Uroleucon acutirostre Banziger 1980 = Uroleucon budhium (Banerjee, Ghosh and Raychaudhuri 1969)

Paratypes of U. acutirostre, described from N Thailand, could not be distinguished from paratypes and other Indian specimens (leg. N.D. Rishi) of U. tenuirostre ( = budhium ?) in the BMNH collection, so if the synonymy of tenuirostre with budhium is correct, acutirostre should also be regarded as a synonym. However, the colour in life of acutirostre is recorded as dark blackish red, whereas budhium is described as pale brown with a dark brown head, raising some doubt about the original synonymy. The original description of tenuirostre did not record the colour in life.
