Description
Apterous viviparous female (Fig. 3, Table 3). Colour (macerated specimens). Body blackish and oval-shaped, intersegmentally pale on unfused tergites. Antenna and leg slightly grey; hind tibia, Ant. VIb and PT darker than body. Abdominal tergite with a pale ring around base of SIPH. Morphology. Body elongated oval-shaped; about 1.52 mm long; marginal setae around body distinctly long and fine. Head: flat with long pointed setae on frons; mandibular lamina with eight setae. Antenna slender; whole antennae almost 0.55 times as long as body length; PT 2.55 times as long as Ant. VIb.; Ant. III with seven long setae; Ant. V with relatively stunt setae. URS with eight setae. Thorax: hind femur and tibia about 0.31 mm and 0.49 mm long, respectively; length of leg a little shorter than other species in comparison with length of body. Abdomen: abdominal tergites from II to VII fused; more sclerotised on marginal tergites of each segment. SIPH short and reticulate. Cauda knobbed with 6 setae.
Host plants
S. babylonica, S. caprea, S. integra, S. koriyanagi, Salix spp. (Blackman and Eastop 2024).
Diagnosis
C. salijaponicus closely resembles C. hokkaidensis morphologically. However, it can be distinguished by the state of abdominal tergite I: in C. salijaponicus, it is free, whereas in C. hokkaidensis, it is completely fused with the preceding segment.
Distribution
Korea (new record), China, Siberia, Mongolia, Japan (Blackman and Eastop 2024).
