Lioglyphostoma aguadillanum is a species of sea snail, a marine gastropod mollusk in the family Pseudomelatomidae, the turrids and allies.

[1] There is one subspecies: Lioglyphostoma aguadillanum minor (Dall & Simpson, 1901) (exactly similar in sculpture, but of a pale-straw color, and is 8.5 mm.

It contains nine whorls of which the first three are nepionic, smooth and polished, the subsequent elegantly axially ribbed, with two to four primary spiral threads and a fine interstitial spiral striation, essentially as figured.

The shell is white with a superficial brownish tinge on the larger whorls, apex and interior of the outer lip of a delicate lilac.

The inner lip and the aperture are smooth or destitute of the denticulations usually found in Mangilia.
