18. Scutellum strongly reticulate (a1), sublateral grooves present posteriorly, curving to meet anterior to scutellar apex. Clypeal margin (b1) distinctly convex and all funicular segments quadrate or broader than long (b2). Propodeum (c1) with strongly elevated median panels (median panels of propodeum raised sharply above supracoxal flange and areas lateral to plicae), bearing 1 lateral seta and forming tooth-like elevation at posterior corner. Extremely poorly known genus, very rare in Nearctic.
