Thorax subspherical, well developed, having 20-30 irregularly arranged subcircular pores. Third segment conical, longer and broader than any other, bearing two kinds of pores: ordinary small pores on the whole surface and a single row of pores twice as large as the others just below the lumbar stricture. Fourth segment generally ragged with smaller pores irregularly arranged. Entire apertural margin never observed.
