    The genus PleotrichophorusBörner, 1930 comprise 62 species in the world (Blackman and Eastop, 2023). Most of species are distributed in America and Europe, and three species, Pleotrichophorus chrysanthemi (Theobald, 1926), Pleotrichophorus glandulosus (Kaltenbach, 1846), and Pleotrichophorus narzikulovi (Narzikulov and Umarov, 1969), have been recorded in Asia (Blackman and Eastop, 2023). Most of species in this genus are pale green to yellow bearing numerous short capitate hairs (Corpuz-Raros and Cook, 1974) and are holocyclic on Compositae (Hille, 1953).

    Until now, two species have been recorded in South Korea: P. chrysanthemi was recorded by Theobald (1926) and P. glandulosus was recorded by Paik (1965). From 2019 to 2020, Pleotrichophorus pseudoglandulosus (Palmer, 1952) has been newly collected on Artemisia princeps Pamp. (Asteraceae) in South Korea. So, in this study, we report apterous viviparous females of P. pseudoglandulosus for the first time in South Korea.

    Materials and Methods

    Colonies of P. pseudoglandulosus had been collected on A. princeps from 2019 to 2020. 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; We - Width across eyes; Ant.I-VI - antennal segments, respectively; Ant.VIb - antennal segment base of VI; PT - processus terminalis; URS - Ultimate rostrum segment; 1HT - first tarsal segment of hind leg; 2HT - second tarsal segment of hind leg; HTB - hind tibia; AP - Anal plate; SIPH - Sipuncula.

    Description. Apterous viviparous female. Morphology. Head and thorax light green and yellow (Fig. 2); Body elongated oval, 2.269-2.614 mm long (Fig. 1A); Head weakly sclerotized, moderately produced laterofrontal tubercle small of each antenna near the base, Head with funnel-shaped 26-36 setae (Fig. 1E); We 0.461-0.524 mm long (Fig. 1B); Ant. brown, 6-segmented, Whole Ant., 2.922-3.241 mm long; Ant.III longer than Ant.IV; Ant.I, Ant.II with 6 setae, Ant.III with 19 setae, Ant.IV with 13 setae, Ant.V with 8 setae, Ant.VIb with 3-5 setae, PT with 3-6 setae; Ant.III bearing 1-3 secondary rhinarium; Ant.V bearing one primary rhinaria; Ant.VIb bearing one primary rhinaria with well developed PT (Fig. 1I); Dorsal abdomen integument, densely cover of funnel- to coneshaped setae; Rostrum reaching the middle Furmorotrochanter, URS cylindrical needle-shaped, both edges are straight or curved inward, with 10 accessory setae, 0.107-0.123 mm long (Fig. 1F); Legs with 3,3,3 hairs on 1st tarsal joints; HTB 1.070-1.435 mm long (Fig. 1C), 2HT 0.114-0.147 mm long, 0.98-1.29 times as long as URS (Fig. 1H); Siphuncula cylindrical- shaped, 0.556-0.687 mm long, 2.33-2.89 times as long as Cauda (Fig. 1B); Anal Plate sclerotized with a total of 10-11 setae; Cauda 0.233-0.275 mm long, weakly sclerotized with 5 setae (Fig. 1G).

    Materials examined. 10 apterous viviparous females, Daejeon-si, South Korea, 09.v.2019, on Artemisia princeps, D.-K. Park, GNU; 2 apterous viviparous females, Imsil-gun, Jeollabuk-do, South Korea, 11.iv.2020, on Artemisia princeps, D.-K. Park, GNU.

    Host plants.Artemisia douglasiana Besser, Artemisia frigida Willd, Artemisia ludoviciana Nutt., Artemisia vulgaris L., Artemisia ludoviciana Nutt. spp mexicana, Artemisia tridentata Nutt. (Palmer), Artemisia princeps Pamp. (new record) (Asteraceae).

    Distributions. Korea (new record), USA, Canada.

    Remark. According to Corpuz-Raros and Cook (1974), P. pseudoglandulosus is similar to P. glandulosus. However, P. pseudoglandulosus has much shorter and funnel-shaped posterior body setae than those of P. glandulosus. In addition, SIPH/Cauda ratio (2.98 times) of P. pseudoglandulosus is higher than that (2.01 times) of P. glandulosus.
