  1. Raphe slightly eccentric to the apical axis
  2. Distinct, regularly spaced fibulae
  3. Conopeum present
  4. Striae difficult to discern

The canal raphe is prominent, positioned slightly eccentrically. The raphe lacks a gap in the center at the proximal raphe ends. The fibulae are distinct and regularly spaced. A conopeum is recognizable under LM as two parallel lines, each running longitudinally on either side of the canal raphe. Striae count is high (32-50 in 10 µm), so striae may not be visible in the light microscope.
