Daphnella (Eubela) imparella Dall, 1908 Xanthodaphne imparella is a species of sea snail, a marine gastropod mollusk in the family Raphitomidae.

(Original description) The small, translucent white shell is smooth, polished, very thin, with a three-whorled yellow protoconch of the " Sinusigera " type, ending abruptly.

The whorls are gently rounded, with about four whorls following the protoconch, marked only with lines of growth, obscure spiral markings, and on the siphonal canal a few obsolete spiral threads.

The columella is straight, obliquely truncate in front, hardly callous.

[2] The holotype of this marine species was found off Azuero Peninsula, southeast of Punta Mala, Panama, North Pacific Ocean at a depth of 2323 m.
