Colour (macerated specimens). Body extremely blackish, slightly bright in the spinal part of abdomen. Antennae pale, except Ant. I, distal part of Ant. IV, Ant. V., Ant. VIb and PT. Legs pale, except mid- and hind femora, basal part of hind tibia and 2 HT. Cauda and anal plate distinctly pale. SIPH dark as body colour. Morphology. Body elongated oval-shaped; about 2.20 mm long. Head: smooth, seta very long and spine. Antenna slender; whole antennae almost 0.57 times as long as body length; PT 2.73 times as long as Ant. VIb. URS short and slightly blunt, with eight or more setae. Thorax: pronotum smooth. Hind femur and tibia about 0.55 mm and 0.69 mm long, respectively; Abdomen: abdominal tergites fused from I to VI, with blunt or furcate seta; dorsum with pore-like microstructure in a row of each segment. SIPH short and finely reticulate. Cauda distinctly knobbed with six setae. Host plants P. maximowiczii, P. sieboldii, P. simonii, P. tremula (Blackman and Eastop 2024). Diagnosis C. tremulae closely resembles C. salijaponicus morphologically. However, it can be distinguished by body length and marginal tergites: in C. tremulae, body length is longer than 1.8 mm and has no sclerotised marginal tergites, whereas in C. salijaponicus, body length is shorter than 1.8 mm and sclerotised marginal tergites are developed. Distribution Korea (new record), Great Britain, Netherlands, Germany, Denmark, Spain, Norway, Finland, Poland, Hungary, Turkey, Russia, Caucasus, Kazakhstan, Siberia, China, Mongolia, Japan (Blackman and Eastop 2024).
