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 genus of Cinara (Aphididae: Lachninae) live on the roots, trunk, branches, twigs, shoots or foliage of Coniferae and can be easily distinguished in having the very big body, apterae up to 5-6 ㎜ in length and short antennae which are shorter than half the body length. Most of species are monoecious without host alternation and attended by ants. Based on body appearance and COI gene sequence, we report Cinara cuneomaculata (Del Guercio) on Larix kaempferi, C. largirostris Zhang G. & W. Zhang on Pinus thunbergii and P. dnesiflora, C. smaragdina (Pashtshenko) on Abies holophylla and C. piceae on Juniperus rigida, for the first time in Korea.

Three new species of aphid parasitoids and their host-plant associations are described: Pauesia koraiensis Stary(Cinara cembrae Inouye and C. sp. on Pinus koreaiensis), Pauesia holmani Stary(Cinara sp. and C. watanabei Inouye on Pinus koraiensis, and C. laricis Hartig on larix olgensis) and Pauesia gwangleungensis Stary(Cinara shinjii Inouye on Pinus parviflora).
