Eustenogaster nigra Saito and Nguyen , in Saito et al., 2006: 2.

Eustenogaster nigra differs from other species of the genus in having the second metasomal tergum strongly convex dorsally (Figs. 17, 18). The condition in E. scitula approaches to that of E. nigra , but E. nigra is easily distinguished from E. scitula by the yellow spots on the clypeus ( Figs. 57 ), upper part of mesopleuron, scutellum, metanotum and propodeum, all absent.
