is described from the Tibetan Plateau near Kangding, Sichuan, China. It is a member of the subgenus Helophorus s. str. but the anterolateral part of the pronotum resembles subgenus Gephelophorus Sharp, 1915. The short metallic-black maxillary palpi with almost symmetrical apical segments are suggestive of subgenus Kyphohelophorus Kuwert, 1886, but the elytral flanks are narrower than the epipleurs, excluding the species from that subgenus. An adjusted key to s. str. is given to identify the new species, as well as Angus, 1995 and Zaitsev, 1908.
它是在中国四川康定附近的青藏高原被描述的。它是Helophorus属狭义亚属的成员，但前胸背板的前侧部分类似于Gephelophorus Sharp属（1915年）。短的金属黑色下颚须，其顶端节段几乎对称，这让人联想到Kyphohelophorus Kuwert属（1886年），但鞘翅侧面比侧缘更窄，这将该物种排除在该亚属之外。给出了一个狭义亚属的修订检索表，用于识别新物种，以及安格斯（1995年）和扎伊采夫（1908年）的相关内容。
