Based on examination of all available types and a large number of additional specimens, the poorly studied genus Macronotops Krikken, 1977 is revised. Thirteen species are recognized, including four new species herein described, M. biserratus Qiu, Xu Chen, new species from Laos, M. dianensis Qiu, Xu Chen, new species from China (Yunnan) and Vietnam, M. miksici Qiu, Xu Chen, new species from China (Yunnan), Myanmar, and India, and M. medogensis Qiu, Xu Chen, new species from China (Xizang). The neotype of Macronota fulvoguttata Fairmaire, 1891 is designated. Macronotops fulvopilosus (Fairmaire, 1894) is considered as an independent species, and M. olivaceofuscus (Bourgoin, 1916) revised status, formerly regarded as subspecies of M. vuilleti (Bourgoin, 1916), is elevated to species rank. Pleuronota subsexmaculata Ma, 1992, new synonym and P. hefengensis Ma, 1992, new synonym are placed as junior synonym of M. olivaceofuscus and M. fulvoguttatus, respectively. All previous records of M. sexmaculatus (Kraatz, 1894) in southern China are verified as misidentification of M. olivaceofuscus; M. sexmaculatus is recorded from China (Xizang) for the first time, and its distribution appears to be limited to the southern side of the eastern Himalayas. Macronotops olivaceofuscus and M. vuilleti are newly recorded from Vietnam and China, respectively. Sima of Myanmar, the type locality of M. ovaliceps (Arrow, 1941), is located at the border of Myanmar and China (Yunnan); and more specimens of this species were obtained from western Yunnan. Habitus and diagnostic characters are illustrated for all species. Key to species and notes on natural history of this genus are also provided.
在对所有现有种类以及大量补充标本进行研究的基础上，对研究较少的Macronotops属（克里肯，1977年）进行了修订。共确认了13个物种，包括本文描述的4个新物种，即来自老挝的双锯Macronotops biserratus Qiu、Xu Chen新物种，来自中国（云南）和越南的滇Macronotops dianensis Qiu、Xu Chen新物种，来自中国（云南）、缅甸和印度的米氏Macronotops miksici Qiu、Xu Chen新物种，以及来自中国（西藏）的墨脱Macronotops medogensis Qiu、Xu Chen新物种。指定了1891年的黄斑Macronota fulvoguttata Fairmaire的新模式标本。黄斑Macronotops fulvopilosus（Fairmaire，1894年）被视为一个独立物种，而橄榄褐Macronotops olivaceofuscus（布尔戈因，1916年）的修订地位（以前被视为vuilleti Macronotops vuilleti（布尔戈因，1916年）的亚种）被提升为物种等级。1992年的亚六斑Pleuronota subsexmaculata Ma新异名和1992年的鹤峰Pleuronota hefengensis Ma新异名分别被列为橄榄褐Macronotops olivaceofuscus和黄斑Macronotops fulvoguttatus的次异名。中国南方以前所有的六斑Macronotops sexmaculatus（克拉茨，1894年）记录均被证实是对橄榄褐Macronotops olivaceofuscus的误认；六斑Macronotops sexmaculatus首次在中国（西藏）被记录，其分布似乎仅限于东喜马拉雅山脉的南侧。橄榄褐Macronotops olivaceofuscus和vuilleti Macronotops vuilleti分别首次在越南和中国被记录。缅甸的司马，即椭圆头Macronotops ovaliceps（阿罗，1941年）的模式产地，位于缅甸与中国（云南）的边境；并从云南西部获得了该物种的更多标本。文中为所有物种绘制了形态图和鉴别特征图。还提供了物种检索表以及该属的自然史记录。
