Some species have also been introduced to East Asia. They are the most speciose radiation of the Unionidae, with more than 300 species.[1][2]
Fossils of this group date back to the Late Cretaceous.[3]

小方蚌亚科（Ambleminae） 是蚌科之下的一個亞科，其物種舊屬珠蚌亞科，與 隆嵴蚌亚科（Gonideinae[1]）關係密切[2]。其物種主要棲息於北美洲大陸。
根據WoRMS，本亞科包括43個屬[3]；但根據ITIS，這些屬都可以歸入下列四個族之一，合共53個屬[4]。連同於2017年描述的Parvaspina，這54個屬分別如下：
又，WoRMS紀錄有Carunculina Simpson in Baker, 1898這個屬，但之下的12筆都被認為是 Toxolasma（英语：Toxolasma） 跟 Villosa（英语：Villosa） 這兩個屬的六個物種的異名[13]。
