Shape: visually transverse; Sides: markedly arcuate; Maximal width: at middle; Anterior margin: subequal to posterior. Anterior lobe. Development: moderate; Shape: arcuate; Width: broad; Position: at level with anterior angles. Posterior angles. Shape: obtuse; Apex: blunt. Disk.

Interspace: narrow; Convergence: moderate; Junction: absent; Narrowest point: at posterior 1/5–1/4 of marginal carina; Modifications: submarginal carina anteriorly obliterate. Scutellum. Size: robust. ELYTRA. Humeral carina: absent. Apices. Arrangement: separate; Shape: cuspidate; Number of cusps or spines: 1; Position of dominant projection: pleural margin. Tomentum. Pairs of tomentose spots: humeral, medial, apical. STERNUM. Prosternal lobe. Distal margin: arcuately emarginate; Emargination (width): narrow. Prosternal process. Shape: subparallel; Sides: straight; Angles: obtuse; Angles (tips): blunt; Disc: with medial carina. Metasternum. Metasternal projection: flat. ABDOMEN. Tomentum: present. Basal ventrite. Modifications: absent. Pygidium. Apical margin: arcuate. Sternal groove. Shape on apex of last ventrite: arcuate. LEGS. Metatarsus. Length to metatibia: somewhat shorter. Metatarsomere 1. Length to following tarsomeres: subequal or longer than 2–4. GENITALIA. Aedeagus. Symmetry: symmetric; Shape: subparallel.

Variability. Body length: 9.6–10.5 mm. Without discernible variability except for the size. Sexual dimorphism. The species is known only from males. The male has prosternal process with obvious medial carina and protibiae with a comb of long setae on inner margin. These characters in Agrilus are a sexual dimorphism.
