Abstract


Stomaphis (Stomaphis) matsumotoi Sorin, 1995 is reported on Juglans mandshurica Maxim. (Juglandaceae) for the first time in Korea. Photos of live aphids, illustration of slide specimens, and biometric data of apterous viviparous females are presented.

초록


본 연구에서는 가래나무를 흡즙하는 Stomaphis matsumotoi Sorin, 1995를 국내 최초로 보고한다. 무시충의 생체 사진과 표본을 통한 형태 정보를 수록하였다.



    The genus Stomaphis Walker, 1870 comprises of 37 Palaearctic species, feeding on trunks or roots of various deciduous trees and conifers (Blackman and Eastop 2020;Favret, 2020). This genus is morphologically distinguished from other female aphids by the large body length and rostrum much longer than the body (Depa and Mróz, 2013). To date, four species of Stomaphis have been documented from Korea: Stomaphis asiphon Szelegiewicz, 1975; S. japonica Takahashi, 1960; S. sinisalicis Zhang and Zhong, 1982; S. yanonis Takahashi, 1918. Here, we report Stomaphis matsumotoi on Juglans mandshurica Maxim. (Juglandaceae) for the first time in Korea.

    Materials and Methods

    Colonies of Stomaphis matsumotoi individuals were found on the trunks of Juglans mandshurica Maxim. (Juglandaceae) in 2019. The fresh aphid samples were preserved in 95% alcohol and slide glass specimens were mounted on Canada balsam, following Blackman and Eastop’s (2000) methods. Measurements and digital images were taken using Leica DMC 5400 (Leica Z16 APO) and Leica DM 4000B (Active Measure version 3.0.3; Mitani Co. Ltd., Japan). The samples examined in this study are deposited in the College for Agri- culture and Life Sciences, Seoul National University (Korea). The synonym information of the plant follows The Plant List (2013). Abbreviations used for descriptions are as follows: apt., apterous viviparous female; Ant, antennae; Ant I, Ant II, Ant III, Ant IV, Ant V, Ant VIb, and PT, antennal segments I, II, III, IV, V, base of VI, and processus terminalis of antennomere VI respectively; BL, body length; HW, greatest head width across compound eyes; GP, genital plate; HT Ⅰ, first segment of hind tarsus; HT II, second segment of hind tarsus; MT II, second segment of middle tarsus; SIPH, siphunculi; URS, ultimate rostral segment (segment IV+V); AbdT I–VIII, Abdominal tergites I–VIII respectively.
