Aphididae: Drepanosiphinae


The aphid is bright brick red, with dull white coloured processi on the whole body. The processi on the head are the shortest and those on the abdomen longest; the processi basally broad, narrowing to a point with faint imbrication and a hair at the apex. Antennae 0.53x as long as body length. Processus terminalis smaller than base and 0.78x as long as base of last antennal segment. Siphunculi broad, ring-like with dark rim. Cauda knobbed, bears 8 long fine hairs.

The aphid colonises the lower surfaces of young and old leaves and continuous sap sucking leads to development of dry patches on the leaves.


Known only from India (Karnataka).
