ABDOMEN. Basal ventrite. Modifications: absent. Pygidium. Apical margin: arcuate. Sternal groove. Shape on apex of last ventrite: arcuately sinuate. LEGS. Metatarsus. Length to metatibia: distinctly shorter. Metatarsomere 1. Length to following tarsomeres: subequal or longer than 2–4. GENITALIA.

Ovipositor. Shape: markedly elongate.

Variability. The species is known only from the female holotype. Sexual dimorphism. Females with an elongate ovipositor.

Diagnosis. Agrilus zim sp. nov. is similar to A. mimicus sp. nov. ( Fig. 4A ) by the elongated pronotum, by the strongly arcuate carinal prehumerus, and by the bicolored elytral pubescence. It differs by having the anterior end of the prehumerus joined with the lateral pronotal carina, by the separately subarcuate elytral apices, by the arcuate anterior margin of the sternal lobe, and by the subparallel sternal process.
