Cinara (Cinara) cedri cedri Mimeur, 1936 is extensively distributed in Europe (France, Italy, Spain, and UK), North Africa (Morocco and Algeria), North America (California and New York), South America (Argentina), Middle East (Cyprus, Iran, Iraq, Israel, Lebanon, Syria, and Turkey), and Asia (China). Recently, this species was also invaded into China. In 2018, C. (Cinara) cedri cedri was firstly discovered on one plant, Cedrus deodara, in Korea. In this study, we provide full redescription in detail.

The aphid genus Stomaphis Walker, 1870 (Hemiptera: Aphididae: Lachninae) is Palaearctic origin group with 30 valid species. It is associated with variable woody host plants, having very long rostrum, which enables them to feed crevices in thick bark of trees. In this study, Stomaphis (stomaphis) pini pini is newly recorded in the Korean Peninsula on Pinus densiflora (Pinaceae). We described morphological features of alate viviparous females, apterous males and oviparous females, respectively. Furthermore, little known forms, sexual morphs of giant oviparous females and dwarfish apterous males are observed.

The subfamily Lachninae Herrich-Schaeffer, 1854 consist of about 400 species belonging to 19 genera world-wide. Lachninae are distributed mostly in the Nearctic, Oriental and Palaearctic Regions. Their host plants are known as grasses, deciduous tree and conifers. Taxonomic study of Lachninae has been dealt with some authors in several countries, whereas it has rarely performed in the Korean Peninsula after Lee et al. (1994). Here, we review the subfamily Lachninae from the Korean Peninsula, focusing on its taxonomic history and diversity.

The oviparous female and male of Stomaphis betulidahuricae Zhang and Qio, 1999 (Aphidoidea: Lachninae) are described and illustrated in detail for the for the first time. Notes on distribution, biology and host plants are presented. Also, the morphology of the male genitalia are illustrated.
