One elongated stigma present, positioned in between the proximal raphe endings and the valve face margin (Fig. 3X-Z). Ghost areolae often present, mainly on a stigma-bearing site (Fig. 3X, AA). Raphe branches straight. Externally, proximal raphe endings deflected away from the isolated pore-bearing side with small drop-like endings (Fig. 3AB). Terminal raphe fissures clearly elongated, first curved to the same side as the proximal raphe fissures, then slightly bent to the isolated pore-bearing side. Terminal raphe fissures are towards the valve apices, terminating on the valve face/mantle junction, well after the final row of areolae (Fig. 3AC). Valve mantle bearing a single row of rounded areolae (Fig. 3Z, AA). Copulae with single row of areolae (Fig. 3AA). Internally, areolae occluded by hymenes, forming a continuous strip across each stria (Fig. 3AD-AF). Internal isolated pore opening rounded, covered by a lipped slit. Proximal and terminal raphe endings weakly deflected towards the pore (Fig. 3AE), the latter terminating on to small helictoglossae (Fig. 3AF). Longitudinal channel visible along valve edges (Fig. 3AE, AF).</p></div> 	http://treatment.plazi.org/id/51AA4AE45DEE5A58B7D5E9EAEB519091	Public Domain	No known copyright restrictions apply.
