While the leaf insects (Phylliidae) are a well-supported group within Phasmatodea, the genus Illiger, 1798 has repeatedly been recovered as paraphyletic. Here, the Phyllium (Phyllium) celebicum species group is reviewed and its distinctiveness from the remaining Phylliini genera and subgenera in a phylogenetic context based on morphological review and a phylogenetic analysis of three genes (nuclear gene 28S and mitochondrial genes COI and 16S) from most known and multiple undescribed species is shown. A new genus, , is erected to partially accommodate the former members of the species group. Two species, Hennemann et al., 2009 and Lit & Eusebio, 2014 morphologically and molecularly do not fall within this clade and are therefore left within Phyllium (Phyllium). The transfer of the remaining group members from Illiger, 1798 to this new genus creates the following new combinations; (Westwood, 1859), ; (de Haan, 1842), ; (Seow-Choen, 2017), ; (Yang, 1995), ; (Cumming & Le Tirant, 2020), ; (Liu, 1993), ; (Liu, 1993), ; (Liu, 1993), ; (Wood-Mason, 1875), ; (Cumming & Teemsma, 2018), ; and (Liu, 1993), The review of specimens belonging to this clade also revealed 13 undescribed species, which are described within as: from Vietnam: Quang Nam Province; from Vietnam: Quang Ngai, Thua Thien Hue, Da Nang, Gia Lai, Quang Nam, and Dak Nong Provinces; from Vietnam: Ninh Thuan Province; from China: Yunnan Province; from Indonesia: Wangi-wangi Island; from Vietnam: Quang Ngai and Lam Dong Provinces; from Vietnam: Lam Dong and Dak Lak Provinces; from Cambodia: Koh Kong and Siem Reap Provinces; from Vietnam: Lam Dong, Dak Lak, and Dak Nong Provinces; from China: Guangxi Province; from Vietnam: Ninh Thuan Province; from Vietnam: Dong Nai and Ninh Thuan Provinces; and from China: Yunnan Province. All newly described species are morphologically described, illustrated, and molecularly compared to congenerics. With the molecular results revealing cryptic taxa, it was found necessary for (Wood-Mason, 1875), to have a neotype specimen designated to allow accurate differentiation from congenerics. To conclude, male and female dichotomous keys to species for the are presented.
虽然叶螽（叶螽科）在竹节虫目中是一个得到充分支持的类群，但1798年的伊利格属（Illiger）多次被发现是并系群。在此，对塞氏叶螽（Phyllium (Phyllium) celebicum）物种组进行了综述，并基于形态学综述以及对大多数已知和多个未描述物种的三个基因（核基因28S和线粒体基因COI及16S）的系统发育分析，展示了其在系统发育背景下与其余叶螽亚科属和亚属的区别。建立了一个新属，以部分容纳该物种组的先前成员。两种物种，2009年亨内曼等人描述的和2014年利特与尤西比奥描述的，在形态和分子上不属于这个分支，因此仍留在叶螽属（Phyllium (Phyllium)）。将其余该组的成员从1798年的伊利格属转移到这个新属产生了以下新组合：（韦斯特伍德，1859年），；（德哈恩，1842年），；（萧氏，2017年），；（杨，1995年），；（卡明与勒蒂兰特，2020年），；（刘，1993年），；（刘，1993年），；（刘，1993年），；（伍德 - 梅森，1875年），；（卡明与蒂姆萨，2018年），；以及（刘，1993年），对属于这个分支的标本进行综述还发现了13个未描述的物种，在文中描述如下：来自越南广南省的；来自越南广义、承天顺化、岘港、嘉莱、广南和达农省的；来自越南宁顺省的；来自中国云南省的；来自印度尼西亚旺伊旺伊岛的；来自越南广义和林同省的；来自越南林同和达克拉克省的；来自柬埔寨国公和暹粒省的；来自越南林同、达克拉克和达农省的；来自中国广西省的；来自越南宁顺省的；来自越南同奈和宁顺省的；以及来自中国云南省的。所有新描述的物种都进行了形态描述、绘图，并与同属物种进行了分子比较。分子结果揭示了隐存分类单元，发现有必要为（伍德 - 梅森，1875年）指定一个新模式标本，以便与同属物种进行准确区分。最后，给出了该属物种的雌雄二分检索表。
