Description of holotype. Body length: 4.3 mm. BODY. Shape: cuneiform, Build: robust, Profile: convex. HEAD. Medial impression: deep. Frons. Shape: flat. Vertex. Outline: markedly protruding head outline, Sculpture elements: rugae, Sculpture aspect: arcuate, Sculpture density: dense. Eyes. Size: smaller than half 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, Width: broad, Position: at level with anterior angles. Posterior angles. Shape: obtuse, Apex: blunt. Disk. Impressions: lateral only, Lateral impressions (depth): shallow, Lateral impressions (width): narrow. Prehumerus. Development: obsolete, Shape: arcuate, Extent: to 1/2 of pronotal length, Anterior end: distant from lateral pronotal carina, Posterior end: joined with posterior pronotal angle or margin, Arc: weak. Lateral carinae. Convergence: moderate, Junction: present, Narrowest point: at posterior angles. ELYTRA.
Apices. Arrangement: conjoint, Shape: arcuate. Pubescence. Character: with patches or spots of denser pubescence. STERNUM. Pubescence. Strip of erect pubescence: absent. Prosternal lobe. Distal margin: arcuately emarginate, Emargination (depth): deep. Prosternal process. Shape: subparallel, Sides: straight, Angles: obtuse, Angles (tips): blunt, Disc: flat. Metasternum. Metasternal projection: impressed. ABDOMEN. Basal ventrite. Modifications: with transverse protrusion. 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: longer than 2–3, but shorter than 2–4. GENITALIA. Aedeagus. Symmetry: symmetric, Profile: flat.
Variability. Body length: 4.3–5.3 mm. Elytral apices of paratypes are widely, separately arcuate. Sexual dimorphism. The males with frons golden-green. The females with frons golden-red; antennae shorter and ovipositor elongate.
Diagnosis. Agrilus yoa sp. nov. is similar to A. cicadelloides sp. nov. ( Fig. 3C View FIGURES 3 ) by the size, by the color, by the habitus, and by the shape of the pronotum. The new species can be distinguished by the absence of a cluster of long setae on head, by the less prominent prosternal lobe, and by the different pattern of the elytral pubescence.
