1955) published between 1925 and 1939, on his own or jointly with Edward Meyrick, a series of taxonomic papers Chinese microlepidoptera including the descriptions 18 new species in Yponomeutidae (Hyponomeutidae authors). Their type specimens are currently deposited two institutions, Natural History Museum London (BMNH: formerly British History), as previously incorporated Meyrick collection, "Grigore Antipa" National Bucharest, Romania (MGAB),...

The genus Naryciodes was originally proposed as a monobasic (type species: posticalis Matsumura) by Matsumura (1931) in Tineidae. About fifty years later, the transferred to Limacodidae Inoue (1982) because larvae possess an autapomorphic character of Limacodidae: lack crochets on prolegs (Epstein et al. 1999).

It is conventionally accepted that the lepidopteran fossil record significantly incomplete when compared to records of other, very diverse, extant insect orders. Such an assumption, however, has been based on cumulative diversity data rather than using alternative statistical approaches from actual specimen counts. We reviewed documented specimens record, currently consisting 4,593 known are comprised 4,262 body fossils and 331 trace fossils. The temporal distribution shows significant bias...

External genital features illustrated. Piercing oviscapts reported Gelechioidea for the first time. The occurrences in Lepidoptera reviewed.

Abstract The T ineoidea are the earliest‐originating extant superfamily of enormous clade D itrysia, whose 152 000+ species make up 98% insect order L epidoptera. Though more diverse than all non‐ditrysian superfamilies put together (3719 vs 2604 species), tineoids not especially species‐rich among ditrysian superfamilies. Their phylogenetic position, however, makes potentially important for understanding causes hyperdiversity, through their effect on inferences about traits ancestral...

Abstract Gracillariidae are one of the most diverse families internally feeding insects, and many species economically important. Study this family has been hampered by lack a robust comprehensive phylogeny. In present paper, we sequenced up to 22 genes in 96 gracillariid species, representing all previously recognized subfamilies genus groups, plus 20 outgroups other superfamilies. Following objective identification removal two rogue taxa, datasets were constructed: dataset 1, which...

Abstract The G elechioidea (&gt;18 000 species), one of the largest superfamilies L epidoptera, are a major element terrestrial ecosystems and include important pests biological model species. Despite much recent progress, our understanding classification, phylogeny evolution remains limited. Building on molecular studies this superfamily recently revised family/subfamily we provide an independent estimate among‐family relationships, with little overlap in gene sample. We analysed up to five...

Background The early history of the Lepidoptera is poorly known, a feature attributable to an inadequate preservational potential and exceptionally low occurrence moth fossils in relevant mid-Mesozoic deposits. In this study, we examine particularly rich assemblage morphologically basal moths that contribute significantly toward understanding lepidopteran biodiversity.

With phylogenetic knowledge of Lepidoptera rapidly increasing, catalysed by increasingly powerful molecular techniques, the demand for fossil calibration points to estimate an evolutionary timeframe order is becoming pressing issue. The family Nepticulidae a species rich, basal branch within phylogeny Lepidoptera, characterized larval leaf-mining habits, and thereby represents potentially important lineage whose history can be established more thoroughly with potential use points. Using our...

Insect-feeding damage on plants provides insight into plant–insect interactions along environmental gradients. However, cataloging such has been limited for fossil flora or extant tropical vegetation. We explored the diversity of insect-feeding Quercus mongolica; one major tree species in East Asian temperate forests. Eighty-six types were cataloged from five sites three mountains Korea. Each type identified our study was compared to previously proposed damage. The possible confirmed origin...

Koreagrypnus jinju nov., are described based on two pairs fossils from the late Early Cretaceous Jinju Formation in City, South Korea. Both represent youngest occurrences an extinct elaterid subfamily, Protagrypninae. is largest known fossil elaterid.
