Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| H. G. Johnson et al. 2000 | A small actinolepid in which the Pineal is fused to the skull. The Nuchal is approximately one half of skull roof length. A small segment of the profundus canal on the Postorbital branches off the intersection of the central sensory line with the infraorbital sensory line. The occipital cross commissure is present on the Paranuchal only. The posterior pit line is present on the Paranuchal and Central, but individual segments do not connect. The Centrals and Marginals are in direct contact. The Median Dorsal is short and broad (B/L index 87–96). A Posterior Median Dorsal is present. The exposed surface of the Anterior Dorsolateral is narrow and transected by the lateral line canal in an anterior-posterior direction. The Anterior Lateral is broad dorsally and narrow ventrally with a narrow inner wing. The Spinal is long and extends approximately 33% beyond the distance of the Anterior Ventrolateral lower margin. The Anterior Ventral is small. |
