Dorsal furrows narrow and deeply incised laterally, a little shallower in front of glabella; palpebral lobe of medium size, wituated at a position opposite to the mid-length of glabella. Posterior limb relatively small, triangular in shape. Preglabellar area long (sag.). Both anterior border and brim long (sag.). Anterior border subcrescentic-shaped, upturned towards anterior margin; a raised thread-like ridge parallel to the posterior margin which bears a row of about 30 hardly visible nodes, with two of them in the center more clearly defined. Anterior facial sutures diverging forwards at an angle of about 35° to the cranidial axial line, posterior facial sutures short.
