琉球列島から知られ、センダングサ類の花に普通に見られる。カリブ海沿岸原産で、ハワイ、台湾にも分布する。ミカンキイロアザミウマに似るが、触角第2節は背方に突出し、2本の刺毛が太いこと、腹部第8背板の後縁は中央部で櫛歯状突起を欠くことで識別できる。

This species is common on the flowers of Bides (Asteraceae) in the Ryukyu Islands, southern Japan. It originated in the Caribbean and is also found in Hawaii and Taiwan. It is similar to F. occidentalis but can be distinguished by the dorsal projection on antennal segment II, which bears two stout setae, and by abdominal tergite VIII, which lacks a posteromarginal comb medially.
