dorsal areas of propodeum with at least one, more or less distinct, transverse secondary keel. (head from above distinctive, somewhat lentil-shaped; pronotum with prominent dentiform shoulders, its posterior face subvertical and rugose; posterior margin of pronotum showing as a free, raised rim that extends from spiracle to spiracle and is separated from the mesoscutum by a percurrent furrow; scutellar foveae circular; face with a dull shagreened sculpture that extends from the antennal insertions almost to the clypeus; marginalis only about one-fifth as long as its distance from the basalis.)
dorsal areas of the propodeum without transverse secondary keels. (Except in Belyta carinifrons Kieffer and Pantoclis brevicornis Kieffer, both of which have the marginalis much more than one-fifth as long as its distance from the basalis, the posterior margin of the pronotum is never raised as a free rim from spiracle to spiracle, being always more or less hidden in front of the lateral lobe of the mesoscutum by a flange-like extension of this)
