The data presented in this article are related to the research article “Effect of elevation on the insect herbivory of Mongolian oaks in the high mountains of southern South Korea” (Sohn et al., 2019). We collected oak leaves occurring in two mountains: Jirisan Mountain on the mainland of Korea (12 September 2015) and Hallasan Mountain on Jejudo Is...

The need for robust estimates of times of divergence is essential for downstream analyses, yet assessing this robustness is still rare. We generated a time-calibrated genus-level phylogeny of butterflies (Papilionoidea), including 994 taxa, up to 10 gene fragments and an unprecedented set of 12 fossils and 10 host-plant node calibration points. We...

Elevation is strongly associated with the diversity and ecology of plants and animals. We explored how elevation affects herbivores on one of the major cool-temperate trees, Quercus mongolica, in southern South Korea. The feeding activities of insect herbivores were measured through insect-feeding damage on leaves. Of 78 types of insect-feeding dam...

Gracillariidae are one of the most diverse families of internally feeding insects, and many species are economically important. Study of this family has been hampered by lack of a robust and comprehensive phylogeny. In the present paper, we sequenced up to 22 genes in 96 gracillariid species, representing all previously rec- ognized subfamilies and...

We revise the taxonomic status of Eidophasia zukowskyi Amsel, 1938, and we provide the first descriptions of the genitalia of both sexes. A diagnostic summary is given with illustrations for a similar congener, Eidophasia syenitella (Herrich-Schäffer, [1854]).

The Holarctic genus Eidophasia Stephens, 1842 belongs to Plutellidae (Kyrki 1984, 1990; Dugdale et al. 1999). The genus currently includes 12 species (Sohn & Baraniak in press) which are heterogeneous in morphologies. In fact, there have been no convincing synapomorphies proposed for Eidophasia. Eidophasia syenitella (Herrich-Schäffer, [1854]) is o...

The Gelechioidea (>18 000 species), one of the largest superfamilies of Lepidoptera, are a major element of terrestrial ecosystems and include important pests and biological model species.

Morphological features of two new species, including the median lobe of the gnathos and the elongate saccular process with an apical spine, help to further define Incawockia.

Mataeomera Butler, 1886, currently referred to the tribe Eublemmini in Boletobiinae (Holloway 2011), was proposed by Butler (1886) to accommodate an Australian species, Mataeomera dubia Butler. This genus was once regarded as a junior synonym of Autoba Walker by Poole (1989) but resurrected by Edwards (1996). Another related genus, Catoblemma Hamps...

The gracillariid genus Triberta gen. nov. (Lepidoptera: Gracillariidae: Lithocolletinae Stainton, 1854) is described to accommodate two species formerly assigned to the genus Phyllonorycter Hübner, 1822: Triberta helianthemella (Herrich-Schäffer, 1861) comb. nov. and T. cistifoliella (Groschke, 1944) comb. nov. Triberta cistifoliella bona sp. is re...

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