Clusters of dorsal oral-collar tubular ducts on thorax; clusters of oral collars laterad of anterior spiracle and mid coxa; translucent pores present on hind tibia; oral-rim tubular ducts present on dorsum and venter; 2 pairs of cerarii on abdomen.
Vryburgia viator is similar to V. succulentarum by having 2 pairs of cerarii, dorsal oral-collar tubular ducts, translucent pores on hind tibia only, few or no dorsal multilocular pores. Vryburgia viator can be distinguished (characters of V. succulentarum are in parentheses) by having dense clusters or oral-collar tubular ducts on the dorsum of the thorax (clusters absent) and oral-rim tubular ducts present on dorsum (absent).
This species was intercepted at U. S. ports-of-entry 13 times between 1995 and 2012, with specimens originating from Ghana, The Netherlands, South Africa, and Zimbabwe. We also have examined specimens taken in quarantine from The Netherlands (Leucodendron); Zimbabwe (Leucodendron). ScaleNet lists only one host, European crab apple, on which it is also most commonly intercepted. ScaleNet distribution records for V. viator include only Kenya. Several other species of Vryburgia other than V. amaryllidis (Bouché), V. distincta (De Lotto), V. succulentarum Williams and V. viator have been taken at U. S. ports-of-entry including: V. bechuanae (Brain) (South Africa, on “flower"); V. brevicruris McKenzie (The United Kingdom of Great Britain and N. Ireland, on Haworthia; South Africa, on Protea); V. rimariae Tranfaglia (Italy and New Zealand, on Echeveria); V. pretiosa Ferris (Burma, China, Cuba, and The Philippines, on bamboo); and V. trionymoides (De Lotto) (South Africa, on Euphorbia).
