    The genus GreenideaSchouteden, 1905 includes 66 species in the world (Favret, 2025). The majority of species in this genus are mainly distributed in the South-East Asian region. Some of the species are important agricultural and horticultural pests; Greenidea (Trichosiphum) psidii van der Goot, 1917, Greenidea (Greenidea) ficicola Takahashi, 1921. These have been identified as invasive on a global scale (Liu et al., 2013). This genus consists of three subgenera, the GreenideaSchouteden, 1905 (28 species), ParagreenideaRaychaudhuri, 1956 (4 species) and TrichosiphumPergande, 1906 (34 species) (Favret, 2025;Eastop and Hille Ris Lambers, 1976). Host plants of the species belong to this genus are chiefly Fagaceae, besides Moraceae, Betulaceae, Juglandaceae, Myrtaceae, Rosaceae and Rubiaceae. Information on the life cycle is scarce, typically anholocyclic (Blackman and Eastop, 2025).

    Currently, two species have been reported on South Korea (Paik, 1965;1972); Greenidea (Trichosiphum) kuwanai (Pergande, 1906) was recorded by Okamoto and Takahashi (1927), Greenidea (Trichosiphum) nipponica Suenaga, 1934 was recorded by Paik (1972). In 2023, Greenidea (Trichosiphum) nigra (Maki, 1917) was newly collected on Quercus glauca (Fagaceae) in South Korea. In this study, we report apterous viviparous female of Greenidea (Trichosiphum) nigra for the first time in South Korea and provide species descriptions, measurement, distributions, host plants.

    Materials and Methods

    Colonies of G. (Trichosiphum) nigra had been collected on Quercus glauca in 2023. 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. Images and measurements were taken by LEICA (DM3000 LED) and LEICA (CTR6 LED). All specimens were deposited Institute of Agriculture & Life Science, Gyeongsang National University. The following abbreviations are used in morphological features: BL, body length from the head to the end of 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; SIPH BW, basal width of siphunculi; SIPH MW, maximum width of siphunculi; SIPH DW, distal width of siphunculi; Cauda BW, basal width of cauda; and URS, ultimate rostral segment.
