Description of holotype. Body length: 4.1 mm. BODY. Shape: subparallel, Profile: convex, Color (dorsally): unicolored. HEAD. Size: very large, Modification: strongly convex. Vertex. Shape: markedly convex, Medial impression: present, Sculpture elements: rugae, Sculpture aspect: arcuate, Sculpture density: dense. Eyes. Size: subequal or larger than width of vertex (dorsal view), Lower margin: in line or below antennal socket, Median orbit: subparallel. Antennae. Serration: from antennomere 4. PRONOTUM. Shape: visually elongate or square, Sides: slightly arcuate, Maximal width: at anterior margin, Anterior margin: wider than posterior. Anterior lobe. Development: obvious, Shape: arcuate, Width: broad, Position: at level with anterior angles. Posterior angles. Shape: obtuse, Apex: sharp. Disk. Impressions: medial and lateral, Medial impression: entire, Lateral impressions (depth): shallow. Prehumerus. Development: carinal, Shape: arcuate, Extent: to 1/2 of pronotal length, Anterior end: adjoining to lateral pronotal carina, Posterior end: joined with posterior pronotal angle or margin, Arc: weak. Lateral carinae. Convergence: moderate, Junction: present, Narrowest point: at posterior 1/5–1/4 of marginal carina. ELYTRA. Color: unicolored, Humeral carina: absent. Apices. Shape: arcuate. Pubescence. Extent: proximal and distal, Proximal (shape): triangular, Distal (shape): preapical. STERNUM. Pubescence. Strip of erect pubescence: absent. Prosternal lobe. Size: narrow, Distal margin: arcuately emarginate, Emargination (depth): shallow, Emargination (width): wide. Prosternal process. Shape: slightly dilated, Sides: straight, Angles: obtuse, Angles (tips): blunt, Disc: impressed, Projection (length): protruding distinctly beyond angles. Metasternum. Metasternal projection: flat. ABDOMEN. Basal ventrite. Modifications: with tubercle(s). Last three ventrites. Modifications: with patches of erect pubescence. Pygidium. Apical margin: arcuate. Sternal groove. Shape on apex of last ventrite: arcuately sinuate, Sinuosity (depth): markedly deep. LEGS. Metafemora. Modifications: with comb of setae on inner margin. Metatibiae. Modification: with comb of setae on inner side. Metatarsus. Length to metatibia: distinctly shorter. Metatarsomere 1. Length to following tarsomeres: subequal or longer than 2–4. GENITALIA. Aedeagus. Symmetry: symmetric, Shape: widest in basal part.
Variability. The species is known only from the male holotype.
Diagnosis. Agrilus kon sp. nov. is similar to A. relegatus Curletti, 1990 by the size, by the habitus, and by the color. The new species can be distinguished by the shape of the aedeagus, which is strongly enlarged apically (Fig. 5L), and by very specific male sexual characters in the form of a pair of tubercles on the basal ventrite, by clusters of fine, erect pubescence in the middle of the last three ventrites, and by a row of setae on the inner margin of the metatibiae and metafemora.
