Anacithara platycheila is a species of sea snail, a marine gastropod mollusk in the family Horaiclavidae.[1]
The length of the ovate, dirty white shell attains 6.5 mm, its diameter mm. It contains whorls. The outer lip is conspicuously thin, very dilated laterally and slightly sinuate on top. The columella has a slight callus. The open siphonal canal is very short. The single reddish-brown band around the body whorl and the broadly expanded lip at once mark the distinctness of this species. The maculations near the suture are about three on a whorl.[2]
