In this article, I describe a new endemic genus of New Caledonian Eumolpinae, Kumatoeides gen. nov. (tribe Eumolpini), and eight new species currently conforming the genus: K. anomala sp. nov., K. aulacia sp. nov. (generic type), K. leptalei sp. nov., K. megale sp. nov., K. metallica sp. nov., K. millei sp. nov., K. tarsalis sp. nov. and K. wanati sp. nov. Some easily recognizable defining traits of this new genus of fairly small species (2.23-3.20 mm) are the glabrous dorsum, aligned punctures on elytra in eight regular striae plus short scutellar and a subhumeral striae, convex elytral intervals, and the enlarged and elongate first pro- and mesotarsomeres of males. One species originally described in the genus Montrouzierella Jolivet, Verma et Mille is transferred to the new genus as Kumatoeides costata (Jolivet, Verma et Mille) nov. comb. A preliminary phylogenetic analysis using partial cox1 and rrnS mtDNA sequences of five species of Kumatoeides gen. nov. together with a representative sample of species of Eumolpinae from New Caledonia supports the monophyly of the genus and the existence of two main groups as recognized based on morphological traits. However, data are not conclusive about the relationship of the new genus with other New Caledonian lineages, although suggest a closest relationship with some unidentified species most similar to some representatives of the genus Samuelsonia Jolivet, Verma et Mille but with morphological similarities with Kumatoeides gen. nov., including dilated male protarsomeres, similar antennomere proportions and tendency to aligned rows of punctures on elytra, at least apically.
在本文中，我描述了新喀里多尼亚叶甲亚科的一个新的特有属——库马叶甲属（Kumatoeides gen. nov.）（叶甲族），以及目前归入该属的八个新物种：异形库马叶甲（K. anomala sp. nov.）、奥拉西亚库马叶甲（K. aulacia sp. nov.）（模式种）、莱普塔莱库马叶甲（K. leptalei sp. nov.）、巨库马叶甲（K. megale sp. nov.）、金属库马叶甲（K. metallica sp. nov.）、米勒库马叶甲（K. millei sp. nov.）、跗节库马叶甲（K. tarsalis sp. nov.）和瓦纳蒂库马叶甲（K. wanati sp. nov.）。这个新属的一些易于识别的特征是：这些相当小的物种（体长2.23 - 3.20毫米）的背面无毛；鞘翅上有排列成八条规则纵沟的对齐小孔，还有短的小盾片沟和一条亚肩沟；鞘翅间隔凸起；雄性的第一跗节和中跗节膨大且延长。一个最初被描述在蒙特鲁齐叶甲属（Montrouzierella Jolivet, Verma et Mille）的物种被转移到新属，成为肋纹库马叶甲（Kumatoeides costata (Jolivet, Verma et Mille) nov. comb.）。使用库马叶甲属五个物种的部分细胞色素氧化酶亚基1（cox1）和rrnS线粒体DNA序列以及新喀里多尼亚叶甲亚科物种的代表性样本进行的初步系统发育分析，支持了该属的单系性以及基于形态特征所识别的两个主要类群的存在。然而，关于这个新属与新喀里多尼亚其他谱系的关系，数据并不确凿，不过表明它与一些未鉴定物种关系最为密切，这些未鉴定物种与萨缪尔叶甲属（Samuelsonia Jolivet, Verma et Mille）的一些代表最为相似，但在形态上与库马叶甲属有相似之处，包括雄性跗节膨大、触角节比例相似以及鞘翅上小孔排列成行的趋势（至少在顶端）。
