    The genus AcyrthosiphonMordvilko, 1914 is classified within the subfamily Aphidinae, which comprises 94 species distributed worldwide (Favret, 2024). The majority of species in this genus is distributed across the Palaearctic region (Heie, 1994). The genus is comprised of three subgenera, the nominotypical Acyrthosiphon (91 species), LiporrhinusBörner, 1939 (1 species) and XanthomyzusNarzikulov, 1969 (2 species) (Favret, 2024;Eastop and Hille Ris Lambers, 1976). The species in this genus are known to feed on a variety of dicotyledonous plants, particularly Fabaceae, Rosaceae, and Euphorbiaceae, without exhibiting host alternation (Blackman and Eastop, 2024).

    Presently, five species have been reported on South Korea (Paik, 1972;Lee et al., 2002); Acyrthosiphon (Acyrthosiphon) pisum (Harris, 1776) was recorded by Okamoto and Takahashi (1927), A. (Liporrhinus) chelidonii (Kaltenbach, 1843) was recorded by Shinji (1941), A. (Acyrthosiphon) malvae (Mosley, 1841) was recorded by Paik (1965), A. (Acyrthosiphon) gossypiiMordvilko, 1914 and A. (Acyrthosiphon) kondoiShinji, 1938 were recorded by Paik (1972). In 2019, Acyrthosiphon (Acyrthosiphon) lactucae (Passerini, 1860) was identified as a new collection on Lactuca sativa L. (Asteraceae) in South Korea. Consequently, a total of six species are distributed in South Korea. In this study, we report the apterous viviparous female of Acyrthosiphon (Acyrthosiphon) lactucae for the first time in South Korea and provide species descriptions, measurements, host plants, and distributions.

    Materials and Methods

    In 2019, colonies of A. (Acyrthosiphon) lactucae were collected on Lactuca sativa in 2019. The aphid samples were preserved in 95% alcohol and slide glass specimens were mounted on Canada balsam, following the method of Blackman and Eastop (2000) methods. The images and measurements were obtained using a LEICA (DM3000 LED) and a LEICA (CTR6 LED). All specimens were deposited at the Institute of Agriculture & Life Science, Gyeongsang National University. The following abbreviations are used in the description of morphological features: BL, body length from the head to the end of the cauda; Ant., antennae; Ant.I - VI and Ant.VIb, antennal segments I - VI, and basal part of antennal segment VI, respectively; PT, processus terminalis; BDAnt.III, basal diameter of antennal segment III; 2HT, second segment of hind tarsus; HFM, hind femur; HTB, hind tibia; SIPH, siphunculus; and URS, ultimate rostral segment.
