Leptothyra is a genus of sea snails, marine gastropod mollusks in the family Colloniidae.[2]
This genus was previously placed in the family Turbinidae.
The name Leptothyra is generally attributed to Pease (1869), and the name "Leptothyra Pease, 1869" is usually treated as a valid name for small colloniines. Although Leptothyra is a junior objective synonym of Homalopoma, the species usually treated as valid in that genus are provisionally listed in WoRMS under "Leptothyra sensu Pease, 1869", pending a taxonomic/nomenclatural reappraisal.[2]
Leptothyra J. G. Cooper, 1867 is now considered a junior objective synonym of the genus Homalopoma Carpenter, 1864 [3]
The small, solid shell has a turbinate or globose shape. The operculum is multispiral with a subcentral nucleus and concave in the centre outside. The main character distinguishing Collonia from Leptothyra seems to be the peculiar peristome of the former.[4]

鱗窗螺屬（学名：Leptothyra）是一種微小貝尺寸[2][3]海螺的屬。本屬舊屬原始腹足目蝾螺科[4]，今屬鐘螺總科縮口螺科[5]，其物種有鈣質的口蓋（英语：operculum (gastropod)）。
鱗窗螺屬的學名Leptothyra曾被多次使用，不同時期不同人的定義都有不同的處理。現時提及Leptothyra時，一般都會指Pease (1869)定義的縮口螺類成員[5]。
鱗窗螺屬物種有着堅實的微型壳体，略呈球形、卵圆形或陀螺形；具脐孔，狭窄型或较小圆形[3]。口蓋（英语：Operculum (gastropod)）有多重螺旋，有一個中心以外的核，口蓋朝外一邊的中心凹陷。殻口的型態是分辨本屬與缩口螺属物種的主要特徵[6]。
本屬包括下列各物種[5]
