Original Description

Species subgeneris Paradiadesmis. Valvae stricte lineares in media parts parum inflatae apicibus late subcapitatis et late rotundatis, 20-35, longae, 3-4 μm latae. Raphe filiformis recta poris et nodulis terminalibus plus minusve valde de apicibus ad partem proximalem versus transferunt, itaque cum areis terminalibus angustis longs prolongatis.
