Diagnosis. Agrilus chloros  sp. nov. is the only species of the Agrilus pilosotiabialis  species –group without discernible elytral pubescence. The species is distinctive by bright golden –green dorsal side; by conjointly arcuate elytral apices and by subparallel shape of aedeagus ( Fig. 5CView FIGURE5).
