L. sulfurea was described from Amboina, Moluccas, on a single specimen, without mention of food plant. The variety rubrocincta was described from the Philippines as occurring on Calophyllum inophyllum , the young feeding beneath the rolled over edge of the leaves. The Guam specimens were reared from the same tree, and similarly situated on the leaves. They agree pretty well with the characters which Uichanco gives as distinctions between the variety and sulfurea , except that the Guam specimens lack the reel markings on the abdomen. Uichanco had one female in which these were not evident. He concludes: "When more is known about the Moluccan insect, the variety rubrocincta may finally have to be merged with the species."

The species didactyla described from Fiji in 1922, on Calophylluni inophyllum seems more likely to be the same as Guam material, especially on account of white lines on the thorax which are not mentioned in the description of sulfurea .

As Calophyllum inophyllum is widely spread in Pacific tropics, no doubt this psyllid will be found more widely spread when more collecting is done. The tree occurs in Hawaii, but does not have the psyllid.
