(B.) rhynchoptera in the phylogeny tree, but it can be distinguished from the latter by the following male characters: (1) without hair tuft / short setae between 1 st and 2 nd abdominal ventrites (with hair tuft / short setae between 1 st and 2 nd abdominal ventrites in B. (B.) rhynchoptera); (2) lateral margin of pronotum weakly broading from base to 2 / 3, then toward anterior angles arcuated, widest before middle (pronotum widest at middle in B. (B.) rhynchoptera). Additionally, the new species is morphologically similar to B. (B.) japonensis Marseul, 1879 but can be distinguished from the latter by the following male characters: (1) without hair tuft / short setae between 1 st and 2 nd abdominal ventrites (with hair tuft / short setae between 1 st and 2 nd abdominal ventrites in B. (B.) japonensis); (2) lateral margin of pronotum broading from base to 2 / 3, then toward anterior angles arcuated, widest before the middle (lateral margin of pronotum arcuated, widest at middle in B.

A5BDC7099C4258BA87B5E639B4A21855.taxon	etymology	Etymology. This species is named from the Latin adjective “ undulata ”, meaning wavy, in reference to the wavy wrinkles on the elytra.	en	Zhang, Bao-Yue, Li, Xiu-Min (2025): Phylogeny-based reinterpretation of the genus Blaps Fabricius, 1775 (Coleoptera, Tenebrionidae, Blaptinae) from China, with description of two new species.
