Asperdaphne

Asperdaphne is a genus of sea snails, marine gastropod mollusks in the family Raphitomidae.

==Description== This genus resembles Daphnella in form and general appearance, but differs in having the protoconch spirally grooved instead of being obliquely reticulated. The contour is lanceolate rather than oval. The shell has usually more whorls, increasing less rapidly, with a longer and more turreted spire. The anal fasciole is usually more marked than in Daphnella, being more excavate, and crossed by sharp crescentic riblets. Some members of this genus have a superficial resemblance to Defrancia, under which genus they have been arranged.
