This species is likely Xenohammus griseomarmoratus Breuning, 1956. LIN M. & YANG X., 2026, in *Descriptions of five new species of Longicornia from South China*, write that this species does not belong to the genus Xenohammus Schwarzer, 1931, just like Xenohammus guangdongensis Lin & Yang, 2026. I understand from the published article that the authors saw a photograph of a paratype of X. griseomarmoratus Breuning, 1956.
It seems to me that in VIVES i NOGUERA E., 2026.Longicornios nuevos o interesantes de Vietnam (Pars-14) Figure 2 shows this species, but under the name Annamanum griseomaculatum Breuning, 1936.In my opinion, the holotype of A. griseomaculatum is a completely different species, and E. Vives is mistaken.
This species has been posted several times on the forum, but the quality of the photos doesn't allow me to confirm that it's the same one. See here, here, and here.
