ABSTRACT The systematics of the arboreal sesarmid crab genera Labuanium Serène and Soh, 1970 and Scandarma Schubart, Liu and Cuesta, 2003 is revised. Also included is the poorly known genus Namlacium Serène and Soh, 1970, which is morphologically similar to Labuanium and may also be arboreal in habit. The present study restricts Labuanium to its type species, L. politum (De Man, 1887), and congeners are transferred to Scandarma, Geosesarma De Man, 1892, and three new genera established herein: Circulium gen. nov., Shinobium gen. nov. and Mindanium gen. nov. Two new species of Scandarma are described from Papua New Guinea and Madagascar. Sesarma jacquinoti Ortmann, 1894, previously regarded as a synonym of Scandarma gracilipes (H. Milne Edwards, 1853) (comb. nov.), is here shown to be a junior synonym of Sesarmops angustifrons (A. Milne-Edwards, 1869). Labuanium schuetteii (Hess, 1865) is regarded as conspecific with Scandarma gracilipes (H. Milne Edwards, 1853) (comb. nov.) and the lectotype of the latter species (here designated) is also selected as the neotype of the former, making the two names objective synonyms. Material which had been identified as ‘Labuanium finni Alcock, 1900’ by Pretzmann (1984) from the South Andaman Islands is actually the poorly known Geosesarma thelxinoe (De Man, 1908), which is here referred to a new genus, Andamanium gen. nov. Sesarma finni Alcock, 1900 s.s. is herein assigned to Scandarma. Namlacium crepidatum (Calman, 1925), the only species in the genus, is redescribed and figured and compared with Labuanium and Scandarma. Keys to species of Circulium and Scandarma are provided. http://www.zoobank.org/urn:lsid:zoobank.org:pub:414B8DAA-584F-4070-A355-83B583D0D017

1970 年修订了海蟹属 Labuanium Serène 和 Soh，2003 年 Scandarma Schubart、Liu 和 Cuesta 以及 Namlacium Serène 和 Soh，1970 年（甲壳纲：十足目：Brachyuura：Sesarmidae），描述了四个新属和两个新物种

摘要 树栖海蟹属 Labuanium Serène 和 Soh 的系统学，1970 年和 Scandarma Schubart、Liu 和 Cuesta，2003 年进行了修订。还包括鲜为人知的 Namlacium Serène 和 Soh 属，1970 年，它在形态上与 Labuanium 相似，也可能是树栖习性。本研究将 Labuanium 限制为其模式物种 L. politum (De Man, 1887)，并将同源物转移到 Scandarma、Geosesarma De Man, 1892 和此处建立的三个新属：Circulium gen。十一月，Shinobium gen。十一月 和Mindanium gen。十一月 描述了来自巴布亚新几内亚和马达加斯加的两种新的 Scandarma 物种。Sesarma jacquinoti Ortmann, 1894, 以前被视为 Scandarma gracilipes (H. Milne Edwards, 1853) (comb. nov.) 的同义词，此处显示为 Sesarmops angusifrons (A. Milne-Edwards, 1869）。Labuanium schuetteii (Hess, 1865) 被认为与 Scandarma gracilipes (H. Milne Edwards, 1853) (comb. nov.) 同种，而后者的选型（此处指定）也被选为前者的新型，使得这两个名字客观的同义词。来自南安达曼群岛的 Pretzmann (1984) 鉴定为“Labuanium finni Alcock, 1900”的材料实际上是鲜为人知的 Geosesarma thelxinoe (De Man, 1908)，这里指的是一个新属，Andamanium gen。十一月 Sesarma finni Alcock, 1900 ss 在此指定给 Scandarma。Namlacium crepidatum (Calman, 1925) 是该属中唯一的物种，被重新描述和计算，并与 Labuanium 和 Scandarma 进行比较。提供了 Circulium 和 Scandarma 物种的关键。http://www.zoobank.org/urn:lsid:zoobank.org:pub:
