Systropha punjabensis (subfamily Dufoureinae), an exceptionally small species, is morphologically unlike either Systropha s. str. or Systrophidia. A nest had 4 oval cells, 2 of them at the ends of lateral burrows, arranged along a nearly vertical main burrow. Cells did not have a glossy waterproof lining. The larva, morphologically similar to that of Rhophites, probably makes a cocoon.
