See text Clathurina Melvill, 1917 Kermia is a genus of sea snails, marine gastropod mollusks in the family Raphitomidae.

They form together a genus-complex with a highly underestimated diversity, leading to intermixed clades.

The lack of morphologic criteria requires the generic assignment of several species clearly to be reconsidered.

The shell structure is reticulate with glossy nodules on the intersections of the ribs and lirae.

The U-shaped or linguiform anal sinus is deep, located near the suture and is surrounded by a thick outer lip.
