十八种石鳖属轻石鳖存在于澳大利亚和新西兰水域。beuileptochiton n. sp.和L. marshalli n. sp.作为新科学介绍。laurae和l.c.a opiparus是首次在新西兰海域记录到的。目前的材料允许获得关于唯美者数量的新信息，腰带电枢以及关于几个物种的radula形态。观察到南极细石蚧瓣形的相当大的变异性，导致考虑L. deecresswellae是该物种的低级同义。18种轻石类中有9种在新西兰附近发现，9种属于澳大利亚地区。可能除了阿皮帕蚊外，这两个地区没有任何共同的物种。
Eighteen species of the chiton genus Leptochiton are present in Australian and New Zealand waters. Leptochiton beui n. sp. and L. marshalli n. sp. are introduced as new to science. Leptochiton laurae and L. cf. opiparus are here recorded for the first time from New Zealand waters. The present material allowed to obtain new information about the number of aesthetes, the girdle armature as well as about the radula morphology in several species. A considerable variability in the valve shape of Leptochiton subantarcticus was observed leading to the consideration of L. deecresswellae being a junior synonym of this species. Nine of the eighteen Leptochiton species are found around New Zealand and nine belong to the Australian region. With the possible exception of L. opiparus, both regions do not share any species.
