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): 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), but it differs mainly by very distinct shape of aedeagus ( Fig. 5Q).
