Abstract
The genus
Greenidea
comprises about 45 East
Asian species of pear-shaped aphids with 6-segmented
antennae, long hairy and pale reticulated
siphunculi, rounded cauda with a median processus
and 7.7.7 setae on first tarsal segments (Sugimoto
2008). The alatae viviparous females are
more long-bodied and have longer siphunculi
than the apterous ones. About half the species are
included in subgenus
Trichosiphum
, in which the
reticulation of the siphunculi is confined to the
basal region. The genus occurs from Japan to
Eastern Australia and from India to the Philippines
(Blackman & Eastop 1994, 2006; Sugimoto
2008). They are mainly tree-living aphids and
their biology is little known and sexual forms are
generally unrecorded.
