Remarks. Dr. M. von Tschirnhaus (1992) established synonymy of Phytobia betulae (Kangas, 1935) with P. c a m b i i (Hendel, 1931). Sasakawa (1994) recorded P. betulae from Japan and in fact he re-surrected this name from synonymy. I reject this proposal because Tschirnhaus’s opinion is based on rearing experiments (Tschirnhaus, personal communication).
