The imaginal stages and eggs of the species Labiobaetis ancoralis Shi and Tong (2014) are first described and photographed based on reared materials from mature nymphs. In addition, its COI gene is sequenced and compared to other species in the same genus. Besides its nymphal labrum with submarginal spatulate-like bristles, abdomen with anchor-shaped markings, its imaginal diagnostic characteristics include slim hindwings with an indistinct costal process, and a cone-like projection between two base-widened forceps. The COI gene sequence of this species is close to L. atrebatinus. The morphological details provided in this research show that the males of the species L. ancoralis, like typical baetids, have reduced hindwings and penes, which have very limited value in classification, but their shapes of forceps can be used in future studies to identify the potentially diverse Chinese Labiobaetis species.
