Seven species of the subgenus Duolandrevus (Eulandrevus) Kirby, 1906 have been recorded from China prior to this study. Their morphology is similar, and genitalia can be used for distinguishing different species in earlier research. We describe one new species, D. (E.) obsidianus He sp. nov. from Guangxi. The new species is similar to related species in gross morphology, but showed differences in genitalia with epiphallic lateral lobes bifurcated apically in right angle. The songs and COI genes are first compared in this study, and the results support the validity of the new species. The type specimens are deposited in Museum of Biology, East China Normal University (ECNU).
在本研究之前，中国已记录到1906年柯比（Kirby）所定多兰瑞乌斯亚属（真兰瑞乌斯亚属）的7个物种。它们形态相似，在早期研究中，生殖器特征可用于区分不同物种。我们描述了一种来自广西的新物种，即黑曜石多兰瑞乌斯（真兰瑞乌斯亚属）（D. (E.) obsidianus He）新种。该新物种在总体形态上与相关物种相似，但生殖器存在差异，阳茎侧叶顶端呈直角分叉。本研究首次对鸣声和COI基因进行了比较，结果支持该新物种的有效性。模式标本保存于华东师范大学生物博物馆（ECNU）。
