A new species and new record of the leaf-mining genus Dactylotula Cockerell (Lepidoptera: Gelechiidae) from China.

Until recently, only two species of Dactylotula Cockerell, 1888 have been known. Dactylotula kinkerella (Snellen, 1876), feeding on Calamagrostis arenaria (L.) Roth (Poaceae), is distributed in Europe and the Asian part of Russia, while D. altithermella (Walsingham, 1903) was only recorded in Europe with host plant unknown. Here, we report Dactylotula for the first time in China represented by a new leaf-mining species described herein as D. phragmitella, sp. n., feeding on Phragmites australis (Cav.) Steud. (Poaceae). Most of the specimens were collected in the Yellow River Delta. Photos of the adult, wing venation, male and female genitalia, host plant, leaf mines and parasitoid wasps of the new species are provided. Additionally, DNA barcodes of the new species are provided and discussed along sequences of the other two congeneric species.

The leaf-mining genus Lyonetia Hbner from China, with descriptions of two new species (Lepidoptera: Yponomeutoidea: Lyonetiidae).

So far, only five species of the genus Lyonetia Hbner, 1825 have been recorded in China. In this paper, we describe two new species: L. (Lyonetiola) blasta T. Liu, sp. n., and L. (Lyonetiola) duplistriata T. Liu, sp. n., and report a newly recorded species, L. (Lyonetia) ledi Wocke, 1859 from China. Autumnal forms, manifesting darker forewings, of L. (Lyonetia) clerkella (Linnaeus, 1758) were collected from Xizang at an altitude of 3650 m in summer. The distribution and host plants of L. (Lyonetia) clerkella (Linnaeus, 1758) and L. (Lyonetia) prunifoliella (Hbner, 1796) in China are summarized. Photos of adults, male and female genitalia are provided. Host plants, leaf mines and DNA barcodes are also provided when available.

First Report of the Immature Stages of the Leaf-Mining Genus Subclemensia Kozlov, 1987 (Lepidoptera: Incurvariidae), with a Re-Illustration of the Type Species and a Generic Concept Discussion Based on Immature Characters.

The immature stages of primitive Lepidoptera can provide quite different but often useful morphological evidence and synapomorphies from those of adults. Incurvariidae is one of the most primitive lineages of extant Lepidoptera, which is species-poor but highly diverse, but half of the genera lack any information on immature stages. New knowledge on the immature stages of the family is expected to provide useful morphological evidence and synapomorphies to stabilize the generic nomenclature. Subclemensia Kozlov, 1987 is one of the monotypic genera in Incurvariidae. In this study, the immature stages of the type species of Subclemensia are reported for the first time. The leaf mine, host plant and its biological characteristics are also provided. DNA barcodes were generated to aid the species delimitation. The adult male and female genitalia are re-illustrated by color photography to supplement the original line drawings. The generic concepts of Subclemensia and other related genera are discussed based on immature characters.

New record of Epermenia (Calotripis) sinjovi Gaedike (Lepidoptera: Epermeniidae) in China: DNA barcode, adult, immature stages, host plant and biology.

Epermenia (Calotripis) sinjovi Gaedike, 1993, feeding on Angelica pubescens Maxim. and A. ursina Maxim., was previously recorded in Russia (Far East, Southern Siberia and Transbaikalia), Kunashir Island and Japan. This species is for the first time reported in China by rearing from a new host plant A. polymorpha Maxim. The larva and pupa are illustrated and described for the first time. Available biological information associated with the new host plant is also reported. Reference DNA barcodes are provided for E. (C.) sinjovi, which confirms that forewing distinct colors and morphological differences found in venation and genitalia among individuals are intraspecific variations. The adult morphological variations within population are analyzed and discussed.

Taxonomic study of the genus Blastobasis Zeller, 1855 (Lepidoptera: lastobasidae) from China, with descriptions of six new species.

The ten species of the genus Blastobasis Zeller, 1855 recorded from Mainland China are reviewed, of which six are described as new: B. spinisetosa, sp. nov., B. divulgata, sp. nov., B. adamskii, sp. nov., B. aciformis, sp. nov., B. edentula, sp. nov., and B. hamata, sp. nov. Blastobasis parki Sinev, 1986 and B. inouei Moriuti, 1987 are recorded for the first time in China. Images of adults and genitalia are provided. A key to the species of Mainland China and a map showing their distributions are included.

Taxonomic study of the genus Hypatopa Walsingham, 1907 (Lepidoptera: Blastobasidae) in China, with descriptions of five new species.

The eight species of the genus Hypatopa Walsingham, 1907 recorded from China are reviewed, five of which are described as new: H. biprojecta, sp. nov.; H. weibaoshana, sp. nov.; H. apicirecta, sp. nov.; H. huayingshana, sp. nov.; and H. orthocera, sp. nov. Hypatopa moriutiella Sinev, 1986 and H. binotella (Thunberg, 1794) are recorded for the first time from China. Photographs of adults and genitalia are provided. A key to the Chinese species and a map showing the distribution of these species are included.

Taxonomic study of the genus Halolaguna Gozmány (Lepidoptera, Lecithoceridae) from China, with descriptions of two new species.

The genus Halolaguna Gozmány, 1978 is studied in China. Two new species, Halolagunaflabellata sp. n. from Guangxi and Halolagunadiscoidea sp. n. from Chongqing, Guangxi and Sichuan are described. The female of Halolagunaguizhouensis Wu, 2012 is reported for the first time. Photographs of adults and genitalia are provided. A checklist of all known Halolaguna species is included, along with a key to the Chinese species.
