 from above nearly square, a little broader than long, a little broader 

 than the petiole through its posterior teeth, feebly convex above, 

 sharply truncated anteriorly, ventrally with a stout angular projection 

 followed by a prominent transverse welt. Gaster narrow, twice as 

 broad as the postpetiole, two and one-half times as long as broad, 

 flattened dorso ventrally, the first segment as long as broad. Legs 

 short, shaped much as in greeni, with apically dentate posterior tibiae
