| Reference | Diagnosis | |
|---|---|---|
| Z. Johanson 1998 | Differs from all other Bothriolepis in possessing a reduced anterior process of the submarginal, separated from the posterior process of the submarginal by a wide, open notch. Characterised by: Preorbital recess trifid. Oval attachment area for prelateral on the lateral plate small, laterally oriented, separated from a strongly developed, horizontal anterior submarginal attachment on the lateral plate. Posterior submarginal attachment on lateral plate ending at posterior margin of spiracular groove. Pineal plate with reduced posterolateral corners. Postlevator cristae of anterior median dorsal plate sharply defined and short, often dissociated from the postlevator thickenings and situated in the levator fossa. Crista transversalis interna anterior on anterior ventrolateral plate obliquely oriented. Cv2 and Mml plates do not overlap on mesial margin of pectoral fin. |
