Aphidinae: Aphidini


Apterae small to medium-sized, grey-brown to reddish brown, on undersurface of leaves of host plants along the main veins, or in dense colonies on young shoots, attended by ants. Alatae have a reddish brown to dark-brown abdomen. Apterae and alatae both 1.3-2.4 mm long. Siphunculi always shorter than cauda; 0.04-0.06x as long as body. Body 1.5x as long as antennae.

The aphid can be easily distinguished from other Toxoptera species by the presence of very small siphunculi and absence of shiny abdominal dorsum in adults.


South and southeast Asia; widespread in Africa south of the Sahara. Found throughout India.
