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 .
