Description

Apterous viviparous female (Fig. 3 View Figure 3 , Table 3 View 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).
