Shape: visually transverse, Sides: straight, Maximal width: at posterior margin, Anterior margin: narrower than posterior. Anterior lobe Development: obvious, Shape: arcuate, Width: broad, Position: at level with anterior angles. Posterior angles Shape: rectangular, Apex: sharp. Disk Impressions: medial and lateral, Medial impression: entire, Lateral impressions (depth): deep, Lateral impressions (width): broad.

Lateral carinae Interspace: narrow, Convergence: moderate, Junction: present, Narrowest point: at posterior 1/5–1/4 of marginal carina. ELYTRA. Color: unicolored, Humeral carina: absent. Apices Arrangement: separate, Shape: arcuate, Modifications: margin obviously denticulate. Tomentum Pairs of tomentose spots: humeral, medial, apical. Pubescence Color: unicolored. STERNUM. Pubescence Strip of erect pubescence: absent. Prosternal lobe Size: large, Distal margin: subtruncate. Prosternal process Width: wide, Shape: subparallel, Sides: straight, Angles: obtuse, Angles (tips): blunt, Disc: flat, Projection (length): protruding distinctly beyond angles. Metasternum Metasternal projection: impressed. ABDOMEN. Basal ventrite Modifications: without modifications. Pygidium Apical margin: arcuate. Sternal groove Extent: on all ventrites, Shape on apex of last ventrite: arcuate. LEGS. Metatarsus Length to metatibia: distinctly shorter. Metatarsomere 1 Length to following tarsomeres: longer than 2–3 but shorter than 2– 4. GENITALIA. Aedeagus Symmetry: symmetric, Shape: subparallel.

Variability. Size: 6.1–7.5 mm. Sexual dimorphism. Female unknown. Aedeagus (Fig. 3A).

Diagnosis. Agrilus cultus sp. nov. and A. bacchus have subparallel sides of pronotum. The former is distinctive by slender body and narrower elytral apex.
