Similar to Xystodesmidae in having smooth dorsal tergites and keels (paranota) that are horizontal to slightly depressed, lacking serrations on lateral margin.
endemic to NA: Nebraska & central Illinois to southern Texas and eastward along the Gulf Coast to northern Florida (southward to Pasco Co.) and northward along the Atlantic Coast to southeastern North Carolina. (Rowland Shelley)
