The gibba group of Chrysis occurs in many parts of the world. It is characterized in part by a lengthened clypeus. Other features are the usually long malar space, micro-ridging on the scapal basin, a frontal carina (when developed) with a broad M-shape and partial posterior rami (broadly biconvex in one species), tergum II apicolaterally obtuse, and tergum III with 4 teeth or lobes. American forms in the male, and to lesser extent the female, have long whitish hair beneath the head and on the opposing surface of the forecoxae. Other legs are also quite hairy, especially in males. Sternum VIII has ,the posterior one-half poorly developed and membranous.
