The phygadeuontine genus Chrysocryptus (Ichneumonidae) is reviewed for the first time on the basis of ichneumonid collections in the Institute of Ecology and Biological Resources, Hanoi (Vietnam), the Natural History Museum, London (UK), and the Naturalis Biodiversity Center, Leiden (the Netherlands). A new species, Chrysocryptus brevis, is described from northern Vietnam. In addition, C. aureopilosus is recorded for the first time from Vietnam and from Indonesia (West Java). A key to all four known species of the genus Chrysocryptus is included.
