Galls of Cerataphis bambusifoliae (Hemiptera, Aphididae) found on styrax suberifolius in Taiwan

Hitherto unknown fig-shaped galls of a cerataphidine aphid were found on Styrax suberifolius in a mountainous region of Taiwan. The morphology of 1st-instar nymphs deposited by alates that had emerged from the galls accorded well with the morphology of 1st-instar nymphs of Cerataphis bambusifoliae on bamboo. The mitochondrial DNA sequences from the gall and bamboo aphids also supported the identity of the 2 generations. The gall-living aphids are therefore considered to be the primary host generation of C. bambusifoliae, and a description of the alates, apterous adults, and the 1st-instar nymphs is given. We also revealed that, like other cerataphidines, C. bambusifoliae produces many 2nd-instar, sterile soldiers in their galls. http://zoolstud.sinica.edu.tw/Journals/47.2/191.pdf.
