The Aphid of tea, coffee and cacao (Toxoptera coffeae, Nietner)

Extract

Nietner in 1880 (“ The Coffee Tree and its Enemies ”) described an Aphis from coffee found in Ceylon and Java as Aphis coffeae. The description is as follows:—“ Both sexes naked, shiny pitch-black with whitish rostrum and legs and greenish abdomen. The rostrum reaches beyond the base of the second pair of legs. The antennae are 7-jointed, the first, second and sixth being short, the rest long, the two basal joints are black, the rest are whitish, black towards apex. Legs with femora and tarsi nearly black, tibiae nearly white, hind legs with base of tibiae slightly curved. Male four-winged, with black stigma in the upper ones. Female apterous. Abdomen in both sexes 2-corniculate and with an anal tube. Size moderate. Young individuals light coloured.” Apparently the male and female described refer to the alate viviparous and apterous viviparous female.
