Comments.

Adialytus salicaphis differs from other congeners in having very elongated first metasomal tergite (petiole) (Fig 5D), and short and dense marginal setae of the fore wing (Fig 3D). It can also be differentiated from Adialytus arvicola by the number of longitudinal placodes on flagellomere 1 (3-5 in Adialytus salicaphis vs. 0-1 in Adialytus arvicola ). The specimens of Adialytus salicaphis associated with Salix spp., especially those reared from Chaitophorus salijaponicus niger on Salix alba , were slightly different from the specimens that reared from Chaitophorus spp. on Populus . The major differences were the lesser number of setae on the clypeus (4-5 vs. 8-10), lesser longitudinal placodes on the first flagellomere (1-2 vs. 3-5) and predominantly adpressed and short setae on the flagellomeres and hind femur compared with the long semi-erect to erect setae among the short setae in specimens from Populus .
