From the very close Agrilus tonkineus, it can be distinguished by the flat pronotum; by the bi-sinuate prehumerus and by the presence of transverse tomentose strip at apical third of elytra. See also Appendix.

The specific name is Latin adjective mucidus (moldy). It refers to the elytral tomentum of the species.
