Benthomangelia celebensis is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae.

(Original description) The small shell has a subbiconical shape with a short siphonal canal and a subgradate spire.

The subsequent whorls are angular, excavated above, separated by a conspicuous, irregularly waved suture, with a rather strong rib just below it, with short bead-like folds.

The aperture is elongately oval, angular above, with a short, wide siphonal canal below.

The peristome is thin, broken, according to growth lines with a wide, rather deep sinus above, then considerably protracted, columellar side concave above, slightly tortuous below, with a conspicuous, appressed layer of enamel.
