The Gonioctena kanfani species-group of the nominotypical subgenus Gonioctena Chevrolat, 1836 is proposed and reviewed. This group comprises the following five species, including two new to science, distributed in eastern China and northern Laos: G. kanfani (Chen, 1941), G. kamikawai (Chj, 1958), G. fujiana Cho Borowiec, 2016, G. jolantae new species, and G. lukasi new species. Members of this species-group are easily distinguished from other species by their metallic lustre, two yellowish-brown markings on the elytral humeri, and the trifurcated tip of the flagellum of the aedeagus. Photographs of habitus, illustrations of male genitalia, and diagnostic characters for each species are given. A distribution map and literature records are also provided.
提议并审查了 Gonioctena Chevrolat, 1836 指名亚属的 Gonioctena kanfani 种组。该组包括分布在中国东部和老挝北部的以下五个物种，其中两个为新种：G. kanfani (Chen, 1941)、G. kamikawai (Chj, 1958)、G. fujiana Cho Borowiec, 2016、G. jolantae 新种和 G. lukasi 新种。该种组的成员因其金属光泽、鞘翅肩部的两个黄褐色标记以及阳茎触角的三叉状末端而易于与其他物种区分开来。给出了形态的照片、雄性生殖器的说明和每个物种的鉴别特征。还提供了分布图和文献记录。
