Phorodon viburni Matsumura (1918)

was collected from the underside of leaves of Viburnum sp. ( Caprifoliaceae ) at the Botanical Garden of the Agricultural College of Hokkaido in mid-July. Only alatae and alatoid nymphs were found. This species has not been found since the original description ( Blackman and Eastop 2006). More study, and likely more collection records, are needed to determine the status of this species. The host relationship is unusual for Phorodon .
