(Figs. 2D, 5J)
Description of holotype. Body length: 4.4 mm. BODY. Shape: cuneiform, Posterior tapering part: long with narrow apex, Color (dorsally): unicolored. HEAD. Modification: strongly convex. Vertex. Medial impression: present, Sculpture elements: rugae, Sculpture aspect: arcuate, Sculpture density: dense. Eyes. Size: larger than half width but smaller than width of vertex (dorsal view), Shape: markedly protruding head outline, Lower margin: in line or below antennal socket, Median orbit: subparallel. Antennae. Serration: from antennomere 4. PRONOTUM. Shape: visually transverse, Sides: markedly arcuate, Maximal width: at middle, Anterior margin: subequal to 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, Lateral impressions (width): broad.
Prehumerus. Development: filamentary, Shape: arcuate, Extent: beyond 1/2 of pronotal length, Modifications: with rudiment at anterior part, Anterior end: adjoining to lateral pronotal carina, Posterior end: joined with posterior pronotal angle or margin, Arc: moderate. 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. Pubescence. Extent: proximal and distal, Proximal (shape): quadrangular, Distal (shape): preapical. STERNUM. Pubescence. Strip of erect pubescence: absent. Prosternal lobe. Position to sternum: markedly declivous, Distal margin: arcuately emarginate, Emargination (width): wide. Prosternal process. Shape: subparallel, Sides: straight, Angles: obtuse, Angles (tips): blunt, Disc: impressed, Projection (length): protruding distinctly beyond angles. Metasternum. Metasternal projection: flat. ABDOMEN. Basal ventrite. Modifications: absent. Pygidium. Apical margin: arcuate. Sternal groove. Shape on apex of last ventrite: arcuately sinuate, Sinuosity (depth): markedly deep. LEGS. Metatarsus. Length to metatibia: distinctly shorter. Metatarsomere 1. Length to following tarsomeres: subequal or longer than 2–4. GENITALIA.
Aedeagus. Symmetry: feebly asymmetric, Profile: flat, Modifications: apex of medial lobe markedly obtuse.
Variability. Body length: 4.3–4.4 mm. The species is known only from males. Sexual dimorphism. The male has a medial strip of erect pubescence from the prosternal lobe to the metasternal projection.
Diagnosis. Agrilus jum sp. nov. is similar to A. friebi Obenberger, 1922 by the size, by the color, and by the habitus, but it can be distinguished by having a subparallel prosternal process and a feebly asymmetric aedeagus (Fig. 5J).
