Placoaphis siphunculata Richards 1961


Placoaphis siphunculata Richards 1961  = Ericaphis wakibae (Hottes 1934) 

This synonymy was proposed by C.F. Smith ( Remaudière & Remaudière, 1997). P. siphunculata  was described from alate specimens on Rosa  in British Columbia. Comparisons with alatae from several samples of E. wakibae  from British Columbia collected by C.­k. Chan, and with the introduced UK population, support the synonymy.
