Review of Cotachena Moore, 1885 (Lepidoptera: Crambidae,Spilomelinae) from Korea based on morphology and DNA barcodes

The Korean species of Cotachena were reviewed, based on morphological characters and DNA barcodes. Our study recognized three species of Cotachena from Korea: C. alysoni Whalley, C. brunnealis Yamanaka and C. taiwanalis Yamanaka. The latter two were new to Korea. Dubious occurrence of C. pubescens (Warren) in Korea was discussed. The 23 individuals of COI barcodes were analyzed and assigned to the eleven species of Cotachena. The DNA barcodes of C. taiwanalis and C. brunnealis were provided for the first time and their taxonomic status was discussed. Host plants of C. taiwanalis were first reported. The Korean species of Cotachena were compared to the conspecific populations from neighboring countries. Photographs of habitus and genital features were provided for the Korean Cotachena, if available, to facilitate identification.

Taxonomic review of the genus Orius (Heteroptera: Anthocoridae) in the Korean Peninsula

A total of five species the genus Orius are revised from the Korean Peninsula, containing four native species, O. minutus (Linnaeus 1758), O. sauteri (Poppius 1909), O. nagaii Yasunaga 1993 and O. strigicollis (Poppius 1914), and an introduced species for biological control, O. laevigatus Fieber 1860. Orius laticollis Reuter 1884, formally recorded in the Korean Peninsula, is deleted from the Korean fauna registry. The preparation of the macerated slide specimen was applied to this group for the first time, which is confirmed to be effective to identify the Orius species, especially the female specimens whose genital structures have been hardly observed in the traditional dissection method. Observing macerated specimens, new taxonomical characters are documented.     

Current state of knowledge of the Korean Cynipini: subspecies description,new combinations and checklist (Hymenoptera,Cynipidae)

Prior to this study, only 8 species of oak gall-forming wasps were known from Korea. After material examination and an exhaustive bibliographic revision, a total of 17 oak gall wasps species have been reported. The following species correspond to new records: Andricus hakonensis (Ahmead); A. pseudocurvator Tang & Melika; A. songshui Tang & Melika; Cerroneuroterus folimargo (Monzen); C. monzeni (Dettmer); C. vonkuenburgi (Dettmer); Neuroterus hakonensis Ashmead, Trichagalma acutissimae (Monzen), T. formosana Melika & Tang.

Additionally a new subspecies of Trichagalma formosana is described to include the material from Korea and Mainland China, closely related but morphologically different to the Taiwan populations. For each species live cycle, morphology of galls, hosts, phenology, and distribution are commented. In some of them taxonomic or morphological comments are mentioned and a key of agamic Trichagalma with dark smoky pigmented spots in the forewing is added. All galls are illustrated.
