Agrilus mus sp. nov.

( Figs. 1B , 2D )

Description of holotype. Length: 6.1 mm. BODY. Shape: subparallel, Profile: convex, Color (dorsally): unicolored. HEAD. Size: very large, Modification: strongly convex. Vertex. Medial impression: absent, Sculpture elements: punctures, Sculpture density: sparse, Sculpture intensity: rough. Eyes. Size: larger than half width but smaller than width of vertex (dorsal view), Lower margin: in line or below antennal socket, Median orbit: converging ventrally. Antennae. Serration: from antennomere 4. PRONOTUM. Shape: visually transverse, Sides: slightly arcuate, Maximal width: at posterior margin, Anterior margin: narrower than posterior. Anterior lobe. Development: obvious, Shape: arcuate, Position: projecting beyond anterior angles. Posterior angles. Shape: rectangular, Apex: sharp. Disk. Impressions: medial and lateral, Medial impression: entire, Lateral impressions (depth): deep. Prehumerus. Development: carinal, Shape: arcuate, Extent: to 1/3 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. Arrangement: conjoint, Shape: arcuate.

Pubescence. Extent: entire except glabrous part at distal half. STERNUM. Pubescence. Strip of erect pubescence: extending from prosternal lobe to metasternum. Prosternal lobe. Distal margin: arcuately emarginate, Emargination (width): wide. Prosternal process. Shape: markedly dilated, Sides: straight, Angles: obtuse, Angles (tips): blunt, Disc: flat, Projection (length): protruding distinctly beyond angles. Metasternum. Metasternal projection: flat. ABDOMEN. Basal ventrite. Modifications: with tubercle(s). Pygidium. Apical margin: arcuate. Sternal groove. Shape on apex of last ventrite: arcuately sinuate, Sinuosity (depth): markedly deep. LEGS.

Metatarsus. Length to metatibia: about as long or longer. Metatarsomere 1. Length to following tarsomeres: subequal or longer than 2–4. GENITALIA. Aedeagus. Symmetry: symmetric, Shape: widest in apical part, Modifications: apex of medial lobe sharply pointed.

Variability. Body length: 5.8–6.3 mm. Without discernible variability except for the size. Sexual dimorphism. The species is known only from males.

Diagnosis. The species is similar to A. hastulifer (Ratzeburg, 1837) by the habitus, by the size, and by the pair of tubercles on basal ventrite in male. It can be distinguished by the following male characters: the width of eye is considerably narrower than the width of vertex (dorsal view), the pronotal lobe extends beyond anterior pronotal angles, the maximal width of pronotum is in the middle, the pronotal disk has inconspicuous medial impression, the anterior end of prehumerus is adjoining to lateral pronotal carina, and the elytral pubescence is more extensive and not distinctly delimited to anterior and posterior half than that in A. hastulifer .
