Diagnoza

Distinguished from related species by the projection of the quadrate behind the posterior margin of the skull roof, and the presence of a shagreen of denticles on the palate.

Porównanie

C. intermedius differs from C. mordax in that the posterior border of the skull is more concave, though less so than in C. robustus. The orbits are in a more lateral position than in C. robustus, and the sides of the postorbital skull are more vertical. The interchoanal tooth row differs from that of C. robustus in being gently curved posteriorly (straight in C. robustus), while the para- and interchoanal teeth are broadly separated (single arcade in C. robustus). C. intermedius differs from C. posthumus Fraas, 1913, in that the lateral borders of the skull are straight rather than concave, while the choanae are oval (round in C. posthumus). The snout is broad in C. intermedius but slender in C. hemprichi Kuhn, 1942, while the anterior palatal vacuity is reniform, not oval as in C. ebrachensis Kuhn, 1932.
