Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J.-C. Rage et al. 2008 | "Differs from Russellophis tenuis and Krebsophis thobanus Rage and Werner, 1999 in having a narrower and thicker zygosphene. Further differs from R. tenuis by its more massive build, larger cotyle and condyle, and more dorsally placed paradiapophyses. Further distinguished from K. thobanus by its lamellar and high neural spine, paradiapophyses more extended dorsoventrally, thinner roof of zygantrum, and by the continuity between ventral edge of parapophyses and subcentral ridges." (Rage et al., 2008: 395). |
