''Liotella anxia'' is a species of minute sea snail, a marine gastropod mollusc in the family Skeneidae.〔Marshall, B. (2013). Liotella anxia (Hedley, 1909). Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=719444 on 2013-10-25〕 ==Description== (Original description by Ch. Hedley) The height of the shell attains 0.7 mm, its diameter 1.1 mm. The minute, depressed, pale buff shell has a turbinate shape and is widely umbilicate. The three whorls increase rapidly in size and are loosely coiled. The final half-whorl descends and departs from the remainder. The sculpture shows fine radial threads that traverse the whole shell. There are about sixty of these on the body whorl. Their interstices are closely latticed by rather finer spirals. The simple aperture is free and circular. The broad umbilicus is deep.〔(Ch. Hedley (1909), ''Mollusca from the Hope Islands, north Queensland''; Proceedings of the Linnean Society of New South Wales v. 34 (1909) ) (described as ''Liotia anxia'')〕
