Description of holotype. Body length: 4.3 mm. BODY. Shape: cuneiform, Color (dorsally): unicolored. HEAD. Size: very large, Modification: strongly convex. Vertex. Medial impression: present, Sculpture elements: rugae, Sculpture aspect: subparallel, Sculpture density: sparse, Sculpture intensity: superficial. 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: anteromedial and posteromedial, Lateral impressions (depth): shallow. Prehumerus. Development: filamentary, Shape: arcuate, Extent: to 1/2 of pronotal length, Modifications: with rudiment at anterior part, Anterior end: adjoining to lateral pronotal carina, Posterior end: distant from posterior pronotal angle or margin, Arc: moderate. 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: separate, Shape: arcuate. Pubescence. Extent: entire. STERNUM. Pubescence. Strip of erect pubescence: absent. Prosternal lobe. Distal margin: arcuately emarginate, Emargination (depth): shallow, Emargination (width): narrow. Prosternal process. Shape: slightly dilated, Sides: straight, Angles: obtuse, Angles (tips): blunt, Disc: impressed, with row of setae on sides, Projection (length): protruding distinctly beyond angles. Metasternum. Metasternal projection: impressed. ABDOMEN.
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. Aedeagus. Symmetry: symmetric, Shape: widest in apical part, Modifications: apex of medial lobe sharply pointed, parameres with obvious membraneous lobes.
Variability. The species is known only from the male holotype. Sexual dimorphism. In the male, sides of prosternal process with a row of setae.
Diagnosis. Agrilus qom sp. nov. is similar to Agrilus pusillesculptus Obenberger, 1940 by the size, by the color, by the habitus, by the large eyes protruding outside the outline of the head in dorsal view, and by the obvious pronotal lobe. The new species can be distinguished by the maximum width located at the anterior margin of the pronotum; by the shorter prehumerus, extending to half the pronotal length; by the separately arcuate elytral apices; and by the shape of the aedeagus ( Fig. 5I View FIGURES 5 ).
