Otitoma timorensis is a species of sea snail, a marine gastropod mollusk in the family Pseudomelatomidae.

(Original description) The shell is elongately fusiform, strong and reddish brown.

Moreover, the shell is covered with fine spiral striae and growth lines, and is crossed by thick, rounded, oblique ribs, 12 in number on the penultimate whorl, which give the shell an elegantly beaded appearance.

The columellar margin is concave above, rather straight below, with a strong layer of enamel.

[2] This marine species is endemic to Indonesia and is found off Timor.
