Anastatus orientalis Yang & Choi, 2015 (Hymenoptera: Eulpelmidae) is reported for the first time from Korea. It is a solitary endo-parasitoid in egg of Licorma delicatula (Hemiptera: Fulgoridae), Which causes damages to many ornamental and fruit trees in Korea. This species would be a good biological agent for suppression of the spotted lanternfly in Korea. More than 40 specimens of this species were collected in Cheonhyeon-dong, Hanam-city and Samsung-dong, Seoul city. This Korea species was compare with that from China in morphlogical characteristics and barcodes region of COI.

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.

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.

The genus of Stomaphis (Aphididae: Lachninae) is stem or root feeding aphid on trees and can be easily distinguished in having the very long rostrum which extends beyond the length of body. Most of species are monoecious holocyclic without host alternation and attended by ants. Based on body appearance and COI gene sequence, we report a Stomaphis betulidahuricae Zhang and Qio, 1999 (Aphididae: Lachninae) for the first time in Korea, on Carpinus cordata Bl., C. laxiflora Bl., and Acer palmatum Thunb.
