( Figs. 3C View FIGURE 3 , 5Q View FIGURE5 )

Description of holotype. Size 3.4 mm. Body. Shape: cuneiform; Build: robust; Profile: convex; Color (dorsally): unicolored. Head. Size: very large; Modification: strongly convex; Medial impression: absent, shallow. Vertex: Sculpture elements: rugae; Sculpture aspect: arcuate; Sculpture intensity: superficial. 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: slightly arcuate; Maximal width: at posterior margin; Anterior margin: narrower than posterior. Anterior lobe: Development: obvious; Shape: arcuate; Width: broad; Position: projecting beyond anterior angles. Posterior angles: Shape: rectangular; Apex: sharp. Disk: Convexity: strongly convex; Impressions: lateral only; Lateral impressions (depth): shallow; Lateral impression (width): broad. Prehumerus: Development: carinal; Shape: arcuate; Extent: to 1/2 of pronotal length; Anterior end: distant from lateral carina; Posterior end: joined with posterior angle or margin; Arc: obvious. Lateral carinae: Convergence: moderate; Junction: present; Narrowest point: at posterior 1/5–1/4 of marginal carina. Scutellum: Size: robust. Elytra. Color: unicolored; Humeral carina: absent. Apices: Arrangement: conjoint; Shape: arcuate. Pubescence: Color: unicolored; Extent: proximal and distal; Proximal (shape): quadrangular; Distal (shape): preapical. Sternum. Prosternal lobe: Size: large; Distal margin: angulately emarginate; Emargination (depth): deep; Emargination (width): wide. Prosternal process: Width: wide; Shape: subparallel; Sides: straight; Angles: obtuse; Angles (tips): sharp; Disc: flat; Projection (length): protruding distinctly beyond angles. Metasternum: Metasternal projection: flat. Abdomen. Pygidium: Apical margin: arcuate. Last ventrite: Disk: impressed. Sternal groove: Extent: on apical ventrite; Shape on apex of last ventrite: arcuately sinuate; Sinuosity (delimitation): angulate; Sinuosity (depth): markedly deep; Sinuosity (width): markedly wide. Legs. Metatarsus: Length to metatibia: distinctly shorter. Tarsomere 1: Length to following tarsomeres: shorter or subequal to 2–3. Genitalia. Aedeagus ( Fig. 5Q View FIGURE5 ): Symmetry: symmetric; Shape: widest in basal part; Modifications: markedly bent.

Variability. Size: 3.3–3.8 mm. Sexual dimorphism. The male has golden –green frons, cluster of setae on apex of metatibiae and comb of erect setae on ventral side of metatarsomere 1 and at anterior margin of each ventrite.

Diagnosis. By habitus, Agrilus vogti   sp. nov. is very similar to A. korbicola   sp. nov. ( Fig. 2C View FIGURE 2 ), but it differs mainly by very distinct shape of aedeagus ( Fig. 5Q View FIGURE5 ).
