Polyptichites is the perisphictacean ammonite genus from the Lower Cretaceous of Russia.
The shell is subinvolute and coarsely ribbed; ribs bifurcate or trifurcate mid or low on the flanks and cross over the rounded venter.
The umbilicus is relatively small and deep.
Outer whorls partially envelop the previous leaving a fairly deeply impressed dorsum.
