| Size under dissecting microscope: 250µm Size under compound microscope: 245µm |
| Morphology: Pachydermia laevis has a moderately large protoconch with regular overall interconnected reticulate sculpture, strongly marked in the proximal region and becoming finer and less distinct toward the aperture. The aperture is slightly curved with a thickened broad rim that tapers slightly toward the inner edge. |
| Frequency: Pump EPR 1999-2000: Frequent Pump EPR 2004: Frequent Trap EPR 2004-2005: Occasional |

Pachydermia laevis is most likely to be confused with Unknown neomphalid W, as they are approximately the same size and both have reticulate sculpture. However, Unknown neomphalid W lacks the thickened aperture rim and its sculpture is coarser and less regular and is limited to the proximal half of the shell. |
