The genus Wolffogebia was established in 1982 by Sakai, and species that have been included in it are discussed. A revised diagnosis is presented. Abundant material from Vietnam belonging to a new species of Wolffogebia is described. Wolffogebia nhatrangensis n. sp. is compared to its congeners. It differs in having small teeth on the lateral rostral borders, an unarmed distal rostral border and a spinule on the antero-lateral border of the carapace. Also, adult males bear eight to 12 oblique crests on the mesial surface of the pereiopod 1 propodus.
