Sphegigastrini

Sphegigaster Sphegigastrides Thomson, 1876. Type genus: Sphegigaster Spinola, 1811.

Diagnosis.

Clypeal margin symmetrical or asymmetrical, with 2 or 3 denticles or uniformly convex (Fig. 96 ). Mandibles not enlarged. Petiole usually elongate (exception: Tricyclomischus Graham), with anterolateral flange that extends anteriorly to flank petiolar insertion (Fig. 97 ), ventrally closed by the continuation of this flange.

Discussion.

The current concept of Sphegigastrini agrees with that presented by Heydon (1988). Specimens of Bairamlia fuscipes Waterston new placement were examined morphologically in the course of this study, and were found to belong unambiguously to Sphegigastrini based on the anterolateral petiolar carina. Other genera that we place in Sphegigastrini , based on molecules and/or morphology, are listed in Appendix I.
