The Lepidoptera (Butterflies and Moths) first appear in the fossil record in the Early Jurassic of southern England, though they may be a little older; their closest relatives, the Caddisflies (Trichoptera) being known from the Late Triassic. Fossil Lepidopterans are not numerous in Mesozoic deposits, suggesting that the group did not become a major component of Insect faunas until the Cenozoic.
The first new species described is named Seresilepidopteron dualis, where 'Seresilepidopteron' means 'Lepidopteran from northwest China' and 'dualis' means 'twice'. This is a 4.3 mm Moth described from two specimens, thought to be members of the same species but different sexes.

The second new species is named Akainalepidopteron elachipteron, where 'Akainalepidopteron' means 'spiny Lepidopteran' and 'elachipteron' means 'short wing'. The species is described from two female specimens and a partial specimen of uncertain sex. The Moths were about 7.2 mm in length, with forewings shorter than the body.

The third new species described is named Dynamilepidopteron aspinosus, where 'Dynamilepidopteron' means 'Powerful Lepidopteran' and 'aspinosus' means 'lacking spines'. The species is described from a single male specimen, 7 mm in length.

The seventh new species described is named Grammikolepidopteron extensus, where 'Grammikolepidopteron' means 'linear Lepidopterean' and 'extensus' means 'extended'. The species is described from a single female specimen preserved as part and counterpart, 3.8 mm in length, but missing the tip of the abdomen.

The eighth new species described is placed in the genus
Mesokristensenia, and given the specific name
trichophora, meaning hair-carrier, a reference to a cluster of hairs on the base of the antennae.
Mesokristensenia trichophora is described from a single female specimen, 5.1 mm in length.

The ninth new species described is named
Kladolepidopteron oviformis, where '
Kladolepidopteron' means 'branched Lepidopteran' (a reference to the wing-venation) and '
oviformis' means 'egg-shaped' in reference to a pair of oval structures on the first segment of the thorax. The species is described from a single female specimen, 6.3 mm in length.

The tenth new species described is also placed in the genus
Kladolepidoteron, and is given the specific name
subaequalis, meaning 'less than equal', a reference to the wing venation.
Kladolepidopteron subaequalis is described from a 5 mm specimen of indeterminate sex and an isolated forewing.

The eleventh new species described is again placed in the genus
Kladolepidoteron, and is given the specific name
parva, meaning small.
Kladolepidopteron parva is described from a single male specimen, 4.1 mm in length, preserved as part and counterpart.

The twelfth new species described is given the name
Ascololepidopterix multinerve, where '
Ascololepidopterix' means 'Lepidopteran without spurs' and '
multinerve' means 'many-sinewed', a reference to the wing venation. The species is described from a single 8.1 mm specimen of indeterminate sex.

latiala' means 'broad winged'. The species is described from a single 7.7 mm female specimen.

The final new species is named
Trionolepidopteron admarginis, where '
Trionolepidopteron' means 'Three Lepidopteran', a reference to the wing venation, and '
admarginis' means 'towards the border', another reference to the wing venation. The species is described from a single 3.8 mm partial specimen of indeterminate sex.
